I admire your ability to stay the course even though your friends choose a different one. I say different rather than "bad" because IMO they are just doing what some guys do for fun. The truth is that booze and weed will not help your health. A modest amount of alcohol can be beneficial according to some studies, but we're talking like one or two drinks. If you're into weight training at all, neither will help with that either.

Bottom line - you should do what's right for you. If you have survived this long without drinking or smoking, why start now? Anyway, you'll be the one who can outrun, outlift, and out think your friends for it!
