Illegal Drug Use Among Adolescents in Schools and Facilities: 3-Year Surveys in Taiwan.

This study investigated and compared the prevalence of illegal drug use among students and detainees in Taiwan. Stratified sampling of schools in the major cities of Taiwan, including New Taipei City, Taichung City, and Kaohsiung City, was adopted, and surveys were conducted from 2014 to 2017. The sample in the study consists of 2,190 cohort school students and 125 detained juveniles in the Taipei, Taichung, and Kaohsiung Juvenile Detention Houses each year. The response rate is 87% on average. The results show that 1.5% of students and 65.8% of detained juveniles have ever used drugs. From 2014 to 2017, the survey indicates that over 60% of detained juveniles have ever possessed and used drugs. The findings reveal that ketamine and disguised drugs (e.g., cathinone mix with methylamphetamine, 3,4-methylenedioxymethamphetamine, and ketamine) are the most popularly used drugs among Taiwanese adolescents. The findings may deserve further attention in tracking and monitoring the juvenile illicit drug use from a comprehensive national prevalence survey. [ABSTRACT FROM AUTHOR]
