How are amphetamines used?
“Amphetamines are most often taken orally with blood levels peaking in one to two hours and effects appearing in 30 minutes and lasting in excess of three hours,” says Wadler. Amphetamines can be injected intravenously or smoked. The smokeable form is a methamphetamine called “Ice,” which is very potent, long-lasting and extremely addictive and illegal in most states.. All forms of amphetamines are banned by the International Olympic Committee and the NCAA.
