NATIONAL ALCOHOL AND
OTHER DRUGS SURVEY
THE SMOKING BEHAVIOUR OF
CANADIANS
PREFACE
This
report is the second in a series concerning the results of the National Alcohol
and Other Drugs Survey. It contains
estimates of tobacco consumption among Canadians age 15 and over. Statistics Canada carried out the survey on
behalf of Health and Welfare Canada in March of 1989. The survey covered a total of 11,634 Canadians age 15 and over,
who answered many questions concerning their consumption of alcohol, tobacco
and other drugs, in particular the quantities involved, habits of consumption
and the circumstances and atmosphere surrounding consumption. Other questions
dealt with health problems and with the social and economic problems caused by
the abuse of alcohol, prescription and over‑the‑counter drugs and
illegal drugs. The survey also asked
people what could and should be done to prevent such problems. All respondents were given the assurance
that they would remain totally anonymous and that their answers would be
confidential.
The
results of the survey provide a solid basis which will be used to assess the
importance of the problem caused by alcohol and other drugs among Canada's
adults.
The
information contained in this report should be taken into account in developing
programs and measures in Canada. It
should foster dialogue and debate among people working in the field, provide a
basis for other research and above all give Canadians the facts they need to
make judicious decisions regarding the consumption of alcohol, tobacco and
other drugs.
Although
the National Alcohol and Other Drugs Survey is impressive in scope, it does
have its limitations. For example, the
survey excludes some groups, such as teenagers under 15, the homeless and
people in institutions. Moreover, it
was only possible to study a small number of the thousands of psychotropic
drugs and other substances that are currently available in Canada. Various surveys relating to these important
issues will be undertaken in order to complete the general picture.
Research
in drug abuse in Canada is in its infancy, and proper documentation on the
nature and extent of the problem is still lacking. This Survey fills many of the gaps in our information, and
prepares the way for the development of effective measures in the long term.
v
The
National Drug Strategy
The
National Alcohol and Other Drug Survey is part of the program of the National
Drug Strategy and of the National Strategy to Reduce Tobacco Use in Canada.
The
National Drug Strategy, initiated in 1987, has been developed through extensive
consultations among the federal, provincial and territorial governments, non‑governmental
organizations and toxicologists.
The
federal government has committed $ 210 million over five years to improve
existing programs and to fund the activities of five federal departments.
The
objective of the National Drug Strategy is to reduce the harmful effects of
addiction on families and communities by taking a balanced approach to the
problems of supply and demand in a Canadian context.
The
National Drug Strategy is based on a proper balance between educational and
preventive measures on the one hand, and actions of interdiction and coercion
on the other. Its underlying assumption
is that the best way to reduce the incidence of drug addiction in the long term
is to attack the problem at its source:
supply. Seventy per cent of
National Drug Strategy resources are devoted to priority areas.
When
the National Drug Stategy was launched, five federal departments received
financial support to take steps for which Health and Welfare Canada assumes
general responsibility. However, the
overall strategy calls upon several federal departments. Some programs, which were already under way
when the Strategy was first implemented, have not received additional
funding. Other anti‑drug programs
have since been set up or are under development. All are partners in the National Drug Strategy on the same basis
as the provinces, the territories and agencies that receive federal assistance
to carry on the war against drugs.
At
the present time, the partners of the National Drug Strategy include 14
departments and agencies of the federal government, all the provinces and
territories and hundreds of non‑governmental organizations.
National
Strategy to Reduce Tobacco Use in Canada
Smoking
is the major avoidable cause of disease, disability and death in Canada. Every year, more than 35,000 Canadians die
of diseases associated with tobacco use.
The
National Strategy to Reduce Tobacco Use in Canada is based on the principle
that actions taken to combat smoking will be more effective if all levels of
government and non‑governmentalal organizations work together.
vi
In
May of 1985, the federal Minister of Health and Welfare and all the provincial ministers
of Health in Canada agreed on the need to adopt a comprehensive approach if the
real desire is to fight against tobacco use in Canada. Eight national organizations working in the
health field also endorsed this approach.
