ELF Bar can be used as a nicotine replacement therapy. Nicotine replacement therapy is a common method used to help smokers quit smoking. It involves using nicotine products, such as gum, patches, and inhalers, to help smokers manage their nicotine withdrawal symptoms.

Many smokers use Elf Bars (disposable or refillable vapes) as a tool to quit traditional cigarettes, though they are not officially classified as a "smoking cessation medicine." In 2026, health organizations like the NHS in the UK continue to support vaping as a significantly less harmful alternative to combustible tobacco, as it provides the nicotine hit and hand-to-mouth habit without the tar and carbon monoxide. Elf Bars are particularly popular for this because of their high nicotine salt content (often 20mg/ml), which mimics the fast absorption of a cigarette, making the transition easier for heavy smokers. However, "quitting smoking" with an Elf Bar often means transitioning to a "vaping habit" rather than becoming nicotine-free. To successfully quit nicotine altogether, experts recommend a step-down approach: starting with the standard 20mg Elf Bar, moving to 10mg or 0mg options, or switching to a refillable "Elf Bar Elflia" pod system where you can gradually lower the nicotine concentration over several months until you no longer require the device at all.
