On January 23, 2009, Gregory Goldstein, Health and Human Services (HHS) Senior Public Health Advisor, Office of the Assistant Secretary of Health, sent a letter to Chemic Laboratories. The letter requires Chemic to do a validation study showing that Chemic could reliably measure various cannabinoids. HHS is suddenly requiring this validation study before it will even review Chemic’s November 6, 2008 reply to the June 18, 2008 Public Health Services (PHS) and National Institute on Drug Abuses (NIDA) critique of Chemic’s January 16, 2008 protocol. In this way, HHS/NIDA avoided responding to the substance of Chemic Labs reply by insisting on a preliminary validation study. This latest message is part of a five and half year tactic of blocking MAPS-sponsored vaporizer research, since a validation study had not been mentioned before in the previous communications and critiques.
In the January 23, 2009 message, HHS provided a list of questions for Chemic Labs to use as guidance for the validation study, but in their own words the questions are not inclusive of all aspects of method validation. Therefore, we could spend $50,000 or more on this validation study and HHS could claim that we did not meet all of the requirements and could request additional expensive validation data, all before reviewing the vaporizer protocol itself, which would only cost an estimated $25,000.
What makes this especially frustrating is that a validation study isn’t truly necessary for the sort of academic study we’re seeking to conduct. A validation study is more appropriate for developing the Volcano vaporizer as an FDA-approved medical device, which MAPS isn’t seeking to do. We’re exploring collaborating with Dutch scientists from the University of Leiden, who are already studying the constituents of the vapors produced by the Volcano vaporizers. We may perhaps be able to conduct a cross-validation study at less than half the cost of the validation study.
We are wary of conducting a validation study, or even a cross-validation study, without HHS/NIDA having reviewed and approved the vaporizer protocol itself. Well get back to HHS after we determine if we can make a case for a cross-validation study, then well ask for the vaporizer protocol itself to be reviewed and approved first before we spend money on any sort of a validation study.
