Marijuana is a Schedule I drug according to the DEA, meaning it has a high potential for abuse and no accepted medical use. It contains THC, which passes to the brain and causes psychological and physical effects like increased anxiety and depression, impaired memory and coordination. While some claim it helps with medical conditions, there is no solid evidence it improves health; side effects include increased heart rate and risk of accidents. Possession can result in misdemeanor charges with up to 1 year in jail or felony charges with 1-10 years in prison. Withdrawal symptoms are mild compared to harder drugs and include insomnia, anxiety, and headaches.
