Indiana Cannabis & Hemp Laws (THCA, D8, D10, HHC, THCP, THCB) — 2026 Update
Indiana remains one of the most restrictive states in the Midwest when it comes to cannabis and intoxicating hemp-derived cannabinoids. While industrial hemp is legal, Indiana law draws a firm line against psychoactive THC compounds, regardless of how they are produced or marketed.
As of 2026, many cannabinoids that are legal in other states are illegal or extremely limited in Indiana. This guide explains what is legal, what is restricted, and what consumers and retailers need to know.
Indiana Cannabis & Hemp Law Overview (2026)
Indiana has not legalized recreational or medical marijuana. Hemp is legal under state law, but only if products are non-intoxicating and compliant with strict THC limits.
Core Legal Principles in Indiana:
- Hemp must contain 0.3% or less Delta-9 THC
- Intoxicating THC isomers are prohibited
- Hemp origin does not override psychoactive effects
- Enforcement targets both retailers and products
Indiana regulators and courts have consistently taken a zero-tolerance stance on intoxicating cannabinoids.
