METHAMPHETAMINE ADDICTION IN THE BRAIN AND BODY
When you use meth — whether smoking, ingesting or injecting — the drug almost immediately takes control of your brain’s pleasure and reward systems. Using meth mimics the sensations of happiness that you feel when you accomplish something, and it does so to an extreme degree. Many meth users will binge on the drug to make this euphoric period of the high last as long as possible; sometimes up to several days. But this overstimulation means that the crash after the high is often equally intense. Users may experience extreme paranoia, itchy hallucinatory sensations and exhaustion. With long-term abuse, these symptoms will become more intense and you will require increasingly larger doses of meth to keep them at bay.
Your body also suffers from meth abuse. During a meth high, you may experience a rapid heart rate, increased libido, dry mouth and decreased appetite. With continued meth use, these effects can take their toll, leading to weakened blood vessels and high blood pressure, sexual deficiencies, tooth decay and extreme weight loss. Additionally, many meth abusers suffer from skin sores as a result of scratching themselves during withdrawal periods. Finally, the risky sexual behaviors often associated with the meth-using community leads to a statistically higher risk of contracting sexually transmitted infections and viruses.
