The cannabis industry has flowered into a billion-dollar industry in the last decade. Now, cannabis is easier than ever to legally access for medical or recreational use in the majority of U.S. states. But does legalization mean that cannabis is actually safe to use? After all, cannabis is still federally classified as a Schedule 1 controlled substance, defined by the Drug Enforcement Administration as a substance with “no currently accepted medical use and a high potential for abuse.” (Though the Senate’s Cannabis Administration and Opportunity Act proposes to end cannabis’s federal prohibition.) But even under current restrictions, some researchers have interrogated assumptions about the addictive potential of cannabinoids, the chemical compounds of the cannabis plant, and investigated their therapeutic properties. With the help of leading cannabis researchers, host Dr. Alok Patel explores current studies to find out what science can tell us about the therapeutic potential, risks, and long-term effects of cannabis on your body and brain.
