Uhhhh yeahhh this is a popular method, and one of the first in making Cannabutter. It's called "Decarboxylation" because you remove the Carboxyl group. This can also done at lower tempatures like boiling water, and it doesn't get rid of terpenes like oven methods do. Simply get a sealable cooking pouch and throw your ground bud in there, then boil for a few hours. Decarbing isn't really recommended unless you're trying to make edibles/tinctures/inhalants.
