"• Despite the lack of empirical data - for health systems in general and information and prevention projects in particular - it is crucial to know about new substances and consumption trends, otherwise there is a high risk of loosing credibility with well-informed users of psychoactive substances. Pill-testing projects can be an important source of information on new substances and consumption trends as they are in closest possible contact with the relevant scenes, more so than other organisations within the prevention system. They have, furthermore, an insight into most substances that are actually being consumed, and know who and where, in which manner, and why these substances are being consumed.
"• Pill-testing interventions have to be part of a global strategy for prevention and harm reduction in recreational settings.
"• By using the information from on-site pill-testing interventions, a national warning system could deepen its data pool in terms of social contexts: who are the people consuming these substances, how, where and why are they consuming these substances in this and that particular way and which information can be passed on to potential consumers in a meaningful and successful manner?
"• Due to the lack and difficulties of evaluation, on one hand there is still no strict scientific proof for the protective impact of on-site pill testing interventions, but on the other hand there is also no scientific evidence to conclude that such interventions would rather promote drug use or might be used by dealers for marketing purposes. Bringing together pieces of evidence is however often a first step for deciding on new intervention models."
