What is the material ingredients for cigarettes?

Cigarettes has been known since 9th century around Central America and Mexico. The Maya and Aztect, has been used cigarettes or its predecor the cigar for ritual purpose. The name cigarettes itself first announced when it is transported to France in 1830, since then cigarettes began manufactured.

Cigarettes is made by rolling tobacco leaves in a thin paper. One side being ignited and from the other side people can inhale the smoke. This tradition keep going and it is showing up that not only men that smoke but also women. The number of women who smoke keep increase from late 80s until now.

What’s make the cigarettes become an issue is because of the side effect from smoking cigarettess. From health issue until environment issue, many people has been contrary with cigarettes. Campaign mostly come up for health awareness. This happen because many studies already said that cigarettes composed by a dangerous component, which is nicotine, tar, and carbon monoxide.

  1. Nicotine, is one of the most ingredients found in cigarettes. nicotine has a nature addictive. It can cause blood presure, surge of heart rate, and also adrenaline which cause addiction because it feels good. But this chemical compounds is easily absorbed in blood and brain making the smoker condition worsen day by day.
  2. Tar, is a sticky and thick substances. Tar will infect the tiny hair on the lungs called cilia. Cilia function is to protect and to filter lungs from dirt, but when sticky tar covered up cilia, it will not able to do their job.
  3. Carbon monoxide, usually found in car exhaust. It is categorized as dangerous because it can decrease the amount of oxygen in the blood which will cause heart to work harder than usual.

Not only that new studies have been proved that cigarettes is one of the important reason in increasing number of cancer and tumor patient. Because except those three dangerous chemical compounds there are exist several dangerous component that contain chemicals in cigarettes that cause cancer.

NNK is also cateogorized as mutagen, it caused change in human genome, or called it as polymorphisms. It usually involve cells such as cell growth, proliferation, and differentiation. NNK effect can be seen in gene silencing, function distruption, carcinogenesis, and the new studies said it also cause tumorigenesis. The amount of NNK in cigarettes is equal to 110 to 133 ng.

  1. N– Nitrosonornicotine ( NNN)

N– Nitrosonornicotine or NNN, together with NNK is considering as the most carcinogenic, means they are the one who responsible for many cancer cases from smoking tobacco. NNN is produced from the burning process of tobacco, mostly found in the smoke and human saliva after consuming tobacco. It is also produced from nicotine. NNN will bind with nucleotide, forming a DNA adduct or a DNA segmentation that causing a cancer. The effect is a rapid and uncontrolled growth of cancer and tumor cells.

N– Nitrosonornicotine formula: C9H11N3O

Effect of N– Nitrosonornicotine:

  1. Nasal cancer
  2. Oral cavity cancer
  3. Esophagus cancer
