DEPENDENCE



According to World Health Organisation estimates, there are
currently 4 million deaths a year from tobacco - a figure
expected to rise to about 10 million by the 2020s or early
2030s. By that date, based on current smoking trends,
tobacco is predicted to be the leading cause of disease
burden in the world, causing about one in eight deaths.

Tobacco and health is the focus of this week's theme issue of
the BMJ ± from children's exposure to passive smoking to
disturbing truths about tobacco industry practices - this issue
marks next week's world conference on tobacco or health.

Three papers in this week's BMJ support a comprehensive
approach to protect children from environmental tobacco
smoke and prevent them from becoming established
smokers.

Jarvis and colleagues find that exposure to passive smoking
among 11-15 year old children in England has almost halved
since the late 1980s, partly due to a fall in the percentage of
parents who smoke, and also to reduced smoking in public
places. Similarly, Wakefield and colleagues report that bans
on smoking at home - as well as bans in public places and
enforced school smoking bans - may reduce teenage smoking
in the United States. They suggest that one explanation for
this may be that exposure to environmental tobacco smoke
during childhood may make children more inclined to take up
active smoking in their teenage years "by reducing the
noxious deterrence of the first cigarette."

Finally, Hovell and colleagues find that behavioural
counselling for mothers in California was effective in reducing
young children's exposure to tobacco smoke at home -
illustrating the potential of techniques that impact directly on
smoking parents. This view is reiterated in an accompanying
editorial by Ferrence and Ashley, who suggest that shifting
public attitudes towards smoking at home in the presence of
children means that the climate is now right for behavioural
interventions aimed at parents. It is clear, however, that no
one strategy will work alone, they say. In addition to
increasing smoking restrictions in public places and
workplaces, price increases, reduced availability of tobacco
products, and mass media interventions, are also crucial if we
are to protect children's health and prevent their recruitment
to smoking in adolescence.

(2) PREVIOUSLY SECRET DOCUMENTS REVEAL THE
TRUTH ABOUT THE TOBACCO INDUSTRY

Previously secret internal tobacco industry documents - now
publicly available - form the basis for three studies in this
week's BMJ. They provide a unique insight into an industry
determined to protect its commercial interests at the expense
of world-wide public health.

Francey and Chapman reveal that in 1977, seven of the
world's major tobacco companies formally conspired to
promote "controversy" over smoking and disease and to
mount a program of "smoker reassurance" to counter the
increasing social unacceptability of smoking. This conspiracy,
say the authors, led to the formation of the International
Committee on Smoking Issues, later to become the
International Tobacco Information Centre, which operated
through "task forces" to undermine tobacco control measures
throughout the world.

Co-operation between the manufacturers of tobacco and
candy cigarettes to effectively promote smoking in children is
described by Klein and St Clair. They show that some
tobacco companies granted confectioners permission to use
cigarette pack designs, tolerated trademark infringement and
suppressed research showing the potentially harmful effects of
candy cigarettes in promoting smoking to children.

Hastings & MacFadyen show that UK tobacco companies
are actively seeking to encourage smoking - not just extend
brand share as they frequently claim. They attract and retain
"new entrants" to the market by creating "aspirational, lifestyle
brand" images to enhance the appeal of what they recognise
as a "rites of passage" behaviour. Everything from pack
design to clever sponsorship deals are used to strengthen
these brands and "engage" youngsters' "aspirations and
fantasies" say the authors. The naked commercial imperative
that underpins this activity totally discredits voluntary
regulation and demonstrates that tightly policed, statutory
controls are essential.

These documents contain information that shocks even
hardened anti-tobacco activists, says Stanton Glantz in an
accompanying editorial. He suggests that it is time for British
American Tobacco to make its documentation freely
available on the internet - as American tobacco companies
agreed to do as part of a settlement of lawsuits in 1998. "It
will force the truth out of the shadows and into the public
eye" he concludes.

(3) IMPROVING THE TREATMENT OF TOBACCO
DEPENDENCE

case-control studies)

Three articles in this week's BMJ demonstrate the
importance of stopping smoking or discuss the effective
methods currently available to help people kick the habit.

The health benefits of stopping smoking are highlighted in a
paper by Peto and colleagues. They show that people who
stop smoking ± even at 50 or 60 years of age ± avoid most of
their risk of developing lung cancer, and quitting before
middle age avoids more than 90% of the risk caused by
tobacco.

Speaking at the press conference will be Professor Sir
Richard Peto, Professor of Medical Statistics and Professor
Sir Richard Doll, Emeritus Professor of Medicine - author of
the 1950 landmark study linking smoking with increased risk
of lung cancer and co-author of this new study, fifty years on.

Many people who smoke make multiple attempts to quit, and
will benefit from the availability of a range of aids to help
them, according to a paper by Lancaster and colleagues.
They find that advice from health professionals, individual and
group counselling, nicotine replacement therapy and certain
antidepressants are among the most effective interventions
currently available to help people stop smoking. For smokers
who are either unable or unwilling to stop abruptly, Bolliger
and colleagues show that using a nicotine inhaler can reduce
cigarette consumption by over 50% over a two-year period.
Although the overall success rates were relatively small, say
the authors, this is a feasible first step towards improved
health, and may ultimately lead to these smokers quitting
altogether.

These findings emphasise the simple, yet powerful messages
that clinicians can and should communicate to all patients,
suggest Thun and Glynn in an accompanying editorial.
?Firstly, don?t smoke. Secondly, if you do smoke, there are
major health benefits to stopping as soon as possible, no
matter what your age or how long you have been smoking.
Thirdly, there are a wide array of effective cessation
treatments now available.?
