Overview of THCA

There is a lot to unpack in this piece, but if you are short on time or just want the highlights, continue reading.

  • The cannabinoid from which THC is derived is called tetrahydrocannabinolic acid, or THCA.
  • THCA alone is not psychoactive, but when heated, it transforms into the psychoactive molecule THC (vaping, cooking, and smoking).
  • The fact that the cannabinoid THCA is not on the list of controlled substances means that it is legal under the Farm Bill. The 2018 Farm Bill makes it clear that hemp and products derived from it, like THCA, are acceptable as long as the finished item has a delta-9 THC content of no more than 0.3% by dry weight.
  • Owing to different interpretations of the hemp regulations, THCA products might be easier to find than THC products in some jurisdictions, thus opening a legal door for those looking for cannabis’ euphoric effects.
  • In which states is THCA permitted? The states that do not support the THCA are far fewer in number: Arkansas, Idaho, Minnesota, Oregon, and Rhode Island.
  • The problem is that laws governing marijuana can be intricate and are frequently revised. It’s critical to keep current on your state’s marijuana laws and to be aware of any potential legal repercussions that might result from using these products.

Federally legal hemp-derived products have a THC content of 0.3% or less on a dry weight basis as of the 2018 Farm Bill. Since THCA is found in raw cannabis and doesn’t produce THC’s psychoactive effects until heated, it falls under this legal threshold when derived from hemp. Thus, THCA derived from hemp is typically regarded as legal in terms of federal law.

Even though the Food and Drug Administration does not expressly forbid it, making it legal on a federal level, THCA is classified as a THC analog, which means that, depending on the laws of your state, possessing it might be unlawful. The states where THCA products are allowed to be sold legally in the US are listed below.

THCA: Where Is It Legal? State By State List

Due to various cannabis laws, the legality of THCA can differ from state to state. While hemp-derived THCA is federally legal, some states have stricter laws regarding all forms of cannabis. To ascertain the legal standing of THCA products, it is crucial to research the laws that apply in your state. Before buying or using any products containing cannabinoids, always make sure you are abiding by the laws in your state.

AlabamaLegalThe state of Alabama has stringent marijuana laws. For instance, you might lose your ability to drive for six months if you are found in possession of a delta-9 THC product.It appears that THCA derived from hemp flower is acceptable as long as it complies with federal law, which legalized all hemp products with a permissible level of delta-9 THC. To prove that a product is made from hemp, carry the label with you at all times.
AlaskaLegalTHCA can be bought and used without any limitations in this state.Alaska was one of the first states to allow adults over the age of 21 to grow up to 12 cannabis plants on their own property for recreational use.
ArizonaLegalIn November 2020, Arizona legalized marijuana for recreational use, allowing adults to freely purchase and use THCA flower and goods containing THCA extract, whether they were made from hemp or marijuana. 
ArkansasIllegalThe only people who are allowed to buy marijuana and its derivatives in this state are those who have a medical license, which is notoriously difficult to get. In the meantime, adults in Arkansas are free to buy hemp and CBD because they are permitted by federal law.In accordance with the initial interpretation, hemp and any products made from it that have a delta-9 THC content of less than 0.3% should also be legal. Even if the finished product has less than 0.3% delta-9 THC by dried weight and is made from hemp that complies with the Farm Bill, the state has altered its hemp laws to address all THC variations.
CaliforniaLegalIn California, THCA is legal to consume. Many of the largest recreational marijuana dispensaries are located in California, which is a cannabis-friendly state. 
ColoradoLegalColorado is a cannabis-friendly state as well, so THCA legal here. Since THCA is not a controlled substance according to Colorado law, adults are free to buy and own it.
ConnecticutLegalThere are no limitations on the purchase and possession of THCA by adults because the state of Connecticut has legalized both medical and recreational marijuana.
DelawareLegalCannabis use for leisure purposes has only recently been authorized in Delaware. Marijuana and its derivatives are still prohibited unless prescribed for medical purposes.As long as it abides by Farm Bill rules, THCA is acceptable. Any THCA-containing products must be made from hemp and have a THC content that is less than 0.3% of the weight of the dried product.
FloridaLegalSince only delta-9 THC is prohibited outside of Florida’s medical marijuana program, THCA derived from hemp is legal there.
GeorgiaLegalGeorgia adheres to the same regulations regarding cannabinoids as the federal government. As long as it comes from hemp and falls under the restrictions of less than 0.3% delta-9 THC by weight, THCA is legally available in this state.
HawaiiGray AreaIf you are at least 21 years old, you may buy hemp-based THCA products that contain less than 0.3% dried weight of delta-9 THC. However, since Hawaii specifically prohibits inhalable cannabis products, you will not be able to legally buy any smokable THCA products.This suggests that the only ways to obtain this cannabinoid may be through THCA tincture and THCA gummies.

