I do both, and I have to say alcohol. I used to actually want to get stoned more, now I often turn it down, just because I find it boring. Sure, if I'm with a bunch of friends, it can be fun, but it depends on the situation and who you're with. Pot just makes you want to go to sleep. Not right away, but it will. Pot for me is the kind of thing you do, when you're with a few friends and the only thing to do is watch tv. For me, its not a party drug... more of a "lets just sit here and watch tv, because its slightly more entertaining than watching tv sober drug".
I also never buy pot, just because well... its a waste of money. I buy alcohol, but not pot. I might take it, if its offered, but other than that, I'm not going out of my way to get it.
Oh.. -brain storm-. Lol. Actually.. if you cook pot, and make brownies or something, that's a good use for it. The high is a lot better, and longer, and well... you can give them to anyone. I actually would go out and buy pot, to make brownies. Not something I'd do often, but just now and then. I find eating it is a lot better. Also, people tend to be a lot more willing to try it, if its in food form. But despite this, it still is a rather boring drug, no matter what form.
I don't see how people can smoke it everyday. If i'm stoned for a couple days in a row, I get annoyed, and want to be sober. I don't know why, but it does that to me. I guess it depends on your personality, but I can safely say right now, I'll never became a daily smoker.
So in conclusion.. I choose alcohol, unless maybe you have brownies or cookies, or something of the sort. Depends entirely on the situation. There are better drugs.
