Methamphetamine has so many names. Some call it "meth", others call it "chalk" or "speed". It has different names for its smoked form – crystal, ice, glass, and crank are a few examples. Unlike heroin, which has no medical use, meth is sometimes used for the treatment of attention deficit disorder, narcolepsy, and obesity.

    If I snorted a quarter gram of meth over a three day time period do you think it would be out of my system in 4 days? I was completely clean of all drugs before those three days, weigh about 250 and am quite active.
