This fourth annual SEALS cannabis law discussion shifts focus from speculating on uncertainty to identifying signs of maturation. After more than a decade of state-level adult-use legalization, some doctrines and administrative practices have achieved relative stability, even as the future of federal prohibition remains ambiguous. The session considers which aspects of cannabis law might be called "settled"; identifies accepted practices in licensing, compliance, and enforcement; and explores whether these lines reflect true success or uncomfortable compromise. Invited discussants include cannabis industry and drug policy scholars as well as those working in overlapping areas of administrative, constitutional, criminal, and agricultural law. All participants and perspectives are welcome as we collectively synthesize insights on the transition from responsive to established law.
