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....

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.....

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 . . .

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:

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.
