PTSD can follow combat exposure, assault, accidents, or other trauma, and commonly involves intrusive memories, hypervigilance, sleep disruption, and nightmares. Veterans make up a significant share of medical cannabis patients certified for PTSD.
Patients frequently report improvements in sleep and nightmare reduction. Clinical research is ongoing and results are mixed; physicians typically position cannabis as one component of care alongside therapy. Note that VA clinicians cannot certify patients, but having a VA diagnosis on record makes the certification process straightforward with an outside physician.
Documentation of a PTSD diagnosis from any licensed provider — psychiatrist, therapist, or primary care — is usually enough for the certifying physician to work with.
