How Long Does a Cannabis High Last?


How Long Does a Cannabis High Last?

How long am I going to be high for? Whether you’re a first-time smoker or a seasoned cannabis user, you may be interested to learn how long a marijuana high lasts. Find out why cannabis highs vary from person to person and what affects the duration of your experience.

It’s a good idea to know how long you’ll be high for after smoking weed. Understanding how long cannabis highs last will help you make the most responsible decisions possible about your consumption. So how long will a cannabis high last for you? We all have different bodies with unique endocannabinoid systems, which can make dosing cannabis accurately a difficult task. Determining your dosing points and your reaction to cannabis is a great start to discovering the duration of your highs. 

Becoming aware of how long your high lasts will help you use cannabis more responsibly. Knowing how long your high will last is important if you’re going to be driving soon or if you want to plan a meal around the munchies. Getting to know your highs may come in handy, whether it’s your first time dabbing, you’re trying a new cannabis concentrate, or you’ll be consuming in an open public space like a festival. Every stoner should take the time to learn their average high duration and the effects from various methods of consumption. 

How Long Does a High Last on Average?

The typical duration of a cannabis high is 2 to 4 hours, when smoked or vaped. After 4 hours, the peak of the high will be over and you may feel less energetic or more sleepy than usual.

As a general rule, the maximum time a high should last for is about 6 hours, when smoked or vaped. However, some individuals report feeling the effects for much longer than others. Certain people experience stronger effects from THC than others due to their endocannabinoid system. A small minority of the population has a significant sensitivity to the psychoactive compound from cannabis. This may even cause individuals to experience a weed hangover after smoking.

Taking cannabis sublingually, meaning to drop some type of cannabis oil under the tongue, is a quick and easy method of consumption. The cannabis is absorbed into your blood vessels under the tongue and will be directly transported to the brain. A sublingual cannabis high should last 2 to 4 hours.

On average, the high from consuming edibles will last longer than from any other method. The high from edibles typically lasts somewhere between 4 to 6 hours, or even longer.

Sublingual – 2 to 4 hours

Smoking or vaping – 2 to 6 hours

Edibles – 4 to 6+ hours

Factors That Affect Your High

Why do some highs last longer than others? For starters, cannabis affects everyone differently. Also, various methods of consumption can cause a high to end faster or last longer. Aside from that, many other variables are at play that determine how long a cannabis high lasts.

Method of Consumption

The way you consume cannabis will contribute to the type of high you experience and how long this high lasts. For example, if you orally consume cannabis, it can take 1-2 hours for you to even feel the effects, but it will last longer. Smoking cannabis, on the other hand, produces near-immediate psychoactive effects.

Amount of THC Consumed

This is may seem like an obvious one, but your high will last longer if you consume more THC. After all, THC is what causes your high in the first place.

The more THC your body has taken in, the longer it will take for you to absorb and expel it. Certain strains, concentrates, and products will have a higher THC content than others.

Metabolism & Genetics

Some people may process cannabinoids differently due to genetic variations, differences in their endocannabinoid receptors, or other metabolic reasons. Age, height, weight, and general health will also play a role. The uniqueness of every individual’s body determines the intensity and length of a cannabis high. 

Strain And Cannabinoid Profile

Each cannabis strain has its own individual characteristics and will produce unique effects. Whether you’re consuming a hybrid, sativa, or an indica will have an impact on your high.

The ratio of THC to CBD in certain strains can also affect high duration and intensity. For example, a strain with a higher proportion of THC to CBD will produce a more powerful, long-lasting high.

Environmental Factors

When you’re in an unfamiliar environment, you may feel heightened effects that contribute to the longevity of your high. For example, you may feel the intensified effects of a cannabis high if you have social anxiety and consume in a public place. Your natural anxiety will make the high feel more powerful and long-lasting. You will get the best experiences from cannabis by consuming it in an environment where you feel most comfortable. 

Tolerance & Familiarity

As you use cannabis more often, you may feel that the effects are becoming shorter and less intense. This is because your tolerance is increasing. Now, even though you’re consuming the same amount of THC, you feel diminished effects.

Other drugs and alcohol use may also affect your experiences and expectations. If you develop a high tolerance to THC, you will need to consume more cannabis to experience the same high that you did the first time.

Stay Lifted & Have Fun

Have you ever wondered how long your high will last for? Experienced users, first-time smokers, and every kind of stoner in between should become more aware of their highs. However, keep in mind that finding a strain that gives you a great experience is more valuable than anything else. A fantastic 2-hour experience is better than a 6-hour encounter that you can’t wait to be over.
