It's not like psychedelics went extinct or anything. We just had loads of luvverly ecstacy to wash them down with (not that I'm advocating taking class A drugs, drugs are bad, K?)
Seriously though, the whole "second summer of love" thing in the early 90s was an unbelievable time to be a young adult (ok, not necessarily a teenager, feck you LK) mainly because of the effects of MDMA and the amazing bonding experience that gave to anyone who was a part of it. Wouldn't have been anything like that on LSD, shrooms, peyote or whatever. To walk into a rave back then and see a whole room full of hundreds of people, bursting with good vibes, positivity and love was a life-changing experience. For me anyway.
E's are still round now, but the whole vibe has changed completely. When it was all fresh and new, you really felt like you were part of something special and, to an extent, we were.
But don't mind me and my reminiscing. This is way off topic. I might start a new thread about it. Hmmm...
