Here is the column that ran in 1972:
DEAR Ann:
How many times has someone asked, "Do you mind if I smoke?" And even though you'd rather not have smoke blown in your face, you say, "That's all right. Go ahead."
New evidence should be called to the attention of the reading public, and here it is.
Recent experiments at Texas A&M University indicate that 30 minutes in a smoke-filled room significantly increases the non-smoker's heart rate, blood pressure and the amount of carbon monoxide in his blood.
A team of researchers at the University of Cincinnati Medical Centre reported that smoke drifting from the burning ends of cigarettes, pipes and cigars contains cadmium, which could be harmful when inhaled by onlookers.
Another research team at Wayne State University in Detroit found that acute illnesses, mostly respiratory, were twice as prevalent among young children whose parents smoked at home than among children whose parents did not.
