Ecstasy pills are becoming stronger and cocaine sold on the streets is more pure, according to a new report by the addiction centre Trimbos Institute. The institute bases its claim on tests carried out on 12,000 drug samples in 2017. The researchers found the amount of MDMA – the active ingredient – in ecstasy pills had gone up from an average 120 milligrams in 2013 to 167 milligrams last year. When it comes to cocaine, in 2014, just 59% of the powder was made up of the actual drug, but this rose to an average of 68% last year.
