n. A drug formerly used in legitimate markets to treat parasitic worm infections and several forms of cancer, it is now often cut with crack on the streets due to their similarity in appearance. It will also add bulk and weight to powdered cocaine, making it appear more pure.
Dude: Hey, wanna smoke of this crack I just got? Oh shit, this is just some Levamisole.
