THCA is found in variable quantities in fresh, undried cannabis, but is progressively decarboxylated to THC with drying, and especially under intense heating such as when cannabis is smoked or cooked into cannabis edibles.
THCA je prisutan u varijabilnim količinama u svežem, neosušenom kanabisu, ali se progresiivno dekarboksiluje do THC tokom sušenja, a posebno tokom intezivnog zagrevanja, npr. pri pušenju kanabisa.
