Why Smoking Rates Aren't Falling Fast Enough: The Limits of Conventional Tobacco Control

The MPOWER framework, introduced by the WHO in 2008, is the most successful public health intervention package in modern history. Its six components—monitoring tobacco use, protecting from secondhand smoke, offering cessation help, warning about dangers, enforcing advertising bans, and raising taxes—have been implemented in various combinations by over 150 countries, contributing to a decline in global smoking prevalence from roughly 27% in 2000 to below 20% in 2025. Hundreds of millions of premature deaths have been prevented. The framework is evidence-based, cost-effective, and politically achievable in most contexts. It is also, according to a growing number of tobacco control researchers, approaching the limits of its effectiveness—at least for the smokers who remain. The easy gains have been captured. The remaining smokers are the hard cases, and the MPOWER tools that worked for the easy cases are working less well for them.

The demographic profile of remaining smokers explains why conventional tobacco control is losing momentum. Smoking is increasingly concentrated in populations with characteristics that make cessation harder and conventional interventions less effective: people with mental illness (who smoke at 2–3 times the general population rate and use nicotine to self-medicate psychiatric symptoms), people with substance use disorders (for whom smoking is deeply embedded in addiction culture and often treated as secondary by treatment programs), people living in poverty (who face higher stress, lower access to cessation resources, and environments saturated with tobacco marketing), indigenous populations (for whom smoking is entangled with colonial history and structural marginalization), and people with low educational attainment (who are less reached by health communication and less able to navigate healthcare systems). These populations were always the hardest to reach. As smoking prevalence has declined in the general population, their relative concentration has increased. The same MPOWER measures that worked for the population average are less effective for the populations where smoking is now concentrated.

The MPOWER framework was designed for an era when cigarettes dominated the nicotine market and the policy question was binary: how to reduce smoking. It was not designed for a nicotine landscape where non-combustible alternatives exist at multiple points on a risk continuum, where the industry is diversifying into reduced-risk products, and where the policy question is more complex: how to minimize total nicotine-related harm when different products have dramatically different risk profiles. MPOWER treats all tobacco products as essentially equivalent, with some measures (taxation, advertising bans) applying identically to products with radically different risks. This approach made sense when the product landscape was dominated by cigarettes—there was no lower-risk alternative to discourage. In a diversified nicotine market, it creates perverse incentives: taxing vaping products at the same rate as cigarettes eliminates the price advantage that encourages smokers to switch, and banning vaping advertising while allowing cigarette advertising to continue (in jurisdictions where comprehensive ad bans haven't been implemented) disadvantages the safer product relative to the deadlier one. The framework's binary structure can't accommodate the continuous risk landscape.

The MPOWER framework's reliance on government action creates a ceiling in jurisdictions where government capacity is limited or corrupted by industry influence. The countries with the highest smoking rates and the fastest-growing tobacco epidemics—primarily in sub-Saharan Africa, South Asia, and Southeast Asia—are generally the countries with the weakest governance, the most industry influence, and the least capacity to implement MPOWER measures. Tax increases require administrative capacity to collect taxes and enforce against illicit trade. Advertising bans require regulatory infrastructure and independence from the media companies that carry tobacco advertising. Cessation programs require healthcare systems and funding. The countries that need MPOWER most are the countries least able to implement it, and the implementation gap—between what the framework prescribes and what countries can actually achieve—is widest precisely where the epidemic is growing fastest.

The emerging recognition of MPOWER's limits has generated a search for 'endgame' strategies that go beyond the incrementalism of the original framework. The generational sales ban (New Zealand, UK), the very-low-nicotine cigarette standard (FDA proposal), the retail reduction strategy (limiting tobacco sales to a small number of licensed outlets), and the harm-reduction approach (actively promoting switching to lower-risk products) represent different bets on what comes after MPOWER. These strategies are not mutually exclusive, and the optimal post-MPOWER framework likely combines elements of several. But they share a common recognition: getting smoking from 15% to near-zero in high-income countries, and from 25% to 15% in low-income countries, will require tools that MPOWER doesn't provide. The framework that won the first phase of the tobacco war may not be sufficient to win the second.

The most promising post-MPOWER strategy, from an evidence perspective, is the integration of harm reduction into the tobacco control framework—explicitly encouraging smokers who cannot or will not quit nicotine to switch to non-combustible products, and structuring the market (through differential taxation, honest risk communication, and appropriate regulation) to make that switch as easy and attractive as possible. This strategy directly addresses the MPOWER limitation: it targets the smokers who've been failed by conventional cessation approaches, it leverages the market rather than fighting it, and it creates a pathway to reduced harm that doesn't depend on complete nicotine abstinence. The resistance to this strategy within the tobacco control establishment—rooted in legitimate concerns about industry manipulation and youth uptake—has prevented its incorporation into the MPOWER framework. But the evidence is accumulating that harm reduction reaches populations and achieves outcomes that conventional MPOWER measures, applied alone, cannot.

MPOWER is not obsolete. It's necessary but no longer sufficient. The measures that drove smoking from 27% to 20% will continue to be essential for preventing relapse, discouraging initiation, and maintaining the social denormalization of smoking. But getting from 20% to near-zero, and preventing the epidemic from accelerating in LMICs as the industry targets them, will require adding tools to the toolkit—specifically, harm-reduction strategies that acknowledge the diversity of nicotine products, the concentration of smoking in marginalized populations, and the limits of abstinence-only approaches for the smokers who remain. The MPOWER framework saved hundreds of millions of lives. The question now is whether the tobacco control movement can evolve beyond its most successful strategy to address the smokers it left behind.
