No, there is no specific testing readily available to assess the endocannabinoid system. To apply for a card in California or other states, you need to have one of the qualifying medical conditions specific to that state. For instance, in California:
Cancer
Anorexia
AIDS
Chronic pain
Spasticity
Cachexia
Persistent muscle spasms, including those associated with multiple sclerosis
Seizures, including, but not limited to, those associated with epilepsy
Severe nausea
Glaucoma
Arthritis
Migraines
Any other chronic or persistent medical symptom that substantially limits the ability of the person to conduct one or more major life activities (as defined by the Americans with Disabilities Act of 1990) or, if not alleviated, may cause serious harm to the patientโs safety or physical or mental health
