Our colleagues from Safer Party in Switzerland recently tested an ecstasy tablet which, in addition to MDMA in high doses also Butylon (bk-MBDB) contained. The tested tablet is white and has the "VW" symbol on the front. Butylone falls into the group of research chemicals, which means that there is hardly any information about its effects and possible risks. In addition, interactions can hardly be assessed. The exact description of the tablet and information about the substances can be found at here.

If you have a pill that looks like this and decide to take it despite the health risks, have the tablet analysed beforehand!
