Although no Federal agency formally defined the range of tar yield for light or ultralight cigarettes, the tobacco industry used the ranges shown in the table below 5 , 7. These ratings were not an accurate indicator of how much tar a smoker might have been exposed to, because people do not smoke cigarettes the same way the machines do and no two people smoke the same way. Ultralight and light cigarettes are no safer than full-flavor cigarettes.
There is no such thing as a safe cigarette 1. The ratings cannot be used to predict how much tar a smoker will actually get because the way the machine smokes a cigarette is not the way a person smokes a cigarette. A rating of 7 milligrams does not mean that you will get only 7 milligrams of tar. You can get just as much tar from a light cigarette as from a full-flavor cigarette.
It all depends on how you smoke. Taking deeper, longer, and more frequent puffs will lead to greater tar exposure. Cigarette features that reduce the yield of machine-measured tar also reduce the yield of nicotine. Because smokers crave nicotine, they may inhale more deeply; take larger, more rapid, or more frequent puffs; or smoke extra cigarettes each day to get enough nicotine to satisfy their craving.
As a result, smokers end up inhaling more tar, nicotine, and other harmful chemicals than the machine-based numbers suggest 1. Tobacco industry documents show that companies were aware that smokers of light cigarettes compensated by taking bigger puffs. Industry documents also show that the companies were aware of the difference between machine-measured yields of tar and nicotine and what the smoker actually inhaled 8.

Social Media. The smoke from these products is a complex mixture of chemicals produced by burning tobacco and its additives. Tobacco smoke is made up of thousands of chemicals, including at least 70 known to cause cancer. These cancer-causing chemicals are referred to as carcinogens.
Some of the chemicals found in tobacco smoke include:. Many of these substances cause cancer. Some can cause heart disease, lung disease, or other serious health problems, too. Most of the substances come from the burning tobacco leaves themselves, not from additives included in cigarettes or other tobacco products.
Radioactive materials are in the tobacco leaves used to make cigarettes and cigars. These materials come from the fertilizer and soil used to grow the tobacco leaves, so the amount in tobacco depends on the soil the plants were grown in and the type of fertilizers used. And because they are thinner than regular cigarettes, they require about 3 times as many puffs per cigarette. Some people think they are safer and more natural than regular cigarettes. But bidis appear to have all of the same health risks of regular cigarettes, including many types of cancer.
People who smoke bidis have much higher risks of heart attacks, emphysema, chronic bronchitis, and cancer than those who don't smoke bidis. Hookah is also called narghile NAR-guh-lee smoking. It started in Asia and the Middle East.
A water pipe is used to burn tobacco that has been mixed with flavors such as honey, mint, licorice, molasses, or fruit, and the flavored smoke is inhaled through a long hose. Usually, the tobacco mixture, which is called shisha SHE-shuh , is heated using charcoal.
The charcoal itself produces carbon monoxide and other toxins. Hookah smoking has become popular among younger people in the US as a social event which lets them spend time together and talk as they pass the mouthpiece around. Newer forms of hookah smoking include steam stones that have been soaked in fluid and are used instead of tobacco and battery powered hookah pens.
Hookah pens work the same way as electronic or e-cigarettes [see Electronic or e-cigarettes vaping devices ]. Some sellers advertise that these are purer and healthier alternatives to regular hookahs, but this has not been proven. Hookahs are marketed as a safe alternative to cigarettes. This claim is false. The water does not filter out the toxins. In fact, hookah smoke has been shown to contain toxins like carbon monoxide, nicotine, tar, and heavy metals, in concentrations that are as high, or even higher, than those in cigarette smoke — it carries many of the same health risks.
But because the use of hookahs is generally less frequent than the use of cigarettes, it is likely that a person's overall exposure to the toxic ingredients is less. Several types of cancer, including lung cancer, have been linked to hookah smoking. It affects the heart, too, causing coronary artery disease, an increased heart rate, and high blood pressure.
Lung damage, carbon monoxide intoxication, chronic bronchitis, emphysema, dental problems, and osteoporosis have also been linked to hookah use.
