Coke, MDMA and E I guess, but I don't really consider those hard. I have friends who are on M and coke more often then they aren't. One friend would do M and coke and then go to his job working city transportation. These are all just as common as weed now. Drugs are only as hard as you let them I guess. Except meth and heroin...that shits crazy.
If I'm going to do anything these days, I stick to edible drugs. Weed cookies are delicious and shrooms are fun once in a while.
