The National Association for Chiropractic Medicine (NACM) was a minority chiropractic association founded in 1984 that described itself as a "consumer advocacy association of chiropractors".
 It openly rejected some of the more controversial aspects of chiropractic, including a basic concept of chiropractic, vertebral subluxations as the cause of all diseases.
 It also sought to "reform the chiropractic profession away from a philosophical scope of practice and towards an applied science scope of practice."
 It stated that it was "dedicated to bringing the scientific based practice of chiropractic into mainstream medicine" and that its members "confine their scope of practice to scientific parameters and seek to make legitimate the utilization of professional manipulative procedures in mainstream health care delivery."
 "While the NACM is focused on furthering the profession, its primary focus is on the rights and safety of the consumers."
 The NACM was the object of much controversy and criticism from the rest of the profession.
 It quietly dropped out of sight and its demise apparently occurred sometime between May 30, 2008 and March 6, 2010.
