Does cognitive behavioral therapy for anxiety disorders assist the discontinuation of benzodiazepines among patients with anxiety disorders? A systematic review and meta-analysis.

Long-term use of benzodiazepines (BZD) is not recommended for the treatment of anxiety disorders. Cognitive behavioral therapy (CBT) is an effective treatment option for discontinuation of BZD in patients with anxiety disorders. This systematic review and meta-analysis sought to clarify whether CBT is effective for discontinuing BZD anxiolytics in patients with anxiety disorders. This study was preregistered with PROSPERO (registration number: CRD42019125263). A literature search of major electronic databases was conducted in December 2018. Three randomized controlled trials were included in this review, and meta-analyses were performed. The proportion of discontinuing BZD anxiolytics was significantly higher in the CBT plus gradual tapering group than in the gradual tapering alone group, both in the short term (3 months after allocation; number needed to treat: 3.2, 95% confidence interval [CI]: 2.1 to 7.1; risk ratio: 1.96, 95%CI: 1.29 to 2.98, P = 0.002, three studies) and long term (6 to 12 months after allocation; number needed to treat: 2.8, 95%CI: 1.9 to 5.3; risk ratio: 2.16, 95%CI: 1.41 to 3.32, P = 0.0004, three studies). CBT may be effective for discontinuing BZD anxiolytics, both in the short term and in the long term after the allocation. Further studies with larger sample sizes are necessary to draw definitive conclusions regarding the efficacy and safety of CBT for discontinuing BZD anxiolytics in patients with anxiety disorders.

Gender Differences in Triggers of Stimulant Use Based on the National Survey of Prisoners in Japan.

BACKGROUND: There are a few studies on gender differences in terms of reasons and motives for methamphetamine use. Purpose/Objectives: To examine gender differences in triggers of methamphetamine use Methods: We provided a questionnaire survey to 699 inmates who were incarcerated because of violation of the Stimulants Control Act. Results: The results of DAST-20 (the severity of drug dependence) moderately correlated with the applicable numbers of the 37 situational triggers and 34 emotional triggers for stimulant use, respectively. Regarding gender differences, items including "when having sex" [46.3% (men) vs. 25.3% (women)], "when I have some money" (39.4% vs. 25.3%), and "after getting paid from work" (22.1% vs. 11.4%) were applicable in a significantly higher proportion in males (p < 0.001 and p = 0.008, respectively), whereas items including "worried about the body shape" (3.5% vs. 31.2%) and "after quarreling with someone" (11.7% vs. 29.1%) were applicable in a significantly higher proportion in females (p < 0.001 for both comparisons). Further, most trigger (emotions) items that exhibited gender differences were significantly higher in females. Many females answered that they had used drugs to relieve discomfort symptoms associated with menstrual periods. Conclusions/Importance: Thus, the awareness of important factors including learning how to deal with negative emotions (e.g. depression), repairing self-image, and recognizing physical and emotional changes associated with the menstrual cycle is helpful in providing proper care and treatment of drug addiction in females.

Parental drinking according to parental composition and adolescent binge drinking: findings from a nationwide high school survey in Japan.

BACKGROUND: Alcohol problems in parents have been revealed to affect adolescent alcohol misuse. However, few studies examine the effects of parental drinking on adolescent risky drinking (including binge drinking) in the general population. In particular, previous study findings are inconsistent regarding the influence of parental drinking according to parental composition. In this study, we aimed to examine the relationship between parental drinking, according to parental composition, and binge drinking among high school students in Japan. METHODS: We performed a secondary analysis of the Nationwide High School Survey on Drug Use and Lifestyle 2018, Japan. A total of 46,848 valid surveys from high school students of 78 schools were included for analysis. Logistic regression analysis with a generalized linear mixed model was conducted with binge drinking as the dependent variable and "parental drinking according to parental composition" (e.g., father's drinking, mother's drinking, father's absence, mother's absence, both parents drinking, and neither parent at home) as the independent variable, after adjusting with covariates. Binge drinking was defined as five or more alcoholic drinks for male adolescents or four or more alcoholic drinks for females on the same occasion within two hours. RESULTS: In the fully adjusted models, adolescents whose mothers drink (adjusted odds ratio (AOR): 1.50, 95% confidence interval (CI): 1.06-2.12) were significantly associated with adolescent binge drinking. This risk was significantly higher among students with neither parent living at home (AOR: 4.35, 95% CI: 2.10-9.02). CONCLUSION: Parental drinking and absence do affect adolescent binge drinking; our findings show that adolescents are more likely to engage in binge drinking if their mothers drink or if they are not living with either parent. Therefore, it is important to engage parents and non-parental family members in future programs and interventions to prevent adolescent binge drinking.

