Abstract
BACKGROUND Given changes in marijuana regulations, retail, and products and potential impact on use, we examined young-adult perceptions of different modes of use, the proportion using via different modes (e.g. smoking, vaping, ingesting), and associations with the use levels and stability of use over time. METHODS We analyzed baseline and one-year follow-up survey data (Fall 2018-2019) among 3,006 young adults (ages 18-34) across six metropolitan areas (Atlanta, Boston, Minneapolis-St. Paul, Oklahoma City, San Diego, Seattle). Measures included marijuana use frequency and mode, sociodemographics, other substance use, and social influences. RESULTS Participants' rated the following modes of use as: least harmful/addictive: topicals, oral pills, joint/bowl; most socially acceptable: joint/bowl, edibles/beverages, vaporized; and most harmful/addictive and least acceptable: wrapped, vaped, or waterpipe/bong with tobacco. Baseline past-month use prevalence was 39.2% (n = 1,178). Most frequent use mode was smoking (joints/bowls/cigar papers; 54.0%), vaping (21.8%), via pipe/bong (15.1%), and ingesting (9.1%). Multinomial logistic regression indicated that participants in states with legalized marijuana retail were at greater odds for using via modes other than smoking; participants more frequently using were at greater odds for using via pipe/bong (vs. smoking) (ps < .001). Regarding most frequent mode across time, most consistent was pipe/bong (53.3%), followed by smoking (49.3%), vaping (44.5%), and ingesting (32.9%). Past-month abstinence at follow-up was most common among those originally ingesting (34.3% abstinent), followed by smoking (23.6%), vaping (18.8%), and pipe/bong (14.8%). CONCLUSIONS Ongoing surveillance is needed to understand marijuana use patterns over time across different user groups (particularly by mode) and to inform interventions promoting abstinence.

Abstract
OBJECTIVE Given the rising rates of insufficient sleep and the popularity of marijuana, we investigated using marijuana as a sleep aid, marijuana use frequency, problematic marijuana use, and sleep problems. Participants: Participants included a convenience sample of college students who endorsed using marijuana in the past year from May to December 2013 (N = 354; 68% female, 57% White). Methods: Path analyses investigated if using marijuana to sleep predicted: (1) marijuana use outcomes and (2) sleep problems; and if sleep problems predicted marijuana use outcomes. Results: Using marijuana to sleep was related to increased use and problematic use, as well as worse sleep efficiency. Daytime dysfunction related to sleepiness was associated with elevated levels of marijuana use and problematic use. Similar associations were found across sex and race. Conclusions: College students should be informed of the potential misconceptions between marijuana and improved sleep and provided with evidence-based alternatives to improve their sleep.

Abstract
BACKGROUND Prevention of early age initiation of cannabis use is a national priority, highlighting the importance of identifying cannabis-specific attitudes, norms, and perceived behavioral control in relation to initiation age. METHODS Data were from the NEXT Generation Health Study, a national longitudinal sample of US adolescents followed from 10th grade (N = 1850). Cannabis-specific attitudes, norms, and perceived behavioral control were assessed at 10th grade. Age of first use was reported retrospectively 2-3 years after high-school and participants were categorized as early initiators (<14 years; 3.8%), high-school (HS) initiators (14-18 years; 35.6%), post-HS initiators (>18 years; 8.3%), or never users (52.3%). RESULTS Relative to never users, early initiators were more likely to endorse pro-use attitudes (AOR [adjusted odds ratio] = 2.39, 95% confidence interval [CI] = 1.27-4.50), less disapproving parental attitudes toward use (AOR = 2.50, 95% CI = 1.45-4.28), higher cannabis use among friends (AOR = 3.81, 95% CI = 2.21-6.60), and higher ease of access (AOR = 2.10, 95% CI = 1.14-3.87); HS initiators were similarly more likely to report less disapproving attitudes toward use (AOR = 1.55, 95% CI = 1.25-1.91), higher cannabis use among friends (AOR = 2.81, 95% CI = 2.18-3.65), and higher ease of access (AOR = 1.66, 95% CI = 1.21-2.28). CONCLUSIONS Earlier cannabis initiation was associated with more favorable cannabis attitudes, subjective norms, and perceived behavioral control, highlight these variables as potential intervention targets.

Abstract
Background: Given that cannabis is the most commonly used illicit substance in the US, continuous research on patterns of cannabis use over the life course can help to ensure progress towards improving public health and reducing health inequalities across race/ethnicity. Thus, we examine racial/ethnic differences in cannabis use trajectories among males across two overlapping stages of the life course. Methods: We use data from two companion studies, the Rochester Youth Development Study (RYDS - a longitudinal cohort study that followed participants from adolescence into adulthood), and its intergenerational extension - the Rochester Intergenerational Study. For Life Stage 1, we consider cannabis use during the transition from adolescence to adulthood (spanning ages 13 to 33; 439 Black, 128 White, and 125 Hispanic males). Among these males who became fathers, we consider cannabis use during fatherhood (Life Stage 2 -spanning the period of time when their firstborn child was between the ages of 7 and 17-217 Black, 55 White, and 56 Hispanic males). Ordinal generalized estimating equations were specified to examine cannabis use trajectories during both stages of the males' lives. Results: No significant differences in cannabis use as a function of racial/ethnic group were found during the transition from adolescence to adulthood (Life Stage 1). All groups had a peak of cannabis use in the early to mid-20's followed by a decline in use. During fatherhood (Life Stage 2), cannabis use was stable for all groups, but Black fathers reported more frequent cannabis use on average than Hispanic fathers. Conclusions: The increase in cannabis use well past adolescence for all groups suggests the potential importance of intervention initiatives during the transition to adulthood. The more frequent use of cannabis by Black fathers warrants further study given the impact parental cannabis use can have on offspring.

Abstract
Introduction The prevalence of marijuana use has increased by about 16% since 2006, translating to approximately 200 million people worldwide. Being so widely used, long-term effects of marijuana use on cardiovascular health are largely unknown. Previous studies have had conflicting results, either showing marijuana use having a negative impact or no significant impact on cardiovascular health. This study aims to add evidence regarding the impact marijuana use has on the prevalence of cardiovascular disease. Methods This retrospective study was conducted using the Behavioral Risk Factor Surveillance System (BRFSS) database. Patients who completed the questionnaire and answered all questions in relation to marijuana use and the diagnosis of cardiovascular disease in 2017 were a part of this study. Subjects were excluded if they were children (<18 years old) or had missing data for marijuana use or cardiovascular disease. Age, gender, race/ethnicity, body mass index (BMI), income, exercise, tobacco use, alcohol use, and depression were all considered as potential confounders. Bivariate analysis was conducted to find an initial association between marijuana use and cardiovascular disease, which was followed by a multivariate regression analysis to adjust for confounders. Odds ratios and 95% confidence intervals were calculated. Results A total of 56,742 subjects were included in the analysis. The unadjusted bivariate analysis showed a reduced prevalence of cardiovascular disease in individuals using marijuana (OR 0.65, 95%CI [0.50-0.84]). After adjustment with all additional variables, an adjusted model showed a similar odds ratio, but statistical significance of the association was lost (OR 0.74, 95%CI [0.54-1.01]). Discussion A systematic review by Ravi et al in 2018, which looked at marijuana use, cardiovascular risk factors, and clinical outcomes concluded that there was insufficient data to make conclusions regarding the effect of marijuana use and negative long-term cardiovascular effects. Our study lends support to the notion that marijuana use does not have an association with cardiovascular disease. A limitation in our study was that there was missing data from the BRFSS questionnaire due to participants not fully answering all questions concerning cardiovascular disease and marijuana use. This decreased our sample size from 67,974 to 56,742 subjects. The missing participants led to a decrease in the power of our odds ratio, which may have impacted statistical significance of our results. Conclusion Although previous literature has shown that marijuana use has a negative impact on cardiovascular health, our study suggests that users and non-users of marijuana did not have an association with the prevalence of cardiovascular disease. Varying levels of support within the literature highlights the need for further research of this association.

