In view of the recent rise in drug consumption, a 3-year longitudinal study of 19-year-old men was conducted to investigate development of consumption behavior. Consumption of cigarettes and alcohol was also considered. The aim was to obtain information about the development of consumption by 19-year-old men (increase, decrease, etc). The follow-up sample consisted of 841 men in the Canton of Zurich who had been selected from a complete survey of men born in 1952. They answered a questionnaire at the age of 19 and again three years later. The results show that drug, cigarette and alcohol show a different development of consumption in the ages between 19 and 22 years. The percentage of drug consumers had decreased from 23.3 percent to 14.8 percent. In approximately 4 percent there is a high risk of dependence in addition to absence of social integration. The percentage of cigarette smokers did not change (approximately 53 percent), but the number of cigarettes smoked per day increased. For alcohol there is a general increase in consumption. For all three substances, heavy consumption at the age of 19 increases the risk of heavy consumption at the age of 22.
鉴于近期药物消费有所增加，对19岁男性进行了一项为期3年的纵向研究，以调查消费行为的发展情况。同时也考虑了香烟和酒精的消费情况。目的是获取有关19岁男性消费发展情况（增加、减少等）的信息。随访样本包括从对1952年出生男性的全面调查中选取的苏黎世州的841名男性。他们在19岁时回答了一份问卷，三年后再次回答。结果表明，在19至22岁之间，药物、香烟和酒精的消费呈现出不同的发展趋势。药物消费者的比例从23.3%降至14.8%。除了缺乏社会融入外，约4%的人有很高的成瘾风险。吸烟者的比例没有变化（约53%），但每天吸烟的数量增加了。酒精消费总体上有所增加。对于所有这三种物质，19岁时的大量消费会增加22岁时大量消费的风险。
