On October 25, 2012, the Institutional Review Board (IRB) at the University of Arizona notified Principal Investigator Sue Sisley, M.D., that they had approved the protocol for our planned study of marijuana for symptoms of PTSD in 50 U.S. veterans. The third and final IRB review took place on October 23. The Food and Drug Administration approved the protocol in April 2011, though the study has been blocked by the National Institute on Drug Abuse since September 2011. We are now preparing to resubmit the protocol and study documents, hoping that approval from both the IRB and the FDA will persuade NIDA to sell us the marijuana needed for the study.
