We built the off-ramp and forgot the gate

Cigarettes are the deadliest consumer product ever sold legally, and the honest history of the last fifteen years is that a lot of people got off them using a device that public health did not invent, did not want, and largely refused to endorse. That is uncomfortable for everybody. It is also the single most useful fact in the file. When an adult smoker of thirty years switches, almost everything that was going to kill them — the tar, the combustion, the carbon monoxide, the particulate load of setting plant matter on fire and inhaling it — stops on the day they switch. The nicotine, which is the part everybody talks about, is the part doing the least damage.

So the first duty of any piece on this subject is to say plainly: if you smoke, switching is a large and immediate improvement, and the widespread public belief that vaping is about as dangerous as smoking is not a cautious position. It is a wrong one, and it has almost certainly kept people on cigarettes. Scaring a fifty-year-old smoker away from an exit does not protect a fourteen-year-old. It just keeps the fifty-year-old smoking.

The second duty is to say the other half without flinching, because the people who love the first half keep skipping it. Nicotine is not benign for an adolescent brain, and the industry that arrived after the early switching devices did not build for smokers at all. It built for adoption: sweet, disposable, cheap, colourful, bought behind a checkbox, thrown in a bin with a lithium cell inside it. A product designed to be pleasant to start is a different product from one designed to be easier to leave than the thing it replaces, whatever the vapour inside it happens to be.

That is the whole of the argument, and it is not a paradox. The device is an off-ramp with an unguarded staircase at the near end. Every serious dispute in this area — flavours, disposables, retail licensing, prescription models, taxation — is really a dispute about how to close the staircase without demolishing the bridge. Framing it as pro-vaping against anti-vaping guarantees the worst outcome available: bans that push adults back to cigarettes and an illicit market that cards nobody.

The countries that have handled this best treated it as a supervision problem rather than a morality problem. Sweden has driven daily smoking to the lowest rate in the European Union — around eight percent against an EU average of twenty-four — largely by letting snus and, later, vaping take the market instead of banning them. New Zealand kept switching legal and cheap while restricting how it is sold to the young, legislating the retail and youth-access rules in 2024 rather than the product itself. The failures went the other way: prohibitions that created a grey market, or a decade of laissez-faire retail where any corner shop could sell a mango disposable to a child with a plausible face.

The unglamorous fixes are the ones that work, and they are all about the point of sale rather than the product. License the retailer, not the flavour, and make the license the thing that dies when they sell to a fifteen-year-old. Test the shops the way alcohol enforcement tests them, publish the pass rates by name, and the compliance problem becomes a commercial one. Ban the single-use disposable — it is the format that made the product cheap enough for a school bag and is an environmental fiasco besides — while keeping refillable devices, which the switching smoker uses anyway, fully available.

And be truthful in the messaging, separately to each audience, because they need opposite things. To the adult smoker: this is much less dangerous than what you are doing now, and here is where to get one. To the sixteen-year-old who has never smoked: this is a nicotine habit you did not need, sold to you by people who modelled your purchasing behaviour. Neither sentence undermines the other. Both being said at once is what an honest health authority sounds like.

The optimistic reading, and we think the correct one, is that this is a solved problem being argued about badly. We have the substitute. It works. What is missing is a gate at the bottom of the stairs, a name on a license, and an adult willing to say two true things in the same paragraph.
