Yes smoking was acceptable in those times. In the army, era mid 1960's in the C rations we were feed in the field. Included a pack of 6 cigarettes, matches, gum, and a small pack of toilet paper. At every rest stop the sargent would shout", smoke em if you got em " as a order to take a break. As I recall cartons of cigarettes were dirt cheap at the PX.
