Definitely it's easy to stop smoking only that you need the urge to do it, no ifs no buts. It's in the mind that control our urge to go into vices especially cigarettes and don't be held hostage by your own mind to puff cigarette, you can control your mind by thinking that cigarette kills.
Better still, why not visit the cancer building in your nearest hospital and go straight into the cobalt section and see for your self those pitiful patients suffering from throat, mouth and larynx cancer (caused by cigarette smoking) undergoing cobalt session.
You will be oblige to stop from smoking cigarette once you see those suffering individuals with their necks punctured for them to breath and worse their mouths really smells bad, very bad indeed.
Their mortality rate is very high.