Survey design and outcome measures to evaluate the effectiveness of relapse prevention guidance for drug-dependent inmates in-Japan: A review.

PURPOSE: . In the last-decade, the treatment of drug offenders in Japanese prisons has changed from severe punishment to a therapeutic approach. This study aimed to review studies that evaluated the effectiveness of relapse prevention guidance for drug- dependent inmates in Japan. METHODS: We searched three databases: Ichushi; the Japanese correctional library database; and- PubMed. The inclusion criteria were: 1) the guidance was conducted in prisons in Japan; 2) the participants were Japanese adult inmates; 3) the evaluations were reported in quanti- tative investigations and original articles in Ichushi and PubMed; and, 4) the evaluations were reported in quantitative investigations in the Japanese correctional library database. RESULTS: In total, we identified 13 studies. Three studies.used comparison groups, and two studies included follow-up after the inmates' : release. Two studies-used recidivism and one used treatment persistence as behavioral outcomes. Almost all of the studies used psychological scales. Self-efficacy measures were the most commonly used, and the second most common scale was the Stage of Change Readiness and Treatment Eagerness Scale (SOCRATES). CONCLUSION: Our findings indicate that SOCRATES is the most useful psychological outcome scale in assessing the effectiveness of. relapse prevention guidance for drug offenders in Japan. However, evidence is lacking, as most studies were before-and-after studies that only assessed psychological outcomes. More follow-up studies after release that include comparison groups and investigate behavioral outcomes are needed.

Clinical behavior of Japanese community pharmacists for preventing prescription drug overdose.

AIM: Prescription drug abuse, including benzodiazepines, is a growing health problem in Japan. This study examined the community pharmacist's clinical behavior regarding patients who overdose on prescribed drugs, and explored the possibility of overdose prevention by community pharmacists. METHODS: We surveyed all registered community pharmacies with dispensing functions (n = 1867) in the Saitama Pharmaceutical Association. An anonymous self-administered questionnaire was mailed to each pharmacy. Respondents were asked about clinical behavior such as medication counseling and referral to the prescriber if prescription drug overdose was identified. RESULTS: Among respondents, 26% of community pharmacists reported clinical experience of working with patients who overdosed on prescribed drugs in the previous year. Half of respondents evaluated their practice such as medication counseling and referral to the prescriber as 'good'. On multivariate analysis, a 'poor' self-evaluation of referral to the prescriber was significantly associated with the following perceptions: 'insufficient confidence in communication with prescribers' (odds ratio [OR], 2.7; 95% confidence interval [95%CI]: 1.4-5.3), and 'to avoid trouble with prescribers' (OR, 1.7; 95%CI: 1.0-2.7). CONCLUSION: Japanese community pharmacists could prevent prescription drug abuse in their practice, but the pharmacists who have insufficient confidence in communication with prescribers and who are afraid of trouble with a prescriber, reported poor self-evaluation for referral to the prescribers. All prescribers should understand the importance of referral by community pharmacists, to assist community pharmacists in playing a critical role in prevention of prescription drug abuse.

[Reliability and validity of the Japanese version of the DAST-20].

OBJECTIVE: Assessing the degree of problems related to drug abuse is important in each treatment setting. The Drug Abuse Screening Test-20 (DAST-20) is a brief, simple 20-item instrument to measure the degree of problems related to drug use. The objective of the present study is to examine the reliability and validity of the Japanese version of the DAST-20. METHODS: We translated the DAST-20 into Japanese using back translation. The anonymous self-administered questionnaire was completed by 310 drug users at the Drug Addiction Rehabilitation Centers (DARC group, n = 113) and at HIV/AIDS regional hospitals (HIV group, n = 197) in Japan. RESULTS: The average DAST-20 score was 7.6 (DARC group = 14.7, HIV group = 2.8). Each item score was highly correlated with the total score (r = 0.45-0.88). A high internal consistency (Cronbach's α = 0.95) was observed (men = 0.95, women = 0.84). Overall test-retest reliability was 0.86 (men = 0.85, women = 0.90). The total DAST-20 score was strongly positively correlated with the Severity of Dependence Scale-J score (r = 0.85), but moderately positively correlated with the Alcohol Use Disorders Identification Test score (r = 0.41). In addition, confirmatory factor analysis indicated an acceptable fit to the data (goodness-of-fit index [GFI] = 0.893, adjusted goodness-of-fit index [AGFI] = 0.854, comparative fit index [CFI] = 0.948, root mean square residual [RMR] = 0.008, root mean square error of approximation [RMSEA] = 0.073). CONCLUSION: Our results clearly suggest that the Japanese version of the DAST-20 has sufficient internal consistency and acceptable levels of concurrent validity and construct validity.

