Abstract
This study described cannabis use behavior among college students in Berlin, in particular, differences in use motives between subjects with frequent use and those with signs of cannabis use disorder (CUD). Cross-sectional data were collected via an online survey among Berlin college students ( N=9350; 50.7% women; Mage=24.4). Motivation scales were computed based on an exploratory factor analysis. Effects of these motive scales were compared using multivariate regression models, where the dependent variable was use intensity (ordinal), frequent use (twice or more per week, binary) or a positive substance use disorder screening test (binary). Cannabis use is known to be particularly prevalent among Berlin college students, which was confirmed by our data. The most frequent use motive was enhancement, which, however, was not associated with frequent use or CUD. The motives predicting frequent use (sociability) are different from motives predicting CUD (coping), even when controlling for a wide array of covariates.

Moeller SJ, Platt JM, Wu M, Goodwin RD. Perception of treatment need among adults with substance use disorders: Longitudinal data from a representative sample of adults in the United States. Drug Alcohol Depend 2020; 209:107895. [PMID: 32078975 PMCID: PMC7418940 DOI: 10.1016/j.drugalcdep.2020.107895] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2019] [Revised: 01/31/2020] [Accepted: 02/04/2020] [Indexed: 01/06/2023]
Abstract
BACKGROUND Most individuals with substance use disorders (SUDs) do not seek treatment. Lack of perceived treatment need (PTN) is one contributing factor, but little is known about PTN over time. We estimated whether PTN changed over three years among those with SUDs in the United States and identified select variables, including sociodemographics and symptom burden, that predict malleability vs. stability of PTN. METHODS Data were from Waves 1 (collected 2001-2002) and 2 (collected 2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC); 1695 adults who met DSM criteria for alcohol or non-alcohol SUD at Wave 1 and maintained ≥1 diagnostic symptom at Wave 2 were included. RESULTS Most individuals with SUDs (77.2%) did not perceive a need for treatment at Wave 1 baseline. Only about 1 in 8 individuals not perceiving a need for treatment in Wave 1 came to perceive a need in Wave 2 (adjusted odds ratio = 0.18, 99% confidence interval = 0.11-0.29). In contrast, about half the individuals who perceived a need for treatment in Wave 1 no longer did so in Wave 2, despite maintaining ≥1 SUD symptom. Married respondents, and respondents with more SUD symptoms, were more likely to transition from low- to high-PTN status three years later. Respondents with incomes >$35,000 were less likely to transition to high-PTN status three years later. CONCLUSIONS PTN was more likely to decline than increase over time. Low PTN appears to be stable among adults with SUDs in the United States, presenting a potentially enduring barrier to treatment-seeking.

Front Psychiatry 2020; 11:580771. [PMID: 33424660 PMCID: PMC7785720 DOI: 10.3389/fpsyt.2020.580771] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Accepted: 11/23/2020] [Indexed: 11/13/2022] Open
Abstract
Objective: We previously found that chronic ketamine usages were associated with various psychotic and cognitive symptoms mimicking schizophrenia. The blockade of the NMDA receptor and subsequent nitric oxide synthase 1 (NOS1) dysfunction were found to be closely correlated with schizophrenia including NOS1 gene polymorphisms. We examined the allelic variants of the gene coding neuronal nitric oxide synthase 1 (NOS1) in chronic ketamine users in the Chinese population and analyzed the association between NOS1 gene polymorphism and psychopathological symptoms in chronic ketamine users. The association between the NOS1 polymorphism and ketamine use characteristics was also examined. Methods: One hundred ninety seven male chronic ketamine users and 82 controls were recruited. Four common SNPs of the NOS1 gene, rs6490121, rs41279104, rs3782206, and rs3782219, were examined by real-time PCR with the TaqMan® assay system. Psychopathological symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS), Beck Depression Inventory (BDI), and the Beck Anxiety Inventory (BAI). Results: The genotype distribution of rs6490121 and rs41279104 in chronic ketamine users was significantly different from that in the control (p = 0.0001 and p = 0.002). The G allele frequency of rs6490121 in ketamine users was higher than that in the control (p = 2.23 * 10-6, OR = 3.07, 95% CI = 1.93-4.90). The T allele frequency of rs41279104 in chronic ketamine users was higher than that in the control (p = 0.01, OR = 1.76, 95% CI = 1.14-2.72). The BAI score was significantly different among the three genotypic groups of rs6490121 (F = 6.21, p = 0.002) in ketamine users; subjects of genotype AG and GG had a lower score than subjects of genotype AA. The score of the negative symptom subscale of PANSS was significantly different among the three genotypic groups of rs41279104 (F = 5.39, p = 0.005); in ketamine users, subjects of genotype CT and TT had a higher score than subjects of genotype CC. There was no difference in drug use characteristics in different genotypes of the four NOS1 gene polymorphisms tested in ketamine users (p > 0.05).

