Smoke or Chew? Comparing the Health Risks of Different Tobacco Products

When it comes to tobacco use, the options are often diverse, ranging from smoking to chewing. The question often arises: which form of tobacco is more harmful to one's health? Let's delve into a comparative analysis between smoking and chewing tobacco to uncover the potential health risks associated with each method.

The Chemistry Behind Chewing Tobacco

Chewing tobacco is a product that contains tobacco leaves mixed with a small amount of slaked lime to dissolve nicotine off the leaf. This mixture is further enhanced with flavouring agents, often used in smaller quantities to make the taste more palatable. Additionally, tobacco extract is often added due to its insecticidal properties. Alkaloids present in these extracts contribute to the insecticidal effect.

Average users may consume about 10 times a day, with each use lasting approximately 6 minutes. This results in a brief daily exposure of about an hour, but the harmful chemicals have a prolonged effect on the oral mucosa. The strong alkali in the mixture not only dissolves nicotine but also erodes the inner lining of the mouth, allowing for the absorption of these chemicals into the body.

Smoking: A Closer Look at Cigarettes

When it comes to smoking, consider the following: an average smoker might light up 10 cigarettes a day, with each cigarette lasting between 5 and 6 minutes. While a gram of tobacco is burned, only a portion of it—about 60-70%—is inhaled into the lungs. The remaining ash is left behind in the cigarette's filter. Out of the inhaled smoke, the non-gaseous components, or tars, account for roughly 3%. Interestingly, some of this tar contains less than 1% that isn't harmful, but the rest is a complex cocktail of Aromatic hydrocarbons, many of which are carcinogenic.

The significant issue with smoking lies in how the tar is deposited and where it goes. It is widely distributed across a large surface area, potentially equivalent to that of a tennis court. The contact with this tar lasts for mere seconds, after which it is exhaled. However, a small portion of this tar is absorbed at the site of deposition, and the rest is carried by the mucocilliary escalator to the food pipe, eventually reaching the gastrointestinal system.

Comparative Analysis: Smokers vs. Chewers

Smokers: While the amount of poison ingested might be microscopic, it is highly toxic. The tar deposited from smoking is a complex mixture of harmful substances. Approximately 1% of this tar is deposited in the body, and the rest is exhaled, but this small amount can be highly detrimental.

Chewers: The higher quantity of poison ingested by chewers is somewhat more in quantity. However, the presence of a strong alkali in the mixture can be considered a potential saving grace, as it both aids in the release of nicotine and erodes the inner lining of the mouth, potentially reducing the absorption of harmful chemicals.

Conclusion: The Dangers of All Forms of Tobacco Use

Regardless of the form—snuffing, chewing, smoking, or using quid, the use of tobacco presents significant health risks. Both methods expose the body to harmful chemicals, including carcinogenic compounds. Therefore, it is crucial to consider quitting all forms of tobacco use as a step towards better health and well-being.
