Well-being, problematic alcohol consumption and acute subjective drug effects in past-year ayahuasca users: a large, international, self-selecting online survey. Sci Rep 2017; 7:15201. [PMID: 29123145 PMCID: PMC5680239 DOI: 10.1038/s41598-017-14700-6] [Citation(s) in RCA: 43] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2017] [Accepted: 10/11/2017] [Indexed: 11/21/2022] Open
Abstract
Ayahuasca is a natural psychedelic brew, which contains dimethyltryptamine (DMT). Its potential as a psychiatric medicine has recently been demonstrated and its non-medical use around the world appears to be growing. We aimed to investigate well-being and problematic alcohol use in ayahuasca users, and ayahuasca’s subjective effects. An online, self-selecting, global survey examining patterns of drug use was conducted in 2015 and 2016 (n = 96,901). Questions were asked about: use of ayahuasca, lysergic acid diethylamide (LSD) and magic mushrooms; demographics, current well-being and past-year problematic alcohol use of past-year ayahuasca users and comparison drug users; and subjective effects of ayahuasca and comparison drugs. Ayahuasca users (n = 527) reported greater well-being than both classic psychedelic users (n = 18,138) and non-psychedelic drug-using respondents (n = 78,236). Ayahuasca users reported less problematic drinking than classic psychedelic users, although both groups reported greater problematic drinking than the other respondents. Ayahuasca’s acute subjective effects usually lasted for six hours and were most strongly felt one hour after consumption. Within our online, self-selecting survey, ayahuasca users reported better well-being than comparison groups and less problematic drinking than classic psychedelic users. Future longitudinal studies of international samples and randomised controlled trials are needed to dissect the effects of ayahuasca on these outcomes.

Moan IS, Storvoll EE, Lund IO. Worries about others' substance use-Differences between alcohol, cigarettes and illegal drugs? THE INTERNATIONAL JOURNAL OF DRUG POLICY 2017; 48:108-114. [PMID: 28822298 DOI: 10.1016/j.drugpo.2017.07.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2016] [Revised: 07/03/2017] [Accepted: 07/10/2017] [Indexed: 11/25/2022]
Abstract
BACKGROUND While it is well documented that many experience harm from others' substance use, little is known about the psychological strain associated with others' use. The aims were: (1) to describe the prevalence of worries about others' alcohol, cigarette and illegal drug use, (2) whose substance use people worry about, (3) the overlap in worries, and (4) to examine how worries about others' use of each substance vary according to demographics, own substance use and experience of harm from others' use. METHODS A population survey was conducted among 16-64year old Norwegians (N=1667). Respondents' reported on worries about others' alcohol, cigarette and illegal drug use, measures of experiences of harm from others' use of the three substances, and own substance use. RESULTS Worries about others' drinking were most prevalent. Among those who worried, others' cigarette and illegal drug use caused more frequent worry. While worry about cigarette use was mostly associated with family members' use, worry about others' alcohol and illegal drug use more often concerned friends'/acquaintances' use. About half worried about others' use of at least one substance. Across all three substances, experience of harm from others' substance use was most strongly related to worries. CONCLUSION Worries about others' substance use are common and reflect the prevalence of use of the substances in the population. In sum, the findings suggest that worry about others' alcohol and illegal drug use is primarily related to acute harm while worry about others' cigarette smoking is more related to chronic harm.

Abstract
Aims New trends in drug consumption reveal increasing polydrug use. Epidemiological indicators in the current use are based on the prevalence and the associated potential harm of a single “main” substance. We propose new indicators to evaluate frequency and potential harm of polydrug use. The indicators are used to compare drug use among countries based on survey data on adolescents' substance use in 38 European countries. Methods The approach is based on analysis of the frequency of use in the various population samples: lifetime use, twelve months use or last thirty days, depending on available data, and on the risk of harm for the substances used. Two indicators are provided: the frequency of use score (FUS) by summing the frequency of use of each substance, and the polydrug use score (PDS) that weight all the substances used by their risk. Results The indicators FUS and PDS were calculated and the distribution functions were used to characterise substance use across ESPAD countries. The analysis shows important differences in poly-substance use severity among countries presenting similar prevention policies. Conclusions Systematic analysis of substance use and the related risk are of paramount interest. The proposed indicators are designed to better monitor and understand consequences of polydrug use and to measure the resulting risk at country or population level. The indicators may also be used to assess the effects of policy interventions.

Abstract
In 2013, illegal drug use was responsible for 1.8% of years of life lost in the European Union, alcohol was responsible for 8.2% and tobacco for 18.2%, imposing economic burdens in excess of 2.5% of GDP. No single European country has optimal governance structures for reducing the harm done by nicotine, illegal drugs and alcohol, and existing ones are poorly designed, fragmented, and sometimes cause harm. Reporting the main science and policy conclusions of a transdisciplinary five-year analysis of the place of addictions in Europe, researchers from 67 scientific institutions addressed these problems by reframing an understanding of addictions. A new paradigm needs to account for evolutionary evidence which suggests that humans are biologically predisposed to seek out drugs, and that, today, individuals face availability of high drug doses, consequently increasing the risk of harm. New definitions need to acknowledge that the defining element of addictive drugs is 'heavy use over time', a concept that could replace the diagnostic artefact captured by the clinical term 'substance use disorder', thus opening the door for new substances to be considered such as sugar. Tools of quantitative risk assessment that recognize drugs as toxins could be further deployed to assess regulatory approaches to reducing harm. Re-designed governance of drugs requires embedding policy within a comprehensive societal well-being frame that encompasses a range of domains of well-being, including quality of life, material living conditions and sustainability over time; such a frame adds arguments to the inappropriateness of policies that criminalize individuals for using drugs and that continue to categorize certain drugs as illegal. A health footprint, modelled on the carbon footprint, and using quantitative measures such as years of life lost due to death or disability, could serve as the accountability tool that apportions responsibility for who and what causes drug-related harm.

Abstract
Quantitative measurement of drug consumption biomarkers in wastewater can provide objective information on community drug use patterns and trends. This study presents the measurement of alcohol consumption in 20 cities across 11 countries through the use of wastewater-based epidemiology (WBE), and reports the application of these data for the risk assessment of alcohol on a population scale using the margin of exposure (MOE) approach. Raw 24-h composite wastewater samples were collected over a one-week period from 20 cities following a common protocol. For each sample a specific and stable alcohol consumption biomarker, ethyl sulfate (EtS) was determined by liquid chromatography coupled to tandem mass spectrometry. The EtS concentrations were used for estimation of per capita alcohol consumption in each city, which was further compared with international reports and applied for risk assessment by MOE. The average per capita consumption in 20 cities ranged between 6.4 and 44.3L/day/1000 inhabitants. An increase in alcohol consumption during the weekend occurred in all cities, however the level of this increase was found to differ. In contrast to conventional data (sales statistics and interviews), WBE revealed geographical differences in the level and pattern of actual alcohol consumption at an inter-city level. All the sampled cities were in the "high risk" category (MOE<10) and the average MOE for the whole population studied was 2.5. These results allowed direct comparisons of alcohol consumption levels, patterns and risks among the cities. This study shows that WBE can provide timely and complementary information on alcohol use and alcohol associated risks in terms of exposure at the community level.

