Drug Addiction


  • Drug addiction is a disease that affects your brain and thus your behavior.

  • It also leads to an inability to control your use of medication or drugs.

  • You can become addicted to illegal drugs like heroin and meth, or legal drugs like alcohol, anti-anxiety medications, or even painkillers.

Over time, you might need higher and higher doses of drugs to get the same high.

  • Once you become addicted to the drug, you might have difficulty avoiding it.

  • Attempts to stop using drugs may result in intense cravings, or withdrawal symptoms.
