Many fires happen when people are sleeping. Often times because they fall asleep with a lit smoking device in the bed with them.
This poses immediate danger to not only themselves but to anyone living in that building.
Smoking outside ensures that this does not happen. It will also improve the indoor air quality of the home.
Indoor air quality improvement can reduce breathing issues and asthma reactions.
Only smoking outside can also reduce the amount that you smoke on extreme weather days. Improving your overall health.
