My experience mirrors pretty much what Rockdoc has described. Pop lasted only until 67 the victim of Camels and Pall Mall's since age 13. I started smoking as a soph in high school but only lasted a couple of years...My attempts at chewing always ended in breaking out in a cold sweat and the dry heaves smile
I worked for years in a drafting room where smoking was the norm. The buddy next to me smoked a strange shaped briar pipe stuffed with something call County Cork (Court)? if memory serves me correctly. Smelled great tasted like schiznit the only time I tried it.

Dodging lions and wasting time.....
