Myth or True, Holding Cannabis smoke in before exhaling?

So i was into an argument with this fellow in my JavaScript class, and he says that holding cannabis smoke in before exhaling has no effect, and that really your just killing yourself by holding your breath. Hence preventing Oxygen from going to your brain. I suppose this could be true but i feel like an extra few seconds makes a difference. Even though THC is instantly absorbed as soon as you take the toke, hence the heat. I still think holding it in may get you that extra bit left? I have been smoking for almost 7 years and I have found it seems to help.(he claims this is from lightness of the head, even though most only hold for a few seconds) I would like to know what you people think though?:stoned:

it defenetly mAKES a difference, specially if you hold it for 2 long and start coughing aLOT, thats like !!!BAM!!!



PS. all ya people who download songs through the internet, download THE CLASH- POLICE AND THIEVES listen to it really high and enjoy it as much as I am right now!!!



peace

It does make a difference, especially if you took a large hit, the smoke makes it's way down your lungs also you can inhale after you held it in for like 3 seconds or you could just let it flow out slow and then inhale some back in.

when i take a fat hit i cant hold it now cause i got my throat operated on like tonsils and adnoids, so it goes through my nose and burns if i hold it in through my both
HAA

I hate to say this, because your all gunner have ago at me, but your all wrong!

THC is the phycoactive compound in cannabis, and is absorbed almost instantly by the lung lining.

Holding it only covers your lungs with the tar, and if you dont hold it in you can almost completly exhale all of the carcenogens (sp?)

THe reason you feel more stoned is because it makes you cough, and as you cough the avioli dialate, which actually doesnt make you higher, just you get higher quiker.

SEriously, dont hold it in unless you want serious health re-procussions...

I think this has been on the home page as a daily factoid too...

I know i am right, no matter what any of you say, because a good friend of mine is lab tech and hes one of the people who have been studying cannabis for the government in England so they can decide where to place cannabis on the class list....

Well I had nothing to support my statement I just felt like holding it in got me higher quicker but I'll take your word on this one.

Whats the best amount of time to hold it in for? I always feel like I waste it when I exhale immediately, like it didn't even get fully in my lungs yet. Like those hits where you open your mouth right after and slowly exhale.

So what your just sposed to inhale like a cig where you just inhale and then exhale no holding in?

i thought it was ideal to take a big hit then just inhale a little normal air, then hold all that for about 3-4 seconds, then exhale.

Well if you all use vaporizers, no one has to worry about tar and plant matter getting into his/her lungs. but yeah, holding it in DEFINITELY makes me much higher than inhaling and immediately exhaling.

There is really a quite scientific way to look at this without all the speculation.

The way the THC in the smoke diffuses into your lungs is a based on simple diffusion principles.

When any gasious substance or gas-particle suspension (smoke) is allowed to diffuse into a material (such as lung tissue), The rate at which it diffuses follows an inverse relationship with an assymptote at 100% absorption. The rate of diffusion (the derivaive of this relationship) is linear and negative sloping, but (important) NEVER 0. It looks similar to this:

http://www.karlscalculus.org/l10_2a.gif

replace the vertical axis with the %thc absorbed, and the horizontal axis with time.

for example: somewhere around 60% of the thc may be absorbed into your lungs in the first second, 20% in the 2nd second, 10% in the third, 4% in the fourth, 3% in the fifth, 2% in the sixth, and so on. The increments get smaller and it will reach 100% total as time reaches infinity.

This may either make no sense or complete sense depending on your inclination in math/physics.

To summarize all of this simply:

-The total volume of THC inhaled in smoke is never 100% absorbed by your lungs no matter how long you hold it in for
-Yes, the longer you hold in smoke, the more THC will be absorbed, regardless of how long.
-The longer you hold it in, the less is absorbed per unit of time. The benefit of holding in the smoke deminishes the longer you hold it in for (but never becomes 0!)

If you want further information and are familiar with differential equations, i suggest reading about Fick's second law of non-steady state diffusion.

This is a good place to start: http://en.wikipedia.org/wiki/Fick's_law_of_diffusion

So ya like Ive been doing, hold in for 3-4 secs then exhale.

i thought that the oxegyn deprivation to your brain from holding it in longer also helps get you high... is this true?

i like to hold it in for like 20-40 seconds or more

I'll do an experiment to help you guys figure this out. Me and a friend will pack a bowl, only he'll smoke it and we'll use a cardboard tube to shotgun it into my mouth and I will only smoke what he shotguns to me. If I get high, that means that there is still THC left and it's worth it to hold it in. If not, I'll just smoke a bowl and get high anyway! I'll be back within 24 hours with the results . . .

im waiting lol jk

But just to be sure, I don't exhale at all.

:p

5-8 seconds is considered ideal. More time always means more THC, but beyond that it's not enough to be worth the effort.

