The Purification Rundown is a fundamental feature of Scientology’s drug rehabilitation program, Narconon, which operates nearly two hundred residential centers around the world. Celebrity Scientologists conspicuously promote Narconon, citing the church’s claims that Narconon is “the most effective rehabilitation program there is.” Kirstie Alley, who served as the national spokesperson for Narconon for a number of years, describes herself as “the heart and soul of the project,” because it had helped break her dependency on cocaine.
