Deborah Carmen Mash is an American professor of neurology and of molecular and cellular pharmacology at the Miller School of Medicine and director of the Brain Endowment Bank at the University of Miami.
[5][7] Mash and her colleagues had previously discovered that ibogaine is a prodrug that metabolizes into a psychoactive called 12-hydroxyibogamine (or, noribogaine).
[4] In the late 1990s she provided some assistance to Healing Transitions Institute for Addiction, a drug detoxification clinic in Cancún where physicians oversaw patients' ibogaine treatments.
[8] On eight occasions between 2005 and 2009, she served as an expert witness for the defense in wrongful death claims filed against electroshock weapon manufacturer TASER International.
[11][12] Mash performed post-mortem examinations of the brains of people who were allegedly victims of excited delirium, and reported that most of them showed signs of drug abuse—most frequently cocaine or amphetamine.
