Kirstie Alley's first experience with the Church of Scientology was when she joined a Narconon program in 1979 to get over cocaine addiction. Narconon bases its techniques on Scientology beliefs and practices.
In 1999, Source magazine identified Alley as an OT VI.
"The one thing that was really cool about L. Ron Hubbard was that he really got the concept that if people united, and not in some airy-fairy way, but if they united and they put their, you know, muscle and brawn together and they worked really hard, you could create a better civilization."
"To tell you the honest-to-God truth: without Scientology, I would be dead. So, I can personally highly recommend it."
