I don't do drugs but I don't necessarily judge those who do... everything in moderation and all that (of course I'm not talking about hardcore addicts or those that hurt other people because of their habit). However, when I was about 16 a couple of my friends took coke in front of me and it really shook me up at the time. It's not nice to see, looks completely unnatural in my opinion and put me off for life to be honest.
