MAPS and Ca NORML’s vaporizer research
Fick detta i mejllådan för nån månad sedan:
Here’s a bit of good news about MAPS and Ca NORML’s vaporizer research:
January 21, 2003. MAPS and CANorml sign a contract for a $25,000 protocol study to evaluate the contents of the vapor stream from the Volcano Vaporizer (http://www.vapormed.de).
The purpose of the study is stated in the contract as follows:
This protocol is intended to provide guidance on the completion of an extraction evaluation of emissions produced when marijuana is vaporized using the Volcano; to provide evidence of product efficiency to MAPS, which would subsequently design and seek agency (FDA) approval for the protocol development and initiation of a Phase I clinical investigation comparing cannabinoid blood levels in subjects smoking (i.e. pyrolysis) marijuana versus marijuana vaporized with the Volcano, and to meet the requirements of cGMP: 21 CFR Part 160.
We expect the study to be completed by the end of February 2003.

Disappointingly, waterpipes performed uniformly worse than the unfiltered joint. The least bad waterpipe, the bong, produced 30% more tar per cannabinoids than the unfiltered joint. (…) This suggests that water filtration is actually counterproductive, apparently because water tends to absorb THC more readily than noxious tars. Like the waterpipes, the cigarette filter also performed worse than the unfiltered joint, by about 30%. Researchers speculate this is because cannabinoids are exceptionally sticky and adhere to other solids. Hence, any filtration system that picks up particulates is likely also to screen out cannabinoids.
