Tobacco addiction is one of the leading preventable causes of death worldwide. Research has focused on nicotine’s neurobiological effects, cessation methods, and policy measures. This article examines five areas: neurobiology, nicotine replacement therapy, behavioral interventions, e-cigarettes, and public policy.

Key Research Areas

Nicotine Neurobiology

Nicotine binds to nicotinic acetylcholine receptors, reinforcing dependence [1].

Nicotine Replacement Therapy (NRT)

Patches, gums, and lozenges help reduce withdrawal symptoms [2].

Behavioral Approaches

Counseling and motivational interviewing improve quit rates [3].

E-Cigarettes

E-cigarettes are studied both as cessation aids and potential health risks [4].

Policy Measures

Taxation, warning labels, and smoking bans reduce prevalence [5].
