does thc absorb only in your lungs? or in your whole body/blood stream and shit?? like, if i take a huge hit and hold it in for as long as possible, is that any different than exhaling it after a few seconds? i've heard thc absorbs instantly, and was wondering about the inhaling the exhaling a little the inhaling the exhaling a little that routine and if that helps u get any higher?
through my many tests, no you do not have to hold the smoke in, i've gotten high for the past 8 years, and the last 3 i've always smoked, as i would a ciggarette... inhale, hold it for a couple of seconds then exhale, if i feel the need to aslo be lightheaded the i will spin around while taking my hit. you do not need to hold it the magical 17 seconds... but there is alot of major controversy over what's right and what's wrong, so you will hear alot about it, and it seems about half and half 50 percent say no, 50 say yes. there's also alot of 'myths' you'll hear about marijuana and other drug related things, when in doubt ask, but remember this general rule 'if it sounds to stupid/unbelievable to be true, then there's a 99% chance it's bullshit.

i've heard people try and tell me that weed doesnt have a tolerance, i think thats bs., wonders of yalls thoughts on it...i dunno i smoke soooo much and feel like im barely even high, but also it could be just cause im always smoking so im used 2 it...im thinking about quitting for a couple days, i've been going pretty damn strong for about 3 1/2 -4 years
yes, you can build a tollerance, and it's rather quite easy for some people, and others have a natural tollerance to it, all you have to do is just take a break... don't smoke any weed (or in any other way consume cannabinoids) for a couple of weeks, a month at most and it will go away, i guess it's natures little way of saying "use it to enjoy, not to live".
