As the cannabis landscape continues to evolve, more consumers are asking questions about THC-A—what it is, how it works, and most importantly, where it’s legal. If you’ve been eyeing LITTO’s premium THC-A products but aren’t sure if they’re allowed in your state, this guide is here to clear things up.
What is THC-A?
Tetrahydrocannabinolic acid (THC-A) is a non-psychoactive compound found in raw cannabis. Unlike THC, which gets you high, THC-A doesn’t produce psychoactive effects—until it's heated. When exposed to heat (like from smoking or vaping), THC-A converts into Delta-9 THC, the compound responsible for that familiar high. This process of heating and conversion is called decarboxylation.
Because THC-A is found naturally in hemp and cannabis and is non-psychoactive in its raw form, it exists in a legal gray area depending on state laws.
Is THC-A Legal Federally?
Thanks to the 2018 Farm Bill, hemp-derived products containing less than 0.3% Delta-9 THC are federally legal. Since THC-A itself isn’t Delta-9 THC, it can technically fall within the bounds of legal under federal law—as long as the product remains compliant when tested pre-decarboxylation.
However, states have the final say when it comes to regulating cannabinoids. So while THC-A might be federally compliant, its legality can vary widely across the U.S.
