Smoking tobacco is one of the most common forms of drug abuse and there are serious consequences for your personal health, finances and psychological independence.
Health Concerns
Smoking is the single greatest cause of preventable death globally. Tobacco use leads most commonly to diseases affecting the heart and lungs, with smoking being a major risk factor for heart attacks, strokes, chronic obstructive pulmonary disease (COPD), and cancer (particularly lung cancer, cancers of the larynx and mouth, and pancreatic cancer). It also causes peripheral vascular disease and hypertension.
The effects depend on the number of years that a person smokes and on how much the person smokes. Starting s moking earlier in life and smoking cigarettes higher in tar increases the risk of these diseases.
Financial Issues
Believe it or not smoking is a huge money spender.
If you smoke a pack of cigarettes per day and it costs 8 dollars average then calculations are:
$ 8 x 30 x 12 ≈ $ 3000 per year
So if you start smoking in your 20s you’d spend over $ 120 000 by your 60s – just for the sake of smoking! That’s an excessive luxury spending you don’t really need!
Social Issues
It turns out that smoking brings you more stress then relief and one simple reason for that is you cannot smoke anywhere and anytime. As of July 2011, 27 states have enacted statewide bans on smoking in all enclosed public places, including bars and restaurants. 
For example you have to suppress your need to smoke in places like airplanes, public transportation, office environments and public spaces such as malls, theaters and cinemas.
Also in general non-smokers tend to prefer partners who are also non-smokers.
More Facts:
- Male and female smokers lose an average of 13.4 to 14.3 years of life, respectively.
- Incidence of impotence is approximately 85 percent higher in male smokers compared to non-smokers, and it is a key cause of erectile dysfunction (ED).
- Smoking potentially causes female infertility, and the degree of damage is dependent upon the amount and length of time a woman smokes.
- Smokers report higher levels of everyday stress. Several studies have monitored feelings of stress over time and found reduced stress after quitting.
- Medical researchers have found that smoking is a predictor of divorce. Smokers have a 53% greater chance of divorce than nonsmokers.
How Easy it is To Quit?
Actually to successfully quit smoking may not be as hard as it seems. Smoking cessation can occur without assistance from health care pr ofessionals or the use of medications.
Methods that have been found to be effective include medications, including nicotine replacement therapy (NRT); 
individual and group counseling; books and Web-based and computer programs.
Early “failure” is a normal part of trying to stop. Many initial efforts are not serious attempts.
But the good news about cessation is that in a growing number of countries, there are more ex-smokers than smokers!
That’s why you should not postpone taking measures and quit smoking sooner!
