Rather of taking in oxygen in the morning, a buddy of mine smokes carbon monoxide. Upon questioning, he asserts that smoking first thing in the morning is a more beneficial way to begin the day.
When you ask a smoker while he is indulging in such act, they have so much to tell you about their reasons for smoking. Some say it gives them inspiration, some say it makes them not to to think of their problems and sorrows, as if they will be free from such after the light goes off. I have witnessed some smokers who go to defecate while smoking and according to him if he doesn't indulge in that while defecating then he won't be able to pass his waste. So you see that the government has a role to play in this by regulation how people can smoke because it also has some health challenges like you have mentioned. I think the rate of smoking is higher now especially among the young and youth.
Those smokers ha made it to be a habit for themselves that if they don't smoke while deficating, they feel they will not be able to bring out the waste product. Those smokers that wakes up from bed in the morning, first thing that they do is to smoke, have also made it a habit. Addiction is what controls their rate of smoking.
Smoking tobacco is dangerous to our health, and that has being a warning from onset. The government can only give awareness of the negative effects of smoking but cannot force anyone not to smoke. However, there are some benefits to smoking which only the smokers can tell you about.
Yeah it is just an habit that people have developed and use it as an excuse like they won't survive if they don't take it. Human beings have a way of making themselves use to something depending on their choice. So it is a choice that someone has chosen to smoke and they leave it if they are lucky to be alive and sensible or reasonable enough to meet what incident thar will force them to live smoking which could be a result of health issues especially. There are people who leave it because of pressure from the family especially the wife but I have not seen or read any benefit that is attached to smoking cigarettes.
