What is THCa Flower?

Hot Product on the Market

If you consume Cannabis or purchase Cannabis products, you've likely heard of THCa. Recently, the market has flooded with smokable hemp flower with high THCa content. This has led to a mass influx of questions, concerns, and internet searches. Interestingly, many consumers do not realize they have already been enjoying THCa for a long time! Everything you want to know about THCa will become clear in a few brief moments.

Natural Component of the Cannabis Plant

Similar to THC and CBD, THCa (Delta 9 Tetrahydrocannabinolic acid) is a naturally occurring cannabinoid - the substance of the Cannabis Sativa plant. These cannabinoids bind to our body's receptors. THCa is not a minor cannabinoid, it is found in abundance within the natural flower. THCa can offer relief of inflammation and pain. It may also help stimulate appetite, and treat symptoms of arthritis and seizures.

Practical Application

Rarely is THCa consumed in its raw form. The most important thing to note is that THCa is the natural precursor to THC. While the plant is growing, THCa will "decarboxylate" into THC. The process of decarboxylation also takes place upon the introduction of a heat source, which happens immediately.


The Cannabis plant can be divided into two categories: Hemp and Marijuana. What determines the classification of a cannabis plant is its active Delta 9 THC level. Cannabis plants which have an active Delta 9 THC that exceeds .3% on a dry weight basis are considered marijuana, while plants which Delta 9 THC levels do not exceed .3% are considered hemp. Notice, the law is specifically Delta 9 THC, and not THCa or Total THC (Active THC + THCa). This does not apply to the production of hemp or the cannabis plant, but simply how the harvested crop is classified. The 2018 Farm Bill distinguishes federally legal hemp from illegal marijuana based on concentration levels of active Delta 9 THC levels. Again cannabis plants with less than .3% active Delta 9 THC are considered hemp. So, a hemp bud with THCa levels of 25% and no active Delta 9 THC easily falls within the 2018 Farm Bill’s definition of “hemp” and is legal under federal law.

This is a federally legal hemp flower, containing 25% THCa.



THCa is not psychoactive until decarboxylated into Delta 9 THC over a measure of time, or immediate activation upon a heat source. Shop federally legal flower online at Green Treez Company! Shop Flower
