The Prevalence of Cannabis Use Disorder in a Legalized State

A study conducted in Washington state, one of the first states to fully legalize cannabis, found that cannabis use disorder (CUD) is common among both medical and recreational marijuana users. The study revealed that using both medical and recreational marijuana led to a more severe addiction than using medical marijuana alone. Frequent use of marijuana was identified as a significant risk factor for developing CUD. The prevalence of CUD was found to be higher among non-medical users, with potential consequences including mental disorders, cognitive deficits, and violent behavior. Similar findings have been observed in other countries where marijuana is legal. The study highlights the need for better understanding, education, and treatment of CUD as cannabis use becomes increasingly legal and available.
