Fear of COVID-19 and illicit drug use during COVID-19 pandemic in Japan: a case-control study.

Background: Some people use illicit drugs to relieve stress. However, these drugs cause serious damage not only to individuals but also to society as a whole. Stress caused by the COVID-19 pandemic is considerable, as the number of illicit drug users continues to increase, despite a decrease in the availability of drugs and opportunities to leave the house during the pandemic. Fear of COVID-19 causes stress; however, its association with illicit drug use is not yet understood. In this study, we examined whether the fear of COVID-19 affects the subsequent use of illicit drugs. Methods: We conducted a retrospective longitudinal case-control study using data from an Internet survey performed annually between 2020-2022, with the 2020 survey as the baseline survey and the 2021 and 2022 surveys as follow-up surveys. Those who were illicit drug use-free at the baseline survey but had a history of drug use upon follow-up were defined as the outcome group, whereas those who remained illicit drug use-free at follow-up were defined as the no-outcome group. Logistic regression analysis was conducted between the two groups, using "the fear of COVID-19" as the explanatory variable and adjusting for the effects of confounding factors. The same analysis was conducted by dividing illicit drugs into cannabis and non-cannabis groups, then setting their use as a secondary outcome. Results: The study included 17,800 subjects, 837 of whom used illicit drugs at follow-up and 16,963 who did not use illicit drugs at follow-up. Logistic regression analysis revealed that higher levels of fear over COVID-19 correlated with higher illicit drug use among the participants. However, our analysis of cannabis-only outcomes showed no significant differences. Conclusions: We found that fear of COVID-19 was a contributing factor to illicit drug use. Although the exact mechanism through which fear influences illicit drug use remains unknown, previous studies have shown that fear of certain targets increases illicit drug use, and our study adds to this evidence. However, in this study, we were unable to show a statistically significant causal relationship between fear of COVID-19 and the use of cannabis alone. Further research on the relationship between fear and the use of cannabis or other drugs, for varying focuses of fear, may broaden our knowledge of the different reasons individuals have for using different drugs.

Suicide ideation and psychotropic recreational drug use by adolescents: a systematic review and meta-analysis.

BACKGROUND: Adolescence is characterized by complex and dynamic changes, often involving experimentation, including the use of psychotropic substances. Although it is well-established that recreational psychotropic drugs are associated with suicide ideation in adults, evidence of this association in adolescents remains limited. OBJECTIVE: To investigate the relationship between suicide ideation and psychotropic recreational drug use among adolescents. DESIGN AND SETTING: Systematic review with meta-analysis developed at Universidade Federal de Uberlândia (UFU) and Universidade Estadual de Campinas (UNICAMP), Brazil. METHODS: A search across eight electronic databases for observational studies, without language or publication year restrictions, was conducted. The Joanna Briggs Institute tool was used to assess the risk of bias. Random-effects meta-analyses and odds ratios were used to measure the effects. RESULTS: The search yielded 19,732 studies, of which 78 were included in the qualitative synthesis and 32 in the meta-analysis. The findings indicated that suicidal ideation was 1.96 times more likely (95% confidence interval, CI = 1.47; 2.61) for adolescents who used some drug recurrently and 3.32 times more likely (95%CI = 1.86; 5.93) among those who abused drugs. Additionally, adolescents who used cannabis were 1.57 times more likely (95%CI = 1.34; 1.84) to experience suicide ideation compared with non-users, while cocaine users had 2.57 times higher odds (95%CI = 1.47; 4.50). CONCLUSIONS: Psychotropic recreational drug use is associated with suicidal ideation among adolescents regardless of current or previous use, abuse, or type of substance used.

Psychosocial factors associated with overdose subsequent to Illicit Drug use: a systematic review and narrative synthesis.

