You see if one-person smokes, everyone in your surroundings will smoke, regardless of whether they are the one holding the cigarette or even in the same building. In a multifamily building, the families with nonsmokers are affected just as much as the ones that have smokers in them. Smoking puts those people at so many risks. Children and adults are at risk for a list of chronic and fatal diseases. So if you don't think secondhand smoke will give your loved ones the "unheard of' diseases," you now know that it can cause cancer. Would you really put your loved one's at risk for getting cancer or even death just for a second of euphoria?
