I enjoy sex after a couple of beers and a spliff.
In moderation and provided you don't get totally off your face, I see nothing wrong.
Relaxes me and lowers some inhibitions. I seem to last a lot longer after a smoke of pot too, so an added bonus.
Svengali, I really enjoy your posts, but I think you're a little naive to think that some of the best music in the world was not produced, created and performed under the influence of drugs. Whilst the Beatles may have said what you quoted once, they have also openly admitted (numerous times) the significant role drugs played in creating their music (specifically LSD and pot).
The same can be said (and openly admitted by): The Beach Boys, The Doors, Jimi Hendrix, Lada Gaga, Frank Zappa, Bob Marley
, The Rolling Stones, INXS etc etc etc... Lot of dead musicians in that small list - hey I didn't say it was good for you !!
