double_huffing
dafremen I was curious as to how many others had come across this method for inhalation of pot.

At some point it occurred to me that I was wasting a lot of pot with each hit. If the smoke that I was blowing out was any indicator..a good portion of each hit was being blown back out into the atmosphere.

I reasoned that the portion of the hit which WAS being used had made contact with the inside walls of my lungs and that the portion exhaled had not.

I tried a few experiments..changing positions during a hit..from upright to reclining and vice versa.

One method I hit upon was the double huffed or double pumped hit. The reasoning behind this method was that at some point, the lungs become saturated with carbon dioxide. No more THC is being introduced to the bloodstream at that point (was my reasoning..more based in guesswork than science I suppose.)

By exhaling only a portion of the hit (until smoke began to appear)...and then drawing in more air...I reasoned..the carbon dioxide levels in my lungs could be diluted...introduction of oxygen would occur and the same hit could have more of its content absorbed into the bloodstream.

Now of course, I've seen the inside of my bong..I can't imagine that the inside of my lungs look much different by now..so there is still the possibility that the walls of my lungs are already covered in resins and therefore the increased effect experienced was due to hyperventilation. That's an alternate cause that I'm willing to deal with.

So to recap...double huffing is the term I'm using to describe taking a hit...then, after exhaling a portion of the hit..taking in more air. Variations should be obvious (triple, quadruple...etc.)

So...any other double huffers/double hit pumpers out there?

somebody used to do that all the time, especially when using airy pipes 080603

another idea! blow it into a bag or balloon and reinhale it whippet-style 080603
