Drugs/ Turn off or Not?

I just found out recently that the guy I like does drugs. I think it's a HUGE turn off!! His friends that sit next to me in class, all they do is talk about "Hey have to tried the new ___" Holy Sh!t dude I made a bong in lunch!! to each other. One kids a skater and the other kid cuts himself. It's like a major turn off for me because I take care of my body and don't do any sex or drugs. They might like me... O_O (15 Freshman) What do you think of people who do drugs?
