How Long Does A Cannabis High Last?

June 15, 2020

One of the first questions a new or inexperienced cannabis user might have is how long does being high from cannabis last? Every person is different, and the length of a weed high will depend on a wide variety of factors. The duration of your high generally depends on how you individually react to cannabis, to the type of cannabis consumed, to the method you used to consume it.

When Does A Cannabis High Start?

Cannabis highs can start almost instantly or take as long as an hour to set in. The amount of time it takes for a high to start will again depend on your individual body’s reaction but is also tied closely to how you consume it.


Time: Near instantly

Dabs are sticky oils of concentrated cannabis, made from extracting the THC and other active ingredients of cannabis into a potent wax, shatter, or oil. The extract is heated to extremely high temperatures (usually with a blowtorch) and the resulting vapor is then inhaled through a purpose-built dab rig. People who dab their cannabis will likely feel the effects of a weed high the most quickly, with the high setting in almost instantly due to the high concentration of THC. Because of the high concentration of THC and the complex process, dabbing is probably not the best method for first-time or beginner weed users.

Smoking or Vaping

Time: 2-10 minutes

One of the most common methods for enjoying cannabis is smoking. There are a wide amount of options for people who wish to smoke their cannabis, from rolling papers or cigar wraps (joints or blunts or pre roll) to glass hand pipes (bowls) to glass water pipes (bongs or bubblers). Instead of these methods, which rely on combusting cannabis, some users prefer to vaporize their cannabis.

Weed can be vaporized as a flower, wax, or oil, and there are a variety of devices that can be used, from portable pens to large machines. People who smoke or vape their cannabis will have a slightly delayed reaction but usually start to feel the effects anywhere from 2 to 10 minutes after smoking or vaping.


Time: 30-60 minutes

If you would prefer not to take in cannabis through your lungs, eating edible forms of cannabis might be a better alternative for you. Cannabis edibles are foods and drinks that have been baked or otherwise infused with cannabis/THC. Edibles come in a range of varieties, including gummies, chocolate, candy, cookies, brownies, beverages, and more, so be sure to pick whichever sounds best to you.

Those who prefer to eat their weed as an edible will have the longest wait time, usually having to wait half an hour to an hour before they feel the high start. The delay is caused by the THC being absorbed into the bloodstream via the stomach rather than via the lungs, like with smoking, vaping, and dabbing.

How Long Does the High Last?

The duration of effects can last anywhere from 2 to 10 hours. The length of a high is dependent on a multitude of different factors, including:

  • How much cannabis you ingested or inhaled
  • How much THC was present in the cannabis ingested or inhaled
  • Your body weight and body fat percentage
  • Whether you have a slow or fast metabolism
  • If you’ve eaten or not
  • Your individual tolerance level

The length of the high will also depend on the ingestion method.


Time: 1-3 hours

The effects of dabbing weed will peak almost right away, and the duration is between 1-3 hours. However, if you are using an especially high THC concentrate, you could feel the effects for up to 8-10 hours.

Smoking or Vaping

Time: 1-3 hours

The effects of smoking or vaping cannabis will generally peak approximately 10 minutes after ingestion and the duration is anywhere from 1-3 hours, though they may last up to 8 hours if you are using a high percentage THC strain or concentrate.


Time: 2-10 hours

The effects of edibles are the slowest to take effect but the longest-lasting, usually peaking approximately 2 hours after ingestion and lasting up to 10 hours depending on how much THC was used to make the edible.
