UK-backed, Cochrane-supported, structured three-phase approach.

Yes vaping can help reduce cigarette dependence and the UK public health position on this is unusually clear. Public Health England plus its successor organisation the Office for Health Improvement and Disparities (OHID) have both published guidance stating vaping is substantially less harmful than smoking plus recommending vaping as a smoking cessation tool. The NHS actively supports vaping as a quit aid including through the Swap to Stop programme that offers free starter kits to smokers in England. Here is the full picture of what the evidence says, how vaping actually helps people quit plus practical guidance on using vape to reduce cigarette dependence.

The UK public health position

The UK approach to vaping is different from most other countries. Several specific positions have been consistently held by UK public health bodies since 2015:

• Vaping is estimated to be around 95 per cent less harmful than smoking. Originally published by Public Health England in 2015, this estimate has been maintained across subsequent reviews and remains in current NHS materials.
• Smokers should be encouraged to switch to vaping if they cannot quit nicotine entirely. This is a harm reduction position. Complete cessation remains the ideal but switching is seen as meaningful progress.
• NHS Stop Smoking services include vaping advice. Advisors discuss vaping alongside patches, gum plus lozenges as options for smokers wanting to quit.
• The Swap to Stop programme offers free vape starter kits. Launched in 2023 and expanded since, the programme provides free vape kits to adult smokers in England to support the switch.

The evidence base

The most authoritative recent source is the 2024 Cochrane Review on electronic cigarettes for smoking cessation. The Cochrane Reviews are considered the gold standard for medical evidence synthesis. Key findings from the 2024 review included:

• High-certainty evidence that nicotine-containing e-cigarettes increase quit rates compared with nicotine replacement therapy (NRT).
• Approximately 8 to 10 per 100 people who use vaping to quit successfully stop smoking compared to 6 per 100 using traditional NRT.
• No clear evidence of serious adverse effects from vaping in the short to medium term.
• The evidence base continues to strengthen as more studies are published.

Additional UK-specific research from the Smoking in England initiative, King's College London evidence reviews plus NHS England evaluation of the Swap to Stop programme consistently support similar conclusions.

Why vaping works for quitting

Vaping addresses both the chemical plus the behavioural dimensions of smoking dependence which is why it tends to work better than options that only address the chemical side.

Chemical: nicotine delivery. The addictive component of smoking is nicotine. Vapes deliver nicotine in a form that the body absorbs efficiently plus that matches the typical nicotine profile of cigarettes for many users. This resolves the physiological cravings that make quitting hard.

Behavioural: the hand-to-mouth action. A huge part of smoking dependence is the ritual: the hand-to-mouth movement, the inhale, the social context. Patches and gum deliver nicotine but do nothing for the behavioural dimension. Vaping closely replicates the smoking ritual which makes the transition feel less abrupt.

Sensory: the throat hit. Many ex-smokers describe the throat hit of vaping as a key reason they successfully switched. The sensation mimics the feeling of smoking well enough to satisfy the sensory expectation.

The structured switch and step-down approach

The NHS Stop Smoking framework plus most published vaping quit research support a phased approach:

• Phase 1 (Weeks 1-4): Dual use tapering down. Start vaping while still smoking. Use the vape whenever you would otherwise smoke. Over two to four weeks, cigarettes naturally reduce as vape satisfies the craving more reliably. Some people drop smoking immediately. Others take a few weeks.
• Phase 2 (Months 1-6): Vape only. Fully switched to vaping, usually at 20mg nic salt strength for heavy ex-smokers or 10mg for lighter ex-smokers. The goal of this phase is establishing stable non-smoking life.
• Phase 3 (Months 6-12): Step down strength. Gradually reduce nicotine strength over months. 20mg to 10mg. 10mg to 5mg. 5mg to 3mg. 3mg to zero-nicotine vape or fully stopped. Exact pace varies by individual.

Some people complete the full journey to nicotine-free in 6 months. Others take 18 months or more. Both are valid. The key is progress not speed.

Nicotine strength guide for quitters

• 20+ a day smokers. Start at 20mg nic salt. This matches the nicotine level of heavy smoking. Pod systems are usually the best fit.
• 10-20 a day smokers. Start at 20mg nic salt. Some find 10mg works too but 20mg reduces the risk of unsatisfied cravings pulling you back to cigarettes.
• 5-10 a day smokers. Start at 10mg nic salt. 20mg may be too strong.
• Less than 5 a day. 5mg may be sufficient. Lighter smokers often find lower strengths satisfy cravings without excessive nicotine exposure.

Our nicotine salts collection covers every UK compliant strength from 20mg down to 3mg so you can start at the right level plus step down at your own pace.
