I used to be stoned all day and get drunk every night. No moderation with either. Gave them up. I rarely use opioids, but I find them very stimulating. Heroin will keep me up all night. Never found it to be addicting. I'm wired a little differently when it comes to that one. We're not all the same.  

 I would say good whisky is my only vice, the other stuff is not worth it.. I tried.
