Today, the Cannabidiol Research Expansion Act (S. 3269) was introduced in the United States Senate, which would ease research barriers and create exemptions from federal law for certain medical cannabis patients. The bill was introduced by four members of the Senate Judiciary Committee - Dianne Feinstein (D-CA), Chuck Grassley (R-IA), Patrick Leahy (D-VT), and Tom Tillis (R-NC). Much of the bill is focused on allowing for institutions of higher education or manufacturers to register with the federal government in order to conduct research on cannabis (marijuana) or cannabidiol (CBD), but it’s the “Safe Harbor” provision that is drawing the attention of medical cannabis patients.
