cause cancer of the mouth, esophagus and pancreas
The study, published in the International Journal of Environmental Research and Public Health , found that in polluted urban areas, reducing air pollution could do as much as completely eliminating smoking would to lower rates of the 12 types of cancer most commonly associated with smoking, including lung cancer, stomach cancer, kidney cancer, bladder cancer, pancreatic cancer, liver cancer, cervical cancer, oral cancer, colon cancer, esophageal cancer, cancer of the larynx and acute myeloid leukemia
Obviously, these are all designed to detect smoke, and as e-cigs produce vapour and not smoke logic would tell you they shouldnt cause any kind of smoke alarm to ring, but even in a real fire situation its not the actual smoke which triggers it as mentioned, its the change to light beams or particle density which will do that
