Gracia-Lor E, Pérez-Valenciano A, De Oro-Carretero P, Ramírez-García L, Sanz-Landaluze J, Martín-Gutiérrez MJ. Consumption of illicit drugs and benzodiazepines in six Spanish cities during different periods of the COVID-19 pandemic. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 935:173356. [PMID: 38772484 DOI: 10.1016/j.scitotenv.2024.173356] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 05/17/2024] [Accepted: 05/17/2024] [Indexed: 05/23/2024]
Abstract
Wastewater-based epidemiology (WBE) can provide objective and real time information about the use of addictive substances. A national study was conducted by measuring the most consumed illicit drugs, other drugs whose consumption is not so widespread but has increased significantly in recent years, and benzodiazepines in untreated wastewater from seven wastewater treatment plants (WWTPs) in six Spanish cities. Raw composite wastewater samples were collected from December 2020 to December 2021, a period in which the Spanish and regional governments adopted different restriction measures to contain the spread of the COVID-19 pandemic. Samples were analyzed using a validated analytical methodology for the simultaneous determination of 18 substances, based on solid-phase extraction and liquid-chromatography tandem mass spectrometry. Except for heroin, fentanyl, 6-acetylmorphine and alprazolam, all the compounds were found in at least one city and 9 out of 18 compounds were found in all the samples. In general, the consumption of illicit drugs was particularly high in one of the cities monitored in December 2020, when the restrictions were more severe, especially for cannabis and cocaine with values up to 46 and 6.9 g/day/1000 inhabitants (g/day/1000 inh), respectively. The consumption of MDMA, methamphetamine and mephedrone was notably higher in June 2021, after the end of the state of alarm, in the biggest population investigated in this study. Regarding the use of benzodiazepines, the highest mass loads corresponded to lorazepam. This study demonstrates that WBE is suitable for complementing epidemiological studies about the prevalence of illicit drugs and benzodiazepines during the COVID-19 pandemic restrictions.

Abstract
Abstract
This study examined cannabis use motives in individuals with anxiety disorders and compared motives between infrequent and frequent cannabis users. It was hypothesised that coping motives would be endorsed at a significantly higher rate than other motives, and that frequent cannabis users would endorse coping motives significantly more than infrequent users. Participants were 144 adults seeking clinical services for anxiety disorders who reported using cannabis. Cannabis use was categorized by infrequent (n = 54) and frequent (n = 90) use. Anxiety symptoms were assessed and deemed clinically significant. Participants completed measures of cannabis use motives, cannabis use patterns, and cannabis use disorder symptoms, cross-sectionally. Cannabis use motives were examined for the entire sample and compared between frequent and infrequent users. In general, cannabis users endorsed coping (i.e., use for managing distress) and enhancement (i.e., use for fun, pleasant feeling, or the high) motives at equal rates (p = .265) and more than other motives (p < .001). Frequent users reported using cannabis for coping and expansion motives (i.e., use to change one's thinking) significantly more than infrequent users. These results indicate that individuals with anxiety disorders use cannabis for various reasons, some of which may not be directly related to their mental health symptoms. Future research is needed to compare motives for cannabis use in those with anxiety disorders, other mental health populations, and the general population, as well as examine motives for cannabis use within specific anxiety disorders.

Drug Alcohol Depend 2022; 240:109623.

Abstract
BACKGROUND Given recent changes in the legal status of cannabis, the risks and benefits associated with its use have become an important public health topic. A growing body of research has demonstrated that posttraumatic stress disorder (PTSD) and recreational cannabis use (RCU) frequently co-occur, yet findings are inconsistent (e.g., direction of effect) and methodological variability makes comparison across studies difficult. METHODS We conducted a comprehensive systematic review of all studies (N = 45) published before May 2020 regarding etiologic models of co-occurring RCU and PTSD, as well as provided a methodological critique to inform suggestions for future research initiatives. RESULTS Findings indicate that a majority of studies (n = 37) demonstrated a significant association between RCU and PTSD. Findings provide evidence for the self-medication and high-risk models posited to explain co-occurring RCU and PTSD despite variability in assessment of RCU, which includes commonly used non-standardized self-report questions. CONCLUSION The association between RCU and PTSD is likely bidirectional. Results inform clinicians and researchers working in the mental health and cannabis use fields how the variability in findings on the association between RCU and PTSD may be attributable, in part, to methodological issues that permeate the extant literature pertaining to RCU and PTSD.

