Where is THCa Legal in the United States?

Tetrahydrocannabinolic acid (THCa) is fast-becoming one of the most sought-after hemp derivatives of all-time, particularly in the forms of vapes, flower, and concentrates.  The reason is because these products are heated, thus converting THCa into delta 9 THC.  Basically, THCa exposes a legal loophole, as despite it turning into delta 9 THC, a heavily restricted cannabinoid mostly associated with marijuana, it can exist freely on the market.  But, does that mean that it’s legal everywhere?  Not exactly.  Let’s go over each state to find out where THCa is and isn’t legal in the United States.

Is THCa Federally Legal?

We know it may surprise you, but THCa is perfectly compliant with the Farm Bill that passed in 2018, which made all hemp derivatives legal if they contain no more than 0.3% delta 9 THC.  That means that THCa is legal in any concentration, product form, purchase amount, or possession amount, because tetrahydrocannabinolic acid is ultimately not delta 9 THC, and the law clearly singles out only the latter.  It does not matter that certain THCa products produce delta 9 THC when they’re utilized, like vapes, flower, and concentrates, as when the product is tested, it only contains THCa rather than delta 9 THC.

Which States Have Banned THCa Products?

Now, let’s get into each state’s laws on THCa products, as some states have come up with some restrictions.  Some states require that hemp products contain no more than 0.3% “total THC,” which is a combination of delta 9 + THCa.  Other states have banned specific product types, like flower.  Find your state below.
