When I was in college I started smoking a pipe. Now this was some 40 years ago so thing have changed.
After being drafted into the Army I was sent to artillery school and then to Vietnam. Since we could not get to the rear area and the Post Exchange (store) often we were issued sundry packs. These boxes contained, cigarettes, shaving supplies, soap etc. One of the items was Cherry Blend pipe tobacco. I didn't smoke cigarettes and no one else smoked a pipe I got all of the pipe tobacco in the battery.
Looking at most of the items in the sundry pack we believed that they were originally packed for the Korean war. The pipe tobacco was so old and dry that it would burn almost as fast as the artillery powder. It would take a large slice of apple (when available) and about 3 days before it would become moist enough to smoke.
When I got back for the service I went back to school and was living a my parents and working for them in a ceramic shop they had. At the time I was smoking a chocolate flavored tobacco. It was very smooth with a mild taste. I could never taste the chocolate. The funny part of it was that I would take a break and light up a bowl when there was a class being given. I would smoke watch the class and talk to the students. It was not long into the bowl that the students would all start looking for and talking about chocolate candy. It finally dawned on me that there was just enough chocolate aroma in my tobacco smoke to register in the subconscious but not enough to truly smell.
I could have made a fortune if I had purchased some Hershey bars and sold them during class as I enjoyed a bowl of fine tobacco.
