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 1) Verifying things I always thought were true. 2) Teaching me heaps more about the drug problem in our world, and 3) Offering solutions to totally handle the problem. I would like to see a drug-free world and I think this book is dynamite.
