Learn more about menstrual pain

I have seen a recurring scene in movies and TV shows where a group of girls hides in a bathroom stall exchanging secret pills to alleviate menstrual cramps. There are many myths and stigmas against menstruation and the “addictive” use of menstrual pain relief. How much do you know about menstrual cramps? Are you aware of the ways to relieve menstrual cramps? Are menstrual pain relief actually addictive? Can marijuana be used as a remedy for menstrual cramps? I hope this post can advance your understanding of menstrual pain and pain relief.

Dysmenorrhoea is the medical name for menstruation pain. The primary symptoms of dysmenorrhoea can range from mild discomfort to severe cramping that could interfere with daily functioning. Other symptoms include diarrhea, nausea, vomiting, headache, and dizziness. Dysmenorrhoea is the result of natural menstrual cycles, in which increased prostaglandin release causes hyper-contractions of the uterus that eventually stimulate pain receptors. Although dysmenorrhoea is not classified as chronic pain based on the standard definitions, it is not “curable” as a natural process and is impacting at least 80% of women monthly for about 40 years of their life ( Grandi et al., 2012; NCCIH). To date, the most effective and common treatment of dysmenorrhoea is non-steroidal anti-inflammatory drugs (NSAIDs). These are often over-the-counter pain relievers such as ibuprofen and naproxen that suppress the production of prostaglandin, thus reducing the level of dysmenorrhoea from its root (Marjoribanks et al., 2015). Other treatment examples are hormonal contraceptives (e.g., birth control pills) and exercise (Seifalian et al., 2022). To break the myth – – – NSAIDs do not pose any risk of addiction, but there are potential side effects such as blood clotting, kidney issues, nausea, and vomiting due to long-term usage (Marjoribanks et al., 2015).

In recent years, the use of cannabis to relieve menstrual cramps has become a hot topic. Surveys in several countries found that a great proportion of women in their samples self-reported the illicit use of cannabis to treat dysmenorrhoea​​ or expressed the willingness to use cannabis as a self-management tool for dysmenorrhoea​​n (Armour et al., 2021; Han et al., 2021; Sinclair et al., 2020). However, there is very limited research on the use of cannabis for menstrual pain relief. A recent study investigated the effect of paeonol, the main component isolated from the root bark of Paeonia suffruticosa, in treating dysmenorrhoea using rats (Peng et al., 2020). The study found that paeonol alleviated dysmenorrhoea by activating the endocannabinoid CB2 receptors and inhibiting the intracellular calcium influx in uterine smooth muscle cells, thus reducing uterine contraction. Although paeonol is not a cannabis extract, its engagement with CB2 receptors suggests the potential of targeting cannabis and the endocannabinoid system in alleviating dysmenorrhoea. It is worth noticing that the study did not find that activating CB1 receptors by paeonol was effective in dysmenorrhoea relief. Existing literature tends to agree with the CB1 receptor being responsible for the psychoactive effect of cannabis, whereas the CB2 receptor is primarily responsible for anti-inflammatory and immunosuppressive actions (Ashton & Glass, 2007). The result of this study might be exciting for many women that want the analgesic effect but worry about the psychoactive effect of cannabis. In fact, many cannabis-related treatments for dysmenorrhoea available in the market advertise their CBD-only and zero-THC ingredients (e.g., tampon containing CBD oil) because THC is classically considered as the psychoactive ingredient of cannabis. However, these CBD treatments for dysmenorrhoea have not undergone clinical examination, and there is no existing research that directly investigates the analgesic effect of cannabinoid ingredients for dysmenorrhoea.

Among surveys and media discussions of using cannabis for menstrual pain relief, the most reported benefits of cannabis are its analgesic effect and the reduction in nausea and vomiting. Indeed, existing literature has shown the potential of cannabis and the endocannabinoid system in reducing general pain, nausea, and vomiting (Parker, 2018). However, more research on the relationship between cannabis and dysmenorrhoea is crucial because of the side effects, stigma, and legalization status of cannabis consumption.

  1. Hi! I really liked your article! As someone who actually struggles with menstrual pain, this read was quick and insightful to the usage of “drugs” to lessen dysmenorrhoea. I think there was a clear hook to this, and it definitely drew me in. Something that I would like to appreciate is how, although at times your explanations were filled with jargon that was hard to follow, you still unpacked much of the information in an understandable way.


  2. This was a super interesting read. I did not know that people used cannabis for menstrual pain. I am interested to know if the effects are at all different when menstruating vs not or if they have any interactions with the other symptoms of menstruation or PMS (such as emotional symptoms). I also wonder if cannabis can be prescribed for medical usage of relieving menstrual pain and how this fits into social stigmas.


  3. Hello! I found this article very intriguing as I have struggled with dysmenorrhoea throughout my life. I have never heard or even thought of cannabinoids’ ability to relive menstrual pain. Something I would like to learn more about are the mechanisms of analgesic effects of cannabinoids on the brain.


  4. This article is so interesting!!! I wish there was more research out there on its effects on period symptoms because it could be such a great solution. It would be interesting to see if there are forms that are more effective than others. Like is smoking weed just as beneficial as using a CBD infused tampon? I wish in general they would do more research on how to alleviate period symptoms as they can be so debilitating for many women. This article was so well written and very engaging! Most jargony terms were explained making this an easy yet informative read.
