Enter any hookah bar or browse through online discussions about vaping, and you will quickly notice a common belief: some forms of smoking are considered safer than others.
Many people assume that light cigarettes contain fewer harmful chemicals, that vaping is a healthier alternative to smoking, or that the water in a hookah filters out dangerous toxins. However, according to lung health experts, these assumptions can be misleading.
According to Dr Mansi Vadgama, Consultant, Pulmonology, Paras Health Udaipur, there is growing concern about the popularity of alternative smoking products, particularly among younger users who often perceive them as lower-risk options.
The "light" cigarette myth
The idea of the light cigarette has been around for decades, with cigarette brands marketing certain products as "light" or "mild".
In reality, the difference is far smaller than many smokers realise.
According to Dr Vadgama, so-called light cigarettes were designed with tiny ventilation holes in their filters to dilute smoke with air. However, smokers often compensate unconsciously by inhaling more deeply, taking longer drags or smoking more frequently to achieve the same nicotine effect.
As a result, the body can end up absorbing a similar amount of harmful chemicals despite the "lighter" label.
Some studies have even linked these deeper inhalations to a higher risk of certain types of lung cancer that develop deeper within the lungs.
Why vaping isn't as harmless as it looks
E-cigarettes are often marketed as modern alternatives to traditional cigarettes. Their sleek designs and flavoured options have helped make them popular around the world.
However, health experts warn that the vapour inhaled through e-cigarettes is not simply harmless water vapour.
According to Dr Vadgama, e-cigarette aerosols can contain substances such as formaldehyde, nickel and lead. Studies have linked vaping to a range of health risks, including lung injury and cardiovascular disease.
In India, where e-cigarettes are banned under the Prohibition of Electronic Cigarettes Act, concerns remain about illegal products entering the market without proper quality control or safety oversight.
The hookah misconception
Perhaps no smoking habit carries a healthier image than hookah.
Many users believe the water inside a hookah acts as a filter, removing dangerous substances before the smoke reaches the lungs. Unfortunately, specialists say this belief is scientifically inaccurate.
According to the expert, a single one-hour hookah session may expose a person to as much smoke as dozens of cigarettes.
Hookah smoke also contains carbon monoxide, heavy metals and other harmful substances that can damage both the lungs and cardiovascular system over time.
The rise of social smoking
One reason hookah remains popular is that it is often viewed as a social activity rather than a smoking habit.
Friends gather around a single pipe, share flavours and spend hours talking, which can make the health risks feel less obvious.
However, pulmonologists are increasingly concerned that social smoking may normalise tobacco use among younger adults who would not otherwise consider themselves smokers.
When combined with factors such as urban air pollution and other environmental exposures, the long-term impact on lung health can be significant.
Whether nicotine is delivered through a cigarette, vape, hookah or another smoking device, experts say the core health risks remain.
Dr Vadgama emphasises that there is currently no evidence to suggest that exposure to tobacco or nicotine products is completely safe. While the packaging, technology and marketing may differ, the lungs are still exposed to substances that can cause harm.
For people looking to protect their health, the goal should not be finding a "safer" way to smoke, but reducing dependence on nicotine altogether.
