I think its an age thing, ive done my fair share of dabbling when i was younger, but as you get older you just think "whats the point!?".
I look at people now when im out, you can see that they are wired, and i just think to myself "why do you need to stuff shit up your nose to make you have a good night out!"
Each to there own, just grew out of it years ago and dont see the point.
We can say the same for alcohol though, can't we?
I see your point, but see BOF's post above yours mate.
Drinking is/can be social...drugs never will be.
