Tobacco is a leafy plant grown around the world, including in the United States. Its leaves 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. There are also many other potentially harmful chemicals found in tobacco or created by burning it.

Tobacco and nicotine is found in the following products:

• Smokable products: cigarettes, cigars, cigarillos, bidis.
• Vaping products: e-cigarettes, vape pens, hookah,
• Smokeless products: snus, snuff, chew, spit, dip, dissolvable tobacco

While adolescent cigarette use has generally declined, sharp increases in e-cigarette and hookah tobacco use have offset progress overall.
