I drink mainly for one reason: It's fucking delicious. Beer, wine, bourbon . . . if you find the right one you will get a lot of enjoyment out of it. Most people stop at crappy beer and never move on from that, thinking somehow you've tasted one booze you've tasted them all. Couldn't be further from the truth. To compare crappy Budweiser pilsner to a deep, rich porter is a crime against humanity.
I drink pretty much every day. However I rarely get drunk . . . usually only at weddings and special occasions. Really, getting drunk is often an annoyance for me . . . it means I have to slow down consuming my delicious beverages. Though the initial relaxing feeling is welcome.
Smoking is just plain addictive. The nicotine and the oral fixation. I don't smoke, but if it were cheaper, smelled better, and had no health side effects I'd certainly smoke. It's fun. That's why from time to time I'll go to a hooka lounge where they have flavored tobacco that is run through a water filter that removes most of the carcinigans.
And drugs? Well they are also addictive. Well, pot is only mildly addictive, from what I can tell. There does seem to be some negative health risks associated with it, but these seem to be on the less serious end. If you want info on the negative side effects of pot, watch this video:

I've taken cocain on a daily basis for years at a time. Of course, it was legally prescribed to me and was called Ritalin or Aderol (yes, those are basically legalized cocain).
Obviously, things like heroin, crack, meth . . . these things can destroy you quickly, and leave you a shell of your former self and should be avoided at all costs. Those that want to apply it to ALL drugs are going to cause WAY more damage than they are preventing. If you tell kids, like I was told by a police officer from the D.A.R.E. program, that a single marijuana cigarette will cause you to lose your teeth and hair, and basically destroy your life, and you grow up and find that ISN'T the case . . . well why should I believe them when they say heroin is bad?
Luckily, never tried heroin.
Well I've gotten off topic a bit. I'll close with this though, as an explanation of why you shouldn't shy away from all of these substances. There was a man who decided to give up smoking, drinking, and women. He had a very long life, right up until the moment he killed himself.