Abstract
This article provides an overview of the history of substance use and misuse and chronicles the long shared history humans have had with psychoactive substances, including alcohol. The practical and personal functions of substances and the prevailing views of society towards substance users are described for selected historical periods and within certain cultural contexts. This article portrays how the changing historical and cultural milieu influences the prevailing medical, moral, and legal conceptualizations of substance use as reflected both in popular opinion and the consensus of the scientific community and represented by the American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM). Finally, this article discusses the efforts to classify substance use disorders (SUDs) and associated psychopathology in the APA compendium. Controversies both lingering and resolved in the field are discussed, and implications for the future of SUD diagnoses are identified.

Abstract
OBJECTIVES To describe drug use, types of drugs and related factors among money boys in Hunan Province, China. STUDY DESIGN A cross-sectional study was conducted between July 2012 and January 2013. METHODS Based on respondent-driven sampling, researchers located seven 'seeds' via a gay-dating website: http://www.ixxqy.org. After three waves of recruitment, 234 money boys were enrolled. They were asked to complete a 23-item questionnaire regarding demographic characteristics, drug use, a history of human immunodeficiency virus infection and family environment. Descriptive statistics and logistic regression analysis were conducted using Statistical Package for the Social Sciences Version 20.0. RESULTS In total, 205 valid questionnaires were collected. Based on the data collected, 80 (39.0%) money boys had used drugs within the last 3 months. Rush popper (36.6%) and methamphetamine (12.7%) were used most commonly, and other drugs used were ecstasy (7.8%), ketamine (5.9%), marijuana (2.4%), morphine (1.5%), heroin (1.0%) and cocaine (0.5%). Factors included in the logistic regression were length of service (odds ratio [OR] 0.395, 95% confidence interval [CI] 0.175-0.896), being an only child (OR 2.272, 95% CI 1.108-4.659), relationship between parents (OR 0.428, 95% CI 0.213-0.858) and social network (OR 2.387, 95% CI 1.144-4.970). A shorter length of service and a good relationship between parents were protective factors against drug use, while being an only child and having a wide social network were risk factors. CONCLUSION Drug use is common among money boys. This study found that length of service, being an only child, relationship between parents and social network are associated with drug use.

Abstract
With the increasing legalization of cannabis, understanding the consequences of cannabis use is particularly timely. We examined the association between cannabis use and dependence, prospectively assessed between ages 18-38, and economic and social problems at age 38. We studied participants in the Dunedin Longitudinal Study, a cohort (n=1,037) followed from birth to age 38. Study members with regular cannabis use and persistent dependence experienced downward socioeconomic mobility, more financial difficulties, workplace problems, and relationship conflict in early midlife. Cannabis dependence was not linked to traffic-related convictions. Associations were not explained by socioeconomic adversity, childhood psychopathology, achievement orientation, or family structure; cannabis-related criminal convictions; early onset of cannabis dependence; or comorbid substance dependence. Cannabis dependence was associated with more financial difficulties than alcohol dependence; no difference was found in risks for other economic or social problems. Cannabis dependence is not associated with fewer harmful economic and social problems than alcohol dependence.

Abstract
The multifaceted gut‐brain peptide ghrelin and its receptor (GHSR‐1a) are implicated in mechanisms regulating not only the energy balance but also the reward circuitry. In our pre‐clinical models, we have shown that ghrelin increases whereas GHSR‐1a antagonists decrease alcohol consumption and the motivation to consume alcohol in rodents. Moreover, ghrelin signaling is required for the rewarding properties of addictive drugs including alcohol and nicotine in rodents. Given the hereditary component underlying addictive behaviors and disorders, we sought to investigate whether single nucleotide polymorphisms (SNPs) located in the pre‐proghrelin gene (GHRL) and GHSR‐1a gene (GHSR) are associated with alcohol use, measured by the alcohol use disorders identification test (AUDIT) and smoking. Two SNPs located in GHRL, rs4684677 (Gln90Leu) and rs696217 (Leu72Met), and one in GHSR, rs2948694, were genotyped in a subset (n = 4161) of a Finnish population‐based cohort, the Genetics of Sexuality and Aggression project. The effect of these SNPs on AUDIT scores and smoking was investigated using linear and logistic regressions, respectively. We found that the minor allele of the rs2948694 SNP was nominally associated with higher AUDIT scores (P = 0.0204, recessive model) and smoking (P = 0.0002, dominant model). Furthermore, post hoc analyses showed that this risk allele was also associated with increased likelihood of having high level of alcohol problems as determined by AUDIT scores ≥ 16 (P = 0.0043, recessive model). These convergent findings lend further support for the hypothesized involvement of ghrelin signaling in addictive disorders.

Abstract
I performed 14 person-centered ethnographies with methamphetamine-using HIV-positive men who have sex with men in San Diego, California, who were all subjects of the "anti-meth apparatus," a collection of government and nongovernment organizations focused on meth use and its sequelae. The apparatus attempts to coerce addicts to develop and perform certain identities and emotions, though addicts are capable of both passive acceptance and active disruption. In my research, those who failed to become the apparatus's ideal subject felt shame, while those who succeeded expressed pride. Those hovering in the middle experienced a perpetual struggle to become normal and rarely, if ever, succeeded. [addiction, HIV/AIDS, subjectivity].

Abstract
A panel of nine experts applied multi-criteria decision analysis (MCDA) to determine the relative overall harm to users and harms to others of street heroin (injected and smoked) and eleven non-medically used prescription opioids. The experts assessed harm scores for each of the 13 opioids on each of 20 harm criteria, weighted the criteria and explored the resulting weighted harm scores for each opioid. Both forms of heroin scored very high: overall harm score of 99 for injected heroin and 72 for smoked heroin on a scale of 0-100. The main feature that distinguishes both forms of street heroin use is that their harm to others is more than five times that of the other eleven opioids. The overall harm score of fentanyl (including injection of fentanyl extracted from patches) and diamorphine (medically prescribed form of heroin) was 54 and 51, respectively, whereas that of orally used opioids ranged from 32 (pethidine) to 11 (codeine-containing pharmaceuticals). Injected street heroin, fentanyl and diamorphine emerged as most harmful to users, with the latter two very low in harm to others. Pethidine, methadone, morphine and oxycodone are also low in harm to others, while moderate in harm to users. We conclude that the overall harms of non-medically used prescription opioids are less than half that of injected street heroin. These data may give a basis for precautionary regulatory measures that should be considered if the rising trend in non-medical use of prescription opioids were to become evident in the UK.