Abstract
We determined the prevalence and correlates of cannabis use in Massachusetts after recreational use was passed, but before recreational cannabis stores opened. A cross-sectional, population-based survey of Massachusetts adults, age 18 years or older, (n = 3,022) was conducted in November-December, 2017. We estimated population-level prevalence and correlates of past 30-day cannabis use. 21.1% [95% CI: 18.6, 23.6] of Massachusetts adults reported past 30-day cannabis use. Among cannabis users, 56.0% [CI 49.1, 62.9] reported non-medical cannabis use, 15.5% [12.1, 18.9] reported medical cannabis use, and 28.5% [CI 22.3, 34.8] reported both types of use. Men were more likely than women to use cannabis (Risk Ratio: 1.3 [CI 1.1, 1.6]), as were young adults (18-25 years old), those with lower socioeconomic status, non-parenting individuals, those who used alcohol (1.9 [CI 1.4, 2.6]) or other substances (1.7 [CI 1.3, 2.4]), and residents of Western Massachusetts (2.0 [1.3, 3.0]; ref: Boston area), the Northeast (1.8 [CI 1.2, 2.7]), and the Southeast (1.8 [CI 1.1, 2.7]). Cannabis is widely used in Massachusetts, with varying prevalence rates by gender, age, socioeconomic status, poly-substance use, and region. Findings may inform public health efforts and serve as a baseline for measuring health and social impacts of opening retail cannabis stores.

Abstract
This study examined the relationship between perceived racial discrimination (PRD) and patterns of substance use. Data come from the 2001-2003 National Survey of American Life (N = 3,589). PRD was derived from the Major Experiences of Discrimination Scale. Multinomial logistic regression estimated the relationship between PRD and patterns of substance use (i.e., never/former, single-substance, dual-substance, and polysubstance [3+ substances]) based on six substances; effect modification by ethnicity and sex was assessed by stratification. Study findings indicated that PRD was associated with greater odds of lifetime and current polysubstance use. Results from the effect modification analyses suggested differential associations by ethnicity and sex.

Abstract
BACKGROUND The literature on psychosis-relevant outcomes in cannabis users does not adequately address the confounding effects of other substance use/misuse and psychiatric disorders. METHODS We studied a unique population for whom cannabis use is central and necessary to their way of life. They are forbidden from using other substances, including tobacco and alcohol. Their use of cannabis is heavy, chronic, and begins early. The cases were compared with matched controls who did not use cannabis, alcohol, or drugs. The controls were from the same location and shared similar beliefs and lifestyle, except for cannabis use. Attenuated psychosis-relevant phenomena were assessed with the Schizotypal Personality Questionnaire (SPQ) and cognitive functioning with a culture-neutral computerized cognitive battery. RESULTS Fifteen cases and 12 matched controls were studied. The cases averaged >30 000 lifetime cannabis exposures. Relative to controls, the cases had significantly higher mean (s.d.) SPQ scores 24 (14.32) v. 13 (8.92), p = 0.031; and poorer cognitive performance, reflected by a lower mean (s.d.) composite cognitive score -0.23 (0.32) v. +0.28 (0.52), p = 0.03. Moderate to large effect sizes were noted for differences in tests of attention, psychomotor speed, working memory, cognitive flexibility, visuo-spatial processing, and verbal memory. A subsample of cases had higher SPQ scores and worse cognitive performance than their siblings not using cannabis. CONCLUSION Heavy, chronic, and early cannabis use that is not confounded by other drug use is associated with psychosis-relevant phenomena and cognitive deficits. The findings are relevant to the evolving attitudes and laws about cannabis.

Abstract
Emerging adult African American females are at increased risk for cannabis use disorders. Ecological models suggest that African Americans' increased risk for substance use disorders and associated adverse outcomes may result from chronic exposure to contextual disadvantages, such as living in economically deprived and disorganized communities. However levels of vulnerability for developing cannabis use disorders vary, even among residents of disadvantaged neighborhoods. Therefore, studies focused on within group differences are necessary. This study examined the relationship between frequency of marijuana use and perceived neighborhood disorder. The sample included 117 African American emerging adult females (Mage = 23.6 ± 3.4). After providing informed consent, participants completed a semi-structured interview that included the Neighborhood Environment Scale and a self-report measure of marijuana use. Additionally, participants provided a urine sample that was tested for the presence of psychoactive drugs. 46% tested positive for marijuana and 45% reported using marijuana in the past 30 days. 27% reported frequent/heavy use. Results from multinomial logistic regression analysis indicated a significant relationship between perceived neighborhood disorder and heavy marijuana use (AOR = 3.3; 95% CI = 1.06 - 10.29). Findings suggest African American emerging adult female residents of economically disadvantaged neighborhoods who appraise their environments as disorganized may be at heighten risk for problematic marijuana use and should be targeted for intervention. Moreover, the findings support the need for multi-systems interventions. As policy makers consider the legalization of marijuana, it is important that differences in marijuana use behaviors and negative outcomes across groups and contexts are taken into consideration.

Abstract
BACKGROUND More United States adolescents now report high-frequency marijuana use than similar use levels of alcohol or tobacco. Increased high-frequency use raises questions such as (a) is frequent use likelihood growing among adolescents who experiment with use? (b) Is such change observed equally across sex and racial/ethnic subgroups? (c) Have sociodemographic and other covariate associations with frequent use changed over time? METHODS Data were obtained from 649,505 12th grade students participating in the cross-sectional, nationally-representative Monitoring the Future study from 1976 to 2019. Historical trends were modeled for any and frequent (20+ occasions) past 30-day marijuana use among all students and lifetime users, and lifetime user sex and racial/ethnic subgroups. Multivariable logistic regression estimates from 1989 to 1993 (lowest prevalence years) versus 2015-2019 (most recent years) were compared to examine covariate association changes with frequent use. RESULTS Among all students, recent linear trends in any and frequent marijuana use were not significantly different from zero (0.023 [SE 0.156] and 0.036 [0.073], respectively); frequent use among lifetime users increased (0.233 [0.107], p = 0.048). Among lifetime users, the increase was stronger for male than female students, and for minority versus White students. Significant association changes with race/ethnicity, parental education, and perceived risk were observed. CONCLUSIONS The proportion of adolescent lifetime marijuana users reporting current frequent marijuana use increased, and is now at near-record levels. Increases were particularly strong among males and minority students. There appears to be an increasing likelihood that adolescents who experiment with marijuana use may progress to frequent use.

Abstract
OBJECTIVES To examine national trends and contributing factors of cannabis-associated emergency department visits in the United States. METHODS This pooled serial cross-sectional study used a hierarchical multivariable analysis on emergency department visit adjusting for year, patient and hospital characteristics. We analyzed 2006 to 2014 National Emergency Department Sample data that identified cannabis-associated emergency department visits among patients aged 12 years or older (n = 265,128). RESULTS Cannabis-associated emergency department visits per 100,000 emergency department discharges increased monotonically (annually by 7%). As compared with privately insured patients, Medicare, and Medicaid, uninsured patients were over 40% more likely to visit emergency department. The age group 12 to 17 had the highest risk of emergency department visits and the risk monotonically declined as the age increased. Hospitals in the South region showed the highest cannabis-associated emergency department utilization, yet trends of cannabis-associated emergency department visits increased in the West region from 15.4% to 26% over time. CONCLUSIONS Cannabis-associated emergency department visits increase monotonically over time. Although vulnerable persons were identified, additional policy or regional factors should explore risks of emergency department visits associated with cannabis use.

Abstract
OBJECTIVES Due to the elevated rates of cigarette use and marijuana use within the criminal justice system, it is critical to develop a stronger understanding of tobacco and marijuana co-use among this population to inform future interventions. METHODS This study is a secondary analysis of baseline data from a smoking cessation randomized clinical trial of adults (n = 500) in a community correction program. Participants were classified as using cigarettes only or both cigarettes and marijuana through either self-report or positive urine drug screening. Demographics and measures regarding legal, drug use, smoking, mental health, and interpersonal histories were assessed. Logistic regression analyses were conducted to assess factors associated with co-use. RESULTS Among adults who smoked cigarettes, 25% reported current marijuana use. Individuals who used both cigarettes and marijuana were more likely than those who only used cigarettes to be African American (80%), male (73.6%), and younger (M = 32.4 [SD = 11.0]). Increasing difficulties with last quit attempt was associated with a reduction in the likelihood of co-use (odds ratio [OR] 0.75, 95% confidence interval [CI] 0.60-0.94, P < 0.05), and benzodiazepine (OR 9.09, 95% CI 1.25-65.94, P < 0.05) and opioid (OR 8.17, 95% CI 2.03-32.93, P < 0.01) use was significantly associated with an increased likelihood of co-use. CONCLUSIONS This study identified several factors that are associated with an increased risk of cigarette and marijuana co-use among a community correction population. These findings will be valuable for informing targeted prevention and treatment interventions.

