As someone who has only smoked pot and done a couple things (LSD and shrooms) I will NEVER EVERR IN MY ENTIRE LIFETIME try anything but those 3 things, cigarettes and booze. It's not a gateway drug, you said it yourself he was peer pressured into trying coke. I'll kick my friends in the balls if they try that shit on me. It's 1 thing to smoke weed and life a normal life. Meth, heroin, coke, crack, ect. Those will -blam!- your life up. I mean absolutely destroy your life then they'll kill you. Weed though? No. Weeds fine. Just know what moderation is.
