THC retailers across Indiana are being warned they could be violating Indiana law by selling cannabis products that contain more than three-tenths of a percent of the chemical Delta-9, which can have an intoxicating effect and may cause some side effects.

Although no Indiana law regulates Delta-9, the Indiana Attorney General’s Office issued an opinion in 2023 defining Delta-8 and Delta-10 as Schedule I drugs.

Violators could be charged with a high-level felony unless they check on what they may be selling.
