How Marijuana Can Affect The Menstrual Cycle

Table of Contents

For many girls and women, menstruation is an uncomfortable monthly event. The physical discomfort and emotional toll make it a challenging experience. Interestingly, some people claim that marijuana helps relieve cramps and other period-related pain. But, recent studies suggest that marijuana may also bring about unintended effects on the menstrual cycle. While research on marijuanaā€™s interaction with reproductive health is still evolving, itā€™s essential to weigh the potential impacts. Hereā€™s a closer look at how marijuana can affect the menstrual cycle.


The Menstrual Flow

Typically, a woman loses between 10 and 35 milliliters of blood during each period, but this can vary greatly based on factors like stress, diet, and use of hormonal birth control. A heavy flow is often linked to higher estrogen levels and low progesterone, as hormone levels fluctuate during the menstrual cycle.

Leading up to a period, progesterone levels spike as the uterus prepares for a potential pregnancy. If no fertilization occurs, progesterone levels drop, triggering a “progesterone withdrawal” that causes the endometrial lining of the uterus to shed, resulting in bleeding.

Marijuanaā€™s Impact on Menstruation

Emerging research shows that cannabis use may influence menstrual flow and hormone levels. For example, a 1985 study noted that THC, the psychoactive compound in marijuana, may reduce progesterone levels in uterine cells. Lower progesterone levels can impact menstrual flow, sometimes leading to heavier bleeding. Another possible effect is that marijuana may lower luteinizing hormone (LH) levels, a hormone critical in preparing the body for ovulation. A reduction in LH can disrupt the thickening of the endometrial lining, potentially leading to lighter or irregular periods.

In an additional twist, marijuana contains apigenin, a compound that mimics estrogen. This interaction could contribute to the connection between the endocannabinoid system and estrogen-related processes, influencing menstrual patterns.


Managing Marijuana Use and Reproductive Health

While the potential benefits of marijuana for period pain are reported anecdotally, its broader effects on reproductive health remain under-researched. Given marijuanaā€™s potential influence on menstrual hormones, it’s advisable for women to use it with caution, especially those seeking to regulate or manage their menstrual health.