Exhaling immediately is definitely a waste. Not all of the smoke has had a chance to hit the avioli in your lungs, so not all of the THC is out. Coughing also causes the avioli to expand, which helps the THC hit you harder - while this doesn't actually increase the amount of THC in your system, many people find that it helps boost the subjective effects of the high.

sometimes i smoke in my bathroom and i hold it in as long as i can but when i smoke outside i dont hold it in that long and i dont cough when i smoke inside, it does seem like i get higher because i smoke a lot smaller bowls inside to produce minimum amounts of smoke

in conclusion i dont know what to believe

Well Ok then I guess you are Jesus Christ Himself ....lol:thumbsup:

and also dude, why cant you just say what you have to say Lip , No offense but your on the defensive before your even done with your post! "i know im right no matter what any of you say" WTF dude i dont post alot,: but i am in the chat quite a bit and read tons of these and i must say sometimes you come off like really obnoxious and you think you know everything, just a little crit.. not tryin to start a fight. I have nothing against you personally. Peace & Pot:stoned:

ok... i think the reason you get more high... is because CBN and CBD, which gives you a stoney couchlock feeling... are absorbed slower. that is just my hypothesis. cause if i hold it in for 5-8 i definitely get super high... but if i hold it in for like 30 secs i cannot fucking move... off of the same bud.

i always hold it in

Takes about 3 seconds for 99.99% of the THC to absorb into your lungs so holding in for longer then that is just extra tar.

Yea, the guy who explained it using math, and had the link to the graph, said essentially what I wanted to say. Holding it in does get you higher, but the benefits from holding it in more than 3 or 4 seconds are mostly negligible.

I think somebody on these forums said, or I read it in an essay some time, 95% of the THC is absorbed in the first 5 seconds.

Apart from that, no less than 80% of the THC in a joint will get lost no matter how good you smoke it.

I cant guarantee credibility of these numbers :P

I really doubt all THC is absorbed instantly, that would make hotboxing completely worthless.

Sorry dude but no matter what you think you are not entirely right. Because if you were right and 100% of THC was absorbed instantly then second hand smoke would NOT get people high, but it does. and im not talking about the smoke that comes out of the pipe when u stop hitting it or the wasted smoke coming off the joint im talking about exhaling directly into someone elses lungs, and it DOES get them high. You can actually avoid drug tests by doing that, because the THC metabolizes differently if the smoke has already been inhaled. I went to a drug test once and i tested positive for THC and i said But it was just my friends i didnt actually hit the joint i was just around some people who were smoking. she basically shot me down and said sorry bro if it tests positive then you hit the pipe or joint, otherwise if you just inhaled the smoke it doesnt show up on the tests. and its true, my friend gets high like twice a day and is on probation so he has random drug tests and he always passes them even though he gets really high everyday.


So there has to be some THC in the smoke if you exhale right away. I read on a website that it takes 4-5 seconds for 80 or 90% of the THC to be absorbed from the smoke. and usually thats how long i hold my hits for, if im showing off then i will take a huge ass rip and then hold it in until it comes out clear (which for some reason isnt that long anymore, my lungs abosrb all the smoke within like 10-15 seconds but before it used to take like 30 secs min to get the hit to be clear when i blow it out.)


THC can't be INSTANTLY absorbed think of all the surface area on that smoke and even though your lungs are basically a bunch of tunnels and passage ways which has alot of surface area I still dont think it could instantly absorb ALL the THC or even like 50% uness its over a few seconds.


But whatever, believe what u want. I seem to notice a difference between the two techniques but thats just me.

Ya I dont think you lose 80% of the THC in a joint, you definatly loose some because its burning as you hold it and pass it but 80% seems like a lot. But thats y I use pipes more often U get most if not all the smoke.

I'm pretty sure 95% of the THC is absorbed within 5 seconds of inhalation. Holding in hits for longer, or 'ghosting' them creates a placebo effect due to the oxygen deprivation.

if you dont hold it in you wont get as high......anyone who does it should know....fuck knows what the guy who started has been doing for seven years...and whats all this with people getting all anxty about the tar.....if you smoke a plant you cant expect it to be good for you (medicaly ovcourse)... the oxygen deprivation will help but its not a placebo effect....you just get this light headed gidy feeling that is great when your stoned.....

LoL thats the first thing I was told when I first toked, keep the smoke in as long as you can, and we made challenges to see who could hold it in the longest. Tell that guy whats up and if he denies it, then who cares? Its not your loss its only his loss.

I think keeping the smoke in your lungs allows the THC to pass through the walls of whatever absorbs the chemical and so it would be giving off alot more THC into your system every toke you inhale for a period of time. Just inhaling and exhaling doesn't allow all the THC to absorbed, we don't absorb things instantly so allowing the smoke more time to be absorbed is a definent plus.

A vaporiser is definently a plus too if you want more THC and less residue.

dont hold it in because that just makes u dum not high

i also believe that CBD and CBN affect your high, because chronic has been grown for THC content and therefor has smaller ratios of other cannabinoids (CBD AND CBN) so the high from smoking schwag is different from chronic because of this. I think that weed should be grown selectively so that all cannabinoids are increased, that way we would get super high, because there would be large amounts of 3 active psychoactive chemicals.

Oh yeah back to the point, CBN and CBD probably have longer absorption rates than the THC mainly because of the smaller amounts in the smoke. So the extra high you get from holding it in is probably caused by this. But I would like to note that holding it in puts a huge strain on your lungs because it deposits alot more tar and ash (resin) and the hot smoke burns off your cilia (small hair-like cleaning things in your lungs). So its kinda a trade, or you could eat it or vape it and you don't have to worry about those things.

If you smoke a joint REALLY good, pass it quick, don't take huge hits so that you get the joint smoking like a chimney, then said joint will lose about 40% of THC via wasted smoke. I will guarantee that.