Abstract
BACKGROUND The present paper describes the results of a rating study performed by a group of European Union (EU) drug experts using the multi-criteria decision analysis model for evaluating drug harms. METHODS Forty drug experts from throughout the EU scored 20 drugs on 16 harm criteria. The expert group also assessed criteria weights that would apply, on average, across the EU. Weighted averages of the scores provided a single, overall weighted harm score (range: 0-100) for each drug. RESULTS Alcohol, heroin and crack emerged as the most harmful drugs (overall weighted harm score 72, 55 and 50, respectively). The remaining drugs had an overall weighted harm score of 38 or less, making them much less harmful than alcohol. The overall weighted harm scores of the EU experts correlated well with those previously given by the UK panel. CONCLUSION The outcome of this study shows that the previous national rankings based on the relative harms of different drugs are endorsed throughout the EU. The results indicates that EU and national drug policy measures should focus on drugs with the highest overall harm, including alcohol and tobacco, whereas drugs such as cannabis and ecstasy should be given lower priority including a lower legal classification.

Abstract
BACKGROUND Recent studies have challenged the idea that illegal substances are necessarily associated with more harm than those that are legal. This study investigates perceived drug harm among students at the University of Oslo (UO) and at a smaller university located on Norway's coast in a more conservative and religious region, called 'Coastal University' (CU). METHODS This study consisted of surveys (n=458) about perceived physical harm, mental health conditions, dependence, injuries and social consequences that may be associated with the use of tobacco, alcohol and cannabis. Information about substance use was also collected. Analyses of variance and multiple regression analyses were used to examine whether harm ratings differed for different drugs, whether drug type, gender and university site interacted in predicting harm ratings, and what role the participants' own substance use played in their harm ratings. RESULTS UO students rated cannabis as overall less harmful than alcohol, while the opposite was true for CU students. Tobacco received the highest physical harm score. Alcohol was rated as most harmful with regard to injuries; cannabis was rated as most harmful with regard to mental health consequences. Use of the substance in question was associated with a reduced harm rating. This was particularly true for cannabis. CONCLUSIONS Norwegian students rate the harm of substances differently from previous reports from the Norwegian general population. Most importantly, their relative ratings of cannabis harm were lower. However, the pattern was most evident among students from the urban Oslo area.

Abstract
A recent large population study of 130,000 adults in the United States failed to find evidence for a link between psychedelic use (lysergic acid diethylamide, psilocybin or mescaline) and mental health problems. Using a new data set consisting of 135,095 randomly selected United States adults, including 19,299 psychedelic users, we examine the associations between psychedelic use and mental health. After adjusting for sociodemographics, other drug use and childhood depression, we found no significant associations between lifetime use of psychedelics and increased likelihood of past year serious psychological distress, mental health treatment, suicidal thoughts, suicidal plans and suicide attempt, depression and anxiety. We failed to find evidence that psychedelic use is an independent risk factor for mental health problems. Psychedelics are not known to harm the brain or other body organs or to cause addiction or compulsive use; serious adverse events involving psychedelics are extremely rare. Overall, it is difficult to see how prohibition of psychedelics can be justified as a public health measure.

Abstract
A comparative risk assessment of drugs including alcohol and tobacco using the margin of exposure (MOE) approach was conducted. The MOE is defined as ratio between toxicological threshold (benchmark dose) and estimated human intake. Median lethal dose values from animal experiments were used to derive the benchmark dose. The human intake was calculated for individual scenarios and population-based scenarios. The MOE was calculated using probabilistic Monte Carlo simulations. The benchmark dose values ranged from 2 mg/kg bodyweight for heroin to 531 mg/kg bodyweight for alcohol (ethanol). For individual exposure the four substances alcohol, nicotine, cocaine and heroin fall into the "high risk" category with MOE < 10, the rest of the compounds except THC fall into the "risk" category with MOE < 100. On a population scale, only alcohol would fall into the "high risk" category, and cigarette smoking would fall into the "risk" category, while all other agents (opiates, cocaine, amphetamine-type stimulants, ecstasy, and benzodiazepines) had MOEs > 100, and cannabis had a MOE > 10,000. The toxicological MOE approach validates epidemiological and social science-based drug ranking approaches especially in regard to the positions of alcohol and tobacco (high risk) and cannabis (low risk).

Abstract
OBJECTIVES There is debate about whether marijuana (cannabis) use is more dangerous than alcohol use. Although difficult to make objective comparisons, research is needed to compare relative dangers in order to help inform preventive efforts and policy. METHODS Data were analyzed from a nationally representative sample of high school seniors in the Monitoring the Future study (2007-2011; Weighted n = 7437; modal age: 18) who reported lifetime use of alcohol or marijuana. Students were asked to indicate whether they experienced various adverse psychosocial outcomes resulting from use of each substance. We examined which outcomes were more prevalent for each substance. RESULTS Compared to alcohol use, marijuana use was more commonly reported to compromise relationships with teachers or supervisors, result in less energy or interest, and result in lower school or job performance. Compared to marijuana use, alcohol was more commonly reported to compromise relationships with friends and significant others; it was also reported to lead to more regret (particularly among females), and driving unsafely. Marijuana users were more likely to report no adverse outcomes. Females and white students were more likely to report various adverse outcomes and higher frequency use of each substance also increased occurrences of reported adverse outcomes. CONCLUSIONS Marijuana and alcohol are associated with unique adverse psychosocial outcomes. Outcomes differ by sex and race/ethnicity, and perception or experience of outcomes may also be related to legal status and associated stigma. Public health interventions may be more effective by focusing on harm reduction strategies for these drug-specific outcomes.

Abstract
Alcohol consumption has regularly decreased in France since the 1950s, essentially in connection with the decrease of wine consumption, with disaffection for the "table wine", for the benefit of better quality wines that are drunk in lesser quantity. France is still part of the most alcohol drinking countries in the European Union but is no longer situated at the very top of the ranking. General population surveys results tend to confirm the evolution of sale of alcohol: since 1992, among 15-75 years old, alcohol daily users proportion was divided by two, from 24% in 1992 to 11% in 2010, currently replaced by a more occasional use. We indeed observe in the general population a profile of young adults having a strong and punctual consumption, and an older profile of less important but regular consumption. The proportion of problematic alcohol users remains stable, concerning approximately a person on 10 in the adult population. The part of persons who declared they have drunk six glasses or more during the same occasion at least once a month during the last twelve months increased from 15% in 2005 to 18% in 2010. Binge drinking and the frequency of drunkenness have increased among teenagers and young adults these last years. These behaviors can lead to short term risks, such as accidents, undergone violence, unwanted or unprotected sexual intercourse, even coma, whereas chronic alcohol use can lead to numerous hepatic, cardiovascular and neuropsychiatric complications, as well as cancers. With such sanitary consequences, alcohol is a major risk factor of avoidable morbidity and premature mortality. The beneficial effect that seems to have a moderate consumption of alcohol on the risk of death by cardiovascular diseases has brought about recurring scientific controversies. However, its major noxious effects in terms of non-transmitted diseases should remain the major point in public health decisions on alcoholization.

