Is nicotine an aromatase inhibitor?

Nicotine, its major metabolite cotinine, and other tobacco alkaloids were indeed found to inhibit aromatase activity in human trophoblasts, granulosa cells, and breast cancer cells, presumably through direct competitive binding to the active site of the enzyme (7,8).

Is nicotine an estrogen blocker?

Nicotine and its metabolite continine are strong inhibitors of the aromatase. With regard to investigations in smoking women, suggesting a decreased endogenous estrogen production, our results indicate that smoking might influence growth and treatment results of hormone-dependent human cancer.

In addition to these effects, nicotine reduces circulating estrogen (the female sex hormone) levels and leads to early onset of menopause in women.
