THC Absorption?

[beachguy in thongs]

Cigarettes takes seven years.

The longer breath-holding time significantly increased both percent retention of tar in the lung and the pre- to postsmoking rise in blood COHb, serum THC and heart rate, independent of puff volume and number. In contrast, the larger PV (tobacco) had no significant influence on these variables for the same amount of cigarette consumed.

beachguy in thongs Reviewed by beachguy in thongs on 07-30-2006. THC Absorption? I've searched for this and have yet to find a straightforward answer and evidence to back it up. Is THC absorbed in the first 5-7 seconds of inhaling or is this a myth? If it is true, why would shotgunning and hotboxing work? In my experience, I feel it is a myth, however, since so many believe it, I feel as though you know something that I don't. Please Explain. :) Rating: 5

May I ask where you got the piece of information?

And can you explain it in layman's terms?

Without meaning to argue with anyone or start a flame war, I've found that I also get higher when I hold the smoke in for 10 seconds or so versus instantly exhaling (any longer than 10 seconds for me doesn't really increase it though). I've tried on several occasions to prove myself wrong, as I have seen the studies, but I never get as high when I don't hold it in. If I'm still wrong about it, at least I'm high :stoned:

you dont get more high holding it in, you most likely just get a slight headrush from the lack of oxygen.


and I think I know the answer to the hotbox question, the only people who dont smoke when hotboxing a car is non-smokers....they dont actually get high but everyone else gets high so they feel like they are too almost.....when you sober and hanging out with a bunch of people on mush you will act differently and stuff just cause the people that are high get you so excited and stuff...they dont smoke weed so they mistake this new "hyperness" for a high...... hotboxing doesnt get you high man try it out get someone to blow all their smoke in your face and you wont get high lol

Sorry, I must've missed the reference. I'm really not sure exactly, right now, but it's from Entrez PubMed. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi
I searched Cannabis Lung.
I think it was an older study.

Also, I shouldn't have thrown that Tobacco comment in there.

It doesn't mean anything if you consider this study (below)

Effects of varying marijuana potency on deposition of tar and d9-THC in the lung during smoking.

To determine whether smoking more, compared to less, potent marijuana (MJ) cigarettes to a desired level of intoxication ("high") reduces pulmonary exposure to noxious smoke components, in 10 habitual smokers of MJ, we measured respiratory delivery and deposition of tar and delta9-tetrahydrocannabinol (THC), carboxyhemoglobin (COHb) boost, smoking topography, including cumulative puff volume (CPV) and breathholding time, change in heart rate (deltaHR) and "high" during ad lib smoking of 0, 1.77, and 3.95% MJ cigarettes on 3 separate days. At each session, subjects had access to only a single MJ cigarette. On average, smoking topography and COHb boost did not differ across the different strengths of MJ, while THC delivery, as well as HR, were significantly greater (p < 0.01) and tar deposition significantly less (p < 0.03) for 3.95% than 1.77% MJ. Although individual adaptations in smoking topography for 3.95% compared to 1.77% MJ were highly variable, three subjects with the lowest 3.95% MJ:1.77% MJ ratios for CPV also displayed the lowest 3.95% MJ:1.77% MJ ratios for tar deposition. In vitro studies using a standardized smoking technique revealed a mean 25% lower tar yield from 3.95% than 1.77% MJ (p < 0.05), but no difference between 1.77% and 0% marijuana. Under the conditions of this study, we conclude that tar delivery is reduced relative to THC content in a minority of subjects, and this reduction appears to be due to a reduced intake of smoke (decreased CPV) and/or a reduced tar yield from the stronger MJ preparation.

Imagine if they had used 30% THC MJ for this study, as opposed to 3.95%.

In layman's term, let me smoke a bowl.

Hot-boxing and Tuberculosis:
Tuberculosis outbreak in marijuana users, Seattle, washington, 2004.

Matching Mycobacterium tuberculosis isolates were noted among 11 young tuberculosis patients socially linked through illicit drug-related activities. A large proportion of their friends, 14 (64%) of 22, had positive tuberculin skin-test results. The behavior of "hotboxing" (smoking marijuana inside a closed car with friends to repeatedly inhale exhaled smoke) fueled transmission.

back to that other question, how fast does your body get ride of weed tars?

[da haze meister]

i just chill on it...
sometimes ill hold it in for 3, sometimes like 10
but like damn man... it does get me more stoned
even on dank sativa it gives some couchlock... i think cuz CBD and shit are less soluble with the lungs...

It's prob not a 100% sativa, which is why you get some couchlock.

Anyway, guys, let's not dwell on these studies and what not. Everyone has their own way of smoking, as long as we all get high who fucking cares?

I usually hold my hits for 5 seconds because i've read that 95% of the thc is absorbed within that time. I don't have a link, i'm not going to search for a link, I'm just gonna keep on toking and keep on getting high.

From my experiences, holding it in has added effect.
