How long does it take to absorb vapor?

[nucleo]

I disagree.
Vapor in a bag has a much longer time to condense while its sitting in there, leading to an (IMO) greater loss of THC before the user has actually inhaled.
I also find that bag vapes require a larger load than whip vapes in general.

I also don't understand your math, because you didn't show your workings

Here's how I see it:
Lets say that a set amount of weed will produce the same amount of vapor (which I'm gonna call "THC Units"). and for simplicity sake, I'll assume the condensation is the same between a whip and a bag.

Whip vape:
4 hits
25 THC units per hit
12.5 THC units per exhale
50 units absorbed, 50 units exhaled

Bag Vape:
25 hits
4 THC units per hit
2 THC units per exhale
50 units absorbed, 50 units exhaled.

I was actually trying to imply that if there is more air to thc ratio, you wouldn't be exhaling as much thc as you would if you are using a higher thc to air ratio. Just like comparing a bag with more air to thc than a whip which is less air to thc.

Hi, I'm a newly registered member but I've been scaling the threads here at FC looking for the best ways to maximize efficiency with my vapes. I read about 'ghosting' vapor hits on this forum and I do notice a better buzz when I use this method- but i found this study from 1989 that said there was little difference between long and short hits:

Similarly, our lungs absorb oxygen through steady, controlled breaths more efficiently than long ones; I remember this from school. I submit to the consensus that vapor consists 99% of cannabinoids so any visible exhale would be "wasted", because it makes sense logically. But is there any evidence to support this claim?

What I learned in pharmacology was that our lungs will absorb around 95% of the THC within a few seconds. It is not really a question of whether it is vapor or smoke. Our lungs are extremely sensitive and have an incredibly large surface area due to the structure of the alveolar sac, therefore we are able to absorb most of the THC within a few seconds. Holding the smoke or vapor any longer than that only irritates your lungs and damages cilia. Any "visible exhale" can be just waste products like CO2 and also heat.

So, there is no way the lung only absorbs less than 95%? Because if there isn't then, it doesn't matter if we hold it longer than 10 seconds or not, and it doesn't matter how long the inhale is.

And there is no problem exhaling big clouds because in those big clouds there is only about 5% of THC loss.. pretty acceptable to me.

BUT, if the oxigen absorption is better when you take shorter breaths, shouldn't it be the same with THC inhalation?

From my actual experience, I can tell that you can get really efficient with a bag. The idea is to put a very little amount, between 30 and 50 milligrams, and to do a really small balloon on the maximum temp, it gets very thick while tiny enough to be consumed quick, avoiding losses.
I run it through my water tool, in a special way, I pull vapors for just 1/3 of my lung capacity, and still keeping on hitting the tool without the balloon on to clear and get my lungs full. I do it really slow, a hit takes about 20 seconds. I breathe fresh air for at least 40 sec between hits. That way I exhale nearly nothing, and I get medicated from ridiculous amounts.

You know that you're wasting when your balloon gets sticky, theses times I find them pretty neat, even if I didn't changed them for a long time now.

Interesting topic, I see we are mostly talking about THC but what about CBD? I don't know about you guys but I think I've noticed that if I hold my vapor for longer I get a much more sedative (I'm led to believe CBD?) effect off of the load. Could it be that those molecules take longer to absorb?

Has there been any updates on this topic?

 

[beiberhole69]

double post but since a few people liked my last post I'd like to share the info I found (and the other links to .pdfs in this thread don't work)

Here is a study done w/ a Volcano:
https://www.researchgate.net/profil...cannabinol/links/02e7e51583ef3c0fe0000000.pdf

the TL/DR of it is vapor is not like smoke. People were exhaling clouds with 40-50% of the THC still left. Hold your vapor

 

[Wizsteve]

I hold it in till it's all gone may take a few mins but well worth it....

 

[vorrange]

I don't believe that there will be any fundamental differences between the THC and CBD absorbing rate, chemically they are similar and extracted at a close enough temperature between the two.

That study proves nothing. what was measured? Carbon monoxide how did they measured the thc ? They didn't they asked how high they are omg lol.

And also how does the density of the vapor affect time needed ? And is all vapor the same ?? how long to hold in when taking a dab? i say hold your breath in for 3 mins what do you all say?

Very persuasive article relating info from an ‘expert’.

Seems we absorb smoke and vapor through the lungs very quickly. A second or 2 is all that is needed. But inhaling deeply into the lungs exposes more surface area & allows more absorption.

Also if you don’t empty you lungs before inhaling & mix more air with the vapor/smoke, you are less likely to cough.

Gives me something to verify or discount over the next few weeks…..

Experts are not always correct:

"As to smoke or vapor, the answer is: It depends on your goals. Obviously, vapor has less pollutants, so it’s cleaner. (Note: no study has ever linked permanent lung damage to cannabis smoke, probably because the anti-inflammatory effects counter the irritating effects of smoke). But vapor contains fewer terpenes and flavonoids, so the range of the high is limited. It’s clear, but not as powerful. Everyone notices that."

False-
--vapor contains 90% cannabinoids, terps, flavonoids etc while smoked cannabis contains about 10% "goodies". So, no way that vapor has fewer terps etc.
-- not as powerful? The vape high is different cuz you are not inhaling dozens of toxic combustion components----smoking hits you like a toxic bomb.
