Regulatory and Legal Factors

Factor	Impact
FDA Approval (2016)	Validates safety and efficacy, facilitates prescribing, fosters market stability
Prescription Restrictions	Schedule II status limits some use; but ensures controlled distribution
State-Level Cannabis Laws	Varying acceptance; may influence off-label and compounded formulations
International Regulations	Limited licensing outside the U.S., constraining global expansion

Implication: Regulatory status offers both opportunities for growth and constraints due to controlled substance classification.
