Top Definition
An individual who is addicted to narcotic drugs like heroin, morphine, oxycodone (OxyContin/Percocet), hydrocodone (Vicodin), or other opioids, but can still maintain a normal and successful life.
A functional junkie is a person that can have a family, have a successful career, successful education, and maintain relationships, as long as they have their dope, because once they don't have it, then everything spirals out of control.