Abstract
BACKGROUND Harms from alcohol experienced by someone other than the drinker have received increasing attention of late, but have not been compared to harms from others' drug use. The aim of the current study is to compare the reported harms that are attributable to the alcohol use of others to those attributable to drugs, distinguishing between different types of harm in order to highlight how reported harms may be influenced by perception and social standing of use of the substance. METHOD Respondents aged 16-24 from Victoria, Australia, completed the Victorian Youth Alcohol and Drug Survey (n=5001), including questions on demographics, drug and alcohol consumption, on the types of harms they experienced attributable to drugs and alcohol, as well as harms they perpetrated after using drugs or alcohol. RESULTS For both drug and alcohol related harms, reports of harms loaded into two groups using multiple correspondence analysis: tangible harms such as assault, and amenity impacts such as being annoyed by people under the influence. Amenity impacts attributed to alcohol were more likely to be experienced by those who reported drug use and vice versa, while the tangible impacts were more likely to be reported by those who used both drugs and alcohol. CONCLUSIONS Reports of amenity impacts from others appear to be influenced by the perception of the drug in question more than tangible impacts such as assault. Particularly for amenity impacts, the greater stigma attached to drug use may make respondents more likely to consider themselves harmed by drugs than they would when compared to alcohol, something that needs to be taken into account when assessing harms by either alcohol or drugs.

Abstract
BACKGROUND Harm ratings of substances help in understanding the perception toward substance use and formulating policies. Evidence of such harm ratings by substance users and their caregivers provides a clearer perspective of those who experience and observe such harm closely. MATERIALS AND METHODS Substance users and their caregivers were recruited from the Drug De-addiction and Treatment Centre of PGIMER, Chandigarh. Sociodemographic details of the subjects were noted. The subjects were then asked to rate a list of psychoactive preparations according to the harms they thought the preparation caused. The list of substances was developed taking into consideration substance commonly encountered in the geographical area. The harm ratings were transformed on a scale of 0-100. RESULTS All subjects were males and majority of them were educated above 10(th) standard, were not employed and belonged to urban background. Most of them had taken psychoactive substances in their lifetimes but were currently abstinent. Most of the subjects endorsed intravenous drugs as the most harmful, followed by heroin. Beer and chewable tobacco considered the least harmful substances. Greater degree of education was associated with lower harm rankings for heroin, cannabis, dextropropoxyphene, and raw opium; while urban residence was associated with greater harm ratings for cannabis and raw opium. Differences in the harms were perceived for different preparations of the same active compound for alcohol and nicotine. CONCLUSION Harm ratings of substances can be a useful guide while formulating policies and allocating resources. Need for further research extending this pilot study is emphasized.

Abstract
Parrott recently published a review of literature on MDMA/ecstasy. This commentary is a response to the content and tenor of his review, which mischaracterizes the literature through misstatement and omission of contrary findings, and fails to address the central controversies in the literature. The review makes several erroneous statements concerning MDMA-assisted psychotherapy, such as incorrect statements about research design and other statements that are baseless or contradicted by the literature. Though it critiques an attempt by other authors to characterize the risks of MDMA, the review fails to produce a competing model of risk assessment, and does not discuss potential benefits. Parrott does not represent an even-handed review of the literature, but instead recites dated misconceptions about neurotoxicity concerns involving the recreational drug ecstasy, which do not relate directly to the use of pure MDMA in a therapeutic setting. Unchallenged, Parrott's report may deter researchers from further investigating an innovative treatment that in early clinical trials has demonstrated lasting benefits for people with chronic, treatment-resistant post-traumatic stress disorder.

Abstract
OBJECTIVES Despite the great impact the migration has had in economic, social and health-related fields, and the repercussions of alcohol consumption on them, few data exist concerning the extent of alcohol consumption in migrant workers. The aims of this study were to identify workers with a hazardous drinking problem by means of a self-reported questionnaire (Alcohol Use Disorders Identification Test-AUDIT) and a biomarker (carbohydrate-deficient transferrin-CDT) and to ascertain associated risk factors. METHODS A cross-sectional survey was conducted using a random sample of 385 migrant workers, undergoing a routine health examination as part of occupational health services. RESULTS The results showed that 13.8% (n=53) of the workers were screened as positive with the AUDIT (≥8) and/or CDT (>2.6) and identified as hazardous drinkers and that 53.8% (n=207) were teetotallers. Being a man (OR: 2.0), working in the construction industry (OR: 2.8) or agriculture (OR: 2.2), being resident in Spain for more than 7 years (OR: 2.3) and sharing a house with friends were the factors most closely associated with hazardous drinking. CONCLUSIONS Prevention-orientated programs, adjusted to the characteristics of each country and the origin of the migrants themselves, should be instituted to modify the drinking habits of migrant workers considered at risk.

Abstract
BACKGROUND Frequent cannabis users are at high risk of dependence, still most (near) daily users are not dependent. It is unknown why some frequent users develop dependence, whereas others do not. This study aims to identify predictors of first-incidence DSM-IV cannabis dependence in frequent cannabis users. METHODS A prospective cohort of frequent cannabis users (aged 18-30, n=600) with baseline and two follow-up assessments (18 and 36 months) was used. Only participants without lifetime diagnosis of DSM-IV cannabis dependence at baseline (n=269) were selected. Incidence of DSM-IV cannabis dependence was established using the Composite International Diagnostic Interview version 3.0. Variables assessed as potential predictors of the development of cannabis dependence included sociodemographic factors, cannabis use variables (e.g., motives, consumption habits, cannabis exposure), vulnerability factors (e.g., childhood adversity, family history of mental disorders or substance use problems, personality, mental disorders), and stress factors (e.g., life events, social support). RESULTS Three-year cumulative incidence of cannabis dependence was 37.2% (95% CI=30.7-43.8%). Independent predictors of the first incidence of cannabis dependence included: living alone, coping motives for cannabis use, number and type of recent negative life events (major financial problems), and number and type of cannabis use disorder symptoms (impaired control over use). Cannabis exposure variables and stable vulnerability factors did not independently predict first incidence of cannabis dependence. CONCLUSIONS In a high risk population of young adult frequent cannabis users, current problems are more important predictors of first incidence cannabis dependence than the level and type of cannabis exposure and stable vulnerability factors.

