What is Nicotine?

Nicotine, recognized as one of the most frequently used addictive drugs, is a naturally occurring colorless liquid that turns brown when burned and acquires the odor of tobacco when exposed to air.

Depending on how tobacco is taken, nicotine can reach peak levels in the bloodstream and brain rapidly.

How Does Tobacco Affect the Brain?

Like cocaine, heroin, and marijuana, nicotine increases levels of the neurotransmitter dopamine, which affects the brain pathways that control reward and pleasure.

Smoking During Pregnancy--What are the Risks?
