Mobile prevention projects are adapting to fragmentation of the ‘rave’ culture, so that the target group of young recreational drug users may still be reached, for instance through contact points for every ‘scene’. Among the countries where pill testing existed, the practice has been discontinued in Germany and Portugal. In the Netherlands, pill testing is carried out only in laboratories, and in France the abandonment of on-site pill testing has been proposed. Among the reasons for these changes are the reduced frequency of adulterated pills in western Europe and continuing concerns over the legality of the practice. In the Czech Republic, however, pill testing projects continued and were, in fact, the subject of media debate.
