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 to understand what drugs can do to a person both physically and mentally. It also gave me hope that something can be done about the effects and the addiction to drugs. I would recommend this book to anyone who wants to know more about drugs and how to fight them effectively.
