In general, it is likely that the high from an edible will last for a few hours. The authors of a review article note that the effects from edibles last about 6–8 hours. However, it is not uncommon for the high to last up to 8–12 hours if the person is sensitive but only about 4 hours if the person has a higher tolerance.
Edibles containing THC cause a similar high and feelings of relaxation and euphoria as smoking the compound. The high will vary based on the type of cannabinoids in the edible and the overall potency.
Individual tolerance levels will also play a large part here. People who are not used to cannabis products may feel the effects more strongly and for much longer than a person who regularly uses cannabis products, if they take the same dose. Tolerance levels will also fluctuate depending on how much cannabis a person has smoked or ingested within a period.
When trying out a new edible, it is important to start with a low dose to see how the body responds. With edibles, it is easier to take an excessively high dose and feel negative side effects than it is with smoking.
The National Institute on Drug Abuse note that edible use has caused an increase in emergency room visits. The reason may be that people who are inexperienced with edibles take too much, causing concerning symptoms.
People with faster metabolisms may feel the effects quicker, as the body can digest and process the edible faster. Eating an edible on an empty stomach may also lead to faster acting effects, as opposed to eating an edible with other foods or just after eating a meal.
For some edibles, such as hard candies or suckers, absorption may begin while the person sucks on them, and, therefore, the effects may appear faster. One study notes that hard candies may kick in within 15–45 minutes, whereas other edibles can take 60–180 minutes.
That said, anyone who has eaten an edible and does not feel the effects should wait for at least 2–3 hours before deciding to eat more or use other cannabis products. Everyone is different, and the effects may simply take longer to manifest in some people.
Edibles are cannabis-infused foods or drinks that deliver cannabinoids such as THC and CBD to the body through the digestive system. Learn more here.
