If you want to find out more about Dianetics and Scientology, the best way to do this is to read an L. Ron Hubbard book on the subject. I personally recommend you read Clear Body, Clear Mind.
This book really helped me with being able to open my eyes regarding drugs. I learned that without drugs effecting me, I could choose clearly. This data is for everyone from hard drug users to sober people. Remember, we live in a society full of chemical toxins that slow us down. Radiation, preservatives, medical drugs -- you can get them out and wake up!
