Methamphetamine can be taken orally, snorted (in powder form), smoked, or injected. Crank, which is administered in a powder form, can be used much in the same way as pure methamphetamine.
Meth is a stimulant that creates incredibly positive, euphoric, and alert feelings over a period of several hours. However, it is also an extremely addictive stimulant.
