Evaluating the impact of cannabinoid extracts on chronic pain and quality of life in endometriosis patients – a pilot study

Posted on by

Women with endometriosis and chronic pelvic pain experienced significant improvements after adding a balanced oral THC cannabis extract to their existing treatment. In this prospective pilot study, 27 women completed three months of treatment, with benefits appearing within the first month and continuing through the study period.

Pain intensity fell significantly, along with the number of pain days and the need for conventional pain medicines. Use of both NSAIDs and opioid analgesics decreased, while fatigue, anxiety, central sensitization and pain-related disability also improved.

Quality of life improved across every measured EHP-30 domain, including pain, emotional well-being, work impairment, self-image and sexual relationships. The authors concluded that balanced THC cannabinoid medicines appear to be a potentially effective adjunct treatment for chronic pelvic pain and related symptoms in women with endometriosis.

“Endometriosis is a chronic gynecological disorder characterized by persistent pain and impaired quality of life, with limited effective treatment options. Emerging evidence indicates that cannabinoids may provide analgesic and symptom-relieving effects in chronic pain conditions.

This prospective single-center cohort study investigated the effects of standardized oral cannabis extracts (cannabinoid-based medicinal products, CBMPs) on pain and quality of life in women with endometriosis.

Thirty premenopausal women aged 18-45 years with confirmed endometriosis and chronic pelvic pain were enrolled; 27 completed the 3-month treatment period. Participants received oral CBMPs containing a balanced THC: CBD ratio. Pain intensity, frequency of pain episodes, analgesic use, fatigue, anxiety, central sensitization, disability, and quality of life were assessed using validated questionnaires (VAS, EHP-30, PDI, CFS, GAD-7, CSI).

Significant improvements were observed after one month of treatment, with continued benefit over three months. Pain intensity decreased markedly (p = 0.0004), accompanied by reductions in the number of pain days and analgesic use, including both NSAIDs (e.g., ibuprofen, diclofenac) and opioid analgesics (e.g., tramadol, tilidin, oxycodone) (p < 0.001). Fatigue (p = 0.0013), anxiety (p < 0.0001), central sensitization (p < 0.0001), disability (p < 0.0001), and overall quality of life (EHP-30) improved significantly.

Treatment was well tolerated; side effects were predominantly mild (severity score 1 on a 0-3 scale) and transient, occurring mainly during the titration phase and declining thereafter. Although limited by its single-center design, lack of placebo control, and short follow-up, this study provides preliminary evidence that oral CBMPs may represent a safe and effective adjunct therapy for managing pain and related symptoms in women with endometriosis. Larger randomized controlled trials are warranted to confirm these findings and establish optimal dosing strategies.”

“In conclusion, oral CBMPs with balanced THC: CBD ratios seem to be a safe and potentially effective adjunct therapy for chronic pelvic pain and related symptoms in women with endometriosis. By targeting both nociceptive and neuropsychological aspects of the condition, CBMPs can supplement existing pharmacological and lifestyle strategies, providing a more comprehensive approach to symptom management. These findings establish a basis for future controlled studies to refine dosing, investigate mechanisms, and assess long-term outcomes in this complex patient group.”

The Endocannabinoid System in Endometriosis-Associated Pain: Mechanisms, Molecular Targets, and Therapeutic Implications

Posted on by

A new 2026 review published in Reproductive Sciences examines the endocannabinoid system (ECS) as a therapeutic target for endometriosis-associated pain, a condition that can cause severe pelvic pain, painful menstruation, painful intercourse, and other chronic symptoms. The authors highlight the ECS because of its established roles in regulating pain, inflammation, and immune activity.

The review found that cannabinoids may influence three major mechanisms involved in endometriosis-associated pain: inflammation, pain signaling and sensitization, and the growth of endometriotic lesions. Cannabinoids interact with both cannabinoid and non-cannabinoid receptors found in endometriotic tissue, while also reducing inflammatory signaling from immune cells such as mast cells and macrophages.

The researchers conclude that the endocannabinoid system is a promising therapeutic target for endometriosis-associated pain, with cannabinoid therapies showing potential to regulate nociception, inflammation, and lesion proliferation. They call for clinical trials to further evaluate cannabinoid-based treatments for people living with endometriosis.

“Endometriosis is a chronic gynecological disorder affecting approximately 10% of reproductive-age women, characterized by the ectopic growth of endometrial tissue and severe pain, including dysmenorrhea, chronic pelvic pain, dyspareunia, dysuria, and dyschezia. Current treatments are limited in efficacy and associated with significant side effects, underscoring the urgent need for novel therapeutic strategies.

The endocannabinoid system (ECS) has emerged as a promising therapeutic target, given its well-established roles in pain modulation, inflammation, and immune regulation. Epidemiological evidence demonstrates that women with endometriosis increasingly use cannabis for symptom self-management, yet the underlying mechanisms remain poorly characterized.

This review integrates preclinical and human evidence to comprehensively evaluate the mechanistic basis of cannabinoid efficacy in endometriosis-associated pain. Evidence from in vitro studies and animal models indicates that cannabinoids target three main mechanisms of endometriosis-associated pain, including inflammation, nociceptive signaling, and lesion proliferation.

Cannabinoids suppress pain signaling and sensitization by interacting with cannabinoid and non-cannabinoid receptors expressed in endometriotic lesions. Cannabinoids attenuate endometriosis-induced inflammation by inhibiting proinflammatory cytokine signaling and reducing the release of inflammatory mediators by mast cells and peritoneal macrophages. Cannabinoids also exert antiproliferative effects in endometriosis models, thereby suppressing the growth of endometriotic lesions.

In conclusion, the ECS is a promising therapeutic target for endometriosis-associated pain, as it regulates nociception, inflammation, and proliferation. These promising findings highlight the potential therapeutic benefits of cannabinoids for endometriosis-associated pain, warranting the need for clinical trials to evaluate the safety and effectiveness of cannabinoid therapies in endometriosis.”
