All I can really say is that it takes time to heal. You are human, and you have feelings, and for that alone, you can't just turn your emotions on and off just like that.
If he would rather be smoking that junk, then you might be better off to leave him too it, unless of course he's just a teen, and still living at home, then you should consider telling his parents, for his health and his future.
Don't do it to be a narc, or to get even, but just as a way to say that you care, and you accept that you shouldn't be with him, especially if he doesn't care for you.
Soon enough you won't think about him like you do now, and you should be out there hanging out with your friends, not sitting around feeling sad about him. Your friends, and your family should be the center of your attention, next thing you know, there will be someone else there who would most likely love to spend time with you, and asking you out, so don't say no o.k. Hope this helps, good luck.
