Safety
In the words of a New Zealand government study, “Chiropractic is remarkably safe.”

The risks associated with taking a shower are considerably higher than anything we do in our office.
Baseless Concern
Critics, skeptics and those who misunderstand chiropractic often use safety as a way to discourage people from considering chiropractic. Usually it concerns adjustments to the neck. These concerns are baseless.
Chiropractic Wanabes
There just aren’t a lot of recorded instances of chiropractors producing adverse reactions from neck adjustments. When there is a rare newsworthy event, it’s often been at the hands of other practitioners who have taken a weekend course or lack the training and years of education that today's chiropractors receive.
What’s Safe?
Virtually everything has risks associated with it. For example: Statistically, taking an over-the-counter pain reliever is considerably more dangerous than chiropractic care. As is driving your car, taking a shower (slip and fall) or eating at a new restaurant (food poisoning). Relax, knowing these are much riskier than receiving chiropractic care in our office!
Chiropractic Adjustments are Safe
The argument about safety concerns is an example of “junk science” and a perennial favorite by those who have an interest in discouraging people from seeking chiropractic care.
Because of the popularity of this tactic, year after year it has been the subject of countless research projects. The result of these studies show complications from neck adjustments, the supposedly "riskiest" chiropractic procedure, are exceedingly rare:
1972 – One death in several tens of million adjustments.1
1978 – One in 10,000,000 neck adjustments.2
1981 – One in a 1,000,000 neck adjustments.3
1983 – Two to three per 1,000,000 adjustments.4
1985 – One in 400,000 neck adjustments.5
1993 – One in 3,846,153 neck adjustments.6
1995 – One in 2,000,000 neck adjustments.7
1996 – One in 900,000 neck adjustments.8
In other words, cases of serious injury are practically nonexistent. By comparison, it makes the deaths caused by over-the-counter-pain-relievers (more than 1,500 each year) to be considerably more troubling!
Even risk-adverse insurance companies recognize the safety of today's chiropractic care. The premiums for malpractice insurance paid by chiropractors are a mere fraction of what medical practitioners must pay. Chiropractic care is safe.