Abstract
Simultaneous alcohol and marijuana (SAM) use is common, but it exacerbates negative consequences. Individuals use alcohol and cannabis products in different ways and have distinct reasons for use. The present study examines day-level effects of motives on consequences on SAM-use days, accounting for consumption, and tests whether using multiple alcohol (e.g., beer + liquor) and/or cannabis (e.g., concentrate + leaf) products on the same day mediates these relations. College students engaging in SAM use at least once in the past month (N = 281; Mage = 20.17) completed two bursts of 28 consecutive days of data collection. We examined within-person effects of motives (effect-enhancement, social, offered [it was offered], coping) on number of negative consequences and on experiencing hangover, nausea, or blackout; and indirect effects via two concurrent mediators: using multiple alcohol products and multiple cannabis products. Total effect models showed effect-enhancement motives were related to nausea, social motives to number of total consequences and hangover, and coping motives to blackout. Effect-enhancement, social, and offered motives evinced significant indirect effects on consequence outcomes via multiple alcohol, but not cannabis, product use. Coping motives did not exhibit significant indirect effects, and were related to multiple cannabis, but not alcohol, product use, although all other motives were related to both mediators. Findings support recent work demonstrating within-person relations between social motives and negative consequences on SAM-use days. Limiting the number of alcohol products consumed on SAM-use days may be beneficial, particularly for young adults using to enhance intoxication or for social reasons.

Abstract
We investigated profiles of cannabis use motives among current cannabis-consuming college students. Then we assessed profile differences in demographic characteristics, social contexts of use, regulatory environment, alcohol use, negative affect, negative consequences, and cannabis use. Participants ( N = 1, 213) were from three universities in states with different cannabis legislation. Six profiles emerged: Low Motives, Low to Moderate Enhance, High Enhance, High Enhance & Social + Moderate Expand, High Enhance & Cope, and High Motives. Profiles differed in social contexts of use, sex, alcohol use, negative affect, and regulatory environment. Profiles endorsing high and multiple motives had higher cannabis use and negative consequences, relative to profiles with low or fewer motives. Profiles characterized by high avoidance motives (i.e., coping) had the highest cannabis use and consequences. Interventions targeting types and intensity of motives for cannabis-use may help reduce use and related consequences among college students who use cannabis.

Abstract
Aunque el consumo de marihuana es altamente prevalente entre universitarios de Argentina, poco se sabe respecto a los factores que permiten distinguir a los consumidores frecuentes de marihuana de quienes consumen esporádicamente. Por esta razón, en el presente trabajo se indagó sobre las posibles variaciones en los contextos de consumo, motivos de consumo, normas percibidas y estrategias conductuales de protección entre universitarios con consumo frecuente o esporádico de marihuana, y se analizó la utilidad de este conjunto de variables para distinguir entre estos los tipos de consumidores mencionados. Para ello, se contó con una muestra de 1083 estudiantes universitarios argentinos que completó una encuesta en línea sobre el consumo de sustancias. En particular, este trabajo se realizó con la submuestra que reportó consumir marihuana en los últimos 30 días (n = 158; 51.3 % mujeres). Dicha encuesta interrogaba sobre el consumo de marihuana y las consecuencias negativas asociadas, así como por motivos de consumo, normas sociales percibidas y estrategias conductuales de protección. Como resultado, los consumidores frecuentes presentaron mayor cantidad de consecuencias negativas (M = 4.92) que los consumidores esporádicos (M = 1.82; p ≤ .05), y se halló un perfil distintivo en un conjunto de variables. A nivel multivariado, los motivos de animación (or = 1.230; p ≤ .05), las estrategias conductuales de protección (or = .941; p ≤ .05), el consumo en solitario (or = 2.024; p ≤ .05) y el consumo en fiestas universitarias (or = 2.669; p ≤ .05) discriminaron significativamente entre ambas clases de consumidores. En general, los hallazgos revelaron subpoblaciones heterogéneas de consumidores de marihuana que difieren no solo en el consumo y sus consecuencias, sino también en los contextos de consumo y en un conjunto de variables relevantes. Estas subpoblaciones distintivas requieren de intervenciones diferentes y específicas.

Abstract
BACKGROUND This study examined social and situational context predictors of prescription drug misuse among college-students at a large public university in the Midwest. Social and situational context predictors considered were hour of the day, weekend vs weekday, whether participants were at home or another place, and who they were with during instances of misuse. Salient social events, including home football games, city-regulated parties, and the 2019 Midwest polar vortex were also recorded. METHOD Using ecological momentary assessment methodology, 297 students completed momentary reports for 28 days. Participants indicated whether they had misused prescription medication (sedatives or sleeping pills, tranquilizers or anxiety medications, stimulants, and pain relievers) and reported on their social and situational context in the moment of misuse. RESULTS Multilevel modeling indicated that participants were more likely to misuse prescription medication earlier in the day vs. the evening, on weekdays vs. weekends, when at home vs. not at home, and while alone vs. with others. CONCLUSIONS This study provides descriptive information on the social context in which prescription drug misuse is most likely to occur among college students. Our findings suggest that social and situational contexts of prescription drug misuse likely differ as compared to other substances (e.g., alcohol) among college students. Further research aimed at identifying momentary predictors of prescription drug misuse in this population is warranted.

