Here's an interesting passage from the July 2015 minutes of the University of Minnesota IRB Executive Committee:
"The Committee reviewed a report form on Dr. Schulz’s protocol 1408M53023, “Clozapine for Cannabis Use in Schizophrenia (CLOCS)”. This study was approved by our IRB on 12/18/14, but Quorum, to whom the UMN IRB transferred oversight of this study, deemed the submitted protocol inadequate. Quorum indicated that they would not approve the study, and requested Dr. Schulz withdraw it."
This passage raises a number of questions. Why did Quorum IRB reject a protocol that the U's IRB apparently had no trouble with? And more to the point: has this news been passed along to the state legislature along with the periodic reports that the U is legally obligated to provide?
