Every year on May 31st, the World Health Organization designates World No Tobacco Day to raise awareness of the devastating health effects of tobacco use.
Why is smoking so dangerous?
Smoking harms not only the smoker but also those nearby who inhale secondhand smoke. Cigarette smoke contains harmful substances and over 42 known carcinogens. The three most significant are:
- Carbon monoxide — a primary contributor to heart disease.
- Nicotine — raises blood pressure, causes irregular and accelerated heart rate, constricts blood vessels in the arms and legs, and increases fat buildup in the arteries.
- Tar — a carcinogen linked to cancers of the lung, larynx, bronchi, esophagus, kidneys, and bladder.
The bottom line
Smoking is one of the leading causes of preventable illness and premature death. Quitting at any age reduces health risks and is one of the most impactful decisions a person can make for their long-term wellbeing.
