Dr. Strouse will review the current status of cannabis legalization around the country and address the current science regarding the risks to individuals known to be associated with cannabis use/abuse, with an emphasis of impacts on the developing brain, intellectual and school functioning, and psychosis risk. Participants will also learn about the scientific evidence on therapeutic effects of cannabinoids and what the public health data shows in terms of motor vehicle safety, non-behavioral health effects, the impacts of cannabis legalization on opioid overdose deaths, and impacts on prescription patterns in states with cannabis legalization.
