THCA FLOWER: THCA (tetrahydrocannabinolic acid) is a non-psychoactive compound found in raw or fresh cannabis plants. It is the precursor to THC and is not psychoactive in its natural form. THCa becomes THC through decarboxylation which occurs when the cannabis plant is dried, cured, or exposed to heat (such as smoking or vaporizing). Our THCA flower is hemp derived and contains less than 0.3% ∆9THC and is legal under the 2018 Farm Bill.
