How to Quit Smoking: What Actually Works (A Pharmacist’s View)

Most people who quit smoking for good didn’t manage it on willpower alone — and they didn’t manage it first try either. The evidence is clear: using nicotine replacement therapy (NRT) with a bit of support roughly doubles your chances of quitting compared to going cold turkey.

Why quitting feels so hard

Nicotine withdrawal peaks in the first 72 hours: irritability, poor concentration, cravings that feel urgent but pass in 3–5 minutes. NRT works by taking the edge off that withdrawal while you break the habit itself — the cup-of-tea cigarette, the break-time smoke.

Choosing your NRT

Patches — the steady base

A nicotine patch gives a slow, constant level through the day. Start at the strength matching how much you smoke and step down over 8–10 weeks.

Gum, lozenges and spray — the rapid rescue

Nicotine gum, lozenges or the Quickmist spray handle sudden cravings. Most successful quitters use a patch plus a fast-acting product together — that combination is safe and more effective than either alone.

Your first week, planned

  • Pick a quit date — ideally a calm week, and tell people
  • Clear the house of cigarettes, lighters and ashtrays the night before
  • Patch on first thing each morning; gum or spray in your pocket
  • Change the routine around your trigger moments — different chair, different route, tea instead of coffee
  • Count the money — a 20-a-day habit is around €450 a month back in your pocket
