does holding in weed smoke get you higher

Debunking The Myth Of Holding A Hit Of Marijuana

The age-old myth of holding in a hit of weed smoke is said to make you feel higher. But does science back up these claims? Read on to find out what holding a hit does to your body.

Surely you have witnessed this numerous times. Maybe you even do it yourself. Firing up a joint, taking a few hits, and holding it in stronger than the vaults at Fort Knox. You proceed to pass the joint along to your friends while holding the hit in, mimicking Houdini’s underwater escape.

It is the standard no-cost approach to getting higher, right? Hold the smoke in for longer, and the body will have extra time to absorb more THC through the lung’s alveoli. Unfortunately, despite the apparent logical reasoning behind this notion, this theory does not hold up.

Air contains approximately 20% oxygen. Our lungs on average can hold 6 litres of air in one breath. When we exhale, the air that escapes our body holds approximately 15% oxygen. We are not all that efficient at absorbing oxygen and expelling carbon dioxide, and that is why we breathe rhythmically and do not hold 6 litres of air for several minutes to absorb as much oxygen as we can in one go.

The same principle applies to smoking weed.


Regrettably, that is not what is going on. The lungs can transfer gas in very small quantities at the nanosecond level. It occurs almost instantly. According to some sources, 95% of all possible THC is absorbed near instantly upon inhale.

If you hold in your toke, you may feel it hits you stronger, but what is really going on is you are depriving oxygen content to your brain, making you feel a little lightheaded. If you add carbon monoxide and toxins from combustion to the mix, this lightheadedness is intensified.


You can quickly test this for yourself. If you smoke tobacco, consider taking a joint-like hit and holding it in as long as you can. You will feel the same tingling or slight dizziness happen, even though there is no weed in the mix.

If you don’t smoke cigarettes, sit on a chair, legs parallel. Grab your legs and put your head between your knees, looking down. Take a few good deep breaths, then exhale as much as you can and hold it for as long as you can. Right before releasing, pull yourself back into normal sitting position as you let yourself breathe. If you do this intensely enough, not only will you feel dizzy, you may even faint! So make sure to do this under the watch of a friend and take it easy.

There is a game where kids induce fainting from oxygen deprivation. Same principal as the chair exercise, they stand back against a wall, exhale, then another kid puts their hand on the victim’s chest, applying slight pressure. In as little as 30 seconds, kids would go lights out, just like when you get a whitey from smoking cannabis.


The more you hold your breath, the more elevated the heart rate gets. Blood is pumped faster to compensate for the low oxygen levels. This has a compounding effect as you hold your breath, since there is no oxygen available. The body starts reacting to this new emergency warning sign. Adrenaline starts getting released to prepare for a flight-or-fight response, which only increases the overall “high” sensation.

Another symptom of oxygen deprivation is the tingling sensation of your skin and face – often also falsely associated with getting extra-blazed.


If you want to get extra high, the answer is pretty straightforward. Smoke more weed. Or smoke stronger strains, or even consider concentrates. If you really want to achieve new levels of psychotropic euphoria, try edibles. But be aware; they will hit you in different ways, and are often quite strong.

Consider vaping and dabbing concentrates. These are the least harmful methods of inhaling THC and other cannabinoids. As there is no combustion happening, you will not breathe in carbon monoxide, tar, and other toxins. With a vape, you will be able to smoke a much larger quantity of weed without the harmful oxygen depriving interception caused by carbon monoxide.

Being that concentrates have very high levels of THC, the same volume of inhaled toke will also contain a much higher concentration of THC, resulting in a bigger and stronger hit.

The old saying “less is more” applies perfectly here. The less you hold the smoke in, the more chances you have to take another toke.

The formula is quite simple. The more hits you take, the higher you will get.

Will holding a hit increase how high you get? We look into what exactly is happening when you hold in cannabis smoke.

Your opinion: does holding in smoke make you higher?

The topic of whether or not holding in smoke increases the effects of the cannabis plant is a popular – and divisive – topic among recreational cannabis consumers.
Read on to see what our community of enthusiasts thinks about this burning issue.

If you are a cannabis consumer yourself, take a minute to recall your first encounters with your favourite plant, however long ago that was. While every experience is different, we are somewhat positive you can confirm there was always a divide on the challenging subject of whether or not one should hold in cannabis smoke. You may even still be regularly debating this while partaking with friends!

This is why Sensi Seeds decided to test the waters and asked its Facebook and Instagram communities the following question.

The results were eloquent, with almost equal parts of believers, and non-believers. Which side turned out to be right? Check out the different stances below, or skip to The Science to get the 101.

Many of our users were convinced that holding in smoke while consuming cannabis results in a stronger high.

M.T.C. – “It’s always worked for me!”

D.M. – “Holding it in your cheeks, false! Holding smoke in your lungs, depends on your tolerance, absorption rate is increased, true!”

C.V. – “Yes, if doing proper circular breathing with a little amount of smoke in your lungs. You’ll get so much more high, rather than just holding it or exhaling right away.”

Depending on the user, various “optimal” numbers of seconds during which smoke should be held in were reported. On the other hand, everyone from this side of the poll seemed to agree on one thing: however long you choose to do it, holding in smoke supposedly triggers a much more powerful result than when inhaling, and exhaling immediately after.

While we can’t exactly say that this is untrue, the reason why this happens is actually not linked to any kind of increase in cannabinoid intake …


J.IXO – “False. It just gets the lining of your lungs kinda screwed.”

W.A. – “Takes only milliseconds for the good stuff to pass through. Only need to make sure you inhale properly and you will be fine and dandy.”

