Can Using Medical Marijuana Increase Anxiety and Depression?

As of this writing, 30 states, Guam, the District of Columbia, and Puerto Rico all have approved the broad use of medical marijuana. Additionally, other states allow limited medical use and 8 states (and the District of Columbia) allow recreational use of the drug. Even though the use of pot and weed is becoming more acceptable, the Drug Enforcement Administration (DEA) still considers marijuana to be a Schedule I substance, meaning it is likely to be abused and it completely lacks medical value. This classification also means there hasn’t been much research into the efficacy of the drug for medical conditions and, in particular, we lack long-term studies that would tell us whether it is safe and/or effective when used over a long period of time.
