Alcohol and substance use among Japanese high school students.

In the first large-scale survey on the use of alcohol and tobacco and the inhalation of paint thinner by Japanese high school students, a higher percentage of respondents reported past or regular use of these substances than in a 1978 survey. The survey was conducted in 44 high schools. The 14,438 respondents (ages 15-18 years) represented 9 of Japan's 47 geographically distinct urban and rural prefectures. Most (76%) reported that they had consumed alcohol at some time, and 50% reported drinking on a regular basis. Alcohol consumption, drinking partners, and motivation for drinking were compared by student gender, geographic region, and years of education. Fewer students reported smoking cigarettes: 32% had smoked at some time, and 14% smoked regularly. Inhalation of paint thinner was rare: 3% had purposely inhaled it, and 1% had abused it. A significant percentage of the alcohol drinkers also used tobacco and/or thinner, a tendency that was the same despite differences in gender, grade in high school, and urban or rural geographic region. A tendency toward polysubstance use was evident among these high school students.