BACKGROUND AND AIMS: Psychological and social status, and environmental context, may mediate the likelihood of experiencing overdose subsequent to illicit drug use. The aim of this systematic review was to identify and synthesise psychosocial factors associated with overdose among people who use drugs. METHODS: This review was registered on Prospero (CRD42021242495). Systematic record searches were undertaken in databases of peer-reviewed literature (Medline, Embase, PsycINFO, and Cinahl) and grey literature sources (Google Scholar) for work published up to and including 14 February 2023. Reference lists of selected full-text papers were searched for additional records. Studies were eligible if they included people who use drugs with a focus on relationships between psychosocial factors and overdose subsequent to illicit drug use. Results were tabulated and narratively synthesised. RESULTS: Twenty-six studies were included in the review, with 150,625 participants: of those 3,383-4072 (3%) experienced overdose. Twenty-one (81%) studies were conducted in North America and 23 (89%) reported polydrug use. Psychosocial factors associated with risk of overdose (n = 103) were identified and thematically organised into ten groups. These were: income; housing instability; incarceration; traumatic experiences; overdose risk perception and past experience; healthcare experiences; perception of own drug use and injecting skills; injecting setting; conditions with physical environment; and social network traits. CONCLUSIONS: Global rates of overdose continue to increase, and many guidelines recommend psychosocial interventions for dependent drug use. The factors identified here provide useful targets for practitioners to focus on at the individual level, but many identified will require wider policy changes to affect positive change. Future research should seek to develop and trial interventions targeting factors identified, whilst advocacy for key policy reforms to reduce harm must continue.

Adverse drug effects as a deterrent against willingness to use in the future among nightclub/festival attendees.

INTRODUCTION: It is largely unknown whether adverse effects experienced from recreational drug use affect willingness to use again. This study determined whether adverse effects from select party drugs affect reported willingness to use again in the next month among a high-risk population-people who attend electronic dance music parties at nightclubs or dance festivals. METHODS: Adults (age ≥ 18) entering nightclubs/festivals were surveyed in New York City in 2018-2022 (n = 2981). Participants were asked about past-month use of common party drugs (cocaine, ecstasy, lysergic acid diethylamide [LSD] and ketamine), whether they had experienced a harmful or very unpleasant effect after use in the past 30 days, and whether they intend to use again in the next 30 days if offered by a friend. The relationship between having experienced an adverse outcome and willingness to use again was examined in a bivariable and multivariable manner. RESULTS: Experiencing an adverse effect after past-month cocaine (adjusted prevalence ratio [aPR] = 0.58, 95% confidence interval [CI] 0.35-0.95) or ecstasy use (aPR = 0.45, 95% CI 0.25-0.80) was associated with lower risk for willingness to use again. Adverse effects related to LSD use were related to lower risk of being willing to use again in the bivariable model, but in multivariable models, risk was not attenuated for willingness to use LSD or ketamine again. DISCUSSION AND CONCLUSIONS: Personally experienced adverse effects can deter willingness to use certain party drugs again in this high-risk population. Interventions targeting cessation of recreational party drug use can likely benefit from focusing on deleterious effects of use that have been experienced.

Facets of Gender Expression and Discrimination in Relation to Alcohol and Other Drug Use Severity Among Sexual Minority Women and Gender Diverse Individuals Assigned Female at Birth.

Purpose: Sexual minority women and gender diverse individuals assigned female at birth (SMW+) consistently report more alcohol and other drug (AOD) use severity than heterosexual women, with greater disparities reported among bisexual plus (bi+) SMW (including bisexual, pansexual, queer, and those with attractions to more than one gender regardless of identity). Furthermore, emerging evidence suggests that SMW with masculine gender expression (e.g., SMW with masculine gender appearance) disproportionately experience problematic AOD use compared to those with feminine gender expression. The minority stress model, which has predominantly been investigated in relation to internalized homonegativity and sexuality-based discrimination, may also account for these AOD use disparities. This study examined gender expression, related discrimination, and AOD use severity among SMW+. Methods: In a 2020 sample of SMW+ (n = 236), we investigated AOD use severity in relation to gender expression (appearance, emotional expression, and gender roles) and gender expression-based discrimination after controlling for internalized homonegativity and sexuality-based discrimination through an online survey. Results: Masculine gender roles were associated with AOD use severity, whereas masculine appearance and emotional expression were not. In multivariable models, gender identity was inconsistently associated with alcohol use severity, sexuality-based discrimination was consistently associated with alcohol use severity and inconsistently associated with other drug use severity, and gender expression-based discrimination was associated with neither. Conclusion: This study emphasizes the importance of examining intersecting aspects of minority identity among SMW+, including facets of gender expression, in relation to AOD use severity.

