There is a puzzle at the heart of the vaping boom. Many of today’s regular vapers never smoked, dislike cigarette smoke, and started with a device they assumed was mild. Yet within months, some are using it hundreds of times a day. Chemists and addiction specialists say the explanation sits in two words: nicotine salts.
Freebase versus salts: a quick chemistry lesson
Traditional e-liquids used what is called freebase nicotine. At high strengths, freebase is harsh on the throat, which naturally limited how much a user, especially a beginner, could inhale. Nicotine salts are made by adding a mild acid, commonly benzoic acid, which lowers the pH of the vapour. The result is a high-strength nicotine hit that feels smooth rather than scratchy. A new user can take in as much nicotine as a cigarette delivers, sometimes more, without the coughing fit that once acted as a warning light.
Strength without the signal
That smoothness changes behaviour. Because there is little discomfort, people vape more often, in more places, and for longer sessions. Small disposable devices are designed for exactly this pattern: no buttons, no refilling, just hundreds of puffs available in the pocket at any moment. The NHS and other health authorities note that while vaping is used as a quitting tool by many smokers, the same products carry real dependence risks for people who have never smoked, for whom there is no health benefit to offset them.
Flavour and social proof finish the job
Salts explain the pharmacology, but not the whole story. Sweet flavours make the vapour pleasant, social media makes it look normal, and stress does the rest: a device that promises a quick pause becomes part of study breaks, commutes and late-night work sessions. Cessation experts describe clients who began with a friend’s vape at a party and now cannot concentrate through a film without theirs.
How people break the pattern
The good news is that the exit routes are well mapped. Specialists advise stepping down nicotine strength gradually or setting a firm quit date, using regulated nicotine replacement products to blunt cravings, and expecting the first two weeks to be the hardest. Support services, including free quit lines and local stop-smoking clinics, exist for vapers as much as smokers, and using them roughly doubles the chance of quitting for good. Telling friends matters too, because shared devices are the most common route back in.
Labels that hide the strength
Part of the problem is communication. Nicotine strength is printed in milligrams per millilitre or as a percentage, numbers that mean little to a first-time buyer. A 5 per cent pod sounds modest; in practice it sits at the strong end of the market. Health campaigners have long argued for clearer, cigarette-equivalent labelling, so that a buyer can see at a glance that a small device may deliver nicotine comparable to a full packet of cigarettes. Until that happens, the burden falls on the user to research what they are inhaling, and on retailers to explain it honestly. If you are buying a product whose strength you cannot interpret, that confusion is itself useful information: the product was not designed with your understanding in mind.
One final point deserves emphasis. Vaping products were introduced, and are still defended, as a less harmful alternative for adult smokers, and for that group the calculus is genuinely different. The concern in this article is the second, unintended audience: people with no smoking history for whom the product offers risk without any offsetting benefit. Keeping those two audiences separate, in regulation, in retail and in conversation, is the task health policy is now wrestling with.
