Abstract
Various aspects of this disclosure relate to methods to lower the activation energy of the cannabinoid decarboxylation reaction by performing the decarboxylation reaction in the gas phase. In some specific embodiments, the method relates to the decarboxylation of a cannabinoid performed in a short-path distillation apparatus or a thin-film distillation apparatus.