Abstract
One of the characteristics of people suffering from addictive behaviors is the tendency to be distracted by drug cues. This attentional bias for drug cues is thought to lead to increased craving and drug use, and may draw individuals into a vicious cycle of drug addiction. In the current study we developed a Dutch version of the cannabis Stroop task and measured attentional bias for cannabis words in a group of heavy cannabis users and matched controls. The classical Stroop task was used as a global measure of cognitive control and we examined the relationship between cognitive control, cannabis-related problems, cannabis craving and cannabis attentional bias. Using our version of the cannabis Stroop task, a group of heavy cannabis users showed attentional bias to cannabis words, whereas a control group of non-users did not. Furthermore, within the group of cannabis users, those who were clinically recognized as dependent showed a stronger attentional bias than the heavy, non-dependent users. Cannabis users who displayed reduced cognitive control (as measured with the classical Stroop task) showed increased session-induced craving. Contrary to expectations, however, cognitive control did not appear to modulate the relationship between attentional bias to cannabis words (cannabis Stroop task) and cannabis dependence. This study confirmed the relationship between cannabis dependence and attentional bias and extends this by highlighting a moderating role for cognitive control, which may make some more vulnerable to craving.

Personalized risk assessment of drug-related harm is associated with health outcomes. PLoS One 2013; 8:e79754. [PMID: 24223192 PMCID: PMC3819243 DOI: 10.1371/journal.pone.0079754] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2013] [Accepted: 10/02/2013] [Indexed: 11/29/2022] Open
Abstract
Background The Independent Scientific Committee on Drugs (ISCD) assigned quantitative scores for harm to 20 drugs. We hypothesized that a personalized, ISCD-based Composite Harm Score (CHS) would be associated with poor health outcomes in polysubstance users. Methods A prospective community sample (n=293) of adults living in marginal housing was assessed for substance use. The CHS was calculated based on the ISCD index, and the personal substance use characteristics over four weeks. Regression models estimated the association between CHS and physical, psychological, and social health outcomes. Results Polysubstance use was pervasive (95.8%), as was multimorbid illness (median 3, possible range 0–12). The median CHS was 2845 (interquartile range 1865–3977). Adjusting for age and sex, every 1000-unit CHS increase was associated with greater mortality (odds ratio [OR] 1.47, 95% confidence interval [CI] 1.07–2.01, p = 0.02), and persistent hepatitis C infection (OR 1.29, 95% CI 1.02–1.67, p = 0.04). The likelihood of substance-induced psychosis increased 1.39-fold (95% CI 1.13–1.67, p = 0.001). The amount spent on drugs increased 1.51-fold (1.40–1.62, p < 0.001) and the odds of having committed a crime increased 1.74-fold (1.46–2.10, p < 0.001). Multimorbid illness increased 1.43-fold (95% CI 1.26–1.63, p < 0.001). Conclusions Greater CHS predicts poorer physical, psychological, and social health, and may be a useful quantitative, personalized measure of risk for drug-related harm.

Abstract
Background The classical serotonergic psychedelics LSD, psilocybin, mescaline are not known to cause brain damage and are regarded as non-addictive. Clinical studies do not suggest that psychedelics cause long-term mental health problems. Psychedelics have been used in the Americas for thousands of years. Over 30 million people currently living in the US have used LSD, psilocybin, or mescaline. Objective To evaluate the association between the lifetime use of psychedelics and current mental health in the adult population. Method Data drawn from years 2001 to 2004 of the National Survey on Drug Use and Health consisted of 130,152 respondents, randomly selected to be representative of the adult population in the United States. Standardized screening measures for past year mental health included serious psychological distress (K6 scale), mental health treatment (inpatient, outpatient, medication, needed but did not receive), symptoms of eight psychiatric disorders (panic disorder, major depressive episode, mania, social phobia, general anxiety disorder, agoraphobia, posttraumatic stress disorder, and non-affective psychosis), and seven specific symptoms of non-affective psychosis. We calculated weighted odds ratios by multivariate logistic regression controlling for a range of sociodemographic variables, use of illicit drugs, risk taking behavior, and exposure to traumatic events. Results 21,967 respondents (13.4% weighted) reported lifetime psychedelic use. There were no significant associations between lifetime use of any psychedelics, lifetime use of specific psychedelics (LSD, psilocybin, mescaline, peyote), or past year use of LSD and increased rate of any of the mental health outcomes. Rather, in several cases psychedelic use was associated with lower rate of mental health problems. Conclusion We did not find use of psychedelics to be an independent risk factor for mental health problems.

Abstract
AIMS This study sought to quantify the perceptions of damage and benefit, for users and society, associated with five addictive substances (alcohol, tobacco, cannabis, cocaine and heroin) and one addictive behavior (gambling), in a large sample representative of the French population. We compared with expert assessments and investigated the effects of substance consumption on these perceptions. FINDINGS The ranking of substances by the lay public is very divergent from that of experts. The public overestimates damage to users and to society and underestimates the benefit, in comparison with experts, for all substances. Alcohol is the only exception, with damage and benefit perceptions similar to those of experts. Heroin and cocaine are perceived as the two most dangerous substances. The damage of cannabis and alcohol are judged to be equivalent. The three legal substances are associated with the highest overall benefit, although cannabis has the highest perceived benefit for users. Substances with the highest perceived benefit tend to be associated with perception of lower levels of damage. Individuals with an history of substance use have a perception of the damage and the benefit for that substance which is more congruent with experts, including a similar ranking of substances. CONCLUSIONS Prevention campaigns focused on perceptions of damage alone have reached their limits. The perception of benefit should be taken into account in early interventions with illegal substance users.

Abstract
BACKGROUND Several studies suggest a high prevalence of cannabis use before and during imprisonment, but subjective perspectives of detainees and staff towards its use in prison are lacking. This issue was explored in the framework of an observational study addressing tobacco use in three Swiss prisons in 2009 and 2010 that involved multiple strands (quantitative and qualitative components). This article presents qualitative data on cannabis use collected in one of the settings. METHODS We used in-depth semi-structured interviews with both detainees and staff to explore their attitudes towards cannabis in one post-trial male Swiss prison. We performed specific coding and thematic analysis for cannabis with the support of ATLAS.ti, compared detainees' and staff's opinions, and considered the results with regard to drug policy in prison in general. RESULTS 58 participants (31 male offenders, mean age 35 years, and 27 prison staff, mean age 46 years, 33% female) were interviewed. Detainees estimated the current use of cannabis use to be as high as 80%, and staff 50%. Participants showed similar opinions on effects of cannabis use that were described both at individual and institutional levels: analgesic, calming, self-help to go through the prison experience, relieve stress, facilitate sleep, prevent violence, and social pacifier. They also mentioned negative consequences of cannabis use (sleepiness, decreased perception of danger and social isolation), and dissatisfaction regarding the ongoing ambiguous situation where cannabis is forbidden but detection in the urine was not sanctioned. However, the introduction of a more restrictive regulation induced fear of violence, increased trafficking and a shift to other drug use. CONCLUSION Although illegal, cannabis use is clearly involved in daily life in prison. A clearer and comprehensive policy addressing cannabis is needed, including appropriate measures tailored to individual users. To sustain a calm and safe environment in prison, means other than substance or medication use are required.

