Most state medical-cannabis programs use a clinician certification or recommendation rather than a conventional pharmacy prescription for an FDA-approved drug.
Certification is state-specific
States decide which professionals may certify, which conditions qualify, whether a written treatment plan is required and how frequently the relationship must be renewed.
What to bring to an appointment
Prepare an accurate medical history, current medication list, prior treatment information and questions about impairment, interactions and product forms.
- Identification and residency documents
- Relevant medical records
- Medication and supplement list
- Prior cannabis experience, if any
- Specific treatment goals and concerns
Recommendation is not the same as product selection
A certification may authorize program participation without selecting a specific dispensary product. Product labels, potency and delivery methods vary, so patients should seek appropriate clinical and pharmacist guidance where available.
Watch for low-quality certification practices
Be cautious of guaranteed approval, no meaningful evaluation, unsupported medical claims or pressure to buy a particular product. Verify the professional’s license.