A.L. – “It doesn’t and that’s not an opinion that is fact. That “higher” feeling you think you’re getting is literally just oxygen deprivation.”

As user A.L. confidently asserts in the above comment … the statement presented by our team was false! And it was never a question of opinion: science has proved it.

Indeed, many studies have been published on the topics of THC absorption, breath holding time, and the impact of cannabis smoke on the lungs. Many of them have been conducted in the ‘80s and ‘90s, which presumably explains why most current smokers seem to have missed the memo.

The Science

E.S.T. – “False false false, if you don’t know this by now you’re ignoring the science.”

When inhaled by way of smoking, cannabinoids are transported to your lungs, where they are absorbed by its millions of alveoli. Via them, in a matter of seconds, they make their way through the bloodstream, and eventually to your brain.

The real question hidden behind the one we opposed to our community is the following: how long does it take for the lungs to absorb cannabinoids?

If quantifying the average smoking experience, 3-5 seconds is the threshold after which a crushing majority of the cannabinoids contained in a puff of smoke are fully absorbed by the lungs.

After that, most elements gaining more exposure from an increased breath holding time would be tar, as well as other lung-damaging compounds, not to mention carcinogenic elements if tobacco is part of the equation. There is evidence that some THC accompanies the aforementioned dangerous items, however, in such small quantities, that the health hazard that the rest of the process represents is far from outweighing this gain.

But don’t take our word for it! Here is a small collection of studies that have addressed the issue throughout the years:

Can you smoke vaped weed?

Why is everybody confused?

Numerous users have reported from the “True” side, confirming that the “holding in” method has worked wonders for them. This is very understandable, as several things may lead a consumer to think they are succeeding at absorbing more cannabinoids.


R.L. – “I don’t think so. Holding in smoke does not increase the THC intake, all it does is cut off the oxygen to your brain. This makes it seem like you’re higher but that “high” goes away once the oxygen is flowing to your brain again.”

As per mentioned by this user, when holding your breath in order to keep smoke in, you deprive your brain from oxygen. This state of oxygen deficiency is called Hypoxia. After a few seconds, this leads to a particularly convincing rush of “high”, which can be misconstrued as originating from the cannabis being consumed. As we saw earlier, it is partly true that more THC goes into your lungs in this particular situation. However, the amount of it is so slight, it is unlikely to play any part in the rush experienced.


A “ghost hit” is a puff of smoke that is held in until only an insignificant amount of it is left to exhale. To achieve such results, the smoker needs to hold smoke in for several minutes, breathing occasionally from the mouth or nose while actively keeping the smoke in. This is generally achieved via, well, holding one’s breath, or by practicing circular breathing.

This method is especially popular among those who can’t consume cannabis freely, but have easy access to it (such as young adults), and is generally used to conceal the use of cannabis from others.

This may explain why it is considered an integrant part of the average smoker’s experience. Following such intense oxygen deprivation, the “high” experienced, while almost entirely not cannabis-related, is undeniably impressive compared to your run-of-the-mill inhale-exhale puff. Many smokers are tricked into seeking the same level of high every time they smoke, which results in the misplaced but widely popular obsession around the “holding in smoke” technique.


If you are a beginner, or if it simply turns out to be one of these days, it is possible holding smoke in will make you cough violently at some point. Coughing, while not the most optimal method for expanding one’s lungs, does exactly that. This means that following a coughing fit, your lung capacity will increase, thus offering more surface area for cannabinoids to be absorbed.

However, this is most definitely not the recommended way to increase lung capacity. Instead, opt for breathing exercises prior to consuming cannabis, or work on your cardiovascular capacities!

Vape High vs. Smoke High: What’s the Difference?

Your fellow community members’ advice

J.T. –“ If you inhale nothing and hold it in for long enough obviously you’ll feel a little high, it’s called oxygen deprivation, this is why people say they feel euphoria when drowning or being chocked, it can also give you brain damage if you’re determined enough.”

J.T. is right, and raises an interesting point: if you are excessively committed to experiencing a stronger “high”, this may eventually lead to dangerous incidents. From there, generally speaking, the advice is: DO NOT hold cannabis smoke in. So what to do instead?

You may recall this article stated earlier that 3-5 seconds is somewhat of a reasonable number to link to the process of cannabinoid absorption. BUT – this does not mean you need to “hold in” the smoke for 3-5 seconds. For one, breath holding time is not the sole parameter at play when it comes to the potential of a high.

J.B. – “Depends on THC potency, very low THC levels will be broken down and absorbed through the lungs almost instantaneously.

No need to hold anything in! Pace yourself, and smoke mindfully. If you’re doing it right, a slow inhale-exhale round should take you approximately 3 seconds.

J.D.B. – “It is not the duration of the holding that makes you higher, just the quantity of smoke inhaled.”

That’s right! Inhale more smoke. This does not mean you should inhale bigger hits. Quite the opposite, actually. Because a big hit is fairly high maintenance, you may end up coughing out half of it, or have to hold it in for a very long time in order to handle it without coughing. Instead, take regular-size puffs, and ensure you are thoroughly, slowly inhaling them. Essentially, just proceed with the usual inhale-exhale, only in a slower manner.

D.A. – “The lungs have limited surface area, holding doesn’t make cannabinoids circulate, but rebreathing does.”

As an alternative, rebreathing has at least the merit of being harmless. Rebreathing consists in exhaling smoke, and inhaling it back immediately after. In other words: taking full advantage of one’s own second hand smoke. However, keep in mind that the amount of cannabinoids present in second hand smoke is fairly low.
