The treatment of substance use disorders has always been challenging because multiple neurotransmitters mediate addiction. However, with smoking being the leading cause of preventable death and the recent opioid epidemic in the United States, the search for novel solutions becomes more imperative. In this review, we discuss the use of antibodies to treat addictions and highlight areas of success and areas that require improvement, using examples from cocaine, nicotine, and opioid vaccines. Through each example, we examine creative problem-solving strategies for developing future vaccines, such as using an adenovirus vector as a carrier, designing bivalent vaccines, stimulating Toll-like receptors for adjuvant effects, and altering the route of administration. Our review also covers passive immunization alone to override or prevent drug toxicity as well as in combination with vaccines for more rapid and potentially greater efficacy.
