Some who are trying to quit smoking or vaping will use nicotine gum or skin patches. These give them a smaller dose of nicotine that might help make quitting for good a little easier.
nicotine : A colorless, oily chemical produced in tobacco and certain other plants. It creates the “buzz” associated with smoking. Highly addictive, nicotine is the substance that makes it hard for smokers to give up their use of cigarettes. The chemical is also a poison, sometimes used as a pesticide to kill insects and even some invasive snakes or frogs.
People take in nicotine in many ways. Many inhale it in smoke or vapor from cigarettes, cigars, pipes, hookahs or e-cigarettes. Others chew it in chewing tobacco. Almost 40 million adults in the United States smoke cigarettes. Another 4.7 million teens use a nicotine-containing product — usually cigarettes or vaping pods .
If teens use vaping liquid with high levels of nicotine , they are more likely to become smokers. Check out the full list of Scientists Say .

vaping : A slang term for the use of e-cigarettes because these devices emit vapor, not smoke. People who do this are referred to as vapers.
addictive : An adjective to describe something that become habit-forming in an uncontrolled or unhealthy way. This can include a drug or some habit . Such addictions reflect an illness triggered by brain changes that occur after using some drugs or engaging in some extremely pleasurable activities. People with an addiction will feel a compelling need to use a drug , even when the user knows that doing so risks severe health or legal consequences.

smoking : A term for the deliberate inhalation of tobacco smoke from burning cigarettes.
Nicotine is an addictive substance found mostly in tobacco plants. In plants, it functions as an insecticide — poisoning insects that try to eat the plant. Humans, however, get very different effects from nicotine. It stimulates them, or makes them more alert. It relaxes them too. Unfortunately, nicotine is extremely addictive. The more someone uses it, the more they crave its effects. That makes it harder and harder to stop using it.
smoke : Plumes of microscopic particles that float in the air. They can be comprised of anything very small. But the best known types are pollutants created by the incomplete burning of oil, wood and other carbon-based materials.
insect : A type of arthropod that as an adult will have six segmented legs and three body parts: a head, thorax and abdomen. There are hundreds of thousands of insects, which include bees, beetles, flies and moths.
hookah : A water pipe used to cool smoke — usually tobacco smoke — that will be inhaled. According to the U.S. Centers for Disease Control and Prevention, “hookah smoking carries many of the same health risks as cigarettes.”
tobacco : A plant cultivated for its leaves, which many people burn in cigars, cigarettes, and pipes. Tobacco leaves also are sometimes chewed. The main active drug in tobacco leaves is nicotine, a powerful stimulant .
e-cigarette : Battery-powered device that disperses nicotine and other chemicals as tiny airborne particles that users can inhale. They were originally developed as a safer alternative to cigarettes that users could use as they tried to slowly break their addiction to the nicotine in tobacco products. These devices heat up a flavored liquid until it evaporates, producing vapors. People use these devices are known as vapers.
liquid : A material that flows freely but keeps a constant volume, like water or oil.
