Laboratory research led by scientists at Khon Kaen University indicates that cannabidiol (CBD) and delta-9-tetrahydrocannabinol (THC), two key cannabis compounds, can slow the growth and spread of ovarian cancer cells in vitro, particularly when used together in a 1:1 ratio, while causing relatively limited damage to healthy cells. The early-stage findings, reported in Frontiers in Pharmacology, suggest a potential avenue for future ovarian cancer treatments but are far from clinical use.
Researchers from UC San Diego and 23andMe have discovered genetic links to cannabis use behaviors, connecting them to over 100 health traits. The study, published on October 13, 2025, in Molecular Psychiatry, highlights two key genes and could inform prevention of cannabis use disorder. It analyzed data from nearly 132,000 participants to explore early-stage risks.
