I'm going to answer this based on the assumption that the question refers to drinking alcohol, which is how it would be interpreted in America.

No; I don't drink at all.  I have never felt any urge to consume any alcoholic products, and I've been fortunate enough to not have had any peer pressure to drink alcohol.

I have a greater motivation for not drinking though -- my career depends on my ability to make the best judgments possible, and the fact is that even the smallest amount of alcohol consumption can result in one's judgement being temporarily impaired.  When I play video poker, I'm usually making a decision in 2 seconds or less as to what is the best play for that hand, out of 32 possibilities.  Making the wrong choice costs me money.  If I were to consume alcohol and play while impaired, I could pile on a lot mistakes very quickly, and the cost of those mistakes would easily be worth a lot more than the "value" of the alcoholic drink(s).

Drinking and gambling don't mix, if you care about your wallet.  Of course, there's also a lot of other activities that drinking doesn't mix well with (most notably driving).
