In Arkansas, 12.5% of licensed physicians certified 3.4% of adults for medical marijuana within two years, with seven high-volume doctors (1,000+ certifications each) showing minimal contact with the patients they certified.

What the researchers found
Medical marijuana was certified for 3.4% of Arkansans 18+ by 12.5% of state-licensed physicians. PTSD and four pain diagnoses were the most common qualifying conditions. Low-volume certifying physicians showed evidence of care coordination — most had seen and diagnosed patients with qualifying conditions. Seven high-volume physicians (1,000+ certifications each) showed limited prior contact with certified patients.
Why it matters
The disconnect between high-volume certifying physicians and their patients raises questions about quality of care. Medical marijuana certifications without proper evaluation may expose patients to risks and undermine the medical framework intended to guide cannabis use.
The numbers in context
3.4% of Arkansans 18+ certified. 12.5% of licensed physicians participated. 7 high-volume physicians: 1,000+ certifications each. Top qualifying conditions: PTSD and 4 pain diagnoses. Low-volume certifiers showed care coordination; high-volume did not.
How the study worked
Analysis of Arkansas medical marijuana certification data linked to physician practice records. Profiled certified individuals, qualifying conditions, and evidence of care coordination between certifying and primary care physicians.
What this study cannot tell us
Arkansas-specific data may not generalize to other states. Administrative data cannot capture quality of clinical encounters. High-volume physicians may conduct thorough evaluations not reflected in prior claims data. Qualifying condition determination is complex.
How to read the evidence
Large state-level administrative dataset with comprehensive physician linkage, but cannot assess quality of actual clinical encounters.
When this study was published
2025 publication.
The bigger picture
As the federal government considers rescheduling marijuana from Schedule I to Schedule III, this study highlights the need for clinical guidelines, provider notification systems, and integration of medical marijuana certifications into health information exchanges.
Questions still open
- Should medical marijuana certifications require documented prior clinical relationships?
- Would integration into health information exchanges improve care coordination?
Common questions
How do doctors certify patients for medical marijuana?
Is medical marijuana properly supervised by doctors?
