Most often, the teenagers adopt this habit just because of the company they enjoy. Sometimes, they take a puff from their friend’s cigar. Later on, they develop the habit of smoking as an indispensible part of their lives. With the passage of time, the followers of this bad habit turn into chain smokers. It must be kept in mind that smoking is a toxic habit that may develop lungs’ cancer. Moreover, the other toxic chemicals like arsenic, carbon Monoxide, methane, acetic acid, nicotine, butane and cadmium present in cigarettes are also highly damaging for health.
