What Is THCA Flower?
THCA flower is raw, unheated cannabis bud that contains tetrahydrocannabinolic acid — the natural precursor to THC. When you light a joint, vaporize, or dab the flower, heat converts the THCA into Delta-9 THC, delivering the full classic cannabis experience. Because it tests under 0.3% Delta-9 THC by dry weight, THCA flower is federally compliant under the 2018 Farm Bill and legal to purchase in Wisconsin.

Why Madison Smokers Choose THCA Flower
