Is Passive Smoking More Harmful Than Active Smoking?
Most of us know that smoking is injurious to
health but do we know that smoking can be classified into two which are active
smoking and passive smoking. Are we aware about the fact that passive smoking
is equally or even more harmful than active smoking?
In general, smoking is defined as a practice
where substance such as dried leaves of tobacco plant are rolled into a
cylinder called “cigarette” is burned and the resulting smoke is absorbed into
the bloodstream. Active smoking is basically smoking by using cigarettes and
the combustion that occurs in the cigarette is released out as smoke. The
combustion of the active substance in the cigarette that occurs vaporizes and
delivers the substances into the lungs where they are rapidly absorbed into the
bloodstream and reach the tissues in the body. Based on Better Health Channel
(2015), passive smoking is breathing in other people’s tobacco smoke. Exhaled
smoke is called exhaled mainstream smoke. The smoke drifting from a lit
cigarette is called a sidestream smoke. The combination of mainstream and
sidestream smoke is called second-hand smoke (SHS) or environmental tobacco
smoke (ETS).
Active smoking is injurious as it affects the lungs by
causing lung infections and lung cancer. It also affects the heart, blood
vessels and blood circulation in a harmful way. Active smokers are at high risk
of getting heart diseases, stroke and heart attacks.
Besides, passive smoking also brings a lot of health risks
to public especially to children, pregnant women and unborn babies. Passive
smoking is harmful as the secondhand smoke (SHS) contains a lot of chemicals
such as irritants and toxins. Frequent exposure to SHS increases a person’s
risk of lung cancer, coronary heart diseases such as heart attack, angina
(chest pain), heart failure and stroke. Children and babies who are exposed to
SHS have higher risk of getting upper respiratory and lung infections, ear
infections, asthma attacks and sudden infant death syndrome. Parents who smoke
can cause wheezing, coughing, bronchitis and pneumonia in their children. Moreover,
pregnant women have high chances of having spontaneous abortion (miscarriage),
stillborn birth, low birth-weight baby and other pregnancy and delivery
problems when exposed to SHS.
Passive smoking causes more harmful effects than active
smoking. Based on Hindustan Times (2014), Dr. (Col) SP Rai, consultant in
pulmonary medicine, Kokilaben Dhirubhai Ambani Hospital and Medical Research
Institute, Andheri (W) says that “The fume that burns off the end of a
cigarette or cigar actually contains more harmful substances than the smoke
inhaled by the smoker, as there is no filter through which it passes. The
particles are also smaller, which allows them to stay longer in the air and go
deeper into your lungs”.
Other than that, based on The Hindu (2013), Dr. Vishal
Rao said that “Passive smoking is more dangerous than active smoking as more
than 6,000 children were getting admitted to hospitals every year in the
country for various ailments caused by passive smoking. Of late, cases of
sudden infant death syndrome have increased due to people smoking in their
houses, without bothering about the health of their children. We have come
across several cases of healthy babies going to sleep at night found dead in
the morning. Such cases are the result of people smoking continuously in the
room, which cause suffocation to the baby”.
In addition, based on Hilton P., FitPerez (2011), Second-hand
smoke (SHS) is considered more dangerous than the mainstream smoke that is
actually inhaled. The smoke that comes off the end of the cigarette has a
higher concentration of cancer-causing agents. A person who smokes actually is smoking
the cigarette though a filter which diminishes the harmful toxins. When smokers
blow out the smoke, it lingers in the air for several hours afterwards and
affects the lungs and oxygen levels of the people around the smokers. Breathing
SHS for a short time can irritate the lungs and reduce the amount of oxygen in
your blood. Prolonged or repeated exposure to SHS is much more dangerous. And
it isn’t just the smoke that’s a concern. The residue that cling to a smoker’s
hair and clothing, household cushions and carpeting continue to poses a health
threat. Estimated around 600,000 die worldwide from SHS and they weren’t even
smokers.
In a nutshell, it is clear that passive smoking is more
harmful than active smoking. Therefore, we should work hand in hand to reduce
smoking in order for the future generation to experience a smoke-free and
healthy environment. This is because children who grow up with family members
who smokes tend to start smoking themselves. If you’re a parent who smokes,
then it will be hard to explain to your children why they shouldn’t start
smoking. We should try to lead the children by quitting smoking as they may be
less likely to start smoking later in life as well as improving your health and
theirs. We can start by providing children with smoke-free environment
including home, car and public places where children spent most of their time.
