Cigarette and its Composition

In our days cigarettes are produced easier than before. For example today’s machines produce 14,000 cigarettes every minute. Today cigarettes are made easier because the complete procedure is highly automated, and computers do a large amount of the work. Computers don’t need to take a smoke break, that’s why they work night and days.

Apart from tobacco, cigarettes contain paper made of cellulose laden with many added chemicals that serve to give it a whiter appearance, prettier ash, and a smoother burn. The paper is sealed with glue and often contains a monogram made of colored ink.

The cigarette filter is in fact a very complicated structure that is made up of four parts. It consists of fibers bound together by glue, but there are also chemical additives that improve the taste and speed up the rate at which nicotine is delivered to the brain.
Also, there are cigarette filters that make cigarette "light" or "ultra-light" brand. These low tars, low nicotine brands are named in this way because they have filters that contain tiny holes in them. The holes allow outside air to be brought in with each puff of a cigarette, thus diluting the tar and nicotine to lower levels.
These new filtered cigarettes were tested to see if they produced lower levels of tar and nicotine. Special machines were designed that could smoke cigarettes and measure the levels of tar and nicotine in the smoke.
And according to machines the holes worked and the filtered cigarettes delivered lower amounts of tar and nicotine. The problem with this method - still used today - is that people don't smoke like machines.
People have lips and fingers that cover up the holes. Also, people can inhale deeper, take more frequent puffs, and hold the smoke in their lungs longer - which is, in fact, what smokers of "light" brands tend to do.
