5-7 isn't what i would call a "long time" .. 10 seconds? 15? yea.. that's getting a bit excessive.
Bobbong,

I appreciate the link bro. I want those interested to know that I'm not looking to prove or disprove 'any' theory one way or another... I just want the 'truth'

While the link you gave me was very interesting, I would like to see some citations of studies (maybe pubmed?) where scientific tests were done and measurements given.

I'm sure holding anything in your lungs for a long time is bad for you but do you really get the majority of your high from the first 3 - 7 secs? I would just like to see specifically the study, citation, or even an abstract of the study that shows that HUMAN lungs absorb 95% or more of THC within 3 - 7 secs.
