It is now a well-known fact that smoking is harmful.

The government revealed the results of an analysis of the harmful components of cigarette smoke for the first time. The results showed that cigarette smoke includes twelve components that are defined as carcinogens by the International Agency for Research on Cancer.

Lee Jun-heum has more.


Seven Class 1 carcinogens such as formaldehyde and benzene as defined by the International Agency for Research on Cancer were found in the smoke from cigarettes currently sold in the market.

Additionally, there were as many as twelve possibly carcinogenic substances including acetaldehyde and catechol in cigarette smoke.

These are dangerous, life-threatening substances, as a chronic exposure to them could cause leukemia, lower the body's capacity to deliver oxygen, or paralyze the central nervous system.

With nicotine and tar added to the list, the number of toxic substances contained in a single cigarette confirmed by the government alone amounts to forty five.

Carcinogens like formaldehyde were also found even in e-cigarettes which became popular recently.

Liquefied nicotine is used for e-cigarettes. It was found that the amount of toxins increases as much as nineteen times when the liquid turns into gas.

Following this unprecedented release of the information on cigarette toxins, the government plans to investigate whether or not the substances affect the human body and also announce the result.
