Marijuana has gained recent interest due to its antitumor potential. However, some studies have shown that it can reduce VEGF. VEGF is important for the growth of follicles.
One study states “In vitro and in vivo experiments show that at least two mechanisms may be involved in this cannabinoid action: the direct inhibition of vascular endothelial cell migration and survival as well as the decrease of the expression of proangiogenic factors (vascular endothelial growth factor and angiopoietin-2)…”
