Marijuana drug facts and mythsFor an explanation of some of the terms used please see our Drug Test Glossary. Marijuana and mental illness:Myth: Marijuana can cause psychological damage and irrational behavior. Fact: Some users have been known to suffer anxieties from the use of marijuana, primarily paranoia. This is not a long term symptom of marijuana use though. Marijuana and addiction:Myth: Long time marijuana users develop a physical and mental addiction. Fact: Less than 1% of marijuana users smoke on a daily basis. Some long term users have no difficulties quitting, others require counseling. This is due to a mental addiction and not physical. Marijuana has increased in potency:Myth: Todays youths are being exposed to more potent forms of marijuana. Fact: It has been proven the science the DEA is using to back these claims are flawed. Even if potency were to increase this does not pose more of a risk. Marijuana users are lightly punished:Myth: Hardly any marijuana users are incarcerated.
