I agree. With no tobacco use in my past, I have no inclination or natural reflex to inhale at all... I can't imagine how sick it would make me. And, as it pertains to retrohaling, I do not plan to do that very often either. No need to expose mucous membranes to smoke any more than "necessary" to enjoy the hobby.The best thing to do to minimize your risk of pipe smoking is to not inhale.
So many people think that a filter makes it safe to inhale. I assure you it does not.
A Pipe smoker's life expectancy is better than other tobacco type users because we do not inhale. Well, that and the fact that one just can't help but be chillaxed and in a nearly meditative state while smoking a pipe. To me the benefits to my state of being FAR OUTWEIGH any risk associated with having tobacco smoke in my mouth and occasionally in my nasal cavity.
