I love evidence based practice. But, the claim in the pipesmagazine blog is not sourced, a google search returns the blog post. Pub-med does not produce any articles whatsoever related to tobacco with pipe and filter in the title.They also claim to absorb 77% of the nicotine and 91% of the tar from the smoke stream, as tested by independent laboratories." I know that was two separate university labs.
I wonder what tests charcoal has undergone and what results ?
Does anyone have a source for this claim?