Abstract
OBJECTIVE Given the adverse outcomes associated with simultaneous alcohol and marijuana (SAM) use, understanding factors that give rise to occasions of simultaneous use is critical. This study examines the relationships between situational motives and contexts and three situational outcomes: simultaneous alcohol and marijuana use (SAM) use versus cannabis-only use, number of cannabis uses, and subjective effects. METHOD Past-month SAM users (n = 341; 52% female; 75% White; 10% Latinx/Hispanic; age 18-24) from three U.S. college campuses completed 8 weeks of surveys up to five times a day. Three-level generalized linear mixed-effects models tested the effects of situational motives and social and physical contexts on occasion type (SAM vs. cannabis-only), cannabis use, and subjective effects. RESULTS Situational social and enhancement motives were related to greater odds of SAM relative to cannabis-only use; expansion motives were reported more often on cannabis-only occasions. Using with others and at friends' places, being with others consuming cannabis, and being with others who are intoxicated were more likely when combining alcohol with cannabis. Increased number of cannabis uses and subjective effects in a social context were evident only on cannabis-only occasions. Using alone and using at home were greater on cannabis-only occasions and were associated with lower cannabis use and subjective effects. CONCLUSIONS The combination of alcohol and cannabis use occurs during social situations and when motivated by positive reinforcement but number of cannabis uses is not increased when consuming cannabis with alcohol in social situations. Characterizing the complex interplay of situational factors that contribute to risky use will inform interventions. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Do schizotypy features predict cannabis problems in partnered community adults? Addict Behav 2021; 116:106819.

Abstract
Schizotypy and its associated features-negative schizotypy, disorganization, and positive schizotypy-are correlated with increased cannabis use. Yet, it is unclear whether cannabis users with schizotypy are at greater risk of developing cannabis problems. Individuals with elevated schizotypy may be particularly vulnerable to cannabis problems. It is important to understand this association given the unknown harms of chronic cannabis use. Data for these analyses were drawn from a larger investigation of cannabis use in adult romantic relationships. Participants were community adults (N = 366; M Age = 24.6, SD = 3.1) who reported regular use of cannabis. Participants completed baseline surveys measuring cannabis use frequency, problems, and schizotypy. Follow-up assessments of cannabis problems and frequency were completed 4-, 7- and 10-months post-baseline. Multiple regression was used to test the effect of schizotypy-measured using the Schizotypal Personality Questionnaire-Brief (SPQ-B, Raine & Benishay, 1995)-on cannabis use problems controlling for 30-day cannabis use. At baseline, disorganization and positive schizotypy were associated with cannabis use, primarily for women. Results revealed that with cannabis use frequency in the model, the Disorganization subscale of the SPQ-B predicted cannabis problems at baseline and all 3 follow-up assessments. Results are consistent with research suggesting that those exhibiting odd behaviors report more problematic cannabis use. Future research may further this line of inquiry with a focus on longitudinal, reciprocal relationships among schizotypy features, cannabis use, and cannabis problems.

Abstract
This study employed taxometric procedures to replicate a previous report of the dimensional structure of problems related to cannabis consumption. Method: Over 4,000 cannabis users completed an assessment of psychological, social, occupational, and physical harms (the Marijuana Problems Scale). Three taxometric procedures (MAMBAC, MAXEIG, and L-Mode) compared the current data to simulations with a base rate of problematic cannabis use derived from representative, large-scale data estimates. Results: All three procedures confirmed the continuous, dimensional nature of these cannabis problems and suggested no underlying taxon or category. Conclusions: Psychopathological disorders, including some substance use problems, have fit categorical models suggesting that they differ in kind (rather than intensity) from the behavior of the rest of the population. Cannabis problems, however, appeared to lie along a continuum with other forms of use. Given heightened awareness for the necessity of replication and a changing legal landscape for cannabis, a second look at the dimensionality of these problems seemed warranted. New data with a larger sample and different indices of problematic use confirmed the dimensionality of cannabis problems. This replication can inform predictions about the etiology, prevention, and treatment of cannabis use disorder. Researchers should expect cannabis problems to range along a continuum without categorical distinctions. Dividing users into groups of problematic and non-problematic users likely sacrifices meaningful variance. Harm reduction strategies likely can benefit all users rather than a targeted taxon with troubles. In addition, interventions will likely progress by small, incremental steps rather than dramatic, categorical jumps in progress.

