Overview of Nicotine
What is Nicotine?
Nicotine is a chemical derived from the tobacco plant. Nicotine is a toxic and highly addictive stimulant drug.
Typical Nicotine Products
Nicotine is typically delivered to users through tobacco products, such as cigarettes, hookah, or smokeless tobacco, and more recently has been available in a non-tobacco form delivered through electronic cigarettes or e-cigs. It may also be administered for short periods in the form of FDA regulated Nicotine Replacement Therapy (NRT) via gum, patch, or lozenge as part of tobacco cessation treatment.
The Danger of Nicotine
While nicotine alone is a dangerous substance, it is also often combined with other chemicals, making the use of nicotine and tobacco products even more unhealthy.
The Addictiveness of Nicotine
The addictiveness of nicotine is equivalent to if not greater than cocaine and heroin, making it the most addictive substance known to humans.
