THC in Maryland

In September 2025, the Maryland Appellate Court ruled that delta-8 and delta-10 THC have "always been illegal" in Maryland due to their synthetic nature, even though they may contain less than 0.3% delta-9 THC. The court upheld the Cannabis Reform Act requiring licensing for hemp retailers selling any intoxicating products. Maryland's Alcohol, Tobacco, and Cannabis Commission (ATCC) enforces regulations requiring that all THC products intended for human consumption follow the same packaging, labeling, and manufacturing standards as licensed cannabis dispensaries. Sales of delta-8 or delta-10 THC products to anyone under 21 are prohibited under Criminal Law Article §10-108. The state considers hemp-derived psychoactive products illegal because they are synthetically derived rather than naturally occurring, regardless of federal Farm Bill protections.
