†Stimulants are drugs that stimulate Central Nervous System (CNS) activity. There is no publicly available data which provides details of mental health disorders due to methamphetamine alone. Instead, data is presented for mental health disorders related to stimulant use (including amphetamines, Dexedrine, and speed).

Abuse: A maladaptive pattern of substance use leading to clinically significant impairment or distress.

Dependence: A maladaptive pattern of use in which the use of drugs or alcohol takes on a much higher priority for a person than other behaviours that once had greater value. The central characteristic is the strong, sometimes overpowering, desire to take the substance despite significant substance-related problems.