[Kiken drugs: current status of abuse among youth in the nightlife areas of Tokyo].

The abuse of "Kiken drugs," including synthetic cannabinoids, is a serious and growing social problem in Japan. Kiken drugs is the general term for novel psychoactive substances that have not been designated as illegal by Japanese law. The aim of this article is to describe the current status of the abuse of Kiken drugs by youth in the nightlife areas of Tokyo. An anonymous field-based survey was conducted using laptop computers at four dance parties in Tokyo, Japan. The questionnaires were completed by 307(44% female, mean age 30.9 years) young adults at the dance parties. Among the survey participants, 24.4% reported Kiken drug use (herbs 22.8%, powders 7.2%, and liquids 3.3%) in their lifetime. The primary reasons for Kiken drug use were peer pressure (37.3%), and avoiding penalties for possession of illegal drugs under Japanese laws (28.0%). In addition, 61.3% reported obtaining Kiken drugs from close friends. Our results clearly suggest that young adults at dance parties have a higher lifetime prevalence of Kiken drug use than the Japanese general population (0.4% reported in 2013). As the social stigma associated with drug use is extremely high in Japan, avoiding illegal drugs prohibited by law by using easily available Kiken drugs may be more socially acceptable among youth in the nightlife areas.

A longitudinal study of women's memories of their childbirth experiences at five years postpartum.

BACKGROUND: Few studies have investigated whether women can accurately recall their birthing experiences after a long period. We investigated the consistency of women's memories of their childbirth experiences between those at a few days postpartum and 5 years later. METHODS: This prospective cohort study comprised 1,168 women who delivered at a maternity hospital and four maternity homes in Japan between May 2002 and August 2003. Data were collected using structured interviews and transcriptions from medical records. The childbirth experience was assessed using the Childbirth Experience Scale (CBE-Scale) at a few days postpartum and 5 years later. RESULTS: We obtained 584 (50.0%) valid responses from women who completed the survey at a few days postpartum and 5 years later. Significant differences were observed in 16 out of 18 items on the CBE-Scale when responses were compared at both time points. Women who answered "yes" to any item on the CBE-Scale at the baseline survey tended to demonstrate a more precise recollection for that item 5 years after childbirth than those who answered "no" for the corresponding item. CONCLUSIONS: We conclude that women remember their childbirth experience clearly at 5 years after the childbirth.

Situational factors affecting abstinence from drugs: Panel data analysis of patients with drug use disorders in residential drug use treatment.

Aim: To identify situational factors that can predict drug abstention in patients with drug use disorders undergoing residential drug use treatment. Methods: Patients with drug use disorders admitted to drug addiction rehabilitation centers (DARCs) in 2016 were involved in this study. Longitudinal panel data were used, with eight follow-up surveys over 6 years, approximately every 6 months. Of the 2752 samples from the eight follow-up surveys, 2293 were analyzed as the complete panel data set. The primary outcome was drug abstention for approximately 6 months. The influences of situational factors during this period on the primary outcome were also assessed using a generalized linear mixed model in which inter-individual differences were controlled as variable effects. Results: The use of residential DARCs positively influenced the primary outcome (adjusted odds ratio [AOR] 3.33, 95% confidence interval [CI] 1.79-6.21) when compared to no DARC usage. The cessation of drinking also positively affected the primary outcome (AOR 3.10, 95% CI 1.79-4.62), while employment status (AOR 2.22, 95% CI 1.12-4.41) and the cessation of drinking (AOR 4.92, 95% CI 2.77-8.72) positively impacted the primary outcomes of patients not using DARCs. Conclusion: The use of residential DARCs and the cessation of drinking positively affected drug abstention rates. Employment and the cessation of drinking for patients who were not using the DARCs also had a positive effect. This information will aid in the development of social recovery strategies for people with drug use disorders.

Comparison of patients with benzodiazepine receptor agonist-related psychiatric disorders and over-the-counter drug-related psychiatric disorders before and after the COVID-19 pandemic: Changes in psychosocial characteristics and types of abused drugs.

