2. Heat-Not-Burn Products
These devices heat tobacco rather than burning it, producing an aerosol that contains nicotine and flavors without combustion. They aim to provide a smoking-like experience with reduced exposure to harmful chemicals found in cigarette smoke.

Mechanism: Heat-not-burn devices typically heat tobacco sticks (IQOS) or pods (Ploom) to a lower temperature than combustion, releasing nicotine and flavors without generating smoke.

Regulation: Their regulation varies globally, with some countries treating them differently from traditional tobacco products.

3. Nicotine Replacement Therapy (NRT)
NRT products are designed to help smokers quit by providing controlled doses of nicotine without the harmful substances found in tobacco smoke. They include nicotine gums, patches, lozenges, inhalers, and nasal sprays.

Purpose: NRT products reduce withdrawal symptoms and cravings, supporting smokers during the quitting process.

Effectiveness: When used as directed, NRT products are effective in helping smokers quit or reduce their cigarette consumption.

Snus is a smokeless tobacco product originating from Sweden. It consists of moist tobacco powder placed under the upper lip, where nicotine is absorbed through the oral mucosa.

Usage: Unlike chewing tobacco, snus does not require spitting and is discreet to use.

Safety: It is associated with lower risks of oral cancer and respiratory diseases compared to smoking.

Benefits and Considerations
Health Benefits: Smoke-free alternatives reduce exposure to harmful chemicals and carcinogens found in cigarette smoke, lowering the risk of smoking-related diseases.

Reduced Environmental Impact: They produce less environmental pollution compared to traditional cigarettes.

Regulation and Perception: Regulatory frameworks and public perception of smoke-free alternatives vary globally. Some countries promote them as harm reduction tools, while others apply strict regulations or bans.

Conclusion
Smoke-free alternatives represent a shift towards reducing the harms associated with smoking by providing safer nicotine delivery methods. While they offer smokers alternatives to traditional cigarettes, ongoing research is essential to evaluate their long-term health effects comprehensively. Regulatory frameworks should balance accessibility for smokers seeking harm reduction with protection for non-users, ensuring informed choices and public health benefits.
