When a THCA pre-roll is combusted, it experiences an important chemical reaction known as decarboxylation. The heat triggers the non-psychoactive THCa (tetrahydrocannabinolic acid) to directly transform into psychoactive Delta-9 THC. It's this conversion that activates the desired highs and euphoria of cannabis. In effect, combust-ing a THCA pre-roll from Killa Kush is what releases its true potential, delivering the experience that users are looking for.
