Meth is a highly addictive drug with potent central nervous system stimulant properties. Those who smoke or inject it report a brief, intense sensation or rush. Oral ingestion or snorting produces a long-lasting high instead of a rush, which reportedly can continue for as long as a day. (United States, U.S. Department of Justice, Drug Enforcement Administration. Drugs of Abuse 2015 Edition: A DEA Resource Guide.)
Chronic meth abusers can exhibit:
- violent behavior
- anxiety
- confusion
- insomnia
- paranoia that can result in homocidal or suicidal thoughts
- aggression
- visual and auditory hallucinations
- mood disturbances
- delusions such as the sensation of insects creeping on or under the skin
Taking even small amounts of meth can result in:
- increased wakefulness
- increased physical activity
- decreased appetite
- rapid breathing and heart rate
- irregular heartbeat
- increased blood pressure
- hyperthermia (overheating)
High doses can elevate body temperature to dangerous, sometimes lethal, levels and cause convulsions and even cardiovascular collapse and death. Meth abuse may also cause extreme anorexia, memory loss and severe dental problems. (United States, U.S. Department of Justice, Drug Enforcement Administration.
