Preclinical study links human gene variant to THC reward in adolescent females

A common variation in a human gene that affects the brain's reward processing circuit increases vulnerability to the rewarding effects of the main psychoactive ingredient of cannabis in adolescent females, but not males, according to preclinical research by Weill Cornell Medicine investigators. As adolescence represents a highly sensitive period of brain development with the highest risk for initiating cannabis use, these findings in mice have important implications for understanding the influence of genetics on cannabis dependence in humans.

MAiD is not driven by socioeconomic vulnerability or poor access to palliative care

A new study of people who received medical assistance in dying (MAiD) in Ontario found that about three-quarters were cared for by palliative care practitioners at the time of their request for MAiD, and MAiD recipients were younger, wealthier and more likely to be married than the general population at time of death. These findings dispel concerns that MAiD requests are driven by lack of access to palliative care services or by socioeconomic vulnerabilities.The article is published in CMAJ (Canadian Medical Association Journal) along with a related editorial.
