About

Sean J McGowan is a New York attorney whose practice includes cannabis and marijuana law, based in Hauppauge. Alongside cannabis matters, McGowan handles business formation and transactional work for operators and their investors and capital raising and investor disclosure for cannabis ventures.

Because New York has a regulated adult-use market as well as a medical program, cannabis practice there covers license applications and transfers, compliance audits and municipal approvals, as well as the charges that continue to attach to unlicensed sale and cultivation. Regulation runs through the Office of Cannabis Management. New York is a market still working through its licensing rollout, with significant activity around application disputes and unlicensed storefront enforcement.
