So far, several dozen warnings for drugs that have already been tested are listed on the project website. Laboratory analyses revealed, for example, admixtures of unknown substances, impurities with known substances or too high dosages. In the meantime, the warning rate for the samples submitted varies from 30 per cent to more than 50 per cent, it said. The drugs frequently analysed included ecstasy, pure amphetamine, amphetamine-caffeine mixtures (speed) as well as mephedrone, cocaine, ketamine and LSD.
