Substance Use Disorders and Sleep

There appears to be a significant bidirectional relationship between substance use and sleep disturbances. Sleep disturbances with or without a primary psychiatric disorder can increase the risk of emergence or relapse of substance use disorder. Conversely, both short-and long-term use of substances could lead to acute and chronic disturbances in sleep. This narrative review describes the existing literature on the bidirectional relationships between sleep disturbances and substance use in the context of alcohol, opioid, cannabis, tobacco, methamphetamine, and cocaine use.
