The current Flash Eurobarometer on “Youth attitudes on drugs” (No 330), requested by Directorate-General Justice, builds on these earlier surveys in order to measure the trend in attitudes of this target group towards drugs. In response to recent developments in the EU drug market, in the current survey, young people were also asked about their experiences with and attitudes towards new substances that imitate the effects of illicit drugs, so-called new psychoactive substances or “legal highs”.
