Argentina Makes a U-Turn After 15 Years
After 15 years of prohibition, Argentina is changing course. The country is now legalising e-cigarettes, nicotine pouches and heated tobacco products, in a clear acknowledgement that prohibition does not work. At the same time, it raises an important question: is the UK at risk of heading in the opposite direction?
Key Takeaways
- Argentina has reversed its 15-year ban after recognising that prohibition failed to stop demand and instead created a large unregulated and illicit market
- Bans do not eliminate nicotine use – they shift it into informal and less controlled channels, reducing consumer protection and regulatory oversight
- The UK is tightening restrictions, but faces mixed outcomes, including persistent youth use and growing public misperceptions about vaping risks
- Over-restrictive policies risk backfiring by limiting access to less harmful alternatives, potentially slowing the transition away from cigarettes
From Prohibition to Control
Argentina's experience highlights a recurring reality in tobacco policy: strict bans cannot extinguish consumer demand. When restrictions are imposed, the market simply adapts. During Argentina's prohibition era, demand persisted, and access to these products merely shifted to informal and illicit channels, much like we are seeing with disposable vapes in the UK.
The reasoning behind the shift is both straightforward and familiar to many other countries. The ban failed. Authorities recognised that these products continued to be widely available, but without quality standards, traceability or consumer protections. Instead of eliminating their use, the policy had in effect created a large unregulated market.
The new framework therefore aims to take control of an existing reality, rather than trying to deny it.
When Policy Backfires
Argentina highlights a recurring theme in tobacco and nicotine policy. When demand remains, the market survives in one form or another – regardless of how strict the rules are. During the years of prohibition in Argentina, these productscontinued to be used, access simply shifted to informal and often illegal channels.
This is a dynamic that Dr Marina Murphy, Senior Director of Scientific Affairs at Haypp, believes many policymakers underestimate. When access is restricted in ways that do not reflect real-world behaviour, unintended consequences emerge that can ultimately undermine public health goals. As she puts it:
“You don’t make progress by locking the shop door — especially when most of the shelves are already empty.”
Closing a market does not make demand disappear – it simply moves elsewhere.
The UK Moving in the Opposite Direction
While Argentina is liberalising its approach, developments in the UK appear to be heading the other way. The country has long been seen as a leader in pragmatic harm reduction, but in recent years the debate has increasingly focused on tighter restrictions — from bans on disposable vapes to stricter rules on marketing and product design.
The outcomes are far from straightforward. Data shows that adult vaping rates have levelled off, while misperceptions about risk are increasing, with a growing share of people believing vaping is as harmful as smoking. At the same time, youth use has proven difficult to reduce despite stricter measures, suggesting that traditional regulatory tools have limited impact.
“It Protects Cigarettes, Not Public Health”
Dr Marina Murphy has consistently warned about this dilemma. In her view, policy risks missing its core objective if it focuses too heavily on restrictions.
“Restricting adults’ access to adult products doesn’t protect public health – it protects cigarettes.”
The logic is simple, but often overlooked. When access to less harmful alternatives is restricted, smokers are left with the most harmful option still readily available.
Murphy expands on this point:
“If smokers can’t find reduced-risk alternatives easily, they’ll just keep buying cigarettes.”
This is precisely the dynamic Argentina now appears to have recognised, after years of real-world experience showing the limitations of prohibition.
A Step Forward – But Not The Full Solution
At the same time, Argentina’s reform is not a complete shift. The new framework still includes several restrictions, such as flavour bans and limitations on certain product categories.
This means the country is still balancing control with accessibility, and it remains to be seen how effective the new model will be in practice. Experience from other markets suggests that such restrictions can affect how appealing alternatives are to smokers considering switching.
It is a delicate balance. But Argentina’s policy reversal shows what happens when that balance tips too far in one direction. The question now is whether the UK can learn from the lessons from Argentina and other countries now, rather than go through its own lengthy and difficult learning experience first.
