Dr. Abisheak Sharma studied pharmacy and pharmacokinetics in India before coming to the United States to research under kratom expert Dr. Bonnie Avery. He now researches kratom with Dr. Christopher McCurdy at University of Florida as part of the Translational Drug Development Core. Dr. Sharma addresses the concern with kratom and other drug interactions, improved chromatography methods of identifying kratom alkaloids, research on kratom plants being grown by University of Florida, and where we are with kratom and human clinical trials.