The
position paper of the National Strategy to Reduce Tobacco Use in Canada lists
seven major ways of dealing with the issue of smoking: legislation; access to information;
accessibility of services and programs; dissemination of anti‑smoking
messages; support for community‑based initiatives; and coordination of
policies and research.
The
National Strategy is intended to create a feeling of solidarity in dealing with
the many initiatives that are currently being implemented to fight smoking
throughout Canada, and to take advantage of the excellent programs already in
place, in order to give more scope to the initiative.

HIGHLIGHTS
.
In 1989, approximately 6.5 million Canadians, or 32 % of the population
15 years of age or over, were cigarette smokers. About 33 % of men and 31 % of women were smokers.
.
The highest rates of tobacco consumption, namely 35 % and 37 %, are
found in the 20‑54 age group.
Rates are lower among teenagers (23 %) and among older Canadians (19 %).
.
In the 15‑34 age group, women consume tobacco as much as men, but
the rate of consumption among older individuals is higher for men.
.
Tobacco use is higher in Quebec (35 %) and in the Maritimes (33 %), and
lower in British Columbia (28 %). For
men, rates of consumption vary considerably from region to region, but for
women there is little regional variation except in Quebec, where the rate is
high.
.
The rate of tobacco use decreases as the level of education increases. Individuals who have a high school diploma
or less are more likely to smoke than people with a university education.
.
The rate of consumption among those earning $ 60,000 or more per year is
one third lower than among those who earn less than $ 30,000.
.
Managers, students and retirees are less likely to smoke (23 % to
29 %). The highest smoking rates
are found among blue collar workers and people looking for work (41 % and 42
%).
. For young adults and for older individuals, tobacco consumption
is higher among Francophones and lower among those whose first language is
neither English nor French. There are
no differences by language for smokers in the 35‑54 age bracket.
.
In general, one quarter of Canadians smoke 1 to 10 cigarettes per day,
62 % 11 to 25 cigarettes, and 10 % smoke 26 or more cigarettes. Men between 34 and 54 years of age are the
biggest consumers of tobacco. Women are
more likely than men to smoke 1 to 10 cigarettes per day.
.
When we look at trends over the years, we find that the predominant use
of tobacco has gradually declined since 1965.
The greatest declines have taken place primarily among young people 15
to 19 years of age. Teenagers, both
boys and girls, are now less likely to smoke than they were in the past.
.
From 1966 to 1988, the proportion of those who smoke the largest number
of cigarettes increased, but in 1989 it declined. The greatest decline is again found among young people.

INTRODUCTION
There
is much evidence to suggest that the abuse of alcohol and other drugs is
directly harmful to a large number of Canadians, and indirectly harmful to even
more. Among these drugs, tobacco is one
of the major causes of health problems in Canada.
In
earlier research efforts, such as the work done in connection with the Health
Promotion Survey of 1985, the data collected on the consumption of alcohol and
other drugs proved useful to researchers and practitioners. This showed the need for a databank that
people would be able to consult in carrying out more detailed studies of issues
relating to alcohol and drugs.
Since
1965, Health and Welfare Canada has been gathering information on the smoking
habits of Canadians, through supplements to the Labour Force Survey. The Canadian Labour Force Survey (LFS) is
the most extensive ongoing survey of households conducted by Statistics Canada.
The
development of this databank was one of the priorities of the National Drug
Strategy, which Health and Welfare Canada inaugurated on May 27, 1987 in order
to reduce the harm that drug abuse causes to individuals, families and
communities.
The
National Alcohol and Other Drug Survey is the first large Canada‑wide
study to deal specifically with the problems associated with alcohol and other
drugs. The major focus of the survey
was to study the alcohol consumption habits of Canadians. A second aim was to examine the use of
presription or over‑the‑counter drugs, of tobacco and of illegal
drugs like marijuana.
