What are the Physical Effects of Meth?

You may be wondering, “what are the effects of methamphetamine?”.
Meth use brings about brief waves of pleasure and euphoria.

However, these effects of meth on the body are short-lived, and users begin to experience strong cravings to recreate these feelings.
This pattern of use can quickly turn into dependence followed by addiction.

Meth is the abbreviated name for crystal methamphetamine.
There are many street names for meth, including crystal meth, ice, and crank.

These highly addictive drugs are classified as psychostimulants that can be smoked, snorted, or injected.
Prolonged meth abuse leads to serious mental and physical health problems.

Meth not only damages the brain but also causes both external and internal damage to the body.
Some physical effects of methamphetamine may be irreversible.

Meth Addiction Treatment At Renaissance Recovery

While medication-assisted treatment is effective for treating many substance use disorders, there are currently no FDA-approved drugs that prolong abstinence from meth or inhibit further meth usage.

Instead, behavioral therapies are the most effective treatments for meth addiction, specifically cognitive behavioral therapy (CBT) and contingency management (CM).

The Matrix Model can also be applied to stimulant use disorders like meth addiction. This involves comprehensive treatment over a four-month period, including:

  • Individual counseling
  • Behavioral therapy
  • Family counseling
  • 12-step programs
  • Drug testing
  • Incentivized health behaviors