Abstract
Purpose of Review This review summarizes (1) recent trends in delta-9-tetrahydrocannabionol [THC] and cannabidiol (CBD) content in cannabis products, (2) neurobiological correlates of cannabis use on the developing adolescent brain, (3) effects of cannabis on psychiatric symptoms and daily functioning in youth (i.e., academic performance, cognition, sleep and driving), (4) cannabis products used to relieve or treat medical issues in youth, and (5) available treatments for cannabis use disorder in adolescence. Recent findings Despite marked increases in THC content and availability of cannabis, there has been a decline in perceived risk and an increase in use of THC extract products among youth in the United States. The primary psychiatric symptoms associated with cannabis use in youth are increased risk for addiction, depressive, and psychotic symptoms. Cannabis alters endocannabinoid system function which plays a central role in modulating the neurodevelopment of reward and stress systems. To date, few studies have examined neurobiological mechanisms underlying the psychiatric sequalae of cannabis exposure in youth. Adolescent cannabis exposure results in impaired cognition, sleep, and driving ability. There are very limited FDA-approved cannabinoid medications, none of them supporting their use for the treatment of psychiatric symptoms. Behavioral therapies are currently the mainstay of treating cannabis misuse, with no pharmacotherapies currently approved by the FDA for cannabis use disorder in youth. Summary Here, we summarize the most up-to-date knowledge on the neurobiological psychiatric, and daily function effects of the most commonly used cannabinoids, delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). We then review FDA approved medical use of cannabinoid treatments as well as pharmacological and psychological treatments for cannabis use disorder in youth. Our current understanding of the effects of cannabis on the developing brain and treatments for cannabis misuse in youth remain limited. Future research aimed at examining the neurobiological effects of cannabis, with objective measures of exposure, over the course of pediatric development and in relation to psychiatric symptoms are needed.

Rural-urban differences in cannabis detected in fatally injured drivers in the United States. Prev Med 2020; 132:105975. [PMID: 31899254 DOI: 10.1016/j.ypmed.2019.105975] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Revised: 12/17/2019] [Accepted: 12/28/2019] [Indexed: 11/22/2022]
Abstract
While there is a vast literature on rural and urban differences in substance use, little is known in terms of cannabis positive drug tests among fatally injured drivers. In the present study, we examined rural-urban differences in cannabis detected in fatally-injured drivers. Data were drawn from the 2015-2017 Fatality Analysis Reporting System. Multivariable logistic regression was performed to examine rural-urban differences in the percentage of cannabis detected in fatally-injured drivers. Analyses were stratified by rural-urban classification and sex. A positive cannabis test in fatally-injured drivers was more prevalent in urban locations. Compared to fatally-injured drivers in rural locations, urban drivers had higher odds of a positive test for cannabinoids (aOR: 1.21, 95% CI 1.14-1.28). Non-Hispanic Black drivers had higher odds of testing positive for cannabinoids (aOR: 1.43, 95% CI 1.31-1.55). Those aged at least 25 years had lower odds of a positive test for cannabinoids. Drivers involved in a weekend nighttime crash (aOR: 1.14, 95% CI 1.03-1.26) and weekday nighttime (aOR: 1.15, 95% CI 1.05-1.26) had higher odds of testing positive for cannabinoids compared to drivers involved in a weekend daytime crash. Results showed significant rural-urban differences in the prevalence of cannabis detected in fatally-injured drivers.

Abstract
BACKGROUND After many years of legal struggles for the legalisation of recreational use of cannabis, the Constitutional Court of South Africa ruled in favour of the applicants in September 2018. Although the ruling issued caution regarding the social challenges accompanying this legalisation, it did not address how the country would deal with the societal consequences of this ruling. AIM The aim of this article was to discuss the social and public health implications of the legalisation of recreational cannabis on South Africa. METHODS Literature review on the social, health and legal impacts of legalisation of cannabis, considering experiences of other countries that have legalised cannabis. RESULTS The legalisation brings a range of significant negative consequences, which include an expected increase in the number of users and the subsequent undesirable effects on the physical, mental and social health of communities. CONCLUSION In terms of financial, infrastructural and human resources, South Africa cannot afford the consequences of the legalisation of recreational cannabis. Poor communities, children and the youth will carry the brunt of the scourge of cannabis use.

Social media photos of substance use and their relationship to attitudes and behaviors among ethnic and racial minority emerging adult men living in low-income areas. J Adolesc 2019; 77:152-162. [PMID: 31731226 DOI: 10.1016/j.adolescence.2019.10.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2018] [Revised: 10/24/2019] [Accepted: 10/30/2019] [Indexed: 12/14/2022]
Abstract
OBJECTIVES Emerging adult minority males have inequitable negative consequences from substance abuse. They are also frequent users of social media, logging into popular sites up to 25 times per week on average, so there may be opportunities to use these technologies for better understanding and preventing substance use behaviors. Through mobile phone monitoring, this study examined how social media sites are used to post substance use-related images and how posting such images is related to behaviors and attitudes. It also explored how self-presentation of masculinity norms, such as coolness and toughness, was related to posting of substance use-related photos. METHODS Instagram and/or Twitter posts of 65 minority males aged 18-25 living in low-income areas were monitored for three months using phone tracking software. Over 2200 posted images were content analyzed to determine if they were related to alcohol or marijuana and if they displayed masculinity norms. Behavioral interviewing was also used to examine alcohol and marijuana attitudes, use, and problematic use. Analyses utilized t-tests and multiple and logistic regression. RESULTS Many participants posted at least one substance use-related photo and a strong majority were exposed to such images through their network. Individuals who posted substance use-related images had more "followers." Posting substance-use related photos was related to marijuana use attitudes, behaviors, and problem behaviors, as well as depictions of toughness in photos. CONCLUSIONS Social media monitoring has potential for use in identifying individuals at-risk for substance abuse and those who may be perpetuating unhealthy substance use norms.

Abstract
Cannabis use has been rising despite recognition of the negative consequences associated with heavy use. The severity of these consequences has been shown to differ across racial/ethnic groups, even when controlling for consumption levels. The present study conducted an item response theory (IRT) analysis of the Cannabis Use Disorders Identification Test (CUDIT) to better understand the patterns of problematic cannabis use and their relation with other substance use across ethnic groups in the Healthy Life in an Urban Setting (HELIUS) study. CUDIT responses from 1,960 cannabis-using African Surinamese, South-Asian Surinamese, Dutch, Moroccan, and Turkish ethnic origin participants were used to test for differential item functioning (DIF) within an IRT framework. After restricting the sample to men because of low frequency of use among women, several instances of uniform DIF were identified. Multiple-group IRT analysis yielded a harmonized cannabis use phenotype that was used to estimate ethnic group differences in problematic cannabis use and its relation to alcohol and tobacco co-use. These analyses suggested that cannabis users from certain ethnic minority groups experienced higher rates of problematic use than the majority group despite lower rates of cannabis use. Further, cannabis and tobacco use were positively related across groups, whereas only ethnic minority groups showed a positive relation between cannabis and alcohol use. These results demonstrate the importance of accounting for DIF when examining group differences in problematic cannabis use, and support prior evidence suggesting that certain ethnic minority groups may be more likely to experience problematic cannabis use and alcohol co-use relative to the majority group.

