Fun Fact!

Pipe Tobacco is almost never inhaled by pipe smokers if they never smoked cigarettes beforehand, and pipe enthusiasts are more anal about natural tobacco and unnatural additives.

This is one of the difficult parts of reading up on lung cancers between both groups. I couldn't find any studies pointing directly at "pipe and only pipe smoking", as the population pools for testing people dwindled rather quickly by the late 1980's since pipe smoking was mostly gone outside of hobbyists.

I'd pair this up with vaping/snus in the harm-reduction camp if that's true. I wouldn't consider any type of smoke entering your body as entirely harm-free... or vapor, or nicotine for that matter.