AIM: To investigate changes in the clinical characteristics of patients who abused benzodiazepine receptor agonists (BZRA) or over-the-counter (OTC) drugs before and after COVID-19 based on the 2018 and 2022 data of the "Nationwide Psychiatric Hospital (NPH) Survey on Drug-related Psychiatric Disorders." METHOD: A total of 446 and 155 cases, and 435 and 273 cases, who mainly abused BZRAs or OTC drugs, respectively, were extracted from the database of the two NPH Surveys. Demographic variables, education, employment, criminal record, drug use during the previous year, psychiatric diagnosis, and types of abused drugs were compared between 2018 and 2022. RESULT: A comparison of BZRA abusers revealed a decreased number of users during the previous year and an increase in the comorbidity rate of other disorders (F3 and F4 in ICD-10) in 2022. Etizolam, flunitrazepam, triazolam, and zolpidem were used most in both years, with an increase in zolpidem and a decrease in triazolam in 2022. A comparison of OTC drug abusers revealed a higher proportion of women and young patients in 2022. An increase in the comorbidity rate of F3 and F9 and a significant increase in the use of dextromethorphan products were observed in 2022, although codeine products were in the majority in both years. CONCLUSION: By comparing NPH Surveys before and after the COVID-19 pandemic, both BZRA abusers and OTC drug abusers present complex pathologies, requiring tailor-made treatment. The younger OTC drug abusers were particularly evident among women, and the abuse of dextromethorphan-containing OTC drugs has increased alarmingly.

Ecstasy (3, 4-methylenedioxymethamphetamine) use among Japanese rave population.

AIMS: The aim of this study was to examine the prevalence of 3, 4-methylenedioxymethamphetamine (MDMA) use and to identify characteristics of MDMA users among rave attendees in Japan. This is the first rave-population study focusing on MDMA use in Japan. METHODS: The anonymous self-administrative questionnaire was conducted using laptop computers at four rave parties at three different venues in Tokyo, Japan. Participants were asked about lifetime use of MDMA and other club drug use, characteristics of rave attendance, and their demographics. RESULTS: Questionnaires were completed by 300 rave attendees (47.3% female), 68.3% of whom were aged 20-29 years, and 92.3% of whom had completed high school. Among the participants, 8.0% reported MDMA use. Compared with 'non-drug controls' (the participants who had never used any illicit drugs), MDMA users were significantly more likely to be 30-39-year-old men. In addition, compared with 'cannabis users' (non-MDMA users who had used cannabis), MDMA users were significantly more likely to use other drugs and reported more adverse health effects due to 'polydrug use'. Furthermore, MDMA users were significantly more likely to go to raves and preferred smaller venues. CONCLUSIONS: Our results clearly suggest that rave attendees have a higher lifetime prevalence of MDMA use than the Japanese general population (0.2% reported in 2007). MDMA users are deeply involved in rave parties, and MDMA use may have high potential to generate close relationships among rave attendees. Therefore, MDMA users may have more opportunities to access MDMA than cannabis users and non-drug controls.

Sex differences in the characteristics of stimulant offenders with a history of substance use disorder treatment.

We analyzed the results of a nationwide questionnaire administered to 699 stimulant offenders and examined sex differences in the association between various psychosocial problems and treatment history for substance use disorder. Based on their attributes, we predominantly evaluated the treatment and support provided to women with substance use disorder. The rates of childhood (before the age of 18) traumatic experiences (physical, psychological, and sexual abuse and neglect) and lifetime intimate partner violence were significantly higher in women than in men. The history of treatment for substance use disorder was also significantly higher in women than in men, at 15.8% for men and 42.4% for women [χ2 (1) = 41.223, p < 0.001]. Logistic regression analysis was performed using the treatment history of substance use disorder as the dependent variable. The results showed that treatment history was significantly associated with the total drug abuse screening test-20 score and suicidal ideation in men and with survivors of child abuse and eating disorders in women. A comprehensive assessment is required for several issues, such as child abuse, domestic violence, trauma symptoms, eating disorders, and drug problems. Moreover, an integrated treatment for substance use disorder, trauma, and eating disorders is required for female stimulant offenders.

Prevention of overlapping prescriptions of psychotropic drugs by community pharmacists.

