Fewer young people in Switzerland are drinking alcohol and smoking tobacco or cannabis. But researchers say a small, high-risk group is drinking heavily and taking more hard drugs. These are the main Swiss findings of the European School Survey on Alcohol and Drugs, which was last conducted four years ago and now compares 43 countries. Here in Switzerland, the survey investigated the drink and drugs habits of more than 7,500 teenagers, aged between 13 and 16. WRS’s Vincent Landon spoke to Gerhard Gmel from the Swiss Institute for the Prevention of Drug and Alcohol Problems—and principal investigator of the survey—and began by asking him to explain the downward trend.
