Yes, there are other ways of consumption that decarboxylate before ingestion. These include:
Vaporizing: Vaporizers heat cannabis to a temperature that allows for the decarboxylation of THCA and the release of THC-rich vapor without the harmful byproducts of combustion.
Edibles: When making cannabis-infused edibles, the usual method will be decarboxylating the cannabis through heat and then adding it into the cooked recipe.
Tinctures: As in the case of tinctures, cannabis might be decarboxylated. This will enable one to consume THC without having to smoke it or vaporize it.
