Health Effects
Since methamphetamine is a Schedule II stimulant, it has a high potential for abuse and it is highly addictive. It affects the brain and the central nervous system and releases large amounts of dopamine in the brain creating a euphoric rush. A symptom of addiction is becoming physically dependent on the drug. Following the "rush", feelings of depression and irritation follow. Symptoms of withdrawal are: depression, loss of energy, shaking, nausea, hyperventilation, increased appetite, and sweating. A methamphetamine overdose occurs so suddenly that the user who overdosed most likely would not even be aware of it. An overdose usually leads to a heart attack or a stroke. A person who has overdosed will have a high temperature, cardiovascular collapse, increased heart rate, dilated pupils, and kidney failure. Symptoms of overdosing begin nearly instantaneously.
