While the popular belief is that smoking largely affects the lungs because they get directly exposed to inhaled smoke, health experts warn that it also impacts the entire cardiovascular system.

According to the World Health Organisation (WHO), smoking tobacco is globally the second leading cause of heart diseases after high blood pressure. Nearly 12 per cent of cardiovascular deaths worldwide occur due to tobacco abuse and secondhand smoking.

In tobacco cigarette, there is combustion, a burning of an organic material that generates temperatures up to 900 degree Celsius. Chronic exposure to this tends to thicken blood vessels, making them weaker in the long run. This can lead to blood clots and ultimately result in stroke or peripheral heart diseases.

“Inhaling the smoke from tobacco builds fatty material — atheroma — in the heart of the smoker which then damages the inner lining of arteries and also narrows them further,” Tapan Ghose, Director & HOD, Cardiology at Fortis Flt. Lt. Rajan Dhall Hospital, told IANS.

“This narrowing can cause the angina, stroke or heart attack,” he added.

Further, the presence of nicotine in the cigarettes raises the blood pressure, which can have a detrimental effect on the heart’s oxygen balance.

“Nicotine causes thickening of the blood vessels, which hampers the blood flow and also causes high blood pressure or hypertension,” Mukesh Goel, Senior Consultant, Cardio Thoracic & Vascular Surgery at Indraprastha Apollo Hospitals, told IANS.

Tobacco also has carbon monoxide, which blends with haemoglobin in the blood more easily than oxygen does, thus affecting the oxygen supply in the body.

The carbon monoxide prevents the blood system from effectively carrying oxygen around the body, specifically to vital organs such as the heart and brain, the experts said, adding that apart from regular smokers, those who inhale the smoke passively may also be at risk.

WHO states that of the seven million lives that tobacco claims worldwide each year, almost 900,000 are passive-smokers.

Tobacco, whether smoked, swallowed, or chewed poses multiple hazards. In addition to affecting the lungs and heart, it also increases the risk of head and neck, lung, esophageal, pancreatic, and urologic cancers.

According to a recent study published in The Journal of Physiology, smoking could directly damage the muscles by reducing the number of blood vessels in leg muscles, which in turn reduce the amount of oxygen and nutrients the muscles receive.

This may impact the metabolism and activity levels.

Moreover, smoking also affects both male and female fertility, doctors said.

“Women smoking tobacco reduce their chances of conceiving by at least 60 per cent and is also linked to ectopic pregnancy and other tubal factor infertility,” Sagarika Aggarwal, an IVF expert at Indira IVF Hospital, New Delhi, told IANS.

On the other hand, male smokers can suffer from decreased sperm quality with lower mobility and increased numbers of abnormally-shaped sperms.

Moreover, chain smoking might also decrease the sperm’s ability to fertilise eggs.

Besides causing infertility, tobacco during pregnancy can also lead to multiple issues ranging from miscarriage to under-development of the foetus and making the child susceptible to various forms of disorder such as Attention Deficit Hyperactivity Disorder (ADHD), Goel noted.

Quitting is the best way, the experts said while discouraging the use of alternatives like e-cigarettes.

“While it is true that e-cigarettes have less quantity of tobacco as compared to regular cigarettes, bidis or hookah, but they also expose lungs, heart and other organs to very high levels of toxic substances,” Goel said.

Other measures like clinical interventions, counselling and behavioural therapies can help people quit tobacco abuse.

“Nicotine replacement therapy, including nicotine patches, gum, lozenges, inhalers etc, has been found to be effective. Combination therapy with drugs like bupropion has been found to be more effective than nicotine replacement alone,” said Viveka Kumar, Senior Director, Max Heart & Vascular Institute, Saket.

Kumar also emphasised on the role of mass media in spreading awareness about the harmful effects of tobacco, while curbing the easy access to tobacco, especially among the younger vulnerable population.

“Availability and accessibility of smoking cessation programmes to smokers who want to stop smoking remains an area which needs to be addressed,” Kumar said. (IANS)

WHO vows tighter, broader action against tobacco, industry interference.

The World Health Organization (WHO) unveiled a global strategy on Saturday to scale up the tobacco control agenda over the next few years and to prevent further interference by tobacco industry in public health policies.

The strategy, titled the Medium-Term Strategic Framework (MTSF), aims to strengthen implementation of the WHO Framework Convention for Tobacco Control (FCTC), with a roadmap to guide the work of the convention parties, the secretariat and other stakeholders with regards to tobacco control from 2019 to 2025, Xinhua reported.

“The adoption of this strategy marks a key milestone in strengthening the FCTC,” said Vera Luiza da Costa e Silva, head of the WHO FCTC Secretariat. “This strategy provides a very clear path forward, with priorities and objectives to reinforce government policies and accelerate global action for more effective implementation of the tobacco control treaty.”

The strategy was concluded during the eighth session (COP8) of the FCTC, which brought together over 1,200 participants, including delegations from 148 parties to the global tobacco control treaty and representatives of UN agencies, other intergovernmental organisations and civil society.

They also agreed to maximize transparency to protect FCTC related sessions and proceedings from the intrusion of tobacco industry representatives and interests.

“More than ever, we need to stay the course and strengthen our commitment to ensure that FCTC efforts to protect and promote public health and sustainable development are not hijacked by the tobacco industry,” Costa e Silva said. “We must yield no ground to the tobacco industry.”

To prevent further interference by tobacco industry in public health policies, the strategy requires parties to the treaty to protect national public health policies “from commercial and other vested interests of the tobacco industry.”

In addition to tighter control actions, the parties also addressed the need for tobacco control efforts to integrate strategies to combat the destructive impacts of tobacco on the environment and sustainable development.

Since it came into force in 2005, the FCTC has resulted in national strategies and legislation that have introduced health warning on packages of tobacco and comprehensive bans on tobacco advertising, promotion and sponsorship.

As the only existing global intergovernmental meeting exclusively devoted to tobacco control, the FCTC COP has served as a platform for policy formulation and the adoption of implementation mechanisms by the parties to the convention. (IANS)