In
the National Alcoohol and Other Drugs Survey, Canadians were contacted by
telephone and asked whether they smoked cigarettes, at what age they began
smoking, if they had smoked in the past but quit, and how many cigarettes they
smoked a day.
In
this report, the main purpose of our analysis is to determine the national and
regional characteristics of smokers, and trends smoking status from 1965 to
1989.
SMOKING STATUS
Age and sex
In 1989, some 6.5 million Canadians, or
32 % of the population 15 years of age and over, smoked cigarettes. About 3.3 million men and 3.2 million women
(33 % and 31 % respectively) were current smokers¹ (Table 1). The percentage of current smokers gradually
declined from 19865 to 1989 (from 50 % to 32 %)(see Table 18). However, this rate is one of the highest in
the world (see Tables 23 and 24).
Table 1 and Figure 1 present more
detailed data on the distribution of the population by smoking status. Among people under 35 years of age, consumption
rates are similar for men and for women.
For those 35 and over, men's smoking rates are slightly higher, by 3 to
5 percentage points.² Consumption rates
are higher among adults in the 20‑54 age group (35% to 37 %), and are
lower among teenagers and older Canadians (23 % to 19 %).
[Figure 1 here]
Sixty‑eight per cent of Canadians
are non‑smokers. This category
includes both former smokers (26 %) and those who have never smoked (42
%). Because of historical differences
between men and women in regard to tobacco use, the proportion of former
smokers is higher among men (30 %) than among women (22 %). Among men, the proportion of former smokers
increases with age, while for women, it increases up to the 35‑44 age
group, and then gradually declines (Table 1).
The category of people who have never
smoked is important because it may reflect social pressures on people not to
start smoking. Approximately
─────────────────────────
¹ The category of "current smokers"
includes both daily and occasional smokers.
Since only 1 per cent of people were occasional smokers in 1989, we have
combined the two categories. In this
study, current smokers will be described simply as "smokers".
² Throughout the report, differences in
responses are expressed in percentages, namely in relation to total response
rather than to the number of individuals answering the question. For example, a decline from 30 to 20 per
cent is considered to be a drop of 10 percentage points (30 ‑ 20 = 10),
rather than a decline of 33 per cent (10/30 x 100 = 33). These differences have not been analyzed for
the statistical value, and in general, remarks are only made on differences of
3 to 4 per cent or more. Such
differences are likely significant in a sample of this size. (See Table C of Appendix B.)
42 % of the adult population state that
they have never smoked (about 37 % of men, compared to 48 % of
women). The percentage of adult males who
have never smoked decreases with age, and a higher percentage of women have
never smoked. Sixty‑three per
cent of women 65 years of age or older have never smoked, compared to 24 % of
men in this age group (Table 1).
Region
Smoking status varies from region to
region, although these differences are becoming smaller. In 1989, Newfoundland and Quebec had the
largest proportions of smokers in Canada (36 % and 35 % respectively), while
British Columbia had the smallest (28 %)(see Table 2 and Figure 2).
[Figure 2 here]
If we compare the smoking status of men
in the different provinces, we find that consumption rates are highest in
Prince Edward Island, Newfoundland and New Brunswick (38 % to 40 %). Rates observed in Manitoba and British
Columbia are lower (27 % and 29 % respectively).
Quebec and Newfoundland have the highest
proportion of women who smoke (34 %), while New Brunswick has the smallest
percentage of women smokers (23 %). In
all provinces except British Columbia, tobacco use is more widespread among
men. In British Columbia, the
proportion of women smokers is 2 percentage points higher than that of men,
while in the other provinces, the consumption rate for men is 1 to 7 points
higher than for women. The ratio of men
to women who smoke varies from 1.0 to 1.7.
