Electronic cigarettes, also known as e-cigarettes or e-vaporizers, are battery-operated devices that deliver nicotine with flavorings and other chemicals to the lungs in vapor instead of smoke.
E-cigarette companies often advertise them as safer than traditional cigarettes because they don't burn tobacco.
Nicotine is poisonous and, though uncommon, overdose is possible.
An overdose occurs when the person uses too much of a drug and has a toxic reaction that results in serious, harmful symptoms or death.
Chewed tobacco products include chewing tobacco, snuff, dip, and snus; snuff can also be sniffed.
The nicotine in any tobacco product readily absorbs into the blood when a person uses it.
For example, people who hang out with others who smoke are more likely to smoke and less likely to quit.

They target nicotine receptors in the brain, easing withdrawal symptoms and blocking the effects of nicotine if people start smoking again.Tobacco is a plant grown for its leaves, which are dried and fermented before being put in tobacco products.Tobacco contains nicotine, an ingredient that can lead to addiction, which is why so many people who use tobacco find it difficult to quit.It increases the risk of heart disease, which can lead to stroke or heart attack.Smoking has also been linked to other cancers, leukemia, cataracts, and pneumonia.
