Mushroom question

Ok... so I have been told a couple things about mushrooms, and I am always a skeptic of any knowledge about drugs I pick up from my stoner friends lol, so here are my questions... Is it true that mushrooms leave the body and do not show up on drug tests after 24 hours? Also, I have been told by many people that eating an eighth or so of mushrooms will help clear other drugs out of the body and therefore help me pass a piss test. The logic apparently is that "frying" means that shrooms basically cook all the poisons in the body. I smoke pot pretty often, but I am in some legal trouble, and am gonna have to start pissing in a cup soon, so I need to quit smoking soon, but if the mushrooms I am picking up tonight will make me able to pass a piss test, then I'll save em, and keep smoking right up until the night before court... This might be a dumb question, but I gotta ask anyway. Thanks for the help!

If youre in legal trouble continuing to smoke is not the way to go. One of my good friends got a possession charge and ended up dropping positive on his LAST probation meeting. He has to go to AA three times a week for six months and has two more years probation. I know thats completely off topic from what youre asking, but its just my opinion.

I am gonna quit once I start probation, but I don't have court until the 16th, so I have a little while before I actually have to start tests.