Abstract
There have been several recent efforts in the UK and the Netherlands to describe the harms of psychoactive substances based on ratings of either experts or drug users. This study aimed to assess the perceived benefits as well as harms of widely used recreational drugs, both licit and illicit, in an international sample of drug users. The survey was hosted at https://www.internationaldrugsurvey.org/ and was available in three languages. Residents reported their experience of 15 commonly used drugs or drug classes; regular users then rated their harms and benefits. In all, 5791 individuals from over 40 countries completed the survey, although the majority were from English speaking countries. Rankings of drugs differed across 10 categories of perceived benefits. Skunk and herbal cannabis were ranked consistently beneficial, whilst alcohol and tobacco fell below many classified drugs. There was no correlation at all between users' harm ranking of drugs and their classification in schedules of the USA or ABC system in the UK. Prescription analgesics, alcohol and tobacco were ranked within the top 10 most harmful drugs. These findings suggest that neither the UK nor US classification systems act to inform users of the harms of psychoactive substances. It is hoped the results might inform health professionals and educators of what are considered to be both the harms and benefits of psychoactive substances to young people.

Abstract
INTRODUCTION AND AIMS The study aimed to determine injecting drug users' (IDU) attitudes, and correlates of attitudes, towards continued prohibition, decriminalisation or legalisation of the major illicit drugs. DESIGN AND METHODS This study used structured interview with 300 IDUs who had injected on at least a weekly basis over the preceding 12 months. RESULTS Methamphetamine was rated the most harmful of the five illicit substances and cannabis the lowest. By far the highest level of support for legislative change was for cannabis, with only 8.7% supporting continued prohibition. While there was majority support for change to the legal status of heroin, the modal position was for decriminalisation. Support for changing the status of the three illicit psychostimulants was low, with the majority believing that methamphetamine (63.3%), cocaine (53.3%) and 3,4-methylenedioxy-N-methylamphetamine (53.3%) should remain illegal. Demographic characteristics were largely unrelated to attitudes. Lower levels of perceived harm were associated with increased likelihood of support for legalisation of all substances. Recent use was positively related to support for both decriminalisation and legality of heroin, but was not associated with views on other substances. Higher lifetime polydrug use was associated with support for the legalisation of heroin, methamphetamine, cocaine and 3,4-methylenedioxy-N-methylamphetamine. DISCUSSION AND CONCLUSIONS IDUs expressed nuanced views on different substances. In policy debates, care should be taken not to speak for IDUs by imputing their beliefs. It is clear that the fact that a group uses illegal drugs does not necessarily imply that they support changes to their legal status.

Abstract
Chronic use at high dose of illicit drugs, alcohol and tobacco is associated with physical disease. The relative physical harm of these substances has not been described before, but will benefit the guiding of policy measures about licit and illicit substances. The physical harm of 19 addictive substances (including alcohol and tobacco), consisting of toxicity and the risk and severity of somatic disease (not psychiatric disease) was assessed based on literature data and the professional opinion of experts using scores ranging from 0 (no physical harm) to 3 (very serious physical harm). For alcohol, tobacco and some illicit drugs strong associations between long-term use or use in high dose versus the risk of somatic disease have been described, whereas for other substances such data are not available. Magic mushrooms, LSD and methylphenidate obtained relatively low scores (0.45-0.65) for physical harm, whereas relatively high scores were given for heroin (2.09), crack (2.32), alcohol (2.13) and tobacco (2.10). For cannabis, tobacco, and alcohol the estimated societal disease burden was higher than at individual level. The present ranking solely based on their physical harm was very similar to a previous ranking based on a combination of dependence liability, physical harm and social impairments.

Abstract
The aim of this paper is to create awareness of the negative health impact and economic burden and benefits associated to alcohol consumption. Worldwide about two billion people consume alcohol. Low intake of alcohol has a minor protective cardiovascular effect. On the other hand, even moderate alcohol consumption appears to be weakly, but significantly, associated to a limited number of chronic diseases. Alcohol causes a considerable economic burden to society due to the high absolute number of alcohol consumers. As such, alcohol abuse is more harmful for public health and society than illicit drug use. Some 3.7% of alcohol consumers (worldwide 76 million people) have an alcohol use disorder leading to 60-70% of the societal costs related to alcohol. Therefore, policy measures should, in addition to regulatory measures to reduce alcohol use, aim at closing the treatment gap and improving treatment effectiveness of people with an alcohol use disorder. The key message is that policy-makers unjustifiably focus on the harm of illicit drugs, whereas they underestimate the harm of alcohol use. Policy makers should therefore consider alcohol to be at least as harmful as illicit drugs and invest more in prevention and harm reduction strategies for alcohol abuse and dependence.

Abstract
AIMS We aimed to explain the association between exposure to a cigarette advertisement and favorable attitudes towards the advertisement. METHODS We used data from an observational cross-sectional study with a sample of 3,415 German schoolchildren aged 10-17 years. Cigarette advertising exposure was assessed with an image of a Marlboro ad, asking for contact frequency (number of times seen the ad) and brand name. Liking of the ad was measured with two items (alpha = 0.78). RESULTS We found a positive linear association between exposure to the Marlboro ad and liking it. This association remained significant (standardized β = 0.09; p < 0.001) even after statistical control for smoking status, smoking of friends and parents, attitudes towards smoking in general, cigarette advertising receptivity (having a favorite cigarette ad), exposure to other advertisings, age, sex, socioeconomic status, rebelliousness and sensation seeking, self-reported school performance, and study region. CONCLUSIONS The association between exposure to an advertisement and liking it was robust and could not be fully explained without referring to either unmeasured confounding or implicit advertising effects (e.g. mere exposure). Implicit effects have implications for prevention strategies as it may be very difficult to counteract unconscious advertising effects.

