Methamphetamine – Effects, Risks & Detectability

Methamphetamine is a synthetic stimulant belonging to the amphetamine group. It has a strong activating effect on the central nervous system and is commonly known under names such as Crystal, Crystal Meth, Meth, Ice. Due to its rapid and intense effects, the risk of abuse and dependence is significantly increased.
