California statute and program

The Medical Marijuana Program (MMP) is the operating authority for California patient certification. The authoritative legal text is: California Health and Safety Code Division 10: Uniform Controlled Substances Act (cannabis provisions). The program portal is at Medical Marijuana Program (MMP).

What the evidence says about cannabis and Endometriosis

Endometriosis is a chronic estrogen-dependent inflammatory disease in which tissue histologically and functionally similar to the endometrium grows outside the uterus. Common implant sites include the pelvic peritoneum, ovaries (where they form endometriomas), uterosacral ligaments, rectovaginal septum, bladder, bowel, and (less commonly) thoracic and extra-pelvic sites. The implants respond to cyclical hormonal stimulation, producing local inflammation, fibrosis, adhesion formation, and pain.

For the full evidence base, including the NASEM tier, randomized trial summaries, and symptom-domain breakdown, read the mmjnow Endometriosis page.

How to qualify in California

The Medical Marijuana Program (MMP) requires the following registration steps for a Endometriosis patient (or any qualifying diagnosis):

  1. Get a written recommendation from a California-licensed physician. Under the Compassionate Use Act (Cal. Health & Safety Code §11362.5), any California-licensed physician (MD or DO) in good standing may issue a written recommendation for medical cannabis. California uses the broadest practitioner-discretion standard of any state — any condition for which the physician determines marijuana provides relief is eligible. The physician’s written recommendation alone is sufficient legal documentation; no state ID card is mandatory.
  2. (Optional) Apply for a county Medical Marijuana ID Card through the MMICP. For patients who want a state-issued ID card (recommended for travel, workplace protections, and reduced taxation at dispensaries), California maintains the voluntary Medical Marijuana Identification Card Program (MMICP) administered through county health departments. The patient applies in person at their county health department with the physician recommendation, a California driver license or state ID, and proof of residency.
  3. Pay the county MMICP fee (typically $50–$100, plus Medi-Cal discount). County MMICP fees vary by county but typically run $50 to $100 annually for self-pay patients (e.g., Los Angeles County is $100, San Francisco $103, San Diego $77). The MMICP includes an automatic 50% fee reduction for Medi-Cal beneficiaries under SB 420. The card is valid for one year and renewable. The physician recommendation alone (no MMICP) costs only the physician’s fee, but does not exempt the patient from cannabis excise tax at retail.
  4. Purchase from a California dispensary (medical or adult-use). Patients with either a current physician recommendation or an MMICP card may purchase from any of California’s 1,200+ licensed cannabis retailers. Medical patients with an MMICP card are exempt from the state’s 7.25% sales tax on medical cannabis (under SB 34) and may purchase up to 8 ounces dried plus 6 mature plants under the Compassionate Use Act — substantially higher than the 1-ounce adult-use limit. California does not honor out-of-state medical cards; visitors aged 21+ can purchase from adult-use retailers with a government ID.

ICD-10 code

A certifying physician documenting Endometriosis for the California medical cannabis program will typically record ICD-10 N80.9 or SNOMED-CT 129103003 in the patient's record. The state registry does not itself collect ICD-10 codes in most programs, but the physician's chart is the audit trail if the certification is later reviewed.

Frequently asked questions

Does California list Endometriosis as a qualifying condition for medical cannabis?

Not by name, but California permits physician discretion. Under Medical Marijuana Program (MMP), a certifying physician can add a condition like Endometriosis on a case-by-case basis when the physician judges that the patient would benefit from medical cannabis. This is different from a state where the qualifying-condition list is fixed in statute. Whether a particular physician will certify Endometriosis depends on the physician's training, the strength of the patient's documentation, and the practitioner's reading of the available evidence — evidence is described as limited (a small number of supportive studies, often underpowered or focused on narrow symptom domains). Patients should expect to bring full diagnostic records to the certification visit.

How do I get a California medical marijuana card for Endometriosis?

Step one is finding a physician licensed in California who is registered with Medical Marijuana Program (MMP) and willing to evaluate Endometriosis cases. Step two is collecting your records (diagnosis documentation, treatment history, and the ICD-10 code your physician will use) and bringing them to the certification visit. Step three is the physician's certification through the state registry, followed by the patient registration application, state fee, and waiting period before the card is issued. California does not honor out-of-state cards, so the certification process has to originate inside the state. The state minimum patient age is 18; minors generally require a parent or legal guardian to act as caregiver. The authoritative source for the current process is the Medical Marijuana Program (MMP) site at https://www.cdph.ca.gov/Programs/CHSI/Pages/MMICP.aspx; the state updates fees, forms, and physician registration rules periodically.

What does the evidence say about cannabis for Endometriosis?

For Endometriosis, evidence is described as limited (a small number of supportive studies, often underpowered or focused on narrow symptom domains). The mmjnow condition page for Endometriosis lays out the current evidence base, including the citations underlying that evidence tier — typically the National Academies of Sciences, Engineering, and Medicine consensus reports, federal agency guidance, and peer-reviewed reviews. Evidence quality is independent of state law: a state can list a condition for which evidence is limited, and a state can decline to list a condition for which evidence is strong. Patients deciding whether to pursue medical cannabis for Endometriosis should review the underlying evidence (linked on the condition page) and discuss expected benefit, dosing, and risk with a clinician familiar with both Endometriosis and cannabinoid pharmacology. Cannabis is not a substitute for evidence-based first-line treatments for Endometriosis; the evidence position above describes whether trial data supports its use, not whether it should replace standard care.
