Methamphetamine addiction is a physical dependence on the stimulant drug. Using methamphetamine, more commonly referred to as meth, can lead to addiction, which in turn may cause serious harm including long-term health problems, mental illness, and potentially even death from an overdose. Meth addiction can be treated with residential treatment, ongoing behavioral therapies, and access to a strong support network, although there is no medication currently approved to treat this addiction.
