Suzanne A. Sisley MD is an internist and psychiatrist and former clinical assistant professor at the University of Arizona College of Medicine. She was terminated from her position for her advocacy around ending barriers to schedule 1 drug research.

Marijuana research and termination

In March 2014, Sisley's proposal to study marijuana use to treat post-traumatic stress disorder (PTSD) was approved by the National Institute on Drug Abuse. After working at the University of Arizona for nearly eight years in various capacities, she was fired from the university in June 2014, ostensibly because of "funding and reorganization issues." Sisley, however, claims the firing was because of her interest in studying the potential medical uses of marijuana to treat PTSD. Sisley has also claimed that the university failed to provide a location for the trial to take place, and that the University of Arizona was "fearful of the word 'marijuana' and [did] not want... their brand aligned with this research." After she was terminated, the university released a statement saying that they had "not received political pressure to terminate any employee as has been suggested in some media and other reports."

“Why was I non-renewed by UA (fired) in 2014?

I want to stress that, much to the displeasure of AZ Legislature back in 2014, medical marijuana was made legal by a vote of the people in 2010.  

And the extreme right-wing politicians still resented it.  They took their frustrations out on my FDA-approved marijuana research project and my employer - the UA.  

The University government relations folks viewed me as a threat to the overall university legislative-approved budget and complained to President Hart.  And the President told the medical school to get rid of me.

The University of Arizona could not take the political heat from those Legislative leaders mentioned in NY TIMES article.  So they fired me. But more importantly, they deserted the veterans/patients who desperately wanted this valuable study in their efforts to cope with PTSD."

Sisley was initially focused on nonprofit drug development research into potential medical uses of inhaled marijuana and hoped to seek FDA approval of cannabis for Pain/Exit drug to substitute for opioid dependence. But FDA had been impeding this research which enabled Sisley to begin shifting focus into natural psychedelics such as psilocybin mushrooms. Dr. Sisley is licensed by DEA as schedule 1 manufacturer to farm psilocybin mushroom fruiting bodies to conduct human trials. Sisley was awarded a $2.75 million grant from State of AZ in 2024 to evaluate patients with life-threatening illness using whole psilocybin mushrooms.

This schedule 1 license came after her organization Scottsdale Research Institute toppled over a 53 year old monopoly at University of Mississippi thru a series of petitions in Federal Court, and was among 1st Approved by DEA for Licensing to Grow Cannabis for Research.

Dr. Sisley is currently President of Scottsdale Research Institute & Principal Investigator for FDA-approved randomized controlled trials examining safety/efficacy of smoked marijuana flower for treating pain, post traumatic stress disorder PTSD, and opioid substitution.

Sue is striving to put crucial medically active plants/fungi thru entire FDA drug development process to eventually be available in the market as a safer alternative to synthetic pharmaceuticals. Scottsdale Research Institute in conjunction with their 501(c)(3) Field to Healed Foundation is collecting objective data hoping to urge health insurance companies to pay for whole plant botanical medicines similar to conventional pharmaceuticals.
