In tobacco products, which chemical is primarily responsible for addiction?

Explanation:
Nicotine is the chemical primarily responsible for addiction in tobacco products. It quickly reaches the brain when tobacco is used, binds to nicotinic acetylcholine receptors, and triggers a surge of dopamine in the brain’s reward pathways. This reinforcement makes using tobacco feel rewarding and leads to habit formation and withdrawal-driven cravings. Tar causes health harms like cancer and lung disease, but it isn’t what drives dependence; water is not addictive, and sugar isn’t the main addictive agent in tobacco.
