Effort to Ease Cannabis Rules Faces New Opposition From Experts

A Harvard addiction scientist and a former government lawyer are urging the US Department of Justice to reject a plan that would ease federal restrictions on cannabis, which the industry has been counting on to grow their businesses.

In a new paper published Wednesday in JAMA Psychiatry, the authors argue that the Biden administration’s push to reclassify cannabis relied on flawed reasoning and downplayed health risks, including cannabis-use disorder and links to psychosis.
