Volcano Vaporizer Research Protocol Resubmitted to HHS

On January 16, 2008, MAPS Volcano vaporizer research protocol was resubmitted to HHS for the required scientific review by the National Institute of Drug Abuse–Public Health Service (NIDA-PHS). The submission included three supportive letters from peer-reviewers (see 1, 2, 3), confirming the scientific merit of the study and urging NIDA-PHS to approve it. The goal of this study is to gather further information about the chemical constituents that are contained in the cannabis vapor stream.
