Understanding these differences is crucial for both recreational and medicinal users in selecting the appropriate method of consumption to achieve desired outcomes.
Duration of Effects: Smoking Cannabis
Smoking cannabis is characterized by the inhalation of smoke or vapor from burning plant materials. When cannabis is smoked, THC enters the lungs and is quickly absorbed into the bloodstream, allowing effects to appear almost immediately, typically within minutes. The peak effects are usually felt within the first 10 to 30 minutes after consumption, with the overall duration of effects lasting between 2 to 3 hours. This method is favored for its rapid onset, which allows users to gauge their tolerance and adjust consumption accordingly in a short period.
Duration of Effects: Consuming Edibles

In contrast, edibles involve consuming cannabis-infused products such as baked goods, candies, and beverages. When cannabis is ingested, THC is absorbed through the digestive system and metabolized in the liver where it is converted into 11-hydroxy-THC, a potent psychoactive form of THC. This process results in a delayed onset of effects, typically taking 30 minutes to 2 hours to manifest. However, the effects of edibles are generally more prolonged and can last anywhere from 4 to 8 hours or longer, depending on the dose and individual metabolism. This extended duration makes edibles particularly useful for medicinal users who require long-lasting relief but can pose challenges for those unaccustomed to managing the potent and sustained effects.
