Why do you think you would become an alcoholic if you started to drink? I drink for more than 10 years. It happens 2-4 times a months. I never drink alone. Usually, I go out with my friends and then I drink. Sometimes I drive to parties so I cannot drink obviously. What I can say. You are right. Drunk people behave differently, not in a bad way though (I am talking about my friends here). When you are sober among drunk friens it is OK, but you kind of fall out of the company in some way. So I usually drive when I do not want to drink. Otherwise I do not see why I cannot drink and have fun with others.

By the way I do not smoke. This is absolutely useless and harmful to the people around.
