“The antiestrogenic effects of marijuana smoke condensate (MSC) and three major cannabinoids, ie., delta9-tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabinol (CBN), were evaluated…
The results showed that MSC induced the antiestrogenic effect via the ER-mediated pathway, while THC, CBD, and CBN did not have any antiestrogenic activity.
This suggests that the combined effects of the marijuana smoke components are responsible for the antiestrogenicity of marijuana use.”
