Heres something small I found http://www.schmoo.co.uk/thclub/methods.htm

Studies done in Australia indicate that 95% of the THC in cannabis is absorbed in the first few seconds of inhaling. Holding in the smoke longer just allows more tar and other noxious chemicals to be absorbed. Take small, shallow puffs rather than deep inhalations.
haha I love the last sentence :jointsmile:
Rad Plane Reviewed by Rad Plane on . long hits I've been smoking for a while, but i'm not too sure if holding in your hits longer ives you a better hit. I've read that it does not matter after 2 seconds or soo, but all of my smoking buddys believe that if they hold it in for 10 seconds it will get them more high. Can anyone shed some light on this for me? Thanks Rating: 5
