good post dude. i share the same view when it comes to smoking. why do people smoke? everyone knows the first puff is disgusting, so why keep doing it - strange.
i personally do drink, but not to the point where i will talk like a twat and act like a prat. i enjoy a beer after work or down the pub watching football (soccer). im 22 (so legally 4 years of drinking under my belt - from the uk) and only tried my first glass of red wine a few months ago and yeah, its gross. slowly getting into a nice white wine though. but things like vodka, scotch etc i dont touch.
But i suppose when i do tend to drink quite a bit (birthdays etc), i do act differently, not in a bad way. i begin to come care free to my actions, talking to other people, danceing etc.
