97% of the thc contained in the smoke (reguardless of peice) is absorbed by your lungs within 3 seconds....

it's pointless... just does more damage to your lungs... and any 'stronger effect' you recieve is purely lack of oxygen and has nothing to do with holding it in...

to give you an idea in numbers of how much 'thc' might be wasted by letting hte hit go after 97% absorbtion.... it'd take roughly 33 hits holding in til 100% absorbtion (which i'm pretty sure is impossible) just to equal one normal hit..

you're not really wasting anything, but your lungs by holding it in... after 33 hits, do you really think that one single cumulitave hit you've gained by holding it in forever is really all that much?

:thumbsup: just let it go man, for your own health... just cuz you smoke, doesn't mean you don't need to completely disregaurd your lungs... be good to them and they'll last you a bit longer..
