European Industrial Hemp Association (EIHA) new paper on: Decarboxylation of Tetrahydrocannabinolic acid (THCA) to active THC

The Background of this study is as follows: On average hemp food stuffs contain up to 90% of the non-psychoactive THCA. Nonetheless, regulation for THC limits in food often uses total THC = THCA + THC. This leads to an overestimation of the content of psychoactive THC in hemp food. The argument is that THCA can be transformed in THC after heating (decarboxylation). This study analysed how relevant this conversion is in realistic scenarios.
