THCA is a naturally occurring compound found in the trichomes of the cannabis plant, including hemp.

When THCA is heated, it undergoes a process called decarboxylation, which converts it to THC. This is why when you smoke or vaporize cannabis, the THCA is converted to THC, resulting in the psychoactive effects commonly associated with cannabis use. 

The best part is now they have hemp derived thca flower that is 100% legal!
