How CBD is helping women with endometriosis
4th August 2020
Women around the world are increasingly using CBD to deal with the symptoms of endometriosis – a much misunderstood and misdiagnosed condition. Cannabis Health finds out more.
Endometriosis is the second most common gynecological condition in the UK, affecting around one in 10 UK women – although frequent misdiagnosis and a lack of understanding means this figure may be higher.
It happens when tissue similar to the lining of the womb starts to grow in other places, such as the ovaries and fallopian tubes, which then reacts to the menstrual cycle each month and also bleeds.
However, there is no way for this blood to leave the body, causing inflammation, pain and the formation of scar tissue.
Nobody knows what causes it, or why some women suffer and others don’t, and symptoms, including pain in the lower abdomen and back, nausea, intense fatigue and infertility, can be debilitating.
According to Endometriosis UK, it takes an average of seven and a half years from onset of symptoms to get a diagnosis, and the condition costs the UK economy £8.2bn a year in treatment, loss of work and healthcare costs.
There is currently no cure, and treatment is limited to painkillers, hormonal contraception, or surgery to cut away the scar tissue. In more severe cases, the only option may be a full hysterectomy to remove part or all of the affected organs.
But could there be another way? More and more women are turning to CBD to ease their symptoms, and the results are encouraging.
Charlotte Nichols, managing director of North East of England-based PR firm Harvey & Hugo, has been using a CBD oil for a couple of months, and has already noticed a difference in her symptoms.
She explained: “I was diagnosed with endometriosis in 2017 but I’d been suffering with it for three years before that; it took that long to diagnose as it was just put down to ‘just’ painful periods.
“I had surgery to remove it but still struggled with infertility, until I finally got pregnant in 2018. The symptoms disappeared while I pregnant and breastfeeding but then came back with a bang since – I’d forgotten how awful it was.”
After researching how CBD could help, Charlotte began taking the oil in June 2020, and the results have been significant.
She said: “While the CBD doesn’t stop the pain completely, it definitely helps take the edge of the symptoms.
“Stress and lack of sleep both make my symptoms worse, and the oil has definitely helped with this, helping me relax and dramatically improving my sleep.
“I’ve also found that the CBD has improved my mood, as feeling so rubbish all the time was getting me down. That might be the effect of the oil itself, or simply because it’s alleviating the symptoms – either way, it’s making me feel more like myself again.”
While using CBD as a painkiller is nothing new, experts believe that its use for endometriosis may be down to more than simple pain relief.
Research has found that cannabinoids also help by:
- Stopping the endometrial cells from multiplying
- Preventing them from migrating to other parts of the reproductive system
- Stopping the blood supply to the lesions – effectively starving them of the nutrients they need to grow
- Regulating nerve growth
- Reducing inflammation
- Modulating the immune response
- Desensitising the nerves that transmit pain.
In fact, some scientists believe that dysfunction in a woman’s endocannabinoid system – the molecular system responsible for regulating and balancing processes in the body, including immune response – may be behind endometriosis.
Dr Michele Ross, CEO of Infused Health, explains: “Reduced function of the endocannabinoid system leads to the growth of endometriosis throughout the body, and more pain.”
CB1 cannabinoid receptors mediate the pain from endometriosis and, according to a 2010 study, are present in the cells that supply nerve impulses to the endometrial growth.
However, the endometrial cells of women with endometriosis have been found to have a lower expression of CB1 receptors — so activating the few that are expressed is even more important for those in pain.
Whatever the science behind it, women like Charlotte are just pleased to finally have a natural product to alleviate their symptoms.
“I much prefer taking CBD to other painkillers, as I’m very aware of what I’m putting into my body and, as far as I’m concerned, the more natural the better,” she says.
“At the moment I’m just using the oil; I haven’t tried any other products, like the balms or lotions, but I’m going to look into it.
“I also find that exercise, intermittent fasting, avoiding alcohol and cutting down on sugar really helps my symptoms, in combination with the CBD. It’s been a long road, with a lot of trial and error along the way, but I’m so glad to finally feel in control of my body again.”

Cannabis reduces OCD symptoms by half in the short-term
17th November 2020
People with obsessive-compulsive disorder, or OCD, report that the severity of their symptoms was reduced by about half within four hours of smoking cannabis, according to a Washington State University study.
The researchers analysed data inputted into the Strainprint app by people who self-identified as having OCD, a condition characterised by intrusive, persistent thoughts and repetitive behaviours such as compulsively checking if a door is locked. After smoking cannabis, users with OCD reported it reduced their compulsions by 60%, intrusions, or unwanted thoughts, by 49% and anxiety by 52%.
The study, recently published in the Journal of Affective Disorders, also found that higher doses and cannabis with higher concentrations of CBD, or cannabidiol, were associated with larger reductions in compulsions.
“The results overall indicate that cannabis may have some beneficial short-term but not really long-term effects on obsessive-compulsive disorder,” said Carrie Cuttler, the study’s corresponding author and WSU assistant professor of psychology. “To me, the CBD findings are really promising because it is not intoxicating. This is an area of research that would really benefit from clinical trials looking at changes in compulsions, intrusions and anxiety with pure CBD.”
The WSU study drew from data of more than 1,800 cannabis sessions that 87 individuals logged into the Strainprint app over 31 months. The long time period allowed the researchers to assess whether users developed tolerance to cannabis, but those effects were mixed. As people continued to use cannabis, the associated reductions in intrusions became slightly smaller suggesting they were building tolerance, but the relationship between cannabis and reductions in compulsions and anxiety remained fairly constant.
Traditional treatments for obsessive-compulsive disorder include exposure and response prevention therapy where people’s irrational thoughts around their behaviours are directly challenged, and prescribing antidepressants called serotonin reuptake inhibitors to reduce symptoms. While these treatments have positive effects for many patients, they do not cure the disorder nor do they work well for every person with OCD.
“We’re trying to build knowledge about the relationship of cannabis use and OCD because it’s an area that is really understudied,” said Dakota Mauzay, a doctoral student in Cuttler’s lab and first author on the paper.
Aside from their own research, the researchers found only one other human study on the topic: a small clinical trial with 12 participants that revealed that there were reductions in OCD symptoms after cannabis use, but these were not much larger than the reductions associated with the placebo.
The WSU researchers noted that one of the limitations of their study was the inability to use a placebo control and an “expectancy effect” may play a role in the results, meaning when people expect to feel better from something they generally do. The data was also from a self-selected sample of cannabis users, and there was variability in the results which means that not everyone experienced the same reductions in symptoms after using cannabis.
However, Cuttler said this analysis of user-provided information via the Strainprint app was especially valuable because it provides a large data set and the participants were using market cannabis in their home environment, as opposed to federally grown cannabis in a lab which may affect their responses. Strainprint’s app is intended to help users determine which types of cannabis work the best for them, but the company provided the WSU researchers free access to users’ anonymised data for research purposes.
Cuttler said this study points out that further research, particularly clinical trials on the cannabis constituent CBD, may reveal a therapeutic potential for people with OCD.
This is the fourth study Cuttler and her colleagues have conducted examining the effects of cannabis on various mental health conditions using the data provided by the app created by the Canadian company Strainprint. Others include studies on how cannabis impacts PTSD symptoms, reduces headache pain, and affects emotional well-being.
