Why don't you do some real hallucinogens? DXM is an o-k dissassociative that should only be used if nothing else is available and even then sparingly. It's full of dumb shit that I'm sure is fucking up your liver. Fuck, dxm is for teenagers who can't afford drugs so they steal cough syrup from the pharmacy. You're a big boy now.
N don't tell me you don't know where to find shrooms/acid/dmt/anything else. You said you smoke alot of weed? Ask your dealer if he knows someone. If he doesn;t, ask him if he knows someone that has vicodins or something common like that, then ask the vicodin dude if he knows where to get hallucinogens. Etc. That's how this game works man, gotta ask around.
N really asking about hallucinogens isn't a big deal to most people. If you ask for heroin or crack, they'll probly look at you funny but tripping is pretty mainstream these days.