Abstract
To examine trends and contributing factors of opioid, heroin, and cannabis-associated emergency department (ED) visits in Nevada.The 2009 to 2017 Nevada State ED database (n = 7,950,554 ED visits) were used. Use of opioid, heroin, and cannabis, respectively, was identified by the International Classification of Diseases, 9th & 10th Revisions. Three multivariable models, one for each of the 3 dependent variables, were conducted. Independent variables included year, insurance status, race/ethnicity, use of other substance, and mental health conditions.The number of individuals with opioid, heroin, cannabis-associated ED visits increased 3%, 10%, and 23% annually from 2009 to 2015, particularly among 21 to 29 age group, females, and African Americans. Use of other substance (odds ratio [OR] = 3.91; 95% confidence interval [CI] = 3.84, 3.99; reference - no use of other substance), mental health conditions (OR = 2.48; 95% CI = 2.43, 2.53; reference - without mental health conditions), Medicaid (OR = 1.41; 95% CI = 1.38, 1.44; reference - non-Medicaid), Medicare (OR = 1.44; 95% CI = 1.39, 1.49; reference - non-Medicare) and uninsured patients (OR = 1.52; 95% CI = 1.49, 1.56; reference - insured) were predictors of all three substance-associated ED visits.With a steady increase in trends of opioid, heroin, and cannabis-associated ED visits in recent years, the main contributing factors include patient sociodemographic factors, mental health conditions, and use of other substances.

Abstract
Background The last two decades have seen tremendous changes in the U.S. environment surrounding drugs. Driving under the influence of drugs is a growing public health hazard. The present study examined trends in drug involvement in fatally-injured drivers in the U.S. Methods Data were drawn from the 2007–2017 Fatality Analysis Reporting System. Cochran–Armitage tests were performed to assess the statistical significance of changes in the yearly prevalence of positive drug tests in fatally-injured drivers over time. In addition, analyses were stratified by sex, race, and age. Results The yearly prevalence of positive drug tests in fatally-injured drivers increased significantly from 20.7% in 2007 to 30.7% in 2017, with results showing a higher prevalence among males, those aged 21–44, and Whites. The gap between Blacks and Whites narrowed in 2017. There was a decline in the yearly prevalence in all age groups between 2016 and 2017, although the decrease in the 21–44 age group was much smaller than other age groups. Among drivers who tested positive for drugs, 34.6% had a blood alcohol concentration (BAC) above the threshold of per se evidence for impaired driving, and 63% had a BAC below the threshold. Conclusions Our results indicate that the overall yearly prevalence of fatally-injured drivers who tested positive for drugs increased significantly from 2007 to 2017, with similar results found for subgroups. Findings further highlight that drugged driving remains a public health priority, and more action is needed to stem this disturbing trend.

Abstract
Background: Our study is the first using a national sample to examine the severity of Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) cannabis use disorder (CUD) in sexual minorities. Drawing from current literature, we expected that bisexual individuals would have the highest prevalence of CUD and the most severe form of CUD. Methods: The National Epidemiological Survey on Alcohol and Related Conditions-III (NESARC-III; 2012-2013) provides a nationally representative adult sample (N = 36,309), including one of the largest samples of sexual minorities. The NESARC-III is large enough to compare subpopulations of sexual minorities on dimensions of substance use disorder severity. Results: Lesbians and gay men were more likely to report mild CUD, whereas bisexuals and respondents "not sure" of their sexual identity were more likely to report severe CUD when compared with heterosexuals. Sexual minorities and heterosexuals who reported lifetime use of medical cannabis had higher odds of having a severe CUD. Sexual minorities had significantly higher odds of lifetime medical cannabis use (adjusted odds ratio [AOR] = 2.39, 95% confidence interval [CI] = 1.42-3.66, P < .001) when compared with heterosexuals, with bisexuals having the highest odds (AOR = 2.81, 95% CI = 1.66-4.75, P < .001). Conclusions: Sexual minorities have the highest odds compared with heterosexuals of developing any CUD. Moreover, the higher rates of severe CUD among bisexuals and those "not sure" have implications for drug prevention with these particularly high-risk groups. It appears that lifetime medical marijuana use may play a role in the development of CUD, although more rigorous measures of medical marijuana use are needed to determine the nature of the relations.

Abstract
Objective The aim of this study was to observe the trends of intractable vomiting and cannabis use disorder (CUD) with demographic characteristics, medical and psychiatric comorbidities, and hospitalization outcomes. Methods We conducted a retrospective cohort study using the nationwide inpatient sample (2010 to 2014). Patients aged 16-50 years discharged with a primary diagnosis of intractable vomiting and CUD were included (N = 9,601). We used the linear-by-linear association chi-square test and independent-sample T-test for measuring the categorical and continuous data, respectively. Results The number of intractable vomiting hospitalizations with CUD had an increasing trend (P < 0.001) with a 28.6% increase over five years. About half of the study population included young (16-30 years, 48.4%) males (57.2%). There was a decreasing trend (P = 0.041) in the prevalence of intractable vomiting with CUD in non-Hispanic Whites and Blacks, whereas there was 778% increase in Hispanics. The mean length of stay was 3.2 days which had a decreasing linear trend, and total hospital charges showed an increasing trend (P < 0.001), averaging $22,890. Electrolyte disorders (55.3%), hypertension (25.3%), chronic lung disease (11.9%), and deficiency anemia (10.3%) constituted the majority of comorbidities, with anemia showing a statistically significant increasing trend (P = 0.004). Anxiety disorders increased from 20.8% to 30.8% over five years, whereas depression decreased from 19.2% to 16.4% (P < 0.001). Concomitant tobacco abuse/dependence was present in 41.2% of patients with CUD. Conclusion The results of our study show that the intractable vomiting hospitalizations related to CUD have increased significantly over a five-year period. The general public and healthcare practitioners should be made aware of the paradoxical gastrointestinal side effects of cannabis.

Abstract
Objective: Our study aimed to compare the demographic characteristics of conduct disorder (CD) inpatients versus other psychiatric inpatients in children and adolescents, and assess the association between conduct disorder patients and the spectrum of substance use disorders (SUD). Methods: We included 800,614 psychiatric adolescent (12–18 years) inpatients, and this included 8885 inpatients (1.1%) primarily for conduct disorder in the Nationwide Inpatient Sample (2010–2014). ICD-9 codes were used to detect SUD, and a logistic regression model was used to evaluate the odds ratio (OR) for SUD in conduct disorder inpatients. Results: A higher proportion of conduct disorder inpatients were of 12–15 years of age (62.6%), male (64.4%), and White (45.7%). The lower median household income was correlated with a higher prevalence of conduct disorder (36.4%). Among SUD, cannabis use (23.7%) was most prevalent in conduct disorder inpatients followed by tobacco and alcohol use (10.1% each). Conduct disorder inpatients have 1.7-fold higher odds (95% confidence interval (CI) 1.52–1.82) for alcohol use and 1.4-fold higher odds (95% CI 1.31–1.49) for cannabis use compared to the non-conduct disorder inpatients. Cannabis use was seen significantly in adolescents (49.1%, 12–15 years), male (75.6%), and African Americans (45.6%). Conclusion: Conduct disorder inpatients have a higher risk of comorbid SUD compared to other psychiatric illnesses. The most common substance to be abused is cannabis followed by tobacco and alcohol. Varying pattern of substance use was seen by demographics and these predictors may help the clinicians for early diagnosis and treatment to improve overall health-related quality of life.

[PMID: 31099175 PMCID: PMC6726116 DOI: 10.1111/gbb.12580] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2019] [Revised: 04/19/2019] [Accepted: 05/11/2019] [Indexed: 02/07/2023]
Abstract
Genetic influences on alcohol and drug dependence partially overlap, however, specific loci underlying this overlap remain unclear. We conducted a genome-wide association study (GWAS) of a phenotype representing alcohol or illicit drug dependence (ANYDEP) among 7291 European-Americans (EA; 2927 cases) and 3132 African-Americans (AA: 1315 cases) participating in the family-based Collaborative Study on the Genetics of Alcoholism. ANYDEP was heritable (h 2 in EA = 0.60, AA = 0.37). The AA GWAS identified three regions with genome-wide significant (GWS; P < 5E-08) single nucleotide polymorphisms (SNPs) on chromosomes 3 (rs34066662, rs58801820) and 13 (rs75168521, rs78886294), and an insertion-deletion on chromosome 5 (chr5:141988181). No polymorphisms reached GWS in the EA. One GWS region (chromosome 1: rs1890881) emerged from a trans-ancestral meta-analysis (EA + AA) of ANYDEP, and was attributable to alcohol dependence in both samples. Four genes (AA: CRKL, DZIP3, SBK3; EA: P2RX6) and four sets of genes were significantly enriched within biological pathways for hemostasis and signal transduction. GWS signals did not replicate in two independent samples but there was weak evidence for association between rs1890881 and alcohol intake in the UK Biobank. Among 118 AA and 481 EA individuals from the Duke Neurogenetics Study, rs75168521 and rs1890881 genotypes were associated with variability in reward-related ventral striatum activation. This study identified novel loci for substance dependence and provides preliminary evidence that these variants are also associated with individual differences in neural reward reactivity. Gene discovery efforts in non-European samples with distinct patterns of substance use may lead to the identification of novel ancestry-specific genetic markers of risk.

