Relapse prevention plans can reduce both the chance and severity of relapses. A relapse is when a person returns to alcohol or other drug use after a period of not using or of controlled use. A plan can help others understand how to support your recovery and help you get back on track if you have a relapse. Relapse prevention plans are based on an understanding of your drug or alcohol use (e.g., previous relapses, triggers, high-risk situations, warning signs) and include strategies for managing potential triggers.