Abstract
Berlin is internationally known for its intense nightlife associated with high rates of psychoactive substance use. Previous studies conducted in other cities indicated college students as a group at high risk for substance (mis-)use that was associated with individual psychological and cognitive impairments as well as lower academic performance. The aim of this study was to provide detailed data about the substance use patterns of Berlin college students. In addition, major protective and risk factors were analysed. An online questionnaire assessing sociodemographic data and various relevant aspects of both legal and illegal substance use such as consumption pattern and frequency as well as risk-taking behaviour was developed and distributed among colleges in Berlin. A sample of 9351 participants from 17 different colleges in Berlin completed the questionnaire. The study revealed high lifetime (69.3%), past year (45.9%) and past month (28.3%) prevalence of illicit substance use in the sample. Daily tobacco-smoking, a mental disorder diagnosis, a positive screening for problematic consumption (Cage-AID), bisexual orientation and living in open relationship were main factors positively associated with the prevalence and the extent of illicit substance use. Students in Berlin appear to show higher rates of illicit substance use than was previously reported for age-matched individuals in the general German population and college students in other cities. Thus, they are a relevant target group for early prevention and intervention concerning substance use and abuse.

Abstract
Animal models of drug self-administration are currently the gold standard for making predictions regarding the relative likelihood that a recreational drug substance will lead to continued use and addiction. Such models have been found to have high predictive accuracy and discriminative validity for a number of drug classes including ethanol, nicotine, opioids, and psychostimulants such as cocaine and methamphetamine. Members of the entactogen class of psychostimulants (drugs that produce an "open mind state" including feelings of interpersonal closeness, intimacy and empathy) have been less frequently studied in self-administration models. The prototypical entactogen 3,4-methylenedioxymethamphetamine (MDMA; "Ecstasy") supports self-administration but not with the same consistency nor with the same efficacy as structurally related drugs amphetamine or methamphetamine. Consistent with these observations, MDMA use is more episodic in the majority of those who use it frequently. Nevertheless, substantial numbers of MDMA users will meet the criteria for substance dependence at some point in their use history. This review examines the currently available evidence from rodent self-administration studies of MDMA and two of the new and emerging psychoactive substances (NPS) that produce entactogen type neuropharmacological responses - mephedrone (4-methylmethcathinone; 4MMC; "meow meow") and methylone (3,4-methylenedioxymethcathinone). Overall, the current evidence predicts that these NPS entactogens have enhanced abuse liability compared with MDMA.

Abstract
This study aimed to analyze whether ecstasy consumption is associated with the socioeconomic status in the Municipality of São Paulo, Brazil, from 2000 to 2007. We used an official, reliable and unbiased source supplied by the Department of Narcotics of the State of São Paulo (Denarc) database and the Human Development Index of the districts (HDId) where the seizures occurred. A Spearman correlation test between the average number of ecstasy seizures per million of inhabitants with the HDId was used. There were 190 seizures (totaling 47,934 tablets) spread out in 53 of the 96 districts and 51.6% were concentrated in only 8 districts. The higher rates of ecstasy seizures were directly associated with districts with high HDId that confirmed the association of ecstasy consumption with the socioeconomic status. Itaim-Bibi, Jardim Paulista and Moema were the top three districts with the highest HDId. In these districts, the number of tablets per seizure ranged from as few units to thousands, revealing that not only consumption but also traffic coexist at the same place. Districts with many nightclubs can also influence the incidence of seizures. This knowledge can be useful to help the police from other Brazilian cities to combat ecstasy trafficking.
