Methamphetamine

Overview

Methamphetamine is a type of Amphetamine-Derivative - is almost exclusively used illegally as a recreational substance.  It is regarded as the most potent ( most "addictive" and most widely abused ) of the various Amphetamine-Derivatives.  Methamphetamine is more potent than the second most potent Amphetamine-Derivative (Dextroamphetamine) Methamphetamine appears to differ from Amphetamine in that it causes greater release of Dopamine within the Brain.

An overdose can occur at a dosage of as low as 50 mg of pure Methamphetamine.