Prince Edward Island and New Brunswick have the greatest differences in
tobacco use by sex. In New Brunswick,
the rate of consumption for men is 17 percentage points higher than the rate
for women, and in Prince Edward Island, the difference is 10 percentage
points. In these two provinces, the
ratio of male to female smokers is 1.7 and 1.3 respectively.
Education
The relationship between education and
tobacco use is important because it facilitates identification of target groups
for public education initiatives. Most
previous surveys showed an inverse relationship between number of years of
formal education and tobacco use, and this survey is no exception.
Consumption of tobacco is closely linked
to level of education. Table 3 and
Figure 3 present comparative data on cigarette consumption by level of
education. The ratio of smokers with a
high school diploma to university graduates who smoke is 1.8. The difference for women is 17 percentage
points, and is 14 points for men. The
percentage of smokers decreases as the level of formal education
increases. It should be noted that
these comparisons are not age‑adjusted.
[Figure 3 here]
Occupation
It is important to know the extent of
tobacco use in various occupational categories, both for epidemiological
reasons and to facilitate the development of health promotion programs. Tobacco use associated with other hazardous
substances in the workplace may have a synergistic effect more pathogenic than
the combined effect of the two particular types of exposure [U.S. Department
of Health and Human Services, 1984].
The quantities of tar, nicotine and carbon monoxide that cigarettes emit
into the ambient air are much higher than they are in the smoke inhaled by
smokers [Rickert et al., 1984].
Consequently, workers who do not smoke but who are involuntarily
exposed to cigarette smoke may run some of the same health risks as smokers
[Dosman, 1985 and Wigle et al, 1987].
In other words, they can develop the same kinds of diseases as
smokers. A recent Canadian study of
data on the composition of tobacco smoke and on health risks associated with
passive smoking suggests that there is no safe level of exposure [Collishaw et
al, 1984].
As Table 4 shows, the highest rates of
tobacco use have been found among people looking for work (42 %). blue collar
workers (41 %) and white collar workers (37 %). Those groups that had the lowest rates include students (23 %)
and retired people (24 %). Managers and
people at home fall between these two extremes, with rates of 29 % and 30 %
respectively. When tobacco use is
compared according to the sex of the respondents, we find that men are
generally more inclined to smoke than women unless they are students, blue
collar workers or managers, all groups where the proportion of smokers is
higher among women than among men. If
we look at the data in terms of employment sectors (Table 5 and Figure 4), we
find the highest proportion of smokers in the transportation sector (44 %),
followed by manufacturing (41 %) and the sales and service sector (37 %).
[Figure 4 here]
Income
Table 6 shows the distribution of smokers
by household income. Tobacco use is
closely tied to personal income and tends to decrease as income increases. For example, it is 36 % among those earning
less than $ 10,000 per year, but only 25 % for people making $ 60,000 or
more. Tobacco consumption rates for men
and for women differ greatly among those earning less than $ 10,000, but
similar for people who earn $ 10,000 or more.
Language spoken
Smoking status varies according to the
language spoken by individuals. Table 7
shows that the proportion of smokers is greater among Francophones (35 %) than
among Anglophones (31 %), for all age groups and for both sexes. The lowest percentage of smokers (27 %) is
found among people whose first language is neither English nor French. Furthermore, 81 % of women in this category
say that they have never smoked.
Ethnic origin¹
Table 8 contains data on tobacco use by
ethnic origin. It shows that the largest
proportion of smokers, namely 37 %, is found among individuals whose origin is
both Canadian and French. Moreover,
those who are Canadians only or French only have the second highest
percentage, namely 35 % in both cases.
Rates of tobacco use are lower among other Europeans (29 %) and
among people of other origins (26 %).
The greatest difference between the sexes in regard to smoking is found
among people of both Canadian and French origin, the discrepancy being 6
percentage points (40 % among men compared to 34 % for women), and among
people of other ethnic origins (where the difference is 9 percentage points).
Religion
Tobacco use is closely associated with
the religion of individuals (Table 9).