Abstract
(1) Background: Cannabis and tramadol are featuring prominently in Egypt; however, their prevalence in first episode psychosis is still uncertain. We aimed at determining the prevalence of cannabis and tramadol among the first-psychotic episode in Egyptian inpatients and to compare the demographic and psychopathological profiles of substance abusers versus patients with the comorbid diagnosis. (2) Methods: Patients presented with psychotic episode and admitted to Mansoura Psychiatric Department were recruited. Diagnosis of psychiatric illness and drug/substance use was carried out using the Diagnostic and Statistical Manual- Fourth Edition (DSM-IV) criteria. Standard urine tests and thin layer chromatography were performed to detect cannabis and tramadol. (3) Results: Of the 100 subjects in the study, the majority (55.6%) of patients were cannabis-only positive. Overall, cannabis-alone showed the highest frequency of substance used among the currently diagnosed psychotic disorders. According to urine tests, cannabis demonstrates the higher frequency of intake in both studied groups. 66.7% of the studied population had 1–5 years self-reported histories of substance abuse predating the first psychotic episode. (4) Conclusions: The percentage of cannabis and tramadol among the first episode psychotic patients has been unexpectedly high and the standard urine testing should be considered in emergency and mental health facilities.

Abstract
The effect of race/ethnicity and religious affiliation on treatment outcomes among 107 individuals with co-occurring substance use disorder (SUD) and full or subthreshold posttraumatic stress disorder (PTSD) was examined in a secondary analysis. Participants were randomly assigned to one of three treatment conditions: dual-disorder treatment of PTSD and SUD using prolonged exposure; single-disorder relapse prevention treatment for SUD; or an active monitoring control group. Results revealed no significant interaction between race/ethnicity and treatment on PTSD and substance use frequency. However, compared to Whites, African Americans had significantly lower levels of PTSD over the course of treatment. Religious affiliation moderated the impact of treatment on substance use frequency and was a significant predictor of PTSD scores during treatment. Results highlight the need to explore factors associated with social identity variables such as race and religion that may enhance or attenuate the mechanisms of treatments for PTSD and SUD.

Proximate determinants of tuberculosis in Indigenous peoples worldwide: a systematic review. LANCET GLOBAL HEALTH 2019; 7:e68-e80. [PMID: 30554764 DOI: 10.1016/s2214-109x(18)30435-2] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/20/2017] [Revised: 08/29/2018] [Accepted: 09/05/2018] [Indexed: 01/30/2023]
Abstract
BACKGROUND Indigenous peoples worldwide carry a disproportionate tuberculosis burden. There is an increasing awareness of the effect of social determinants and proximate determinants such as alcohol use, overcrowding, type 1 and type 2 diabetes, substance misuse, HIV, food insecurity and malnutrition, and smoking on the burden of tuberculosis. We aimed to understand the potential contribution of such determinants to tuberculosis in Indigenous peoples and to document steps taken to address them. METHODS We did a systematic review using seven databases (MEDLINE, Embase, CINAHL, Global Health, BIOSIS Previews, Web of Science, and the Cochrane Library). We identified English language articles published from Jan 1, 1980, to Dec 20, 2017, reporting the prevalence of proximate determinants of tuberculosis and preventive programmes targeting these determinants in Indigenous communities worldwide. We included any randomised controlled trials, controlled studies, cohort studies, cross-sectional studies, case reports, and qualitative research. Exclusion criteria were articles in languages other than English, full text not available, population was not Indigenous, focused exclusively on children or older people, and studies that focused on pharmacological interventions. FINDINGS Of 34 255 articles identified, 475 were eligible for inclusion. Most studies confirmed a higher prevalence of proximate determinants in Indigenous communities than in the general population. Diabetes was more frequent in Indigenous communities within high-income countries versus in low-income countries. The prevalence of alcohol use was generally similar to that among non-Indigenous groups, although patterns of drinking often differed. Smoking prevalence and smokeless tobacco consumption were commonly higher in Indigenous groups than in non-Indigenous groups. Food insecurity was highly prevalent in most Indigenous communities evaluated. Substance use was more frequent in Indigenous inhabitants of high-income countries than of low-income countries, with wide variation across Indigenous communities. The literature pertaining to HIV, crowding, and housing conditions among Indigenous peoples was too scant to draw firm conclusions. Preventive programmes that are culturally appropriate targeting these determinants appear feasible, although their effectiveness is largely unproven. INTERPRETATION Indigenous peoples were generally reported to have a higher prevalence of several proximate determinants of tuberculosis than non-Indigenous peoples, with wide variation across Indigenous communities. These findings emphasise the need for community-led, culturally appropriate strategies to address smoking, food insecurity, and diabetes in Indigenous populations as important public health goals in their own right, and also to reduce the burden of tuberculosis.

Abstract
BACKGROUND Despite the high prevalence of blunt smoking among cannabis users, very few studies examine the clinical profile of blunt smokers relative to those using more common methods of cannabis use, such as joints. METHODS The current study uses baseline data from the ACCENT (Achieving Cannabis Cessation-Evaluating N-acetylcysteine Treatment) study, a multi-site randomized pharmacotherapy clinical trial within the National Drug Abuse Treatment Clinical Trials Network, to predict the association between blunt and joint use frequency and cannabis use characteristics (e.g., grams of cannabis used) and consequences (e.g., withdrawal) among past-month cannabis users (N = 377) who were screened for study participation. RESULTS After controlling for race, age, gender, other forms of cannabis use (including joint use) and nicotine dependence, multivariable linear regression models indicated that the number of days of blunt use in the past month was a significant predictor of the average amount of cannabis per using day (t = 3.04, p < .01), the estimated average cost of cannabis (t = 2.28, p < .05) and Cannabis Withdrawal Scale scores (t = 1.94, p < .05). Frequency of joint use did not significantly predict any of the cannabis use characteristics or consequences. CONCLUSIONS Blunt smokers may present to treatment with greater amounts of cannabis smoked and more intense withdrawal symptoms, which may adversely impact their likelihood of successful abstinence. Cannabis-dependent blunt smokers may be more likely to benefit from treatment that targets physiological and mood-related withdrawal symptoms.

Abstract
BACKGROUND Daily cannabis use is increasing in the United States (US). Yet, it is not known whether daily cannabis use is disproportionately common, or whether it has increased differentially over time, by mental health status. This study estimated the prevalence of daily cannabis use among adults in the US with and without past-month serious psychological distress (SPD; measured by the Kessler Psychological Distress Scale (K6)) in 2016 and estimated trends in daily cannabis use by past-30-day SPD status from 2008 to 2016. METHODS Data were drawn from adults age 18 and older in the 2008-2016 National Survey on Drug Use and Health (combined total analytic sample n = 356,413). Linear time trends of daily cannabis use, stratified by SPD status, were assessed using logistic regression models with continuous year as the predictor. RESULTS In 2016, past-month daily cannabis use was significantly more common among those with past-month SPD (8.07%), compared to those without past-month SPD (2.66%). Daily cannabis use increased significantly from 2008 to 2016 among those both with and without SPD although use among those with SPD was persistently higher than use among those without SPD over the time period studied. CONCLUSIONS Daily cannabis use is significantly more common among persons with serious psychological distress and is increasing in this group, as well as among those without. Given this increase and the high prevalence of cannabis use among those with SPD, it may be important to consider potential consequences of this increased use for those with mental health vulnerabilities.

