Is THCA Flower Legal In Connecticut?

No, THCA flower is not legal in Connecticut because of the state’s total THC testing requirement for finished hemp products.

To put it simply, THCA flower is illegal in states that have implemented total THC testing laws for finished hemp products. Under SB 6699, Connecticut tests hemp-based products for a total THC concentration of no more than 0.3% on a dry-weight basis.

This requirement makes products with a high THC concentration unlawful hemp, including THCA flower, delta 8, delta 9, and delta 10 THC items. 

In addition, high-THC hemp products and synthetic cannabinoids are classified as cannabis under Connecticut state law and are legally sold by verified licensed retailers and dispensary operations. 

The new law redefines hemp as a crop with a total THC concentration of not more than three-tenths percent on a dry weight basis. 

Those who want to use THCA flowers in Connecticut should be wary of the laws surrounding the cannabinoid and distinctions between hemp and cannabis or high-THC hemp products.

Is THCA Flower Legal Federally?

THCA flower is legal under the 2018 Farm Bill if its delta 9 THC levels don’t exceed 0.3% by weight.

If the THCA flower contains above 0.3% THC pre-harvest then it would be considered federally illegal to consume. 

This requirement is imposed by the USDA’s Interim Rule, which requires states to test their hemp crops for the total THC levels, calculated as the sum of THC and THCA (0.3% THC + 87.7% THCA). 

Therefore, if the total THC levels of the hemp flower are low pre-harvest, it’s considered hemp. The USDA has no oversight over finished hemp products, so the only thing that matters federally is the delta 9 THC levels.  

Where To Buy THCA Flower?

What is THCA Flower?

THCA flower is smokable hemp flower with high THCA levels and low delta 9 THC levels. This type of hemp flower provides the typical marijuana experience because THCA converts into THC when heated (decarboxylation). 

Once heated, this flower creates a psychoactive experience. So, the user can expect to experience the mind-altering effects of this product and adjust the dosage accordingly. 

If the flower contains 25% THCA, that’s the amount that’s going to convert into delta 9 THC when consumed. That’s a pretty high dose, so beginners should consume based on their tolerance levels.

Are Both Delta-9 THC And THCA The Same Thing?
