What should I do in this situation about my friends?

I'm Lebanese American and everyone in my community drinks, haves , and does drugs. But, I don't like hanging out with them. I have Non Lebanese friends and they're great. I love my friends, but my parents and siblings don't like that. They say I'm going to marry an arab and be with the people in my community for my whole life so I should be friends with them, and not my American friends. It makes me really sad how my own family is encouraging me to be the drug addicts and not with clean and educated people. What should I do? What should I tell them?
