We’re in the midst of a nationwide shift in how cannabis is viewed. It’s now recognized as much more than a way to get high. The plant holds serious therapeutic potential. But scientists have only scratched the surface of what’s possible. Because cannabis was federally illegal for so long, research opportunities were extremely limited.
The 2018 Farm Bill began changing that. As long as THCA products are made from hemp and contain less than 0.3% Delta-9 THC by dry weight, they are considered legal.
However, some states have their own cannabis regulations that differ from federal law. Let’s take a closer look.
Is THCA Legal Federally?
According to the 2018 Farm Bill, hemp and hemp-derived compounds are federally legal if they contain less than 0.3% Delta-9 THC on a dry weight basis. This law distinguishes hemp from marijuana based on Delta-9 THC content.
However, the U.S. Drug Enforcement Administration (DEA) argues that THCA does not meet the definition of legal hemp. Because THCA converts into Delta-9 THC when heated, the DEA considers it a controlled form of THC. Despite this stance, the Farm Bill remains the governing legislation, meaning THCA derived from hemp is federally legal at this time.
Federal Age Limits for THCA
The federal government has not set a specific age limit for purchasing THCA since the cannabinoid isn’t regulated at the federal level. THCA derived from hemp falls under the same category as other hemp products, which have no federal age restrictions.
However, state laws take precedence. In most cases, you’ll need to be either 18 or 21 to buy THCA products, depending on local regulations.
Legal Age to Buy THCA by State
Buying or possessing cannabis products, including THCA, as a minor can lead to legal consequences. The greater risk, however, lies with brands that fail to verify customer age, similar to alcohol or tobacco laws.

Can You Legally Grow THCA Flower?
In states where cannabis is legal, you may be able to grow THCA flower, but the rules vary. Cultivation comes with risks, such as decarboxylation during storage, which can increase THC levels beyond the legal limit.
Monitoring Delta-9 THC levels is difficult without professional equipment, and testing can be costly. For most people, it’s easier to rely on expert growers. You can always enjoy ready-to-use THCA products from trusted brands.
Can You Legally Smoke THCA Flower?
Yes, smoking THCA flower is legal as long as it meets the 2018 Farm Bill requirements we outlined above.
Be mindful of state laws, especially when traveling or transporting THCA products. Law enforcement officers may have difficulty distinguishing between legal and illegal cannabis. Additionally, consuming THCA can still cause you to fail a drug test, since it produces Delta-9 THC metabolites.
Wrapping Up: The Current Legality
So, now you know that THCA is legal on the federal level because of the 2018 Farm Bill. However, Hawaii, Idaho, Minnesota, Oregon, Rhode Island, Utah, and Vermont have banned it. If you’re not in those states, you can enjoy THCA products and experience authentic cannabis effects.
