If you watch that brilliant AMC series, MAD MEN, which is set in the early '60's, you'll realize that it seemed just about everyone used to smoke everywhere back in the '60's. In fact, I was a wee one in the '60's, & I always thought it was odd that my mother didn't smoke (or drink coffee) like all the other adults. On MAD MEN, one of the characters went to visit the doctor & both doctor & patient lit up! And a pregnant character was also smoking. It was indeed accepted in those days to be expecting & smoking!
