Being pressured in weed?

First of all, I'm 14.Rrecently I've been seeing all of my friends try drugs, specifically weed, and some of them have done it a second time. Before this, i was sure i was gonna try weed, but now i don want to do it just because peer pressure will force me to. If the situation ever arises, should I? (by the way, i was in this situation once, but it was easy enough to say "No, thanks" but i was still called a pus*y :/)
