If you've never been part of a drug culture then it's hard to understand.
The memories I have of summers by a fishing lake, relaxing with some smoke and talking crap about random stuff with my buddies, the ritual of rolling and the rights of who gets what.
Other memories of being on holiday with my ex-partner and getting so high that we spent the whole night staring into the sky talking about the cosmos while on a camp site in the country side.
Memories of asking the regular Pizza Hut delivery guy to pick us up some skins from the shop on his way over so we didn't have to go outside, and we could tip him with a joint.
The feeling that the substance gives, the escape from reality, the elevation of stress and a whole host of other reason.
I'm not preaching drugs to people, I would actively discourage anyone from doing such things, they aren't good for people but if anyone reading this has been in my position, as ScouserInExile clearly has, then it will make sense to them.
It's about occasion.
And remember kids, drugs are bad. Really, they are.
