Edibles have several benefits over smoking cannabis or inhaling a CBD vapor pen. While it takes a while for edibles to take effect (between 30 minutes to two hours), the result is relief that lasts longer than inhalation. In an edible, the active compound is combined with other foodstuffs. This means that the CBD/THC is released slowly over long periods of time as food is digested. The result is a long-lasting CBD experience. In fact, edibles can last between two and four hours longer than inhaled CBD/THC.