People who say they have no religion, Roman Catholics and members of the
United Church are the heaviest smokers, each group having a consumption rate of
about 34 %. Next in order come the
Anglicans (31 %) and other Protestants (29 %).
The lowest proportion of smokers (24 %) is found among people who belong
to other religions. This category also
contains the largest percentage of people who have never smoked, namely more
than half.
─────────────────────────

See note on Table 8 for a definition of "ethnic origin".
DAILY
CIGARETTE CONSUMPTION
Mortality risks vary according to smoking
status and degree of exposure to risk factors.
People who currently smoke cigarettes are much more likely to suffer
diseases associated with tobacco use and to die of them than former smokers or
people who have never smoked. It has
been established that tobacco‑related risk depends upon the number of
cigarettes smoked per day, the tar and nicotine content of the cigarettes
smoked, the habit of inhaling smoke, and the duration of tobacco use. This report contains information on the
frequency of tobacco use.
Data on the distribution of smokers by
number of cigarettes smoked per day in 1989 (Table 10) indicate that 26 % of
Canadian smokers consumed 1 to 10 cigarettes per day, 64 % smoked 11 to 25
cigarettes and 10% had more than 25 cigarettes per day. Some Canadian manufacturers have recently
marketed packs of 30 cigarettes. If
this trend catches on, the proportion of smokers consuming more than 25
cigarettes per day could further increase.
Age and sex
Table 10 shows that in general, men are
heavier smokers. About 13 % of
male smokers consume more than 25 cigarettes per day, compared to 6 per cent of
women smokers. The proportion of
smokers consuming more than 25 cigarettes per day increases with age for both
men and women, up to the 45‑54 age group. The highest percentage of smokers consuming less than 10
cigarettes per day, namely about half (50 %), is found in the 15‑19
age group. They are followed by the
group of people 65 years of age and over, where the corresponding figure is
nearly 34 % (Table 10).
Region
The proportion of individuals who
regularly smoke more than 25 cigarettes per day varies by region. Table 11 shows that the highest proportion
of such smokers is in Quebec (14 %), followed by British Columbia (12 %). The Atlantic provinces are close to the
national average, with 10 %, and the lowest percentages are in Ontario (8 %)
and in the Prairie provinces (5 %). In
all regions, women generally smoke fewer cigarettes than men.
Education
Table 12 indicates that more smokers with
between zero and eight years of formal education smoke more than 25 cigarettes
per day. The consumption habits of men
were largely responsible for this particular configuration of data in the
overall population. Approximately 15 %
of men with less than eight years of schooling consumed more than 25 cigarettes
per day. Men smoke more than women in
general, but for both sexes, the proportion of smokers consuming less than 10
cigarettes per day becomes progressively larger as the level of education
rises. In the group of women with the
most education, for example, 43 % of smokers consumed fewer than 10 cigarettes
per day. These results are similar to
those of Table 3, which shows that tobacco use decreases as the level of
education increases.
Occupation
Table 13 indicates that among smokers,
students have the lowest rate of daily cigarette consumption. Half of student smokers consume between one
and 10 cigarettes per day. This rate is
more than 21 percentage points above the rates for the groups of managers and
of retired people, which follow with 30 % each. Blue collar workers seem to be the heaviest smokers, 12 % of them
smoking more than 25 cigarettes per day.
The largest percentages of average smokers (consuming between 11 and 25
cigarettes per day) are found among white collar workers (70 %), blue collar
workers (69 %) and people at home (68 %).
Similar results are recorded in Table 4 in regard to frequency of
tobacco use.
Income
Table 14 gives the distribution of
smokers by income. Tobacco use is
highest among people who earn between $ 30,000 and $ 59,999 (11 % smoke more
than 25 cigarettes per day). Those who
have an income of less than $ 10,000 have the highest percentage of smokers
consuming less than 10 cigarettes per day (31%). They are followed by those who earn between $ 10,000 and $
29,900 and by people earning more than $ 60,000, both of these groups having a
proportion 0f 27 %.
