Inhaled forms act in minutes and fade in hours. Swallowed forms take an hour or more to start and can last most of a day. Pick a form to see its window and what that means for the time you take it.

Taking a second edible because the first one "did nothing" after 30 minutes. Swallowed THC usually needs 30 to 120 minutes to start; wait the full window before deciding.
