Total opposite for me, smoking destroys my social skills. I feel like I have no reason to be talking to anyone, that I should just leave and read a book or walk in the woods and think. I think it's because being high really makes me realize where I am and what I'm doing for what it IS, and allows me to make a more basic emotional response to it, instead of just going with the flow.

If I'm with a group larger than 3 people I'll usually try to avoid smoking, because I know I'll just realize that I actually am not enjoying myself by being with them.