Characteristics and Long Term Follow up of Men Who Suffer Ischemic Priapism Secondary to Recreational Use of Intracavernosal Injectable Medications.

OBJECTIVE: To better understand patient experience, risk factors, culture, and ED outcomes surrounding recreational ICI use that led to ischemic priapism. METHODS: After IRB approval, men presenting for ischemic priapism secondary to recreational ICI use from January 2010 to December 2018 were contacted by mail and then via telephone. Standardized questions were asked of all study participants on the topics of erectile function (IIEF-5), sexual practices, and at-risk behavior at the time of priapism. Qualitative data analysis was performed using grounded theory methodology. RESULTS: 14 men age 24-59 were successfully recruited. All men described themselves as men having sex with men (MSM) and one (7.1%) as having both male and female sexual partners. Average follow up IIEF-5 among participants was 13 (SD 4.0). Eleven men (78.6 %) described illicit drug use at the time of priapism. Qualitative data analysis yielded several preliminary themes: concomitant drug use, naivety, peer pressure, and delay in seeking treatment. Men frequently reported illicit drug use in group sex scenarios and ICI use under pressure to perform sexually or to counteract effects of illicit substances. CONCLUSIONS: Recreational ICI in this cohort was part of a lifestyle of risky behavior. Methamphetamine use and group sex encounters strongly motivate recreational ICI use. Substance abuse centers may offer an entry point into this population for counseling and primary prevention.

Substance use is associated with worse mental health and altered resting state functional connectivity in female university athletes at baseline: A pilot study.

University athletes are at high risk for both substance use and mental health problems. This study examined associations between substance use, mental health symptoms, and the resting state functional connectivity (rsFC) of key neural regions involved in self-monitoring and emotional regulation in a sample of female varsity athletes. 31 female university athletes completed measures of substance use, mental health symptoms, and underwent functional MRI scans during the pre-season. Athletes who were substance users had higher symptoms of depression than non-users (p = 0.04; Hedge's g = 0.81). RsFC differences were observed between users and non-users in orbital frontal cortex (OFC) and bilateral hippocampal seeds, and negative associations between depression symptoms and rsFC in the left hippocampus and posterior cingulate cortex were observed in cannabis users. In female athletes, substance use is associated with greater self-reported depression symptoms and altered rsFC in self-monitoring and emotional regulation regions of the brain.

Adolescent emotional disorder symptoms and transdiagnostic vulnerabilities as predictors of young adult substance use during the COVID-19 pandemic: mediation by substance-related coping behaviors.

The COVID-19 pandemic presents unique stressors (e.g. social isolation) that may increase substance use risk among young adults with a history of emotional disturbance. This study examined whether emotional disorder symptoms and transdiagnostic vulnerabilities during adolescence predicted young adult substance use during COVID-19, and whether using substances to cope with the pandemic's social conditions mediated these associations. Adolescents (N = 2,120) completed baseline surveys assessing transdiagnostic emotional vulnerabilities (anhedonia, distress intolerance, anxiety sensitivity, negative urgency) and symptoms (major depression[MD], generalized anxiety[GAD], panic disorder[PD], social phobia[SP], obsessive-compulsive disorder[OCD]) in adolescence (September-December 2016; M[SD] age = 17.45[0.38]). At follow-up (May-August 2020; M[SD] age = 21.16[0.39]), past 30-day substance use and using substances to cope with social isolation during the pandemic were reported. Adjusted models showed that baseline distress intolerance, anxiety sensitivity, negative urgency, and MD symptoms each significantly predicted higher number of past-month single-substance using days and number of substances used at follow-up (ßs = 0.04-0.06). In each case, associations were mediated by tendency to use substances to cope with the pandemic (ßindirect range: 0.028-0.061). To mitigate disproportionate escalation of substance use in young adults with a history of certain types of emotional disturbance, interventions promoting healthy coping strategies to deal with the pandemic's social conditions warrant consideration.

