Tar. Tar is the sticky brown substance that stains smokers' teeth and fingers yellow-brown. It contains cancer causing particles (carcinogens). Tar damages your lungs by narrowing the small tubes (bronchioles) that absorb oxygen.
Two of the major agents in smoke that can cause health effects are carbon monoxide gas and very small particles (fine particles, or PM2.5 ). These particles are two and one half (2.5) microns or less in size (25,400 microns equal an inch) and individual particles are too small to be seen with the naked eye.
When burned, cigarettes create more than 7,000 chemicals. At least 69 of these chemicals are known to cause cancer, and many are toxic. Many of these chemicals also are found in consumer products, but these products have warning labels—such as rat poison packaging.
Hookah smoke has high levels of harmful chemicals. These include tar, carbon monoxide, heavy metals and cancer-causing chemicals called carcinogens. In fact, hookah smokers are exposed to more carbon monoxide and smoke than are cigarette smokers.
1: Vaping is less harmful than smoking, but it's still not safe. E-cigarettes heat nicotine (extracted from tobacco), flavorings and other chemicals to create an aerosol that you inhale. Regular tobacco cigarettes contain 7,000 chemicals, many of which are toxic.

Arsenic-containing pesticides used in tobacco farming occur in small quantities in cigarette smoke. Arsenic is commonly found in rat poison. Ammonia is a toxic, colourless gas with a sharp odour. Ammonia compounds are commonly used in cleaning products and fertilisers.
toxic chemicals such as benzene, arsenic and formaldehyde.
Are e-cigarettes less harmful than regular cigarettes? Yes—but that doesn't mean e-cigarettes are safe. E-cigarette aerosol generally contains fewer toxic chemicals than the deadly mix of 7,000 chemicals in smoke from regular cigarettes.
There is no safe smoking option — tobacco is always harmful. Light, low-tar and filtered cigarettes aren't any safer — people usually smoke them more deeply or smoke more of them. The only way to reduce harm is to quit smoking.
Pure nicotine can be lethal in sufficient quantities. There is some evidence it may lead to changes in adolescent brain development, especially to the part responsible for intelligence, language and memory.
Tobacco smoke
Here's a list of just a few of the chemicals found in cigarette smoke: Acetone - found in nail polish remover. Acetic Acid - an ingredient in hair dye. Ammonia - household cleaner.
Nicotine can reach peak levels in the bloodstream and brain rapidly, depending on how it is taken. Cigarette smoking results in nicotine reaching the brain within just 10 seconds of inhalation!
The long-term risks of vaping are not yet clear. E-cigarettes do not produce tar or carbon monoxide, two of the most harmful elements in tobacco smoke. The liquid and vapour contain some potentially harmful chemicals also found in cigarette smoke, but at a much lower level.
In 1880 James A. Bonsack was granted a U.S. patent for a cigarette machine in which tobacco was fed onto a continuous strip of paper and was automatically formed, pasted, closed, and cut to lengths by a rotary cutting knife. The Bonsack machine was imported to England in 1883.
Cigars contain the same toxic and carcinogenic compounds found in cigarettes and are not a safe alternative to cigarettes.
Why Are Cigarettes, E-Cigs, and Other Tobacco Products So Hard to Quit? Nicotine. Tobacco products are addictive because they contain nicotine. Nicotine keeps people using tobacco products, even when they want to stop.
Tar contains most of the cancer-causing and other harmful chemicals found in tobacco smoke. When tobacco smoke is inhaled, the tar can form a sticky layer on the inside of the lungs. This damages the lungs and may lead to lung cancer, emphysema, or other lung problems.
During manufacturing, ammonia—a chemical found in household cleaning products—along with other chemicals may be added to increase nicotine absorption. Sugar and flavor additives may also be added during this stage to mask the harshness of smoke. These additives form cancer-causing chemicals when they are burned.
“Smoking as few as five days per month can lead to shortness of breath and coughing. And smoking one to four cigarettes per days can increase your risk of heart disease and cancer." Light smokers also have a higher risk of lung cancer than nonsmokers.
Vaping exposes users to fewer toxins and at lower levels than smoking cigarettes. Switching to vaping significantly reduces your exposure to toxins that can cause cancer, lung disease, and diseases of the heart and circulation like heart attack and stroke.
Conclusions Smoking only about one cigarette per day carries a risk of developing coronary heart disease and stroke much greater than expected: around half that for people who smoke 20 per day. No safe level of smoking exists for cardiovascular disease.
