Smoking
The Problem
Why do people smoke?
Are people snioking more than they were?
Are more people smoking?
There are many different reasons given for starting to smoke.
- Write down four 'reasons' for starting to smoke.
- Do you think smoking may be harmful? Why?
In this unit we are going to look at connections between
smoking and certain diseases.
Here are reasons some people gave for continuing to smoke.
'My grandad smoked 40 a day for 60 years and lived
till he was 87.'
'I might get knocked down by a bus tomorrow.'
'If smoking is bad for you, why do so many doctors smoke?'
'They haven't really proved that smoking causes lung cancer.'
- Discuss these reasons. Do they make sense?
The Habit
You will need page R1.
Table 1 shows the average number of manufactured cigarettes
smoked per person per day (men and women) over a period of 35
years.
(Source: Statistics of Smoking
in the U.K., Tobacco Research Council)
Table 1 - Cigarette consumption from 1930-1975.
The figures for men from Table 1 are
plotted on page R1.
- Plot the figures for women on the same graph.
- In which year did the average number of cigarettes smoked
by men first reach more than 10 per person per day?
- In which year did the average number of cigarettes smoked
by women first reach three per person per day?
- Compare the smoking habits of men and women up to 1955.
Can you think of an explanation for the peaks in the
graphs?
- Describe the trends in cigarette smoking over the years
1930 to 1975. How does the pattern for men differ from
that for women?
- *In 1975 47% of all men smoked manufactured cigarettes.
What was the average number of cigarettes smoked a day by
a male cigarette smoker in 1975? (Table
1 gives the average for all men, including
non-smokers.)
- *In 1975 43% of all women smoked manufactured cigarettes.
What was the average number of cigarettes smoked a day by
a female smoker?
