Methamphetamine is a synthetic (man-made) stimulant that is highly addictive. The drug is abused because it produces euphoric effects-sometimes described as a sense of well-being-that can last up to 24 hours. Methamphetamine is inexpensive and relatively easy to produce-making it affordable and readily available to teenagers. Crystal Methamphetamine resembles small fragments of glass or shiny blue-white "rocks" of various sizes. It has a higher purity level and may produce even longer lasting and more intense physiological effects than the powder form of the drug.
