In 2014, Tennessee passed HB 2445, which updated the state criminal code to remove industrial hemp from the definition of marijuana. Also in 2014, the state passed SB 2531, which allowed CBD oil to be prescribed to treat intractable epilepsy as part of a clinical research study. A year later, Tennessee expanded the law to allow CBD oil (with 0.9% THC or less) to be prescribed to treat intractable epilepsy by authorized physicians (HB 197).
The state has an industrial hemp pilot program. Marijuana for either recreational or medical use is still illegal in Tennessee.
