Methamphetamine

Methamphetamine is a central nervous system stimulant drug that is similar in structure to amphetamine. Due to its high potential for abuse, methamphetamine is classified as a Schedule II drug and is available only through a prescription that cannot be refilled. Although methamphetamine can be prescribed by a doctor, its medical uses are limited, and the doses that are prescribed are much lower than those typically abused.

Aunque los médicos pueden recetar la metanfetamina, sus usos médicos son limitados y las dosis que se recetan son mucho más bajas que las que normalmente se consumen cuando se abusa.
