Nicotine Replacement Therapy — What It Is and How It Compares to Gradual Reduction

Nicotine replacement therapy (NRT) is a medical treatment that delivers controlled, low doses of nicotine through patches, gum, lozenges, inhalers, or sprays to reduce withdrawal symptoms when quitting smoking.

What is Nicotine Replacement Therapy (NRT)?

Nicotine replacement therapy provides nicotine through a non-tobacco delivery mechanism to ease withdrawal while a person stops or reduces smoking. The most common forms are transdermal patches (slow, steady release), gum and lozenges (faster release for acute cravings), nasal and oral sprays, and inhalers. NRT approximately doubles the success rate compared to quitting without any support. It is available over the counter in most countries and is considered safe for most adults. NRT addresses the physical side of dependence but not the behavioral or psychological habits associated with smoking.

  • Patch: 16–24 hour steady-release, best for all-day cravings
  • Gum/Lozenge: fast-acting, best for acute craving control
  • Inhaler: mimics the hand-to-mouth action of smoking
  • Spray: fastest-acting NRT option
  • Can be combined (patch + gum) for heavier smokers
