Brian Joslyn

Brian Joslyn is a cannabis and marijuana law attorney based in Columbus, Ohio. Joslyn earned a law degree from Thomas Jefferson School of Law and has 13 years in practice. Alongside cannabis matters, Joslyn handles financial and regulatory offenses, including the banking and money-movement exposure cannabis businesses face, cannabis charges that remain prosecutable even in a legal state, such as sales without a license and cultivation over the plant limit and impaired-driving cases, which are contested in legal states because per se THC limits do not track actual impairment.

Ohio regulates both adult-use and medical cannabis, so legal work in the state runs from licensing and local approvals through packaging, advertising and seed-to-sale tracking rules, alongside the criminal matters that still arise around unlicensed activity and possession above the legal limit. The Division of Cannabis Control administers the state program. Ohio stands out as a newer adult-use market layered onto an existing medical program.
