@ekaitz_zarraga unfortunately its no surprise to me; 10 years ago there were a lot of "new psychoactive substances" sold to whole EU from UK that got people high and were affordable; they may have led to "anti social behaviour" but weren't even that deadly/unhealthy.
These got banned in 2016, and people went back either to conventional hard drugs and alcohol or inhaling glue/solvents (as these things are too useful to ban outright)
