Cannabis and Cannabinoids (Marijuana): Affordability and access - CancerChoices

Medical cannabis and cannabinoids in raw or dried flowers, oils, capsules, powders, edibles, and topicals may reduce pain, and some evidence shows benefit with nausea, vomiting, and sleep, but little evidence of improving treatment outcomes.

Affordability and access

Although authorized medical cannabis use has become accepted and normalized in many places, cannabis and its cannabinoids are still listed as Schedule 1 controlled substances under federal law, officially considered “drugs with no currently accepted medical use and a high potential for abuse.”1United States Drug Enforcement Administration. Drug Scheduling. United States Department of Justice. Viewed October 9, 2021.

Because federal law regulating cannabis supersedes state law, people may still be subject to arrest and charged with possession even in states where medical cannabis is permitted.2Mayo Clinic. Consumer health: Medical marijuana. Mayo Foundation for Medical Education and Research. November 27, 2019. Viewed October 9, 2021. However, a federal amendment which protects medical cannabis patients and businesses from prosecution in states where it is legal has been included in every federal spending bill since 2014.3Rohrabacher-Farr Amendment. JD Supra, LLC. October 9, 2021. Viewed October 9, 2021.