Abstract
Background: Due to significant comorbidity and impairment associated with cannabis use and cannabis use disorder, understanding time trends in cannabis use and cannabis use disorder is an important public health priority.Objectives: To identify trends in cannabis use and cannabis use disorder overall, and by sociodemographic subgroup.Methods: Narrative review of published findings on trends in cannabis use and cannabis use disorders in data from repeated cross-sectional US general population surveys. In addition, in National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; 2002-2002) and NESARC-III (2012-2013) data, logistic regression was used to examine whether trends differed between subgroups of adults.Results: The review showed that in adults, cannabis use increased over the past decade overall and within sociodemographic subgroups (gender, age, race/ethnicity, income, education, marital status, urbanicity, region, pregnancy status, disability status), with greater increases in men and disabled adults. Most sources also indicated significant increases in cannabis use disorders. New analysis showed significantly greater increases in adult cannabis use and cannabis use disorder in men (p ≤ .0001); young adults (p < .05); Blacks (vs. Whites, p < .01); low income groups (p < .001); never-married p ≤ .0001), and urban residents (p < .05). In adolescents, cannabis use generally decreased, although recent increases were observed in older and non-White adolescents.Conclusion: Cannabis use and cannabis use disorder are increasing in adults, with specific sociodemographic groups at higher risk, and may be increasing in some adolescent subgroups. Studies should determine mechanisms for differential trends to provide information to policymakers and enable informed decisions on cannabis legalization and service planning.

Abstract
BACKGROUND Despite the status of tobacco and marijuana as two of the most commonly used substances in the U.S., both have detrimental health and social consequences for disfranchized African-Americans. Substance use may be shaped by social contextual influences from families and peers in African-American communities, and little research has examined perceptions of wrongfulness, harms, and dangers associated with daily tobacco and marijuana use among African-American women. OBJECTIVES This study explores the effects of African-American women's social context and substance use perceptions (wrongfulness/harmfulness/dangerousness) on daily tobacco and marijuana use. METHODS Survey data was collected in-person from 521 African-American women. Multivariate logistic models identified the significant correlates of women's daily use of tobacco and marijuana in the past six months. RESULTS 52.59% of participants reported daily tobacco use and 10.56% used marijuana daily. Multivariate models indicated that women were more likely to be daily tobacco users if they had a family member with a substance use problem or perceived tobacco use to be wrong, harmful, or more dangerous than marijuana. In the models with marijuana as the dependent variable, women who lived with a person who used drugs were more likely to use marijuana daily. Perceiving marijuana use as wrong or harmful to one's health was protective against daily marijuana use. CONCLUSIONS Findings stress the need for prevention and intervention efforts for African-American women that highlight social context influences and promote greater awareness of the health risks associated with daily tobacco and marijuana use.

Abstract
Although there is little difference in rates of marijuana use between White and Black youth, Blacks have significantly higher rates of marijuana use and disorder in young adulthood. Theory suggests that factors tied to social disadvantage may explain this disparity, and neighborhood setting may be a key exposure. This study sought to identify trajectories of marijuana use in an urban sample during emerging adulthood, neighborhood contexts that predict these trajectories and social role transitions or "turning points" that may redirect them. Data are from a longitudinal cohort study of 378 primarily Black emerging adults who were first sampled in childhood based on their residence in low-income neighborhoods in Baltimore City and followed up annually. Group-based trajectory modeling identified three groups: No Use (68.8%), Declining Use (19.6%), and Chronic Use (11.7%). Living in close proximity to an alcohol outlet, and living in a neighborhood with more female-headed households and higher rates of violent crime increased the odds of membership in the Chronic Use group relative to No Use. Living in a neighborhood with more positive social activity increased the odds of membership in the Declining Use group relative to No Use. Not receiving a high school diploma or GED, pregnancy, and parenting also increased the odds of membership in the Declining Use group relative to No Use. These findings provide support that minority youth living in socially toxic and disordered neighborhoods are at increased risk of continuing on a trajectory of marijuana use during emerging adulthood while positive social activity in neighborhoods has the potential to redirect these negative trajectories. Besides taking on the responsibilities of parenting, emerging adults in the marijuana user groups had similar educational and family outcomes, suggesting that early marijuana use may have long-term implications.

Abstract
Cannabinoids are the most commonly abused illicit drugs worldwide. While cannabis can be beneficial for certain heath conditions, abuse of potent synthetic cannabinoids has been on the rise. Exposure to cannabinoids is also prevalent in women of child-bearing age and pregnant women. These compounds can cross the placental barrier and directly affect the fetus. They mediate their effects primarily through G-protein coupled cannabinoid receptors, CB1 and CB2. In addition to significant neurological effects, cannabinoids can trigger robust immunomodulation by altering cytokine levels, causing apoptosis of lymphoid cells and inducing suppressor cells of the immune system. Profound effects of cannabinoids on the immune system as discussed in this review, suggest that maternal exposure during pregnancy could lead to dysregulation of innate and adaptive immune system of developing fetus and offspring potentially leading to weakening of immune defenses against infections and cancer later in life. Emerging evidence also indicates the underlying role of epigenetic mechanisms causing long-lasting impact following cannabinoid exposure in utero.

Abstract
BACKGROUND In emerging adulthood when many youth are maturing out of marijuana use, Blacks continue to have high rates of use and disorder. Theory suggests that factors tied to neighborhood disadvantage may partially explain this phenomenon but research is limited. OBJECTIVES This study examines the influence of neighborhood physical and social disorder on transitions in marijuana use during emerging adulthood in a low-income urban sample. METHODS 379 primarily Black young adults residing in low-income neighborhoods in Baltimore City were followed-up annually from ages 18 to 21. Neighborhood environment was evaluated using a valid and reliable field-rater assessment of the residential block. Longitudinal latent class and latent transition analyses were performed. RESULTS Fit indices supported three-classes of marijuana use: no use, infrequent use and frequent use. Between ages 18 and 21, young adults tended to transition toward lower levels of use. However, neighborhood physical disorder was associated with transitioning to increased marijuana use (no use to frequent use; AOR = 2.712; p = .023) while positive neighborhood social activity was associated with a decreased risk (AOR = 0.002; p = .013). Neighborhood social activity was also associated with decreases in use (frequent to infrequent use; AOR = 2.342; p = .020). Conclusions/Importance: These findings demonstrate that physical disorder within the context of a low-income urban neighborhood adversely impacts marijuana use. However, even in the presence of physical disorder, interventions that foster collective efficacy among residents through positive social activity may prevent initiation and progression of marijuana use.

Abstract
BACKGROUND This study compared young adults with and without a medical marijuana (MM) recommendation from a provider ("MM card") on their developmental trajectories of frequent marijuana use and marijuana-related problems in young adulthood. METHODS The analytic sample consists of young adult past month marijuana users (N = 671) who were part of a larger, diverse, and predominantly California cohort. Analyses are based on data from seven surveys completed from ages 13-19. RESULTS At age 19, 28% of participants reported having an MM card to legally purchase marijuana from an MM dispensary. A multiple group latent growth model indicated that young adults who had an MM card showed steeper increases in frequent marijuana use (i.e., 20-30 days of use in the past month) from ages 13-19 compared to young adults who did not have an MM card. Logistic regression models that matched MM cardholders and non-MM cardholders on individual sociodemographic characteristics found that MM cardholders were more likely to report marijuana negative consequences, selling marijuana/hashish, and driving under the influence of marijuana in the past year. In addition, MM cardholders were more likely to have tried cutting down or quitting in the past 3-months. CONCLUSIONS Among young adult marijuana users, those with an MM card had a higher risk profile for marijuana use and related problems compared to those without an MM card. Given expanding state legalization of MM, this issue warrants further attention.

