Tobacco kills around 78,000 people in the UK every year — more than alcohol, road accidents and all other recreational drugs combined. Quitting is difficult because nicotine is genuinely, powerfully addictive. But with the right support, 1 in 3 people who attempt to quit with NRT succeed — compared to around 1 in 20 without any support.
The Neuroscience of Nicotine Addiction
Nicotine crosses the blood-brain barrier within seconds of inhalation and binds to nicotinic acetylcholine receptors, triggering a surge of dopamine in the nucleus accumbens — the brain’s reward centre. This produces an immediate pleasurable effect that the brain rapidly learns to seek again. Over time, the brain upregulates (produces more) nicotinic receptors to compensate, creating a state of neurochemical dependence where normal functioning requires nicotine. Quitting triggers a withdrawal syndrome: irritability, anxiety, difficulty concentrating, insomnia, increased appetite and intense cravings — all driven by the absence of nicotine’s effects on brain chemistry.
Which NRT Is Right for You?
Patches provide a steady, continuous nicotine level — the best option for those who primarily need craving prevention rather than acute relief. Step down: 21mg for 6 weeks, 14mg for 3 weeks, 7mg for 3 weeks. 24-hour patches prevent morning cravings; 16-hour patches reduce sleep disruption in those who experience vivid dreams. Gum provides a faster nicotine hit for acute cravings. Correct technique: “chew and park” — 6 chews, then park between cheek and gum until tingling fades (typically 30 seconds), chew again. Don’t swallow nicotine-laden saliva. Available in 2mg (under 20 cigarettes/day) and 4mg (over 20 or strong craving). Lozenges dissolve slowly for 20–30 minutes; good option for those with dental problems. Mouth spray — fastest-acting NRT, delivering nicotine to oral mucosa in seconds. Nicorette QuickMist. Excellent for sudden, intense cravings. Inhalator — cigarette-shaped device with nicotine cartridge. Mimics the physical ritual of smoking, which many people find supports the psychological aspect. Combination NRT — patch (background) + fast-acting product (rescue) is the most effective strategy, doubling quit rates compared to either alone.
Prescription Options
Varenicline (Champix) — partial nicotinic receptor agonist; the most effective pharmacological quit aid. Bupropion (Zyban) — an antidepressant with significant quit-rate benefits. Both require prescription and are available via NHS Stop Smoking services.
