Im trying to help him

My dealer/ best friend just started smoking weed again. Hes only 14 and really depressed due to being dumped by his ex who is now going out with one of his other best friends (she dumped him 4 months ago and hes still down). Well he came to school yesterday hyper and happy. He was like "What would i do without weed?" And "Weed is all I need HAHA THAT RHYMES!" I dont know if this sounds really strange to others but I know him and he does not need weed to make him happy! I dont even think he is happy I think hes fronting and just smoking bud because hes extremely bored and lonely. I was talking to the guy that got high with him and I told him i was concerned about how he was so hyper just by smoking a few bowls the other night. Well he yelled at me and threatend me that if I tried to stop him from selling weed then hed never forget it and might do something bad to me. First, i never fucking said he should stop selling or I was gunna try and stop him. Thats his life, im just a small part in it. So yeah, what should I do bout him? I love him and he means the world to me. I want him to be happy but I dont know how if he doesent try. the guy also said that just because im depressed doesent mean i should be jealous of Corey being happy. That got to me...I am depressed...and now im starting to think maybe thats what im trying to do...I dunno im confused. HELP!

He's a youngin don't worry about it. I don't know any potheads that are hyper off the chain. He's just in a phase......

Don't try to put him down man, remember life is to pursue happiness, don't deny yourself of it.

Im not gunna bring it up with him. He just came back from that guys house...and I dont know how it went since he is on away right now but its not that I dont want him to be happy, I just want him to find happiness from something besides marijuana.