Abstract
Background: Along with alcohol, cannabis is one of the most commonly used substances among women of childbearing age. Recent studies indicate detrimental effects of prenatal cannabis use. Because many women use these substances before realizing they are pregnant, these serious health consequences for women and their offspring are of great concern. Despite the recent upsurge in cannabis use, little is known about individual and sociocultural factors that may contribute to risk of a cannabis-exposed pregnancy, particularly among Latinas of child-bearing age also at risk of an alcohol-exposed pregnancy (AEP). Objectives: Examine the relationships of acculturation, alcohol use, alcohol problems, and psychological distress with frequency of cannabis use among adult Latinas at risk of an AEP. Methods: The hypothesized model included 76 Latinas and was analyzed using path analysis. The study used baseline data from a randomized controlled trial of an intervention targeting risky drinking and tobacco use among women at risk of an AEP in primary care clinics. Results: Greater acculturation was associated with more frequent cannabis use and greater psychological distress. There was a positive indirect relationship between acculturation and alcohol use and alcohol problems through psychological distress. Greater alcohol problems were associated with more frequent cannabis use. Greater psychological distress and alcohol use were indirectly related to more frequent cannabis use through alcohol problems. Conclusions: Findings underscore the critical role of acculturation and alcohol-related problems in cannabis use frequency and have relevant implications for preventive efforts addressing cannabis use among Latinas at risk of an AEP.

Abstract
BACKGROUND Alcohol, cannabis, and tobacco use are prevalent in young adults and may be differentially related to psychological symptoms characterized as externalizing or internalizing. OBJECTIVES This study examined the use of alcohol, cannabis, and various tobacco products in relation to externalizing (ADHD) versus internalizing factors (depression, anxiety), hypothesizing alcohol and cannabis use are associated with externalizing factors whereas tobacco use is related to internalizing factors. METHODS Data from a 2-year longitudinal study of 2,397 US college students (aged 18-25) launched in 2014 were analyzed. Adult ADHD Self-Report Scale, Patient Health Questionnaire-9 item (assessing depressive symptoms), and the Zung Self-Rating Anxiety Scale scores were examined in relation to subsequent past 30-day use of alcohol, cannabis, and tobacco products (cigarettes, little cigars/cigarillos, smokeless tobacco, e-cigarettes, hookah), as well as nicotine dependence per the Hooked on Nicotine Checklist. RESULTS Participants were 20.49 (SD = 1.93) years old, 64.7% female, and 65.5% White. In multivariable analyses, greater ADHD symptoms predicted alcohol and cannabis use (p = .042 and p = .019, respectively). Cigarette and little cigar/cigarillo use were predicted by greater depressive (p = .001 and p = .002, respectively), and anxiety symptoms (p = .020 and p = .027, respectively). Nicotine dependence was correlated with greater anxiety symptoms (p = .026). Counter to hypotheses, smokeless tobacco use was predicted by greater ADHD symptoms (p = .050); neither e-cigarette nor hookah use were predicted by these psychological symptoms. Conclusions/Importance: Research examining risk factors for tobacco use must distinguish among the various tobacco products. Moreover, interventions may need to differentially target use of distinct substances, including among the range of tobacco products.

Abstract
Pain and substance use are highly prevalent and co-occurring conditions that continue to garner increasing clinical and empirical interest. Although nicotine and tobacco, alcohol, and cannabis each confer acute analgesic effects, frequent or heavy use may contribute to the development and progression of chronic pain, and pain may be heightened during abstinence. Additionally, pain can be a potent motivator of substance self-administration, and it may contribute to escalating use and poorer substance-related treatment outcomes. We integrated converging lines of evidence to propose a reciprocal model in which pain and substance use are hypothesized to interact in the manner of a positive feedback loop, resulting in the exacerbation and maintenance of both conditions over time. Theoretical mechanisms in bidirectional pain-substance use relations are reviewed, including negative reinforcement, social cognitive processes, and allostatic load in overlapping neural circuitry. Finally, candidate transdiagnostic factors are identified, and we conclude with a discussion of clinical implications and future research directions.

Abstract
BACKGROUND Cannabis is the most commonly used illicit drug among U.S. adolescents and adults, but little is known about factors that drive trends in cannabis use prevalence. To better understand drivers of these trends, we aimed to estimate age, period, and cohort effects on past-month cannabis use among U.S. individuals age 12 and older from 2002 to 2015. METHODS We conducted an age-period-cohort analysis on past-month cannabis use among participants ages 12 and older using the National Survey on Drug Use and Health (NSDUH), an annual cross-sectional nationally-representative survey of drug use. Additionally, we examined how age, period, and cohort effects differed across gender. Participants (n = 779,799) self-reported cannabis patterns using a computer-assisted telephone interview (CATI). RESULTS Past-month cannabis use in this population increased from 6.0% in 2002 to 8.1% in 2015. Distinct age, period, and cohort effects were observed. Compared to participants ages 12-13, participants ages 18-21 (PR: 16.8, 95% CI: 15.6, 18.1) and 22-25 (PR: 13.2, 95% CI: 12.2, 14.4) had dramatically higher prevalence of past-month cannabis use. Compared to participants in 2002, participants in 2014 (PR: 1.2, 95% CI: 1.1, 1.4) and 2014 (PR: 1.2, 95% CI: 1.1, 1.4) had slightly higher prevalence of past-month cannabis use. Compared to the 1940s birth cohort, the 1950s birth cohort (PR: 1.8, 95% CI: 1.5, 2.2) had a higher prevalence of past-month cannabis use. CONCLUSIONS Past-month cannabis use is prevalent and increasing among U.S. adults. Distinct age, period, and cohort effects are at play, though age effects are strongest.

Abstract
OBJECTIVE This study examined the interactive role of affectivity and stress in substance use severity among ethnic minority, emerging adult males, using linguistic indicators of affect obtained through social media. METHOD Participants were 119 emerging adult, ethnic minority males (ages 18-25) who provided access to their mobile phone text messaging and Facebook activity for 6-months. Computerized text analysis (LIWC2015) was used to obtain linguistic indices of positive and negative affect from texts and Facebook posts. The Perceived Stress Scale was used to measure stress, and items from the Drug Abuse Screening Test were used to measure substance use severity. RESULTS Generalized estimating equations showed that higher negative affect in texts was associated with greater substance use severity. Stress moderated the relationship between positive affect expressed in Facebook posts and substance use such that higher positive affect in Facebook posts was associated with less substance use at higher stress and greater substance use at lower stress. CONCLUSIONS Findings highlight the complexities of interactions between stress and affectivity. Findings could inform development of substance use interventions for young males that employ social technologies.

Abstract
STUDY OBJECTIVE Pregnant and nonpregnant populations in the United States report marijuana as the most commonly used illicit drug. Patterns of marijuana use and psychosocial correlates are unclear among non-treatment-seeking teenage girls. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: The objective of this study was to use cross-sectional data to examine the psychosocial correlates of recent marijuana use among a sample of 646 pregnant and nonpregnant adolescent girls presenting to urban primary care clinics (mean age = 15.6 years, SD = 1.9 years; 65% African American; 8.8% pregnant). RESULTS In Poisson regression analysis, frequency of marijuana use was significantly associated with greater likelihood of pregnancy (incident rate ratio [IRR], 1.30; 95% CI, 1.03-1.65), alcohol use (IRR, 1.11; 95% CI, 10.08-1.14), condomless sex (IRR, 1.95; 95% CI, 1.61-2.37), parents' drug use (IRR, 1.04; 95% CI, 1.02-1.05), and negative peer influences (IRR, 1.12; 95% CI, 1.10-1.16). CONCLUSION Marijuana use among adolescent girls in this sample was associated with a number of risk behaviors as well as parental and peer influences. Culturally sensitive screening and intervention approaches for marijuana use among adolescent girls should address multiple individual, relationship, and community factors, to prevent unwanted pregnancy as well as to reduce marijuana use during this vulnerable time.

Abstract
The rates of co-occurring cannabis and tobacco use are higher among African Americans relative to other racial/ethnic groups. One plausible approach to treating co-use among African Americans is to examine the effectiveness of treatments for the sole use of cannabis and tobacco to identify effective approaches that might be combined to treat the dual use of these substances. The current meta-analysis sought to include studies that reported cannabis and/or tobacco use outcomes from randomized clinical trials (RCTs) with 100% African American samples. A total of 843 articles were considered for inclusion, 29 were reviewed by independent qualitative coders, and 22 were included in the review. There were no articles on cannabis use treatment with a 100% African American sample, resulting in a need to lower the threshold (60%) and conduct a scoping review of cannabis studies. Preliminary evidence from a small number of studies (k = 7) supports the use of Motivational Interviewing and Cognitive-Behavioral Therapy to treat cannabis use among African Americans, but not Contingency Management. Results from a meta-analysis of 15 tobacco studies found higher rates of smoking abstinence in the treatment condition relative to control conditions overall and across short and long-term follow-up periods. Significant differences in smoking abstinence were also found when examining the effects of pharmacological treatments relative to their control conditions. The clinical and research implications of these findings for future psychosocial and pharmacological trials for cannabis and tobacco use and co-use among African Americans are described.

