Many different ways to consume cannabis involve heat to decarboxylateTHCA into THC; common modes include:
Smoking, involves burning and inhaling cannabinoids ("smoke") from small pipes, bongs (portable versions of hookahs with a water chamber), paper-wrapped joints, tobacco-leaf-wrapped blunts, or the like.
Vaporizing, heating various forms of cannabis to 165–190 °C (329–374 °F), causing the active ingredients to form vapor without combustion of the plant material (the boiling point of THC is 157 °C (315 °F) at atmospheric pressure).
Edibles, adding cannabis as an ingredient to a wide variety of foods, including butter and baked goods. In India it is commonly consumed as the beverage bhang.
Cannabis tea, prepared with attention to the lipophilic quality of THC, which is only slightly water-soluble (2.8 mg per liter), often involving cannabis in a saturated fat.
