Dear Madam,
Here is my term report on the smoking awareness among the people of Pakistan. It is
estimated that 56% of men and 20% of women smoke. This is an alarming high figure. It is also
seen that 85% of smokers develop this lethal habit from their teenage years. The Ministry of
Health has repeatedly warned against the ill effects of smoking. It even went as far as to publish
its warning on each and every pack of cigarette and banning tobacco adverts. Despite of these
measure, the number of smokers continue to rise each year.
Through this report I have covered aspects like how many people some, their age group,the frequency and the amount of money sent on cigarettes and how many people are actually
aware of the ill-effects of this deadly habit. I have tried to use statistics to understand the
extent of smoking in Pakistan and I have used the SPSS software to aid me in my research.
Thank you for taking time to read my report.
Yours truly

The aim of this test was to verify if there exists a co relation between the monthly income of the
respondent and their monthly expenditure on cigarettes. The test revealed that there is a definitive
significance at 0.01.

8. Conclusion
Our tests have revealed that many smokers are aware of the adverse effects of smoking and most of
them have tried to kick this habit out. But despite this we can see a steady increase in the number of
smokers and their expenditure on cigarettes. This is a very alarming revelation and it means that the
Government should enforce more strict anti smoking laws, like increasing duty/tax on cigarettes and
setting minimum price per cigarettes (so that we dont have 20 pack cigarettes selling as low as rs.20).
Also we need to increase the awareness about ill effects of smoking to the youth so that they are better
educated about the subject.
