If you smoke cigarettes, do you go outside to smoke?

Back years ago, no one told us that smoking cigarettes was bad for us. they never mentioned lung cancer or second hand smoke. wife and i smoked in our house for years. we did not understand the dangers of second hand smoke, until our granddaughter contracted asthma. the doctors at Vanderbilt advised us that our smoking inside our house, was a contributing factor to our granddaughters asthma. we immediately had the inside of our house cleaned from top to bottom and ceased smoking ever again inside. we make it hard on ourselves to continue to smoke, so we go outside each time. was it the money, was it stupidity on our part or was it just greed that we were not advised long ago, about second hand smoke? we have apologized to our granddaughter many times.
