Why is methamphetamine addictive?
All addictive drugs have two things in common: they produce an initial pleasurable effect, followed by a rebound unpleasant effect. Methamphetamine, through its stimulant effects, produces a positive feeling, but later leaves a person feeling depressed. This is because it suppresses the normal production of dopamine, creating a chemical imbalance. The user physically demands more of the drug to return to normal. This pleasure/tension cycle leads to loss of control over the drug and addiction.
