So take this all with a grain of salt, as if there is one report of something happening, it may have a good chance of ending up in the literature and then on Medscape, but really because it is an oddity, and not at all the norm. OTOH, I've heard more and more reports of the levamisole and I know it to be a fairly widespread problem nowadays. Off topic, who figures these things out??? I mean, who tries snorting levamisole and says "hey this stuff is good!" it's a deworming agent given to animals, who even THOUGHT to try it???