Abstract
This paper considers drug classifications and terms widely used in US survey research, and compares these to classifications and terms used by drug users. We begin with a critical review of drug classification systems, including those oriented to public policy and health services as well as survey research. We then consider the results of a pile sort exercise we conducted with 76 respondents within a mixed method study of Southeast Asian American adolescent and young adult drug users in urban Northern California, USA. We included the pile sort to clarify how respondents handled specific terms which we understood to be related to Ecstasy and methamphetamines. Results of the pile sort were analyzed using graphic layout algorithms as well as content analysis of pile labels. Similar to the national surveys, our respondents consistently differentiated Ecstasy terms from methamphetamine terms. We found high agreement between some specific local terms (thizz, crystal) and popular drug terms, while other terms thought to be mainstream (crank, speed) were reported as unknown by many respondents. In labeling piles, respondents created taxonomies based on consumption method (in particular, pill) as well as the social contexts of use. We conclude by proposing that divergences between drug terms utilized in survey research and those used by drug users may reflect two opposing tendencies: the tendency of survey researchers to utilize standardized language that constructs persons and experiences as relatively homogeneous, varying only within measurable degrees, and the tendency of drug users to utilize specialized language (argot) that reflects their understandings of their experiences as hybrid and diverse. The findings problematize the validity of drug terms and categories used in survey research.

Abstract
OBJECTIVE To produce an expert consensus hierarchy of harm to self and others from legal and illegal substance use. DESIGN Structured questionnaire with nine scored categories of harm for 19 different commonly used substances. SETTING/PARTICIPANTS 292 clinical experts from across Scotland. RESULTS There was no stepped categorical distinction in harm between the different legal and illegal substances. Heroin was viewed as the most harmful, and cannabis the least harmful of the substances studied. Alcohol was ranked as the fourth most harmful substance, with alcohol, nicotine and volatile solvents being viewed as more harmful than some class A drugs. CONCLUSIONS The harm rankings of 19 commonly used substances did not match the A, B, C classification under the Misuse of Drugs Act. The legality of a substance of misuse is not correlated with its perceived harm. These results could inform any legal review of drug misuse and help shape public health policy and practice.

Abstract
Background Alcohol drinking is a risk factor for harm and disease. A low level of drinking among non-Western immigrants may lead to less alcohol-related harm and disease. The first aim of this study was to describe frequency of drinking in two generations of immigrants in Oslo, contrasting the result to drinking frequency among ethnic Norwegians. The second aim was to study how frequency of drinking among adult immigrants was associated with social interaction with their own countrymen and ethnic Norwegians, acculturation, age, gender, socioeconomic factors and the Muslim faith. Method The Oslo Health Study (HUBRO) was conducted during the period 2000 to 2002 and consisted of three separate surveys: a youth study (15-16-year-olds, a total of 7343 respondents, response rate 88.3%); adult cohorts from 30 to 75 years old (18,770 respondents, response rate 46%); the five largest immigrant groups in Oslo (aged 20–60 years, a total of 3019 respondents, response rate 39.7%). Based on these three surveys, studies of frequency of drinking in the previous year (four categories) were conducted among 15-16-year-olds and their parents’ generation, 30-60-year-old Iranians, Pakistanis, Turks and ethnic Norwegians. A structural equation model with drinking frequency as outcome was established for the adult immigrants. Results Adults and youth of ethnic Norwegian background reported more frequent alcohol use than immigrants with backgrounds from Iran, Turkey and Pakistan. Iranians reported a higher drinking frequency than Turks and Pakistanis. In the structural equation model high drinking frequency was associated with high host culture competence and social interaction, while high own culture competence was associated with low drinking frequency. Adult first-generation immigrants with a longer stay in Norway, those of a higher age, and females drank alcohol less frequently, while those with a higher level of education and work participation drank more frequently. Muslim immigrants reported a significantly lower drinking frequency than non-Muslims, although this did not apply to Iranians. Conclusions The existence and growth in Western societies of immigrant groups with low-level alcohol consumption contributed to a lower level of consumption at the population level. This may imply reduced drinking and alcohol-related harm and disease even among ethnic Norwegians.

"I'm not afraid of those ones just 'cause they've been prescribed": perceptions of risk among illicit users of pharmaceutical opioids. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2012; 23:374-84. [PMID: 22417823 DOI: 10.1016/j.drugpo.2012.01.012] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2011] [Revised: 01/23/2012] [Accepted: 01/24/2012] [Indexed: 11/23/2022]
Abstract
BACKGROUND There has been a rise in the illicit use of pharmaceutical opioids ("pain pills") in the United States. Conducted with young adult non-medical users of pharmaceutical opioids, this study uses qualitative methods and cultural consensus analysis to describe risk perceptions associated with pharmaceutical opioids and to determine patterns of cultural sharing and intra-cultural variation of these views. METHODS The qualitative sub-sample (n=47) was selected from a larger sample of 396 young adults (18-23 years old), who were participating in a natural history study of illicit pharmaceutical opioid use. Qualitative life history interviews, drug ranking task, and cultural consensus analysis were used to elicit participant views about risks and harms associated with pain pills and other drugs, as well as alcohol and tobacco. RESULTS Cultural consensus analysis revealed that the participants shared a single cultural model of drug risks, but the level of agreement decreased with the increasing range of drugs ever used. Further, those with more extensive drug use histories differed from less "experienced" users in their views about OxyContin and some other drugs. Overall, pain pills were viewed as addicting and potentially deadly substances, but these properties were linked to the patterns and methods of use, as well as characteristics of an individual user. Further, risks associated with pharmaceutical opioids were further curtailed because they "came from the doctor," and thus had a legitimate aspect to their use. CONCLUSIONS This study highlights potential problems with universal approaches to substance use prevention and intervention among young people since such approaches ignore the fact that substance use education messages may be experienced differently depending on an individual's drug use history and his/her perceptions of drug risks. Findings reported here may be useful in the development of prevention and intervention programs aimed at reducing the harm associated with illicit use of pain pills.

Abstract
In this paper we discuss the relative physical, psychological and social harms of the two most frequently used intoxicant drugs in the UK, namely cannabis and alcohol. Over the past 40 years, the use of both drugs has risen significantly with differential consequences. It is argued that increased policing of cannabis use under the current drug classification system will lead to increased criminalization of young people, but is unlikely to significantly reduce the rates of schizophrenia and psychosis. In comparison, increases in alcohol drinking are related to significant increases in liver cirrhosis hospital admissions and mortality, at a time when mortality rates from other major causes are on the decline. A recent expert-led comparison of the health and social harms to the user and to others caused by the most commonly used drugs in the UK showed alcohol to be more than twice as harmful as cannabis to users, and five times as harmful as cannabis to others. The findings underline the need for a coherent, evidence-based drugs policy that enables individuals to make informed decisions about the consequences of their drug use.

