Chiropractors have the same level of education as medical doctors, and are licensed as primary health care doctors. The difference between chiropractors and medical doctors has to do with how they treat the human body. Where medical doctors rely on external chemical compounds to treat ailments, chiropractors focus on the structurally correcting the internal conditions, which causes the ailments in the first place. Because of this, chiropractic is highly effective in treating a wide range of conditions without resorting to taking drugs.
