Methamphetamine is a stimulant drug mostly used as a pill or powder.

Methamphetamine acts asa stimulant to the central nervous system; with the smokable form being a drug of abusealways referred to as meth, crystal meth or crank. It can be taken through snorting, smokingor injecting it into the body.
Explanation:
Methamphetamine is a stimulant that rapidly increases dopamine, the brain chemical that stimulates feelings of pleasure and motivation. Dopamine also affects thinking-related skills, like problem solving and memory.
In the short term, meth causes an intense high. But the crash that follows can leave you feeling irritable and depressed. Over time, meth use can kill your brain’s dopamine cells. You feel unable to find pleasure or have symptoms of psychosis and paranoia.
A commitment to treatment can help rebuild parts of the brain that take in dopamine. Those who quit meth show signs of impaired thinking-related skills at first. But with at least a year of staying drug-free, some harmful changes to your brain might reverse, the National Institute on Drug Abuse says.