Abstract
BACKGROUND/AIMS We investigated the psychometric properties of a German translation of the 12-item Autonomy over Tobacco Scale (AUTOS) among 1,195 eighth-grade students. METHODS Data for this study were collected as part of the fourth wave of data collection of the Smokefree Class Competition intervention in the Saxony-Anhalt region of Germany. Students from the control arm of the Smokefree Class Competition study who indicated that they had ever smoked 'at least a few puffs' on a cigarette were classified as ever-smokers. They self-completed questionnaires distributed by teachers. RESULTS AUTOS scores ranged from 0 to 36 with a distribution highly skewed toward lower-response categories. Inter-item correlations ranged from 0.65 to 0.89 (mean = 0.79, SD = 0.06). Composite reliability for the AUTOS was high (Ω = 0.96) and 3 lower-order factors were also reliable (withdrawal: 0.89, psychological dependence: 0.91, cue-induced cravings: 0.87). Concurrent validity was supported by strong relationships between the AUTOS and both lifetime cigarette consumption and current smoking frequency. Youths were 18 times more likely to be current smokers (95% CI = 11.9-27.2, p < 0.001) if they endorsed any AUTOS item. CONCLUSION The German AUTOS is reliable and valid, and the results are consistent with the English AUTOS for use with adolescents.

Odenwald M, Semrau P. Reducing dropout among traumatized alcohol patients in detoxification treatment: a pilot intervention study. Eur Addict Res 2012; 18:54-63. [PMID: 22178762 DOI: 10.1159/000333336] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2011] [Accepted: 09/14/2011] [Indexed: 11/19/2022]
Abstract
Dropout rates from detoxification treatment are high. We tested whether high trauma event load was related to a higher dropout from alcohol detoxification. Furthermore, we studied the feasibility and effects of a short psychoeducational tool to increase retention among traumatized alcohol in-patients. Retention and treatment length were compared between treatment as usual (TAU) and standard therapy plus a psychoeducational group intervention on alcohol drinking related to stress and trauma (PAST). Patients with high trauma load were identified with the Trauma History Questionnaire. Of the 159 in-patients treated during the study period, 66 were included in the analysis: 33 in TAU and 33 in PAST. Sociodemographic characteristics did not differ between the groups. During TAU, patients with high trauma load tended to drop out more often (p = 0.056). Among patients with high trauma load, retention level increased from 29 to 80% (p = 0.006), and among those with low trauma load from 63 to 83% (p = 0.250). Treatment length only tendentially improved among patients with lower burden (p = 0.056). The pilot study supports the idea that detoxification treatment dropout occurs more often among alcohol patients with high trauma load and that their retention can be increased by a psychoeducational group intervention.

Abstract
AIMS To investigate associations between cannabis use and subsequent receipt of social welfare assistance. DESIGN, SETTING AND PARTICIPANTS The Young in Norway Longitudinal Study. A population-based Norwegian sample (n = 2606) was followed-up from adolescence to late 20s. Self-report data were merged with data from national registers. MEASUREMENTS Data were extracted on the use of alcohol, tobacco and cannabis and other illegal substances. Information was also retrieved on socio-demographic and family factors, academic achievement, conduct problems and mental health. National registers provided data on social welfare assistance, educational level and crime statistics. FINDINGS We observed prospective bivariate associations between increasing levels of cannabis use and subsequent social welfare assistance (P < 0.0001). The associations were reduced after adjusting for a range of potentially confounding factors, but remained significant. Frequent cannabis users were at highly increased risk for subsequently receiving social welfare assistance. At 28 years, those with 50+ times cannabis use during the previous 12 months and had an odds ratio of 9.3 (95% confidence interval: 4.3-20.1) for receiving social welfare assistance in the following 2-year span. Users of cannabis also had longer periods of receiving social welfare assistance than others (P < 0.0001) and were less likely to leave the welfare assistance system (P < 0.0001). CONCLUSIONS In Norway the use of cannabis is linked with subsequent receipt of social welfare assistance whether the consequences are related to use of the substance per se, or to cultural factors and the illegal status of the cannabis. Future research should attempt to understand the interactions of factors behind these associations.

The Dutch Cannabis Dependence (CanDep) study on the course of frequent cannabis use and dependence: objectives, methods and sample characteristics. Int J Methods Psychiatr Res 2011; 20:169-81. [PMID: 21815231 PMCID: PMC3467998 DOI: 10.1002/mpr.345] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2010] [Revised: 01/19/2011] [Accepted: 05/17/2011] [Indexed: 11/11/2022] Open
Abstract
This paper presents an overview of the prospective cohort design of the Dutch Cannabis Dependence (CanDep) study, which investigates (i) the three-year natural course of frequent cannabis use (≥ three days per week in the past 12 months) and cannabis dependence; and (ii) the factors involved in the transition from frequent non-dependent cannabis use to cannabis dependence, and remission from dependence. Besides its scientific relevance, this knowledge may contribute to improve selective and indicated prevention, early detection, treatment and cannabis policies. The secondary objectives are the identification of factors related to treatment seeking and the validation of self report measures of cannabis use. Between September 2008 and April 2009, baseline data were collected from 600 frequent cannabis users with an average age of 22.1 years, predominantly male (79.3%) and an average cannabis use history of 7.1 years; 42.0% fulfilled a (12-month DSM-IV) diagnosis of cannabis dependence. The response rate was 83.7% after the first follow up at 18 months. The second and last follow-up is planned at 36 months. Computer assisted personal interviews (CAPI) were conducted which covered: cannabis use (including detailed assessments of exposure, motives for use and potency preference); use of other substances; DSM-IV internalizing and externalizing mental disorders; treatment seeking; personality; life events; social support and social functioning.

[PMID: 21256914 DOI: 10.1016/j.yrtph.2011.01.006] [Citation(s) in RCA: 96] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2010] [Revised: 01/11/2011] [Accepted: 01/13/2011] [Indexed: 10/18/2022]
Abstract
In 2007, the Minister of Health of the Netherlands requested the CAM (Coordination point Assessment and Monitoring new drugs) to assess the overall risk of magic mushrooms. The present paper is an updated redraft of the review, written to support the assessment by CAM experts. It summarizes the literature on physical or psychological dependence, acute and chronic toxicity, risk for public health and criminal aspects related to the consumption of magic mushrooms. In the Netherlands, the prevalence of magic mushroom use was declining since 2000 (last year prevalence of 6.3% in 2000 to 2.9% in 2005), and further declined after possession and use became illegal in December 2008. The CAM concluded that the physical and psychological dependence potential of magic mushrooms was low, that acute toxicity was moderate, chronic toxicity low and public health and criminal aspects negligible. The combined use of mushrooms and alcohol and the quality of the setting in which magic mushrooms are used deserve, however, attention. In conclusion, the use of magic mushrooms is relatively safe as only few and relatively mild adverse effects have been reported. The low prevalent but unpredictable provocation of panic attacks and flash-backs remain, however, a point of concern.
