CBD affects men and women differently, and that could have an impact on how the U.S. regulates the buzzy new substance.

Women may be more likely to use it to alleviate pain, sleep difficulties, anxiety and other health issues, according to Amy Abernethy, a top official with the Food and Drug Administration. CBD, the non-psychoactive compound in cannabis, was the focus of a scientific conference Thursday.

“We recognize there are significant knowledge gaps” around CBD, said Abernethy, the agency’s principal deputy commissioner of food and drugs. Areas that the FDA may explore include dosage levels, pregnancy and lactation, and whether pregnant women are more likely to develop a dependence on CBD, she and other speakers said.

The FDA Office of Women’s Health is coordinating with other parts of the agency to study CBD as its use spreads across products such as pet care, food, cosmetics and tinctures.

In one study, women also reported better results than men when using CBD to treat anxiety. [Read More @ Bloomberg]
