What should you know about nicotine dependence?

Nicotine changes the brain's reward and stress systems. Dependence may show up as needing nicotine soon after waking, finding it hard to cut down, or continuing to use it when it affects breathing, circulation or daily routines. When nicotine levels fall, irritability, anxiety, restlessness, poor concentration and strong urges can appear. These symptoms reflect withdrawal rather than a lack of willpower. Nicotine can come from cigarettes, vaping products, shisha or other products.

Choose a quit date or begin by tracking when and why you use nicotine. Remove products and identify triggers such as coffee, driving, social situations or stress. A clinician or pharmacist can discuss nicotine replacement and other stop-smoking support. A smoking cessation programme can add coaching, coping strategies and follow-up. If you slip, treat it as information about a trigger and restart the plan rather than abandoning it.

Arrange medical support if cravings repeatedly derail attempts, withdrawal is affecting sleep or work, or you use nicotine while pregnant or managing a long-term illness. Seek urgent help for severe chest pain, sudden trouble breathing, fainting or new weakness on one side. A persistent cough or leg pain when walking also deserves assessment; nicotine dependence can coexist with conditions such as Chronic Cough, COPD or Peripheral Arterial Disease.

Ask which quit approach fits your nicotine use, what withdrawal symptoms to expect, how to manage cravings at work or home, and what follow-up support is available.
