Found this article as an interesting call for an Acupuncture regulatory board, using rising Pneumothorax rates as an incentive. The article states that they are underreported and they could be avoided with a board of regulation and "safety" needles. Red Orbit Article Here
Aside: I'm sorry but safety needles? It's called use smaller needles. If you're sticking a needle in BL15 or 45 use a freaking half-inch needle if you don't know for sure how deep to go. I don't understand the pneumothorax craze. In America they are also underreported, but mostly because they're being done by Physician Acupuncturists 2 to 1.
