Chiropractic Abuse is a very important and timely contribution to the critical evaluation of chiropractic. It provides a most valuable perspective on the education, training, thinking, misunderstandings, wrongdoings and unethical behaviours of chiropractors. Anyone who consults a chiropractor or is considering doing so should study it thoroughly. Preston Long has been a chiropractor himself, and therefore his authority and expertise cannot be undermined by labeling him an outsider. His thoughtful insights and hands-on experiences reflect the very heart of chiropractic. It is this fact that makes this book unique. It would be nice to think that his outstanding and in many ways constructive criticism might contribute to a much-needed and long overdue reformation of chiropractic; but I would not hold my breath. -- Edzard Ernst, MD, PhD.
