Joanna Zeiger, MS, PhD
Founder & CEO. President of the Board of Directors

Joanna Zeiger, MS, PhD, Founder & CEO. President of the Board of Directors. Dr. Zeiger is an epidemiologist with a strong background in study design and biostatistics, particularly questionnaire-based outcomes studies. Joanna\’s studies took her to Brown University (BA) and Northwestern University (MS). She did her doctoral and post-doctoral work at the Johns Hopkins Bloomberg School of Public Health with a focus on gene-environment interactions in the etiology of birth defects. Upon moving to Colorado in 2003, Dr. Zeiger spent eight years at the Institute for Behavioral Genetics at the University of Colorado Boulder studying drug use and abuse in adolescents; her particular interest was on initial subjective effects to drugs and how they affect long term usage. In 2016, Dr. Joanna was the PI of The Sisu Study which examined mental toughness latent classes in 1250 athletes. The Athlete PEACE Survey, a study for which Dr. Joanna Zeiger was the PI, was completed in late 2018. This study examined cannabis use in athletes. In 2017, The Champion Mindset: An Athlete\’s Guide to Mental Toughness was published by St. Martin\’s Press. A 2009 bike accident left Dr. Joanna Zeiger, an Olympian and former World Champion in triathlon, with severe chronic pain for which she started using cannabis to mitigate symptoms and to aid with sleep. Learning more about cannabis and its medicinal possibilities, particularly in the climate of the opioid crisis, has driven Dr. Joanna Zeiger’s interest to study the plant; her emphasis is on patient outcomes and finding ways to improve the lives of those who suffer with pain.

He is presently PI for the KPSC Clinical Center for the NHLBI funded Vitamin D Antenatal Asthma Reduction Trial (VDAART). He has recently explored the power of administrative data obtained from large computerized electronic pharmacy and healthcare databases to perform outcome studies on severe asthma, the clinical and cost burden of asthma and chronic obstructive pulmonary disease (COPD), chronic cough, and to conduct innovative clinical trials. “Given the disastrous and troubling opioid epidemic, the high prevalence of unrelenting chronic pain, and the lack of highly effective and safe treatments for chronic pain, there is a major public health need for novel effective medications. More definitive research needs to better understand the current use of cannabis for pain in the United States and to provide future evidence through rigorous clinical trials on the role of cannabis in the treatment of chronic pain, inflammatory conditions, and other chronic conditions.”
