Tennessee’s new restrictions on THCA products officially took effect today, marking the final piece of a hemp regulation law that has been rolling out since the start of the year. Under Tennessee House Bill 1376, THCA is now classified as a precursor to Delta-9 THC rather than a standard hemp product, closing a loophole that had allowed high concentration THCA items to be sold legally across the state.
Most parts of the bill, including new tax rates, age restrictions, penalties and licensing rules, went into effect back on January 1. Lawmakers delayed the THCA portion of the law until July 1 specifically to give business owners time to adjust before the ban hit. Despite a petition that gathered more than 1,500 signatures asking lawmakers to reverse course, the law moved forward as scheduled.
The issue traces back to how THCA interacts with THC, the compound responsible for cannabis’s psychoactive effects. According to the Tennessee Traffic Safety Office, THCA converts into THC when heated or burned, something state regulators did not account for when they first wrote hemp rules. That oversight left a gap in the law that allowed THCA products to be sold with little restriction, and the new legislation is designed to close it.
So what’s still legal? Hemp and marijuana come from the same plant species, but under Tennessee law, marijuana specifically refers to cannabis containing more than 0.3% THC by dry weight. As long as a product stays under that threshold, THCA remains legal to buy and sell in the state. That means low concentration items like certain lotions and gummies can still be sold, while higher concentration versions of the same products are now against the law. Beverages with up to 15 milligrams of THC per serving are also still permitted.
Other cannabinoids that remain legal under the same concentration limits include Delta-8 THC, Delta-10 THC and THCV.
Buying these products also comes with new restrictions. Every legal sale must happen in person, and buyers must show valid ID proving they are at least 21 years old. Online orders, shipping and home delivery of THCA products are now completely prohibited in Tennessee.
Bringing products in from other states carries its own risks. Missouri and Virginia are the nearest states where marijuana is fully legal, but transporting THCA or similar products into Tennessee can result in a Class A misdemeanor charge. Tennessee remains one of 19 states where individuals can still face jail time for cannabis possession, according to the Marijuana Policy Project. A Class A misdemeanor conviction can carry up to 11 months and 29 days in jail, a fine of up to $2,500, or both.
Repeat offenders could face steeper criminal charges, including potential felonies, while business owners caught violating the law risk losing their license or being forced to shut down entirely.
