So many things could lead someone into smoking amongst which are;
- Peer influence borne out of the quest and desire to join in the trending.
- Ignorance: Some guys believes that a real Man must either smoke, womanize or takes to alchoholism. so they are being deceived into smoking.
- Family background also tends to affect some people into smoking. Kid's whose Dad smokes tends to follow suit.
- Profession: A person's type of profession may lead one into smoking. People in the military, touts/Union people in motor parks, People that works in the water all tends to smoke.
These and many more are some of the reasons why people are led into smoking. I haven't really thought of any better benefit of this vice but i know there's a kinda addictive satisfaction it gives people that indulges into such practise.
i know of a friend that claims that he cannot defecate well if he haven't smoked.
