Perhaps you should reread that study:
The percentage of total THC delivered to the user is called the THC transfer rate. The unfiltered joint scored surprisingly well in smoking efficiency, coming in second place with a transfer rate close to 20%. The portable waterpipe did slightly better, and the bong slightly worse. The other devices did notably worse. The vaporizers and electric waterpipe did especially poorly, with transfer rates less than one-third that of the top three devices.
Unfortunately, they did not test a typical handpipe or bowl. I'd like to see them match a bowl against a joint. On the other hand, the study DID show joints appear to be healthier for your lungs, oddly enough (at least in terms of tar to THC ratio. It is not immediately clear to me how meaningful that is). But if I was worried about that, I wouldn't be smoking in the first place. Heh.
