    Lahore, Pakistan

    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

    1. Questionnaires for the report

    In order to gather the data for my research I prepared a form and then distributed it to my

    from a group of 30 smokers.

    Q.1 Age of the respondents

    Q.2 Monthly income

    Q.3 Do they smoke regularly

    Q.4 How much do they spend on cigarettes

    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.