Intoxication by a synthetic cannabinoid (JWH-018) causes cognitive and psychomotor impairment in recreational cannabis users.

BACKGROUND: Smoking mixtures containing synthetic cannabinoids (SCs) have become very popular over the last years but pose a serious risk for public health. Limited knowledge is, however, available regarding the acute effects of SCs on cognition and psychomotor performance. Earlier we demonstrated signs of impairment in healthy volunteers after administering one of the first SCs, JWH-018, even though subjective intoxication was low. In the current study, we aimed to investigate the acute effects of JWH-018 on several cognitive and psychomotor tasks in participants who are demonstrating representative levels of acute intoxication. METHODS: 24 healthy cannabis-experienced participants took part in this placebo-controlled, cross-over study. Participants inhaled the vapor of 75 µg JWH-018/kg body weight and were given a booster dose if needed to induce a minimum level of subjective high. They were subsequently monitored for 4 h, during which psychomotor and cognitive performance, vital signs, and subjective experience were measured, and serum concentrations were determined. RESULTS: Maximum subjective high (average 64%) was reached 30 min after administration of JWH-018, while the maximum blood concentration was shown after 5 min (8 ng/mL). JWH-018 impaired motor coordination (CTT), attention (DAT and SST), memory (SMT), it lowered speed-accuracy efficiency (MFFT) and slowed down response speed (DAT). CONCLUSION: In accordance with our previous studies, we demonstrated acute psychomotor and cognitive effects of a relatively low dose of JWH-018.

New/emerging psychoactive substances and associated psychopathological consequences.

BACKGROUND: The present paper provides an updated review of both the large number of new/novel/emerging psychoactive substances (NPS) and their associated psychopathological consequences. Focus was here given on identification of those NPS being commented in specialised online sources and the related short-/long-term psychopathological and medical ill-health effects. METHODS: NPS have been identified through an innovative crawling/navigating software, called the 'NPS.Finder®', created in order to facilitate the process of early recognition of NPS online. A range of information regarding NPS, including chemical and street names; chemical formula; three-dimensional image and anecdotally reported clinical/psychoactive effects, were here made available. RESULTS: Using the 'NPS.Finder®' approach, a few thousand NPS were here preliminarily identified, a number which is about 4-fold higher than those figures suggested by European and international drug agencies. NPS most commonly associated with the onset of psychopathological consequences included here synthetic cannabinoids/cannabimimetics; new synthetic opioids; ketamine-like dissociatives; novel stimulants; novel psychedelics and several prescription and over-the-counter medicines. CONCLUSIONS: The ever-increasing changes in terms of recreational psychotropics' availability represent a relatively new challenge for psychiatry, as the pharmacodynamics and pharmacokinetics of many NPS have not been thoroughly understood. Health/mental health professionals should be informed about the range of NPS; their intake modalities; their psychoactive sought-after effects; the idiosyncratic psychotropics' combinations and finally, their medical and psychopathological risks.

How Motivations for Using Buprenorphine Products Differ From Using Opioid Analgesics: Evidence from an Observational Study of Internet Discussions Among Recreational Users.