Although decriminalized in Hawaii, marijuana and other THC isomers (including those made from hemp) are still not permitted for recreational use. Keep a copy of the product’s labels and third-party lab tests on hand in case anything goes wrong.

IdahoIllegalWhen it comes to marijuana and THC, Idaho has strict state regulations.As long as they contain no THC, hemp and CBD products are permitted under Idaho state law.

This is different from federal law, which allows for a maximum of 0.3% THC. Unfortunately, this means that regardless of where THC comes from, all forms of it are prohibited in this state.

IllinoisLegalIn Illinois, there are no limitations on THCA. Adults 21 and older may use marijuana for both medical and recreational purposes in this state.
IndianaLegalDue to Indiana’s conservative stance on cannabis, it is still illegal to sell and possess marijuana there. It does, however, abide by federal regulations regarding the sale of hemp and goods derived from hemp.There is no specific language in Indiana’s laws that states that all forms of tetrahydrocannabinol are prohibited, nor has Indiana specifically addressed the legality of THCA derived from hemp.

LouisianaGray AreaThe laws governing THC products are extremely strict in Louisiana. In this state, it is against the law to possess any delta-9 THC, including that found in hemp-derived products, unless you are part of a medical marijuana program. The legitimacy of THCA made from hemp is not mentioned.

However, the amount of delta-9 THC in THCA products could affect whether or not they are legal.The state’s views on marijuana advanced after Maryland passed a law in 2019 decriminalizing small amounts of the drug. Concentrated cannabis extracts are still forbidden, though.

What Is THCA?

Raw cannabis buds contain significant amounts of the naturally occurring cannabinoid tetrahydrocannabinolic acid (THCA). THCA does not have any psychoactive effects when taken in its natural state. Yet, when heated (decarboxylated), THCA changes into delta-9 THC, which has intoxicating properties. When consumed, THCA has no sedative effects. Its extra molecular carboxyl ring, which is there chemically, prevents it from interacting with the “high” receptors in the brain. A non-intoxicating substance with potential for a number of advantages, THCA. There needs to be a lot more research done on its properties. THCA is becoming more popular as a substitute for those looking for cannabis’ potential advantages without the psychoactive side effects because it does not get you high.

Hemp vs. Marijuana Flower in the 2018 Farm Bill

The 2018 Farm Bill made THCA and other hemp derivatives with a THC content of 0.3% or less legal. This was a significant step in distinguishing hemp from marijuana, which remains federally illegal. The legislation made it lawful to grow and produce hemp plants as well as hemp-derived goods including CBD, CBN, CBG, and others as long as they adhered to certain standards for delta-9 THC concentration. 

This federal regulation also ignored THC variants, including delta-8, delta-10, and HHC, that do have psychoactive effects. It also didn’t consider the possibility that THCA would be used to circumvent the law because people can create THC by applying enough heat. Despite the fact that marijuana has been made legal for recreational use in many states, some of them have stricter rules regarding THC and marijuana (whether it comes from hemp or not).

Hemp flowers high in THCA can now be cultivated and used to create various products, providing consumers with access to potential health-supporting cannabinoids without the legal concerns associated with marijuana.
