Yes, Delta 9 THC is legal in Oklahoma under specific conditions.
Delta 9 THC derived from hemp with a concentration of 0.3% or less on a dry weight basis is permitted under Oklahoma’s hemp laws, aligning with the 2018 Farm Bill. The Oklahoma Medical Marijuana Authority (OMMA) oversees compliance, while the Oklahoma Department of Agriculture, Food, and Forestry (ODAFF) regulates hemp cultivation and testing. However, Delta 9 THC from marijuana remains illegal unless prescribed under the Oklahoma Medical Marijuana Program, with strict penalties for unauthorized possession.
