The difference is that pipe tobacco is soaked in various scents and flavors. I used to smoke a roll your own cigarette called A100 that was soaked in vanilla. People didn’t care that I smoked around them because it smelled like a pipe.
I never smoked and can’t stand the smell of cigarette smoke but will admit that some pipe smoke is pleasant. I used to live in Richmond, VA. and in some sections one could smell tobacco being dried in barns and it too had a pleasant aroma.
I had an Uncle Buck who looked just like a hard bitten old West cowboy tho he was a Florida farmer. He rolled his own from a Prince Albert can and it always fascinated me watching how expertly and fast he rolled those cigarettes, his final act a quick swipe of the paper on his lip to make it stick.