BACKGROUND: Opioid use disorder (OUD) poses medical and societal concerns. Although most individuals with OUD in the United States are not in drug abuse treatment, buprenorphine is considered a safe and effective OUD treatment, which reduces illicit opioid use, mortality, and other drug-related harms. However, as buprenorphine prescriptions increase, so does evidence of misused, abused, or diverted buprenorphine. Users' motivations for extratreatment use of buprenorphine (ie, misuse or abuse of one's own prescription or use of diverted medication) may be different from the motivations involved in analgesic opioid products. Previous research is based on small sample sizes and use surveys, and none directly compare the motivations for using buprenorphine products (ie, tablet or film) with other opioid products having known abuse potential. OBJECTIVE: The aim of the study was to describe and compare the motivation-to-use buprenorphine products, including buprenorphine/naloxone (BNX) sublingual film and oxycodone extended-release (ER), as discussed in online forums. METHODS: Web-based posts from 2012 to 2016 were collected from online forums using the Web Informed Services internet monitoring archive. A random sample of posts was coded for motivation to use. These posts were coded into the following motivation categories: (1) use to avoid withdrawal, (2) pain relief, (3) tapering from other drugs, (4) opioid addiction treatment, (5) recreational use (ie, to get high), and (6) other use. Oxycodone ER, an opioid analgesic with known abuse potential, was selected as a comparator. RESULTS: Among all posts, 0.81% (30,576/3,788,922) discussed motivation to use one of the target products. The examination of query-selected posts revealed significantly greater discussion of buprenorphine products than oxycodone ER (P<.001). The posts mentioning buprenorphine products were more likely than oxycodone ER to discuss treatment for OUD, tapering down use, and/or withdrawal management (P<.001). Buprenorphine-related posts discussed recreational use (375/1020, 36.76%), although much less often than in oxycodone ER posts (425/508, 83.7%). Despite some differences, the overall pattern of motivation to use was similar for BNX sublingual film and other buprenorphine products. CONCLUSIONS: An analysis of spontaneous, Web-based discussion among recreational substance users who post on online drug forums supports the contention that motivation-to-use patterns associated with buprenorphine products are different from those reported for oxycodone ER. Although the findings presented here are not expected to reflect the actual use of the target products, they may represent the interests and motivations of those posting on the online forums. Buprenorphine-related posts were more likely to discuss treatment for OUD, tapering, and withdrawal management than oxycodone ER. Although the findings are consistent with a purported link between the limited availability of medication-assisted therapies for substance use disorders and use of diverted buprenorphine products for self-treatment, recreational use was a motivation expressed in more than one-third of buprenorphine posts.

Chemsex drugs on the rise: a longitudinal analysis of the Swiss HIV Cohort Study from 2007 to 2017.

OBJECTIVES: Chemsex refers to the use of sex-enhancing drugs among men who have sex with men (MSM) in combination with specific sexual and social behaviours. Longitudinal data on this development and the associated health risks are scarce. METHODS: Data on all recreational drugs reported in the Swiss HIV Cohort Study (SHCS) from 2007 to 2017 were collected. Drug use was analysed longitudinally for all drug classes. In addition, potential associations between patient characteristics and the consumption of methamphetamine, γ-hydroxybutric acid/γ-butyrolactone (GHB/GBL), 3,4-methylenedioxymethamphetamine (MDMA/XTC), cocaine and amphetamine were analysed. RESULTS: We analysed 166 167 follow-up entries for 12 527 SHCS participants, including 7101 free text field entries containing information about recreational drugs other than cannabis, cocaine and heroin. Overall, we observed a stable percentage (9.0%) of recreational drug use (excluding cannabis, amyl nitrite and prescription drugs). For MSM, however, there was an increase in overall drug use from 8.8% in 2007 to 13.8% in 2017, with particularly large increases for methamphetamine (from 0.2 to 2.4%; P < 0.001) and GHB/GBL (from 1.0 to 3.4%; P < 0.001). The use of each of the potentially sex-enhancing drugs methamphetamine, GHB/GBL, cocaine, XTC/MDMA and amphetamine was significantly associated with condomless sex with nonsteady partners, and higher prevalences of depression, syphilis and hepatitis C. CONCLUSIONS: The significant increase in the use of chemsex drugs among MSM in the SHCS and the strong association with coinfections and depression highlights the need for harm reduction programmes tailored to MSM. According to our results, improving knowledge about recreational drugs is important for all health care professionals working with people living with HIV.
