Can Cannabis Interfere with Menstrual Cycle or Contraceptives?

Treating menstrual symptoms with cannabis has been a known possibility for hundreds of years in India and China, before the criminalization of the plant in these countries. Its analgesic and anti-inflammatory properties can provide patients with relief from the characteristic pains of this period, such as cramps, and help regulate the endocannabinoid system in case the patient has menstrual cycle disorders.

Acne, which can be a symptom of menstrual cycle disorders, can also be treated this way. A study suggests that dermocosmetics containing cannabis in their formulation are effective in treating acne due to the presence of endocannabinoid receptors in the sebaceous glands, which contribute to skin homeostasis.

Can cannabis consumption interfere with the menstrual cycle?

The answer is yes. In an interview with Sechat, gynecologist Dr. Mariana Prado explained that "when the plant is used without criteria, without symptoms to treat, it is suggested that it may interfere with hormonal, menstrual, and ovulatory issues (fertility disorders)."

For these reasons, it is important to report cannabis consumption to the gynecologist during consultation, if the patient does so, for a complete analysis. Even for choosing contraceptives, the subject should be addressed. As Dr. Mariana elucidates, "CBD can interact with the estrogen in the contraceptive, reducing its effectiveness, shortening the elimination time of cannabis from the body, and causing drowsiness. In terms of harm reduction, we prioritize non-hormonal contraceptives or those with only progesterone. Furthermore, I emphasize that there is a lack of concrete data in the literature to affirm whether there is an interaction with contraceptives and cannabis use."
