How addictive is meth?
Comparing meth to other drugs of abuse
By Nicole Stricker nstricker@postregister.com
Just how addictive is methamphetamine? Thats hard to measure since different addictive drugs act on different parts of the brain and are abused for different reasons.
Cocaine is classically considered the most addictive recreational drug, according to Nora Volkow, director of the National Institute on Drug Abuse. It increases the brains level of dopamine a molecule that triggers good feelings and stimulates the brains natural reward system.
Meth releases five times as much dopamine as cocaine.
It is more addictive than crack, a smokable form of cocaine that delivers the drug more efficiently. Heroin and nicotine are considered harder to kick because both come with physical withdrawal symptoms. But meth and cocaine cause addiction more quickly sometimes after just one use and can trigger more powerful cravings.
Here are some other comparisons between cocaine and meth.
