• Different types or strains of cannabis can produce different effects.
  • Your biological makeup, along with the chemical makeup of the cannabis you’re ingesting, will ultimately dictate how long a cannabis high will last.
  • Depending on the amount of THC consumed, an edible high can last upwards of nine hours, with the peak generally lasting from one to three hours.
  • As a cannabis high wears down, the more euphoric aspects typically wane and sleepiness replaces them.
  • If you’re experiencing a particularly intense high, it’s important to remember that a) this, too, shall pass, and b) cannabis is not lethal.

Cannabis serves a wide variety of purposes in the modern world, with new medicinal uses and products appearing every day. But for the majority of marijuana users who come to the plant recreationally, the goal is still to experience the cannabis high. 

Marijuana highs can facilitate a wide variety of sensory and psychological effects, including mild reverie, euphoria, increased sensory awareness, and some therapeutic benefits. But if you’re a new or less experienced user, you’d want to know: How long does a high last? What duration are you committing to when you smoke a bowl, eat an edible, or take a dab? 

The Science Behind How Long a High Lasts: Everyone is Different

Much of your reaction to cannabis, whether it be therapeutic or the duration of the high it produces, will depend on your own biological makeup. Different types or strains of cannabis can produce different effects. One variety may produce a more intense high, or one that lasts longer than another. But the same plant can also produce different effects in others.    

Out bodies interact with cannabis by way of the endocannabinoid system (ECS) — the series of receptors, lipids, and enzymes that help the body maintain internal balance and regulate several bodily functions. When cannabinoids, compounds indigenous to the cannabis plant such as THC and cannabidiol ( CBD), interact with the body, they produce an effect by binding to cannabinoid receptors, where they are then broken down by enzymes. Our cannabinoid receptors have genetic variations from person to person, which in turn can alter the effects of cannabis, including the duration of intoxication. 

How Long Does a Marijuana High Last?

So, how long does weed last? There are several factors that determine the answer to this question, but the primary driver on the cannabis high duration is the method of cannabis consumption. Your own biological makeup, along with the chemical makeup of the cannabis you’re ingesting, will also determine how long a cannabis high and potential side effects will last. That being said, the rate of THC blood saturation through to the eventual expungement of THC from the body provides a general window of duration in most people, which varies depending on how cannabis is being ingested.

When smoking cannabis, the onset of the high is nearly immediate and THC levels peak within the first 30 minutes to an hour after inhalation. The high from smoked marijuana can last up to several hours, though the intensity will generally decrease after the first hour or so. 

Cannabis edibles are a whole different story. As edibles are absorbed through the digestive system and THC is metabolized through the liver, it takes anywhere from 20 minutes to 3 hours for the onset of effects. Depending on the amount of THC consumed, the amount of time an edible high can last upwards of 9 hours, with the peak generally lasting from 1 to 3 hours.

When dabbing concentrates, the onset of effects is also nearly immediate, but the duration depends largely on individual tolerance. Those who dab high-THC concentrates often may feel the effects wearing off within 1 to 2 hours, while someone entirely new to dabbing may be wiped out for the day.  

What Does Being High Feel Like?

The specific qualities of a cannabis high will change over time, regardless of the form you take. Similarly to how long a weed high will last, you can expect the specific qualities of a high to change from person to person, and from cultivar to cultivar. Most cannabis cultivars bring with them a general list of qualities that most people experience from them, from hunger to cerebral stimulation, or creativity to couch lock. 

Some cultivars will quash anxiety, while others will increase anxiety. As the high wears down, the more euphoric aspects typically wane and sleepiness replaces them. Again, all of these effects depend on the chemical makeup of a given cultivar, as well as your genes. 

How Much Weed Does it Take to Get High?

The amount of weed needed to feel high also depends on several variables. THC is the intoxicating component of cannabis, and though other cannabinoids play a role in either contributing to or enhancing the cannabis high, the THC percentage of a cannabis product will impact how long you’ll be high when you consume it. However, the method of consumption is an even bigger determining factor. For example, the effects of eating a 50 milligram edible will last longer than smoking a 0.5 gram joint with 20% THC.  

THC percentages don’t tell the whole story, but they do provide a general idea of what a user should expect with flower or concentrate products. In the case of edibles, instead of THC percentage, the key factor to potency is the quantity of THC in the product, which is typically measured in milligrams. 

Weed You Feel vs. Weed in Your System

How long you stay high and how long weed stays in your system are two very different things. As drug tests are looking for THC metabolites, it can take upwards of a month for the compounds to completely leave your system, depending on body mass index (BMI), metabolism, frequency of use, the potency of the product, and genetics.

How to Bring Down Your High? 

If you’re experiencing a particularly intense high, it’s important to remember that it shall pass, and cannabis is non-toxic. No deaths from a marijuana overdose have ever been reported. For those who want or need to come down from a particularly intense high as quickly as possible, there are several tactics that may prove effective, such as taking very deep breaths, ingesting black pepper, hydrating, taking a cold shower, and consuming CBD oil, which may be able to counteract the intoxicating effects of THC by way of the entourage effect.  

How to Increase the Length of Your High

The higher the amount of THC, the less cannabis needed to achieve a high. If you want to know how to increase the length of your high, you can either smoke weed again, opt for the longer-lasting intoxicating effects of an edible, or consume cannabis products with higher levels of THC.