Language spoken
Table 15, which gives the distribution of
smokers by number of cigarettes smoked per day and by language spoken, shows
that as a group, people who speak neither French nor English have the highest
percentage of smokers consuming less than 10 cigarettes per day (38 %). Francophones are more inclined than
Anglophones to smoke more than 25 cigarettes per day, the percentages for these
groups being 13 % and 8 % respectively.
Similar results are recorded in Table 7 in regard to frequency of tobacco
use.
Ethnic origin
Tobacco use varies according to ethnic
origin, as Table 16 shows. People who
have identified themselves as being of Canadian and French origin seem to have
the largest proportion of smokers consuming more than 25 cigarettes per day
(15 %). On the other hand, the highest
percentage of smokers who have less than 10 cigarettes per day (34 %) is found
among people whose origin is other than Canadian, French, English or
European. This model agrees with the
distribution of types of smokers (Table 8).
Religion
We have seen above that religion has an
influence on the consumption of tobacco (Table 9). Table 17 shows the effect of religion on the number of cigarettes smoked per day. People who do not adhere to any specific
religion have the highest percentage of smokers of 25 more more cigarettes per
day (13 %). This percentage is 10 % or
less for each of the other categories of religion. Members of the United Church and Anglicans are more inclined than
other groups to smoke between 11 and 25 cigarettes per day (69 % and 68 %
respectively), while people whose religion is other than those mentioned in the
table show the lowest daily consumption, with 34 % who smoke between one
and 10 cigarettes per day.
CHANGES IN SMOKING BEHAVIOUR
Proportion of smokers
Changes have occurred in the consumption
of cigarettes since 1965. Figure 5
shows that the percentage of smokers has steadily declined over the last 25
years, from 50 % in 1965 to 32 % in 1989 (see Table 18).
[Figure 5 here]
Among young people, smoking has dropped
off considerably since 1979. Figure 6
shows that the percentage of young smokers (15 to 19 years of age) has
decreased more than the percentage of smokers aged 20 to 24. It is too early to determine whether there
is a long‑term levelling off among young people (see Table 19).
[Figure 6 here]
In general, this decline has been much
more pronounced among men than among women, the figures for the two sexes being
21 and 3 percentage points respectively.
It should, however, be noted that in 1966, the proportion of regular
smokers among men was much higher than among women, the difference being 22
percentage points (54 % for men compared to 32 % for women). Today, however, the percentages for the two
sexes are much closer together than they were in 1966. In 1989, indeed, the proportion of regular
smokers was 33 % for men and 31 % for women (Table 1). Furthermore, while there are more men than
women 25 years of age and over who smoke every day, men and women have similar
rates in the under‑25 age group.
Another point that should be stressed is that while among men, the
percentages of regular smokers are lower than they were in 1989 for every age
group, some age groups of women show an incrase in regular smokers in
comparison with 1966. For example,
among women 65 years of age and over, the proportion of regular smokers has
risen from 8 % in 1966 to 16 % in 1989.
This change is primarily attributed to aging of the smokers' group, and
to replacement of the oldest cohort of non‑smokers as the years went
by. This development, then, is probably
a temporary phenomenon.
Daily consumption
Smokers are today thought to be more
aware than they were in the past of dangers caused by cigarette smoking. Canadians have seen steep tax increases on
tobacco products, and now face greater restrictions of smoking in public and in
the workplace. Smokers have responded
to these pressures by reducing their daily consumption of cigarettes. Although the percentage of smokers has not
changed much since 1986, Table 20 shows that changes have occurred in the daily
consumption of smokers, namely in the number of people who smoke every
day. We find in fact that between 1986
and 1989, the proportion of people who smoke 26 or more cigarettes per day has
declined by 3 per cent. We also find a
drop of 4 per cent in the proportion of average smokers, namely those who smoke
between 11 and 25 cigarettes per day.
