Smoking while driving poses cardiovascular and cancer risks

Smoking while driving poses significant health risks to both the driver and those around them. According to Dr. Nguyen Huy Hoang of the Vietnam Underwater and Hyperbaric Medicine Association, cigarette smoke contains over 7,000 chemicals, including approximately 70 carcinogens such as benzene, formaldehyde, and nitrosamine. These substances can damage lung cells, lead to genetic mutations, and are linked to roughly 90% of lung cancer cases. Additionally, smoking can interfere with the body's ability to supply oxygen-rich blood to the heart.

Beyond the driver, secondhand smoke affects others on the road. Passengers on motorcycles are often exposed directly to smoke, while people at crowded intersections or in traffic jams face inhalation risks from the driver's breath and cigarette tip. In cars, the enclosed cabin environment allows fine particles and toxins to spread quickly, and opening windows does not fully eliminate the danger to occupants.
