Seems to be the most popular recreational club drug now, judging by the amount of people 'bombing' it in rizlas last time I went out.
None of my friends that have tried it think it's anywhere near as good as proper MDMA or a good pill, but it definitely 'does something'. Someone told me that if you buy pills now, they're very likely to be mephedrone anyway, not E. Don't know if that's true, but if it is, it's probably just better buying the pure stuff anyway, surely? Least you know what you're getting.
