An Evaluation of Diverse Therapeutic Interventions for Substance Use Disorders: Serotonergic Hallucinogens, Immunotherapy, and Transcranial Magnetic Stimulation

Abstract

Substance Use Disorders are a substantial public health concern whose treatment remains challenging. High rates of relapse are in fact a hallmark of drug addiction despite the wide variety of psychotherapeutic and pharmacotherapeutic approaches. This chapter discusses three innovative and controversial therapeutic approaches for Substance Use Disorders that have received considerable attention: the use of classic serotonergic hallucinogenic drugs (LSD and psilocybin), addiction immunotherapy and anti-addiction vaccines, and the use of transcranial magnetic stimulation. These treatments are not necessarily new but are discussed because they represent a diverse set of approaches that address varied aspects of drug addiction. Furthermore, they have an accumulated body of research from which to assess their future viability. For each of these therapeutic approaches this chapter considers the theoretical basis for use, history, status of the literature supporting their use, limitations, and potential applications. While these three interventions represent highly varied approaches to the treatment of Substance Use Disorders, this diversity may be necessary given the complex nature of addictive disorders.
