Study Stopped
Recruitment has been challenging due to the BMI cutoff, need to take oral progesterone and abstain from cannabis products prior to the study.

Brief Summary
The investigators are looking to conduct a study looking at the effects of cannabidiol (CBD) in patients with endometriosis. It is believed that CBD will improve both pain and quality of life. The study will last a total of 12 weeks and involve several onsite visits in addition to daily pain assessments.

Outcome Measures
Primary Outcomes (1)
Pain Score Area Under the Curve (AUC)
Pain will be self-reported daily using the Visual Analog Scale, a 100mm horizontal line on which the patient's pain intensity is represented by a point between the extremities of 0 (no pain) and 100 (worst pain). Although the daily collection is based on the 0-100 point scale, the primary study endpoint is calculated as the area under the curve per patient using the trapezoidal rule, with an AUC range per patient of 0-5600 over 8 weeks.
8 weeks
Study Arms (3)
Group A - Placebo
PLACEBO COMPARATORNorethindrone acetate (5mg daily) + Placebo
Group B - Low Dose CBD
ACTIVE COMPARATORNorethindrone acetate (5mg daily) + Low dose CBD (10mg sublingual daily)
Group C - High Dose CBD
ACTIVE COMPARATORNorethindrone acetate (5mg daily) + High dose CBD (20mg sublingual daily)
Interventions
Cannabis is a well-known plant that contains more than 500 identified phytochemicals of which over 100 are cannabinoids. The most widely studied is 9-tetrahydrocannabinol (9-THC), which is the major psychoactive component of Cannabis, but Cannabidiol (CBD) has been increasingly favored for its reduced side effect profile and potential health benefits. CBD was first isolated from Cannabis in the 1940s. CBD, unlike 9-THC, does not bind to CB1 and CB2 receptors, which accounts for its lack of typical psychotropic effects, but is still appears to work via alternative mechanisms via the endocannabinoid system.
Norethindrone is a form of progesterone, a female hormone important for regulating ovulation and menstruation.

Eligibility Criteria
You may qualify if:

- Agrees to use approved contraception during the entire study if not surgically sterile
- Patients using oral contraceptives, vaginal ring, injectable progesterone and/or GnRH agonists/antagonist for contraception and/or management of endometriosis, can be included if both they and their primary provider agree to stopping their medication and transitioning to Norethindrone acetate (NETA) as the primary treatment of endometriosis throughout the study period.
- Patients using Long-acting reversible contraceptives (LARCs) for contraception and/or management of endometriosis can be included if both they and their primary provider agree to initiate Norethindrone (NETA) as the primary treatment of endometriosis throughout the study period
You may not qualify if:
- Women that are pregnant, breastfeeding or trying to conceive
- Women with chronic daily opioid use and any chronic pain or frequently reoccurring pain condition, other than endometriosis, that is treated with opioids for \> 14 days per month.
- Women that are currently using Cannabis based products or have used them within 30 days of enrollment

- Women with chronic alcohol use (defined as \> 3 drinks per day, averaged over one week)
- Women with chronic use of drugs (defined as \> 10 days/month) that cause somnolence/sedation such as benzodiazepines or Central Nervous System (CNS) depressants that are unwilling or unable to discontinue the medications for the washout period and the duration of the study
- Women who are currently taking Clobazam or Valproate and are unwilling/unable to discontinue the medication for the washout period and the duration of the study
- Women with suicidal ideation or uncontrolled depression within the past year
- Known history of or suspected breast cancer on screening physical exam
