Medical Use of Cannabis in 2019 Kevin P. Hill, MD, MHS JAMA, Published online August 9, 2019 doi:10.1001/jama.2019.11868   Nearly 10% of cannabis users in the United States report using it for medicinal purposes.1 As of August 2019, 33 states and the District of Columbia have initiated policies allowing the use of cannabis or cannabinoids for the management of specific medical conditions.
