I was tooling around some websites and found a link to one that sells bongs…er…water pipes. The site claims that up to 80% of tar and carcinogens are removed from the smoke when smoking from a bong. Upon visiting other sites, I have seen this same claim, though the percentage varies from 40% to 95%, depending on the site.
What I want to know is this: Where do they get the data to make such a claim? Is it simply a marketing ploy to get people to buy something that they think is a safer alternative to cigarettes or regular pipes, or has there been an actual scientific study that has concluded that bong smoking is safer?
Some of the other “advantages” touted on several sites that sell bongs claim that the smoke is cooled by the water and does less damage to the throat and lungs, less irritation to mucuous membranse in the lungs, etc. etc.
Has the AMA been testing bong hits and failed to release the study, or what?
