Cigarettes inhaling is increasing day by day. There should be necessary measures to restrict it. Cigarettes ate nothing but poison. There's no difference between having it and having poison. It's similar to suicide. Such a suicide that not only kills the smokers but also those who are around them! Consuming it every day leads the smokers to the reduction in their life span.
Such things should not be consumed. It reduces the amount of oxygen in blood thereby making the blood impure. Stay away from these!
