Methamphetamine
MDMA
Methamphetamine is an addictive stimulant drug that strongly activates
certain systems in the brain. Methamphetamine is chemically related to
amphetamine, but the central nervous system effects of methamphetamine are
greater. Both drugs have some limited therapeutic uses, primarily in the
treatment of obesity.
Methamphetamine is made in illegal laboratories and has a high potential for
abuse and addiction. Street methamphetamine is referred to by many names, such
as "speed," "meth," and "chalk." Methamphetamine hydrochloride, clear chunky
crystals resembling ice, which can be inhaled by smoking, is referred to as
"ice," "crystal," "glass," and "tina."