The result of these changes is an increase of 6 per cent in the number
of people who smoke few cigarettes (1 to 10 per day).
The percentage of smokers consuming 26 or
more cigarettes per day grew somewhat from 1966 to 1981 (from 8 to 13 %), and
has since been on the decrease. The
proportion of smokers in this category has decreased for both men and women, by
2 and 3 percentage points respectively (Table 20).
The proportion of people who smoke less
than 10 cigarettes per day has grown since 1981. The largest increase in this category, from 38 % to 51 %,
occurred in the 15‑19 age group.
This great change is largely attributable to women, who recorded a 24
percentage point increase during this period (Table 20).
ALCOHOL AND TOBACCO CONSUMPTION
In Canada, cigarette smokers have a
greater tendency to consume alcohol than those who have never smoked (see
Figure 7). They are also more likely to
take more drinks per week (see Figure 8), and to have consumed five or more
drinks at least 15 times during the previous year (see Figure 9). Eighty‑three per cent of regular and
former smokers drink at least "occasionally", compared to 70 % of
those who have never smoked (see Table 30).
On the average, regular smokers have 5.2 drinks per week, compared to
former smokers (3.9) and those who have never smoked (2.4).
The proportion of heavy drinkers (namely
those who have had 5 or more drinks at least 15 times during the previous year)
is twice as high among regular smokers (18 %) and it is among former smokers (9
%) or those who have never smoked (7 %)(see Table 31).
INTERNATIONAL COMPARISONS
Sales trends
Table 23 gives tobacco sales figures for
some industrialized and developing countries.
Although short‑term trends may show
fluctuations, some long‑term trends do emerge. For most countries, the record year came in the early 1980s,
while in some European countries, tobacco sales were declining since the
1970s. There were only six countries in
which sales were at their highest level in 1983, the last year for which
figures were available.
Sales figures are expressed in millions
of product units manfactured. Tobacco
sales are governed by number of factors:
taxes above all of course, the economic situation, advertising and the
existence or lack of programs and restrictions to reduce tobacco use. Periodic tax increases generally result in a
substantial drop in sales.
Studies of smoking behaviour
Studies of smoking behaviour are a useful
source of information, because they enable us to draw a profile of smokers and
their behaviour. These studies provide
valuable information on public health, making it possible, for example, to
identify populations at risk. Table 24
gives an overview of smoking rates among adults 15 years of age and over, based
on reliable probability surveys conducted around the world.
The definitions of "smokers",
"non‑smokers" and "former smokers" may differ
slightly. They are, however, generally
based on self‑declared information.
We encourage the reader to exercise caution before drawing conclusions
about the classification of countries on the basis of data contained in this
work [WHO, 1986]. However, the figures
do show that on a worldwide basis, men were more likely to be smokers than
women, at least in the early 1980s, and that smoking rates in Canada for both
sexes were similar to those of other developed countries.
CONCLUSION
Since 1966, tobacco consumption seems to
have gradually decreased, and the proportion of Canadians who smoke has
declined considerably. Moreover,
tobacco consumption habits are changing among those who still smoke, and regular
smokers were smoking much less in 1989 than they had in previous years.
It is interesting to note that the
changes that have occurred show a convergence in the smoking behaviour of men
and women. This increasing similarity
in the smoking habits of both sexes is due to the fact that men have reduced
their smoking more than women. It is
also important to note that differences in tobacco use rates continue to be
recorded in different regions and socioeconomic groups.
In general, tobacco use is one of the
major causes of health problems in Canada.
More than 38,000 Canadians die each year of diseases associated with the
consumption of tobacco [Collishaw and Leahy, 1991]. An evaluation of prevention and treatment studies indicates that
reduction in tobacco use and in its attendent problems is possible when all the
parties concerned work together to encourage optimal use of resources and to
create a climate conducive to making changes in standards and behaviour.
