"Systematic reviews of controlled clinical studies of treatments used by chiropractors have found no evidence that chiropractic manipulation is effective, with the possible exception of treatment for back pain.[8] A 2011 critical evaluation of 45 systematic reviews concluded that the data included in the study "fail[ed] to demonstrate convincingly that spinal manipulation is an effective intervention for any condition."[10] Spinal manipulation may be cost-effective for sub-acute or chronic low back pain, but the results for acute low back pain were insufficient.[11] No compelling evidence exists to indicate that maintenance chiropractic care adequately prevents symptoms or diseases.[12]"
Laws and accreditation don't change how the human body works (and, importantly in the case of chiropractic performances, doesn't work). No energy lines to unblock, your humors or bile aren't unbalanced, a wheatstone bridge can't detect alien ghosts and some distant planet's apparent motion from the Earth's perspective isn't causing your misfortune. We're just meat machines no matter which map lines you're inside and a medical professional who can't keep their mysticism and fantasy out of the workplace can not be trusted to maintain their patients' physical or mental health.
