Module Description: Substance Use disorders in Older Adults is a growing problem not only in the United States but throughout the developed world. The Baby Boomer generation, born between 1946 and 1964 is turning 58-76 years old this year. This group is presenting with more Substance Use Disorders and need for substance use treatment now. The use of an artificial cut off age of 65 years of age as the definition of elderly or old is somewhat arbitrary and this will be discussed. The module will look at the prevalence, screening and treatment of tobacco, alcohol, opioids, non-medical use of prescription drugs and illicit opioids as well as stimulants and cocaine, marijuana and non-opioid sedative hypnotic agents. A case vignette will drive the CME portion and elucidate the tenants of the module.
