Methamphetamine was first created in 1919 in Japan and was used by soldiers during WWII to stay awake. It later spread worldwide and its use became illegal in the US in 1970. Meth can be taken by injection, inhalation, smoking, or orally and goes by various street names. It is a Schedule II drug that carries risks of abuse and addiction. Meth contains toxic chemicals like antifreeze, ammonia, and battery acid. Its short and long term effects include increased heart rate and weight loss, as well as memory loss, paranoia, and damage to blood vessels over time. While it has limited medical uses, meth can destroy lives and relationships and negatively impact society.
