Its good advice powder coke isn't that addictive. It just sniffs a lot better than any of that shit. If there was a huge bust and he couldn't get any blow I'm sure OP would be fine with some addys if he was goin out drinkin and just needed a pick me up. (I have never done rits/addys either I'm not a bum I just bought yayo but its similar.) OP should only do mad coke if he sells that shit, or chills with people who always have it and just throws down 20 on some when niggas are doing it. I'd reccomend selling it by the way and getting that paper. Selling drugs during college is cool. Once you hit 22-23 selling drugs stops being cool but up until then its mad chill go for it and don't deal with fuck niggas and you'll be ok. The best way to sell drugs is to have the connect and get the bulk and have 1-2 close friends you can front shit to and have them sell small bags to people so you don't have to get mad phone calls.
Cigs are mad easy to quit if you just always have weed and a oney on you and rip buds whenever you want a smoke. Coke similar. It aint opiates.
Thing with me and coke is I like the high more when I'd do it somewhat regularly. If I blew a monster rail now I'd get all emotional and fucked up and shit. So I don't like it that much. I like Oxys (when they were around) but I don't want to be a junkie so I don't touch that shit cause its such a bomb high.
