CDC Cannabis Strategy
The cultivation, legalization, and patterns of individual use of cannabis* in the United States is continually evolving. Additional states continue to enact medical and non-medical adult cannabis use legislation. Further, the potency of tetrahydrocannabinol (THC) in cannabis continues to increase and new strains of cannabis with varying levels of THC and cannabidiol (CBD) are being introduced into the marketplace. The number of persons who use cannabis is also increasing, including those reporting frequent cannabis use in the United States. Recognizing the need to understand changes in cannabis use patterns, the potential health and social consequences of cannabis use, and public health strategies to monitor and respond have led to the development of a Centers for Disease Control and Prevention (CDC) Cannabis Strategic Plan.
