Being "safe on the streets" is what this discussion was about. Drug use is irrelevant to what was being discussed, with user "ResearchCode" claiming that Barcelona is a place where people "are asked to practice war zone vigilance", something they've failed to back up with any kind of sources.

With respect to the drug use, I don't buy that measuring use is a valid proxy for measuring abuse or "disasters" - assuming all use is abuse is a severely puritan value judgement. I'd much rather be around an ecstasy or cannabis user than an alcohol user for example.
