Does nicotine cause cancer?

Nicotine itself is not considered a carcinogen. Carcinogens are substances known to cause cancer, and nicotine does not fall into this category. However, nicotine is an addictive chemical found in tobacco products, including traditional cigarettes as well as E-cigarettes or vapes.

While nicotine is not carcinogenic, it's important to note that the way people consume nicotine, such as through smoking tobacco cigarettes, exposes them to many harmful chemicals and carcinogens present in tobacco smoke. These other substances in tobacco smoke are responsible for the increased risk of various cancers associated with smoking, not the nicotine itself.

In summary, nicotine alone is not a carcinogen, but it is highly addictive, and the health risks associated with nicotine use are primarily due to the method of delivery, such as smoking tobacco, and exposure to the harmful byproducts of combustion.
