How Long Do You Stay High After Smoking Cannabis?

One of the biggest uncertainties for new smokers is exactly how weed is going to affect them. And so the question every new smoker will ask is this: How long do you stay high after smoking weed? Smoking cannabis brings on the psychoactive effects of THC virtually immediately. That’s why the answer to how long you stay after smoking weed has a lot to do with how long THC stays in your system. But the comedown is a slower process. There are a couple “phases” to the comedown effects of cannabis. So answering “how long do you stay high after smoking weed,” depends partially on your definition of “high.” The wearing-off effect of smoking cannabis tends to release your mind first, with your body slowly trailing behind.


The amount of time you stay high for the first time is going to be different than someone who smokes frequently. If you smoke often then you probably already have a good idea of your tolerance. If you’re just starting out then assume your tolerance is very low and your high will likely fall on the lengthier side of the spectrum.

Amount Consumed

The more you smoke, the longer your high will last. If you’re a beginner then start very slowly. Take one hit at a time and wait a minute or two between. It’s better to take your time and know your limits then to create an uncomfortable situation for yourself.


High-grade weed will contain higher amounts of THC than low grade. So, potency needs to be in your mind when considering how much you should smoke.


If you smoke without eating, your high will last longer. Eating can help to shorten the time you’re high after smoking, or if you accidentally got too high.

When inhaled, tetrahydrocannabinol (THC), the primary psychoactive in cannabis, saturates the brain within minutes. Full effects of the herb can often be felt in a mere quarter of an hour. After that, the experience starts to mellow out and will wind down over the course of the next one to three hours. If it’s your first time then it could last longer. People who smoke habitually could stay high for as little as 30 minutes. So, I guess the full range would be anywhere from 30 minutes up to 4 hours, but 2-3 hours is typical for a casual smoker.