The nonmedical use or abuse of prescription drugs, including psychotropic medicines, is a growing health problem in Japan. Patient access to psychotropic drugs, specifically from the oversupply of medications due to overlapping prescriptions, may increase the risk of drug abuse and dependence. However, very little is known about such overlapping prescriptions. Today, the dispensing of prescriptions is generally moving from inside to outside of hospitals, with psychotropic drugs mainly dispensed at community pharmacies. In this study, we used health insurance claims (i.e., receipts) for dispensing as the main source of information in an investigation of overlapping prescriptions of psychotropic drugs. A total of 119 patients were found to have received overlapping prescriptions, as identified by community pharmacists who were members of the Saitama Pharmaceutical Association, using patient medication records, followed by medication counseling and prescription notes for the patient. According to our findings, the most frequently overlapping medication was etizolam. Etizolam can be prescribed for more than 30 days since it is not regulated under Japanese law as a "psychotropic drug." Generally, when a drug can be prescribed for a greater number of days, it increases the likelihood of an overlapping prescription during the same period. As a result, the long-term prescription of etizolam increases the risk of overlapping prescriptions. We also found that the patients who received overlapping prescriptions of etizolam were mostly elderly and the most common pattern was prescription from both internal medicine and orthopedics physicians. Etizolam has wide range of indications that are covered by health insurance. Our results suggest that patients who received overlapping prescriptions of etizolam may receive prescriptions from different prescribers for different purposes. Therefore, it may be appropriate to regulate etizolam as a "psychotropic drug" under Japanese law, thus setting a limit on the period for which it can be prescribed in order to help prevent long-term and overlapping prescriptions.

[A study on clinical features of patients with benzodiazepines use disorder (BZsUD), and characteristics of psychiatric treatments which may cause BZsUD].

BACKGROUND AND AIMS: The aims of present study are to clarify the clinical features of patients with benzodiazepine use disorder (BZsUD), and to examine the characteristics of psychiatric treatments which may cause BZsUD. METHODS: We conducted a medical chart and interview survey to 87 outpatients with benzodiazepine use disorder, who had consecutively visited the four hospitals, specialized in addiction problems, located in metropolitan area, during a month of December, 2011. RESULTS: Consequently, 88.5% of the patients with BZsUD reported to obtain BZs to be abused from general psychiatric clinics, and 83.9% contracted BZsUD in process of general psychiatric treatment. Among the patients who contracted BZsUD in process of psychiatric treatment, 43.8% were speculated to have the other substance-related disorders such as methamphetamine or alcohol-related disorder at start of the psychiatric treatment. Further, approximately 70% of them reported that surplus BZs were prescribed without consideration of storing drugs, and over 40% also reported that BZs were prescribed without a medical examination. CONCLUSIONS: The findings of the present study may let us to propose the following four measures to be taken for prevention of BZsUD: First, latent substance-related disorders should not be overlooked, second, short-acting and high-potency BZs should not be prescribed if possible, third, storing and abusing BZs should always be considered, and finally, BZs should be prescribed with a medical examination.

Prevalence of adverse childhood experiences and their association with suicidal ideation and non-suicidal self-injury among incarcerated methamphetamine users in Japan.

BACKGROUND: Adverse childhood experiences (ACEs) are distressing and/or traumatic events that occur during childhood that increase the risk of negative health outcomes in adulthood. OBJECTIVE: This study estimated the prevalence of ACEs in a nationwide sample of Japanese methamphetamine users in prison and examined associations among ACEs, suicidal ideation, and non-suicidal self-injury. PARTICIPANTS AND SETTING: Participants were 636 inmates (418 male and 218 female) who were newly incarcerated in Japan for Stimulants Control Act violations. METHODS: First, 699 participants completed an anonymous self-report questionnaire. Of these, 636 participants who did not have any missing responses were included in the analysis. After calculating descriptive statistics, the associations between ACEs and suicidal behaviors were assessed using binary logistic regression analyses. RESULTS: Results showed that 76.1 % of the participants reported at least one ACE before the age of 18, and female participants reported a significantly higher number of adversities than their male counterparts. The most common ACEs were parental death or divorce, followed by psychological abuse. Logistic regression analyses revealed that ACE scores significantly increased the risk of suicidal ideation (SI; adjusted odd ratio [AOR] = 1.18, p < .001) and non-suicidal self-injury (NSSI; AOR = 1.18, p < .001) after controlling for possible confounding variables. CONCLUSIONS: Findings suggest the importance of early prevention and intervention for traumatic experiences, and have implications for the recommendation of gender-responsive, trauma-focused interventions, especially for female inmates in the criminal justice system, to break the intergenerational chain of abuse. Future research directions and treatment are discussed.

