Dr. Swogger studies both therapeutic and harmful substance use, with a focus on harm reduction. Recently, this work has focused on the individual and public health effects of kratom use. He also studies interventions for individuals whose harmful use of drugs is leading to unwanted consequences, taking into account psychopathic personality and other moderators of successful treatment.

Dr. Swogger has begun another stream of research on the utility of psychedelic psychotherapies for treating a range of conditions. With Robert Horowitz, MD, he is a site-level, co-Principal Investigator on a multi-site study examining the effectiveness of ketamine-assisted psychotherapy for distress in individuals with terminal illness.

As he has for over two decades, Dr. Swogger continues research on causes of violence, suicidal behavior, recidivism, and mental health problems among justice-involved people.