Abstract
Objective: Attention-deficit/hyperactivity disorder (ADHD) is linked prospectively to cannabis; however, no study has examined mechanisms underlying this comorbidity. We examined 5 cannabis motives (i.e., coping with negative affect, sleep, social anxiety, perceived low risk of cannabis, and altered perception) as mediators of the prospective ADHD-cannabis relation. Method: Veterans reporting lifetime cannabis use (N = 361; 93% male; 80% White) completed three semiannual assessments. Prospective mediation models using structural equation modeling analyzed the indirect effects of baseline ADHD symptoms on 12-month cannabis use and problems via each motive at 6 months. Zero-inflated negative binomial models were employed for both manifest outcomes and ADHD symptoms and motives were each modeled as 1-factor latent variables. Results: Sleep motives was a robust mediator for cannabis use frequency in single mediator models and was marginally significant when examined simultaneously with other motives after accounting for baseline cannabis use, demographics, other substance use, and other psychopathology. Coping with negative affect was the only significant mediator of ADHD symptoms and subsequent cannabis problem severity. Conclusion: Among veterans with ADHD symptoms, sleep disturbance is a salient motive for cannabis use, whereas coping with negative affect is a proximal predictor of cannabis problems. Findings support addressing sleep disturbance in adults with ADHD symptoms and converge with extant literature demonstrating robust associations between coping motives and substance use problems.

Abstract
BACKGROUND Little is known about how cannabis knowledge and attitudes impact cannabis use behavior. OBJECTIVE To test the knowledge-attitudes-behavior paradigm in active adult athletes. DESIGN The Athlete Pain, Exercise, and Cannabis Experience (PEACE) Survey, a cross-sectional survey study, used social media and email blasts to recruit participants and SurveyGizmo to collect data. PARTICIPANTS Self-defined active adult athletes (n = 1161). MAIN MEASURES Knowledge about cannabis was evaluated with four questions. Attitudes toward cannabis was evaluated with 11 questions. The attitudes questions were used in a TwoStep Cluster analysis in SPSS to assign group membership by attitudes. Chi-square was used to determine if there were differences in cluster membership by demographic factors and if knowledge about cannabis differed by cluster membership. Regression analysis was performed to determine if cannabis attitudes mediated the relationship between cannabis knowledge and cannabis use. KEY RESULTS A three-cluster solution was the best fit to the data. The clusters were named Conservative (n = 374, 32.2%), Unsure (n = 533, 45.9%), and Liberal (n = 254, 21.9). There was a significant difference among the clusters for all 11 attitudes items (all p < 0.001). Attitude cluster membership was significantly different by age (p < 0.001), primary sport (p < 0.05), and knowledge about cannabis (p < 0.001). Athletes in the liberal cluster answered the knowledge questions correctly most often. Attitudes mediated the relationship between cannabis knowledge and cannabis use [Never (32.4%), Past (41.6%), Current (26.0%)] with athletes in the liberal cluster showing more knowledge and greater likelihood to be a current cannabis user (p < 0.001). Among current cannabis users there were differential patterns of cannabis use depending on their attitudes and knowledge; liberal athletes tended to co-use THC and CBD and used cannabis longer. (p < 0.001). CONCLUSIONS Cannabis education needs to consider attitudes about cannabis, especially among those who might benefit from medical cannabis.

Abstract
Background and Objectives: Individuals with elevated social anxiety are thought to be at high risk for developing cannabis-related problems because they use cannabis to cope with anxiety-provoking social situations. Social anxiety is unique among the anxiety conditions in that it is characterized by both elevated negative affect (NA) and lower positive affect (PA). Yet it is unclear whether persons with elevated social anxiety use cannabis to decrease their NA or to increase their PA. Methods: This study examined the role of PA and NA (including cannabis use to increase PA and to decrease NA in social situations) on cannabis use frequency and related problems among current (past three-month) cannabis users (N = 278). Results: Social anxiety was significantly correlated with NA, PA, cannabis use to decrease NA, and use to increase PA. Serial mediation analyses tested the paths between social anxiety, affect, use to manage affect, typical cannabis use frequency, and cannabis use-related problems. Contrary to prediction, social anxiety was not indirectly related to use frequency or related problems via NA or PA generally. Rather, social anxiety was indirectly related to cannabis problems via the serial effect of use to cope with NA and typical use frequency and via the serial effect of use to increase PA and typical use frequency. Conclusions/Importance: Social anxiety may be associated with using cannabis to decrease NA and increase PA specifically in social situations, which increases cannabis use frequency and thus, problem risk.
