content: Chiropractic practitioners that stick to the science based treatments are OK. Chiropractic treatments that have been shown to actually work are usually limited to back pain or neck pain. Anything else would be unethical to practice. If they are the "old" chiropractors that actually believe in spinal subluxations being able to cure any ailment like flu, cancer or aids, then they should be considered quacks. It would be dangerous to give a treatment that has no effect and would discourage them from using the real treatment options.
