Screening for problem or dependent cannabis use

Five EU countries - France, Germany, the Netherlands, Poland and Portugal - have recently started to incorporate brief scales into their population surveys to measure dependence or problem use of the drug cannabis. The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) has recommended that methodological studies be drawn up to better understand the results generated by the new scales implemented in these surveys. The studies would ideally lead to a common European model for monitoring problem cannabis use across EU Member States.
