What is the Origin of Nicotine Dependence?

This term originates from clinical psychiatry and addiction medicine, classifying the habitual use of tobacco products or nicotine delivery systems as a pathological dependence. The understanding of its origin is rooted in the neuropharmacology of the nicotinic acetylcholine receptors (nAChRs). Its impact on hormonal health is significant, as chronic use perturbs the HPA axis and systemic inflammation markers.

What is the Mechanism of Nicotine Dependence?

Nicotine acts as an agonist at nAChRs, triggering the rapid release of dopamine in the nucleus accumbens, which reinforces the behavior. Chronic exposure leads to the upregulation and desensitization of these receptors, driving the need for higher doses to achieve the same effect and causing withdrawal symptoms when the substance is absent. This constant neurochemical manipulation disrupts the body's delicate hormonal balance, increasing cortisol and impacting thyroid function.

Nicotine Dependence

Meaning

Nicotine dependence is a chronic, relapsing disorder characterized by compulsive nicotine seeking and use despite harmful consequences, driven by powerful neurobiological adaptations in the brain’s reward system. It is a form of substance use disorder where the psychoactive alkaloid nicotine establishes a profound physiological and psychological need. Clinically, it is recognized by the presence of tolerance, withdrawal symptoms upon cessation, and persistent difficulty in controlling use.
