Abstract
Cannabis has been employed medicinally throughout history, with recent renewed interest for use due to media awareness and medical marijuana legislation. The geriatric population, identified as those 65 years of age and older, is increasingly using cannabis-derived products, has a higher likelihood of having multiple comorbidities, and is subject to polypharmacy. These individuals are at increased risk of psychiatric and other medical adverse events due to their decreased physical and cognitive reserve and changes in their physicality. Recreational use of cannabis in this population has not been well studied, but medical marijuana use has been investigated more frequently. Increased nonmedical use increases the risk of adverse health consequences. Heavy regular use can lead to cannabis use disorder (CUD), which is formerly known as cannabis abuse and dependence, and may also lead to impaired social functioning and psychiatric comorbidity. The pattern of patients admitted to hospitals has dramatically changed recently, with an increased number of elderly patients being frequently admitted. As such, due to the ease of accessing CBD, this vulnerable cohort is seen more frequently in the hospital, and we need to be more vigilant and inquire about cannabis use as we do, asking about routine medications and over-the-counter supplements. In the U.S., marijuana laws have been changing rapidly, and Americans increasingly favor legalizing cannabis for medical and recreational uses. Policymakers should ensure that training on cannabis screening and interventions for CUD are provided to clinicians to equip them better to monitor and treat patients with cannabis-related problems.
