I can't drink beer anymore. This thread is depressing!
But to answer the question, I don't think one is worse than the other. If you have an addictive personality, you are going to find a poison to overindulge in one way or another. Blame the user, not the substance.
Personally I miss beer because I didn't get hangovers with it, but man that stuff makes you feel bloated and gassy!
With liquor, I have to be careful because it's easier to overdo it and I end up hating life the next day. My tolerance is pretty low, especially now.
Weed...no problem. I don't indulge all that often, but when I do I feel fine after the fact. Me likey.
