HYPE: Nicotine e-cigarettes increase sustained smoking cessation compared with nicotine replacement therapy in adult smokers.
But what does the evidence actually show?
Nicotine e-cigarettes help more adult smokers achieve sustained smoking cessation than nicotine replacement therapy in the reviewed trials. That specific benefit does not establish long-term safety or support starting vaping if you do not smoke.
The claim
Nicotine e-cigarettes increase sustained smoking cessation compared with nicotine replacement therapy in adult smokers. The rating below applies to this specific outcome and population, rather than every claim associated with the subject.
Why people believe it
A nicotine vape can reduce withdrawal while replacing some of the familiar actions of smoking. Unlike a cigarette, it heats liquid without burning tobacco. These are plausible reasons for its use as a quitting aid; the relevant result is sustained freedom from smoking, rather than simply using fewer cigarettes. [1] [3]
What the evidence actually shows
The latest Cochrane update reports high certainty
The August 2026 review included 80 randomised trials overall. The direct nicotine-vape versus nicotine-replacement comparison used 11 studies with 4,114 participants. Smoking cessation at six months or longer was more likely with nicotine vapes: relative risk 1.61, with a 95% confidence interval of 1.23–2.12. [1]
Relative benefit is different from a success rate
Cochrane translated this to around four additional people quitting per 100 treated, with uncertainty of roughly one to seven more. It does not mean 61% of vape users quit, or that everyone succeeds. Support, the population and baseline quit rates affect absolute results. [1]
Effectiveness and safety are separate questions
A 2026 overview of reviews supports considering nicotine e-cigarettes as a cessation option, while identifying evidence gaps. The same underlying trials can appear in multiple reviews, so agreement is not always independent replication. NHS guidance distinguishes harm reduction for adults who smoke from nicotine initiation by children or non-smokers. [2] [3]
The limitations
The trials do not settle the health effects of decades of vaping. Short-term adverse-event comparisons are not proof of harmlessness, and products containing other active substances cannot be assumed to have the same risk profile. Quitting cigarettes can also leave someone dependent on vaping. [1] [3]
The comparator matters: high certainty applies to cessation versus nicotine replacement in these trials. It should not be copied across every comparison, device or population. For example, evidence against no support has different limitations. [1] [2]
What this means for you
If you smoke and want to stop, discuss the available options with a stop-smoking service or clinician, including licensed medicines and nicotine replacement. Where a vape is chosen, the goal is to stop combustible smoking completely rather than assume ongoing dual use delivers the same benefit. [3]
If you do not smoke, this evidence gives you no reason to start vaping. For someone already using vaping to remain smoke-free, planning eventual nicotine cessation should avoid a return to cigarettes. The appropriate next step depends on the person's circumstances. [3]