Gender Differences in the Relationship between Methamphetamine Use and High-risk Sexual Behavior among Prisoners: A Nationwide, Cross-sectional Survey in Japan.

This study aimed to examine the relationship between methamphetamine (MA) use and high-risk sexual behavior among newly incarcerated prisoners in Japan. We conducted a secondary analysis using cross-sectional survey data, which constituted a nationwide prison sample surveyed between July and November 2017. In total, 699 participants (462 male and 237 female prisoners), who completed the self-administered questionnaire during imprisonment were recruited for the study. The prevalence of high-risk sexual behaviors was as follows: inconsistent condom use (78.4% male, 81.7% female), multiple sexual partners (61.3% male, 41.3% female), history of sexually transmitted diseases (14.1% male, 23.6% female), and trading sex for drugs (15.6% male, 17.7% female). A logistic regression analysis showed that MA use during sex increased the likelihood of high-risk sexual behavior in both male (adjusted odds ratio [AOR] = 5.86; 95% confidence interval [CI] = 3.41-10.07) and female prisoners (AOR = 2.58; 95% CI = 1.33-5.00). Additionally, in female prisoners, a history of sharing MA injection (AOR = 1.60; 95% CI = 1.06-2.42) increased high-risk sexual behavior. Our results indicate that harm reduction programs tailored according to the specific necessities of each gender to reduce high-risk sexual behaviors among MA users should be included in Japanese drug policies.

The relationship between severity of drug problems and perceived interdependence of drug use and sexual intercourse among adult males in drug addiction rehabilitation centers in Japan.

BACKGROUND: Consuming drugs in conjunction with sexual intercourse may shape the perceived interdependence of drug use and sexual intercourse (PIDS). Additionally, the severity of drug problems may have a significant impact on PIDS. However, this relationship remains unverified. Therefore, this study investigates whether the severity of drug problems is associated with PIDS among adult males in drug addiction rehabilitation centers (DARC) in Japan. METHODS: This study was a secondary analysis of the "DARC Follow-Up Study in Japan" conducted by the National Center of Neurology and Psychiatry in 2016, in which participants from 46 facilities completed a self-report questionnaire. A total of 440 males with drug dependence were included in the analysis. We analyzed participants' demographic characteristics, history of sexually transmitted disease diagnoses, and responses to questions related to drug use (e.g., primary drug use and PIDS). Additionally, we measured the severity of drug problems using the Japanese version of the Drug Abuse Screening Test-20 (DAST-20). RESULTS: The median age of the participants was 42 years. The median DAST-20 score was 14.0, the primary drug was methamphetamine (61.4%) and new psychoactive substances (NPS: 13.6%). Multivariate analysis indicated that participants' experiences with unprotected sexual intercourse ("mostly a non-condom user": adjusted odds ratio (AOR) = 4.410), methamphetamine use (AOR = 3.220), new psychoactive substances use (AOR = 2.744), and the DAST-20 score (AOR = 1.093) were associated with PIDS. CONCLUSIONS: This study indicated that the frequency of unprotected sexual intercourse under the influence of drugs, methamphetamine and NPS use were strongly associated with PIDS. The severity of drug problems was also significantly associated with PIDS. It is necessary to develop culturally appropriate treatment programs adapted to the needs of patients who experience strong PIDS.

[Community-based prevention of drug abuse in Japan].

The objective of this article is to review community-based drug abuse prevention and relapse prevention in Japan. Japan has a highly efficient system for the primary prevention of drug abuse; this system includes drug abuse education programs in schools and anti-drug abuse campaigns in communities. On the other hand, relapse prevention activities, such as counseling service at mental health welfare centers, self-help groups for drug addicts, and relapse prevention programs at outpatient clinics, are limited because of zero tolerance policies. Therefore, more relapse prevention activities are required in Japanese communities.

[Hallucinogens].

Hallucinogens are drugs that cause hallucinations, which is distortions in a person s perceptions of reality. Historically they were found in some plants and mushrooms and had been used mostly during religious rituals. Various hallucinogens came to be compounded chemically in the 20th century, and have spread among the young men in West European countries. Also in Japan, use of MDMA, or other hallucinogens is increasing in the young adult and minors. In recent years, Japanese medicine-related law were revised and most hallucinogens came to be treated as illegal drugs, but even now Japanese young men have got hallucinogens through the Internet and dance clubs, and medical and educational staffs and caregivers need to implement early intervention.
