Does weed affect your period cycle?

The short answer is yes, marijuana can affect your period cycle. However, the degree of impact varies from person to person.

Research has shown that THC—the primary active compound in weed—can affect the estrogen and progesterone levels in the body which can lead to changes in menstrual cycles. For some people, this might mean having a lighter or no period at all, while for others it could be heavier bleeding or cramps and other symptoms associated with pre-menstrual syndrome (PMS). Additionally, using marijuana regularly may delay ovulation and thus lengthen menstrual cycles.

It should also be noted that changes in cycle are not permanent; when you stop smoking marijuana your body will eventually return to its normal hormonal balance and your period cycle should resume as normal.

However, if you experience irregularities with your cycle it is important to see a healthcare provider so they can determine if there are any underlying issues related to the effects of smoking weed on hormones, such as cysts or endometriosis.
