MethamphetamineMethamphetamine
Methamphetamine is a powerful Methamphetamine is a powerful central nervous system stimulant that central nervous system stimulant that strongly activates multiple systems in strongly activates multiple systems in the brain. Methamphetamine is closely the brain. Methamphetamine is closely related chemically to amphetamine, related chemically to amphetamine, but the central nervous system effects but the central nervous system effects of methamphetamine are greaterof methamphetamine are greater..
