Nicotine and smoke
Cigars contain nicotine, a substance that can cause addiction. Cigar smoke contains chemicals known to cause cancer. A person does not have to inhale deeply to face all of the health risks associated with cigar use.
Secondhand exposure
People who do not smoke can also be exposed to harmful substances in secondhand tobacco smoke. Public-health guidance addresses both individual use and exposure in shared environments.
