Methamphetamine (meth) is a synthetic stimulant that is highly addictive and affects the central nervous system. Crystal meth is a form of the drug that looks like glass fragments or shiny, bluish-white rocks. Meth use can cause significant health problems, and long-term use can even result in severe health complications and death.

Methamphetamine was developed by scientists in the early 20th century to improve the [ADHD](/content/blog/adhd-quiz "Do I Have ADHD? Take the Assessment"/index.html) drug amphetamine. However, it turned out stronger than expected and is now labeled as a Schedule II drug, meaning it has a high potential for addiction, but it is legal in certain contexts.

Why is Meth So Addictive?

Meth speeds up activity in the central nervous system, causing users to feel euphoric, powerful, and alert. This euphoric feeling results from the release of dopamine, which floods the parts of the brain that regulate pleasure. The effects can last from 6-18 hours, making the “high” much longer than other stimulants like cocaine, thus increasing its addictive potential. The method of use also affects the intensity and length of the high.
