During his fellowship, Dr. Abrams spent eight months working in the retrovirology laboratory of Harold Varmus, M.D. during the time that the first cases of AIDS were being diagnosed. He subsequently returned to the clinical arena where he was one of the original clinician/investigators to recognize many of the early AIDS-related conditions. He conducted numerous clinical trials investigating conventional as well as complementary therapies in patients with HIV including therapeutic touch, Traditional Chinese Medicine interventions, medicinal mushrooms, medical cannabis and distant healing. He is considered to be a pioneer in the investigation of inhaled cannabis, having conducted studies funded by the NIH and the University of California Center for Medicinal Cannabis Research. His interest in botanical therapies led him to complete a two-year Fellowship in the Program in Integrative Medicine at the University of Arizona in December 2004. He co-edited the Oxford University Press textbook in Integrative Oncology with Andrew Weil, M.D..
