I live in Ireland and drug use seems to be an epidemic. Statics show we are the 4th highest users of cocaine globally and the highest users of cannabis in the EU. It makes sense given that you can't go into a pub without seeing several people sniffing in the toilets or walk the streets without smelling cannabis.
Despite this, our police and courts seem to be very backwards with their attitudes towards drugs and regularly drag people to court for having €5 worth of cannabis as well as threatening them with a conviction if they don't pay 100s of euros to the "poor box" (a charity that the judge chooses). We also don't have any drug testing facilities in general or at festivals. I imagine other Europeans countries are more progressive.
