The
Desire to Stop Smoking
The desire to stop smoking
Many
smokers continue smoking not through free choice but because they
are addicted to the nicotine in cigarettes. A report by the Royal
College of Physicians found that nicotine complied with the established
criteria for defining an addictive substance. The report states:
"On present evidence, it is reasonable to conclude that nicotine
delivered through tobacco smoke should be regarded as an addictive
drug, and tobacco use as the means of nicotine self-administration."
[1]
Surveys have consistently shown that at least
70% of adult smokers would like to stop smoking.[2]
A 1999 survey found that, of those who expressed a desire to quit,
a third were very keen to stop.2 The same survey found that the
more a person smokes the less faith that person has that he or she
can stop. The most important element of the cessation process is
the smoker's decision to quit, with the aid or method of secondary
importance. However, those who use aids such as nicotine replacement
therapy double their chances of successfully quitting.[3] Smokers
wishing to quit may find it helpful to telephone the national helpline
on 0800 169 0169. Pregnant women seeking help in stopping smoking
should call 0800 169 9169 where specialist counsellors are available
from 1pm to 9pm, 7 days a week, to give advice. QUIT also operates
specialist advice lines in the main Asian languages and in Turkish
and Kurdish.

Beneficial health changes
when you stop smoking
Stop
smoking and the body will begin to repair the damage done almost
immediately, kick-starting a series of beneficial health changes
that continue for years.[4]

Risk of heart attack falls to the same as someone
who has never smoked. |
Withdrawal symptoms
Withdrawal
symptoms are the physical and mental changes that occur following
interruption or termination of drug use. They are normally temporary
and are a product of the physical or psychological adaptation to
long-term drug use, requiring a period of re-adjustment when the
drug is no longer ingested. In the case of smoking, some of these
are: [5]

Weight gain
The
possibility of weight gain is often of particular concern to those
who want to give up smoking. More than 80% of smokers will gain
weight once they quit smoking, but the long-term weight gain is
on average only 6-8lbs for each smoker who quits.[6] However, this
is the weight gain made without recourse to any special attempts
at dieting or exercise and it presents a minor health risk when
compared to the risk of continued smoking. In addition, improved
lung function and some of the other health benefits of giving up
smoking are likely to make exercise both easier and more beneficial.
Pipes & cigars
Some
smokers switch to pipes or cigars in the belief that this is a less
dangerous form of smoking. However, such smokers may incur the same
risks and may even increase them, especially if they inhale the
pipe or cigar smoke.[7]
Smoking cessation aids
There
are two proven pharmaceutical aids to stopping smoking: nicotine
replacement therapy and bupropion, known by its tradename, Zyban.
Nicotine replacement therapies (NRT), such as chewing gum, skin
patch, tablet, nasal spray or inhaler, are designed to help the
smoker to break the habit while providing a reduced dose of nicotine
to overcome withdrawal symptoms such as craving and mood changes.
Studies have shown that NRT roughly doubles the chances of a smoker
successfully quitting compared to someone using no therapy.[8]
Bupropion, (Zyban)
works by de-sensitising the brain's nicotine receptors and has shown
promising results in clinical trials. The course of treatment lasts
around 8 weeks. It is only available on prescription under medical
supervision. Zyban is safe for most healthy adults but there are
side effects, the most serious of which is the risk of seizures
(fits). This risk is estimated to be less than 1 in 1000 but other
less serious side effects such as insomnia, dry mouth and headaches
are more common. An independent review by the Consumers' Association
concluded that "when used in a specialist setting and in conjunction
with regular counselling, bupropion is at least twice as effective
as placebo in helping patients to stop smoking".[9]
.
Other cessation aids
Acupuncture
and hypnosis. A review of alternative methods of aids to stopping
smoking found little evidence to support the effectiveness of either
acupuncture or hypnosis as a means of stopping smoking, but such
methods may suit some smokers.[10]
Top of Page
Herbal cigarettes. These
are not recommended as an aid to giving up smoking because they
produce both tar and carbon monoxide. Some brands have a tar content
equivalent to tobacco cigarettes. In addition, the use of herbal
cigarettes reinforces the habit of smoking which smokers need to
overcome.
Clinics and self-help groups.
Smokers
who are motivated to quit the habit may benefit from cessation clinics
or self-help groups, although smokers should be cautious about claims
of high success rates made by some clinics. A review of smoking
cessation products and services found that smokers are up to four
times more likely to stop smoking by attending specialist smokers'
clinics than by using willpower alone.[11] As part of the Government's
review of the NHS, more smoking cessation clinics are being established
by health authorities and primary care groups.[12]
