Nicotine Replacement Therapy (NRT)

Nicotine replacement therapy (NRT) supplies controlled doses of nicotine without tobacco smoke, easing withdrawal symptoms and cravings while a person quits. Forms include patches, gum, lozenges, mouth sprays and inhalators, which can be combined for stronger effect.

In Australia, NRT is available in pharmacies and supermarkets, and some forms are PBS subsidised on prescription. Evidence shows NRT works best alongside behavioural support, which is why structured quit smoking consultations pair it with a personalised quit plan.