Abstract
PURPOSE We evaluate if cigarette smoking and/or nicotine dependence predicts cannabis use disorder symptoms among adolescent and young adult cannabis users and whether the relationships differ based on frequency of cannabis use. METHODS Data were drawn from seven annual surveys of the NSDUH to include adolescents and young adults (age 12-21) who reported using cannabis at least once in the past 30 days (n = 21,928). Cannabis use frequency trends in the association between cigarette smoking, nicotine dependence and cannabis use disorder symptoms were assessed using Varying Coefficient Models (VCM's). RESULTS Over half of current cannabis users also smoked cigarettes in the past 30 days (54.7% SE 0.48). Cigarette smoking in the past 30 days was associated with earlier onset of cannabis use, more frequent cannabis use and a larger number of cannabis use disorder symptoms compared to those who did not smoke cigarettes. After statistical control for socio-demographic characteristics and other substance use behaviors, nicotine dependence but not cigarette smoking quantity or frequency was positively and significantly associated with each of the cannabis use disorder symptoms as well as the total number of cannabis symptoms endorsed. Higher nicotine dependence scores were consistently associated with the cannabis use disorder symptoms across all levels of cannabis use from 1 day used (past month) to daily cannabis use, though the relationship was strongest among infrequent cannabis users. CONCLUSION Prevention and treatment efforts should consider cigarette smoking comorbidity when addressing the increasing proportion of the US population that uses cannabis.

Abstract
OBJECTIVES The study examined sex differences in trend and clinical characteristics of cannabis use disorder (CUD) diagnosis involved hospitalizations among adult patients. METHODS We analyzed hospitalization data from the 2007-2011 Nationwide Inpatient Samples for patients aged 18-64 years (N = 15,114,930). Descriptive statistics were used to characterize demographic variables and to compare the proportions of CUD diagnosis and comorbid patterns between male and female hospitalizations. Logistic regressions were performed to examine the association of sex and other demographic variables with CUD diagnosis. RESULTS During the study period, 3.3% of male and 1.5% of female hospitalizations had any-listed CUD diagnoses, and both sexes presented an upward trend in the number, rate, and proportion of CUD diagnosis. Among hospitalizations for patients aged 18-25 years, about 1 in 10 males and 1 in 20 females included a CUD diagnosis, and this proportion decreased with age strata. Mental disorders accounted for the highest proportion of CUD involved inpatient hospitalizations, and female CUD involved hospitalizations included a higher proportion of mental disorders that required hospitalized care compared with male hospitalizations (41% vs 36%). In each sex group, younger age, black race, lower household income, large metropolitan residence, non-private insurance, substance use diagnosis, and mental disorders were associated with elevated odds of having CUD diagnosis. CONCLUSION The large sample of clinical hospitalization data suggest an increased trend in CUD diagnosis and sex differences in several comorbidities with CUD-involved hospital admissions. Prevention and treatment for CUD should consider sex differences in clinical comorbidities.

Abstract
Heavy cannabis use is associated with a wide array of physical, mental, and functional problems. Therefore, cannabis use disorders (CUDs) may be a major public health concern. Given the adverse health consequences of CUDs, the present study seeks to find possible precursors of CUDs. The current study consisted of 5 waves of data collection from the Harlem Longitudinal Development Study. Among 816 participants, about half are African Americans (52%), and the other half are Puerto Ricans (48%). We used Mplus to obtain the triple trajectories of alcohol use, tobacco use, and depressive symptoms. Logistic regression analyses were then conducted to examine the associations between the trajectory groups and CUDs. The 5 trajectory groups were (1) moderate alcohol use, high tobacco use, and high depressive symptoms (MHH; 12%); (2) moderate alcohol use, high tobacco use, and low depressive symptoms (MHL; 26%); (3) moderate alcohol use, low tobacco use, and low depressive symptoms (MLL; 18%); (4) low alcohol use, no tobacco use, and high depressive symptoms (LNH; 11%); and (5) low alcohol use, no tobacco use, and low depressive symptoms (LNL; 33%). The MHH, MHL, MLL, and LNH trajectory groups were associated with an increased likelihood of having CUDs compared to the LNL trajectory group after controlling for a number of confounding factors (e.g., CUDs in the late 20s). The findings of the current longitudinal study suggest that treatments designed to reduce or quit drinking as well as smoking and to relieve depressive symptoms may reduce the prevalence of CUDs.

Changes in Marijuana Use Across the 2012 Washington State Recreational Legalization: Is Retrospective Assessment of Use Before Legalization More Accurate? J Stud Alcohol Drugs 2018; 79:495-502. [PMID: 29885159 PMCID: PMC6005249 DOI: 10.15288/jsad.2018.79.495] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2016] [Accepted: 12/01/2017] [Indexed: 11/24/2022] Open
Abstract
OBJECTIVE The purpose of this study was to evaluate changes in marijuana use prevalence and user characteristics across the 2012 recreational legalization in Washington State. Differences in change estimates between retrospective and contemporaneous pre-legalization measures are compared and considered in relation to potential social acceptability and illegality effects on reporting. METHOD Four representative surveys of the Washington State population 18 years and older were conducted by telephone, two in 2014 and two in 2015, which are combined by year for analyses (N = 3,451). Respondents reported their current past-year use frequency and retrospective frequency of use in 2012 before the election in which legalization was passed. They also provided demographic information and details of alcohol use, including simultaneous use with marijuana. RESULTS A small and not statistically significant increase of 1.2 percentage points in past-year use prevalence, from 24.3% (22.3-26.5) to 25.6% (23.6-27.6), was found when combining the surveys. No statistically significant change was found in the prevalence of simultaneous use with alcohol, which decreased from 12.9% (11.3-14.7) to 12.6% (11.0-14.4). In contrast, estimates from the National Survey on Drug Use and Health (NSDUH) indicate substantially increased prevalence, from 15.5% (13.8-17.3) in 2010-2012 to 19.1% (16.9-21.4) in 2013-2014, although this change is not statistically significant. Other findings of interest from the Washington State surveys include new users after legalization tending to be older, White, and moderate drinkers who do not use marijuana simultaneously with alcohol. CONCLUSIONS A retrospective pre-legalization measure showed only a small increase in marijuana use prevalence in contrast to larger changes found in prospectively assessed use in the NSDUH. Changes in the social acceptability and legal status of marijuana after legalization may have increased reporting of pre-legalization use compared with concurrent assessments.

Abstract
Medical cannabis (MC) is used for a variety of conditions including chronic pain. The goal of this report was to provide an in-depth qualitative exploration of patient perspectives on the strengths and limitations of MC. Members of MC dispensaries (N = 984) in New England including two-thirds with a history of chronic pain completed an online survey. In response to "How effective is medical cannabis in treating your symptoms or conditions?," with options of 0% "no relief" to 100% "complete relief," the average was 74.6% ± 0.6. The average amount spent on MC each year was $3064.47 ± 117.60, median = $2320.23, range = $52.14 to $52,140.00. Open-ended responses were coded into themes and subthemes. Analysis of answers to "What is it that you like most about MC?" (N = 2592 responses) identified 10 themes, including health benefits (36.0% of responses, eg, "Changes perception and experience of my chronic pain."), the product (14.2%, eg, "Knowing exactly what strain you are getting"), nonhealth benefits (14.1%), general considerations (10.3%), and medications (7.1%). Responses (N = 1678) to "What is it that you like least about MC?" identified 12 themes, including money (28.4%, eg, "The cost is expensive for someone on a fixed income"), effects (21.7%, eg, "The effects on my lungs"), the view of others (11.4%), access (8.2%), and method of administration (7.1%). These findings provide a patient-centered view on the advantages (eg, efficacy in pain treatment, reduced use of other medications) and disadvantages (eg, economic and stigma) of MC.
