how fast does THC enter the bloodstream?

[biojuggernaut]

Is it officially safe to say the obvious that holding in your combustion hits do NOT get you any higher then exhaling the smoke quickly DO to the fact that THC enters your blood stream as soon as possible. What about the other noxious chemicals that get you high? Are those chemicals absorbed equally as fast? How does one's bloodstream absorb THC when it is vaporized? Thanks for anyone who took time to find/provide information to these questions!

I don't have any insight into your question, but that is an interesting question, someone mentioned to me that by the time you can smell a chemical, or substance in the air it's already being absorbed, im sure it depends on the chemical, but for instance if you smell ammonia in the air from cleaning, has it already been passed into your brain?

humm well I would tend to believe time + contact with your alveoli (the part of your lungs that actually does the chemical transfer) would = more absorption.

i don't know how quickly it passes the membrane and enters your system though.

My gf is only a part time vapist, and she only takes 2nd hand hits from me. but even if i hold em in (10-30 seconds) she still gets good and ripped too!

part of the vapor will be trapped in the middle of the lungthings(don't know how they're called in english, those little balls)
and the diffusion also takes a little time, so blowing out immediatly is probably inefficient, but keeping it in very long has not much use either, more efficient would be working on techniques for the exhaling to profit from that trapped vapor, and maybe there's also vapor in the dead space
Ive seen multiple threads on this here on this forum, so seartching would probably yield usefull results

I think the verdict is far from final in this area. People have proven that you can get high from both 2nd hand smoke and vapor (exhaling into a bag, for example, then having someone else inhale from the bag).

There ya go.

I do believe that you absorb from smoke quicker than from vapor, but getting high from exhaled smoke proves that you don't absorb a big smoke hit instantly. As for how long it takes for THC and other compounds to absorb, we'll have to hope that more research studies get done, sooner rather than later.

more then 2nd hand is possible 2... on my birthday last year we were with about 10 people I think, and we sat in a circle around the campfire and passed hookah-hits around the whole circle(one person inhaked from the hookah, gave it trough, that person held it in for a while and passed it to the next etc)
at the end there was still smoke to exhale, I can't judge about the potency tough since we were already really stoned

I cant remember where I read it, but iirc with smoke in the first few moments your are going to absorb as much as you can then your body stops absorbing. It can only absorb so much, which is why people can get high off of 2nd hand smoke. So the absorption from the smoke is almost instantaneous, but you don't absorb all there is to offer in that instant.

95 per cent of what you will absorb is absorbed in the first three seconds. I get that from the Vaporpedia entry on the MFLB. The designers (who I assume wrote the article) state it as fact, and they've nothing to gain from stating non-fact so I believe them. There's a certain amount of THC the lungs can absorb from one rip and holding it in longer doesn't increase this. They also made the point 'visible' vapour is actually not THC - the THC is mingled into that 'mist' which is made up of other compounds. So big thick hits are mostly for show and mimic the visual experience of combustion without necessarily delivering a better high. Parallell with that the common wisdom visible 'vapour' on exhalation is 'wasted'... it seems to me the entry on the MFLB is correct, and there's nothing to be gained from holding it in, except perhaps a rush of oxygen to the brain when you finaly exhale and replenish your lungs, which would put a cherry on the top of any rip, I guess.

No one is actually qualified to answer this. but I do believe that cannabinoids from smoke are absorbed faster then that from vapor, but also I believe that vapor is much more potent and contains more of those cannabinoids.

I won't give you numbers because I don't feel like being questioned on them, but I will give a few generalizations that are pretty sound;

1) Even though there are an ungodly number of variables, there is an equilibrium set up between cannabinoids present in vapor/smoke and transfer saturation at the surface of the alveoili ( i know....spelt wrong). The only way to get more (of the cannabinoids in the vapor/smoke) into your body in as short a time as possible is to force the equilibrium in the direction of going into your body. There aren't too many ways of doing that other than to increase the concentration of cannabinoids in the vapor/smoke or by increasing the length of contact between lungs and inhaled content.

2) How quickly does it enter your bloodstream? Within seconds. Proof; have you ever smoked/vaped some cannabis so powerful that you got higher (and you could feel yourself getting higher) as you inhaled? I suspect that it enters the bloodstream immediately because the biological response of being medicated/high occurs within seconds. You're then looking at a combination of physical/mediated transfer and a mediated/physical response. This would be pretty easy to demonstrate in laboratory conditions. Probably already been done.

However, this extremely quick response allows one to titrate to a desired dosage easily.

Well basically your alveolar sacs in your lungs will absorb the thc and transport the molecules to your blood stream, and they will reach the cannabinoid receptors in your brain pretty fast, so i'd say it shouldn't take very long. I can't explain "creper" highs, but when I vape, I can feel the effects as soon as I blow out the vapor I had been holding in for 10-20 seconds

 

[biojuggernaut]

Have noticed all things said above. thanks for the great insight people. 10-20 seconds? thats is a pretty long period of time.

I just really enjoy holding my hits in for an extended period of time. I can't say whether I get more high holding it for 10-20 than 2-5 seconds, so i don't know. Just a personally preference I guess

 

[djonkoman]

I think I hold part of the vapor also in for 10-20 sec, but I exhale in puffs, I've read that should be the most effective method but I don't know of it really makes that much difference, but I also kind of like that method(I like watching the vapor as I slowly blow it out, and this extends the time I can look at it without feeling the negatives of holding your breath for a longer amount of time, it stills feels relaxed/'natural' without much pressure
