Healthy Youth, Strong Zambia: Protecting the Next Generation Through Health Taxes

The tobacco industry has never needed to persuade a sixty-year-old to take up smoking. Its entire commercial model rests on a much younger customer — one who begins in secondary school, forms a habit before the age of twenty, and then spends four decades paying for a decision made in adolescence. The same logic governs the marketing of cheap spirits in sachets and sugary drinks sold at pocket-money prices outside school gates. Whoever captures the young captures the market for a generation.

This is why the health of Zambia's young people is not a niche concern within public health. It is the whole game. Roughly two-thirds of our population is under twenty-five. The habits formed in those years will determine the disease burden this country carries in 2050, the productivity of its workforce, and the size of the health bill our children will be asked to pay. Nothing else in health policy has that leverage.

Protect a fifteen-year-old from one purchase today and you may have protected an adult for the next fifty years.

Fortunately, the same feature that makes young people vulnerable also makes them protectable. Adolescents have the least disposable income of any group of consumers, which makes them the most sensitive to price. When the cost of a packet of cigarettes rises, the adult smoker often absorbs it; the schoolchild simply cannot. Studies across many countries find that young people respond to price increases two to three times more strongly than older users. A tax that inconveniences an adult can be decisive for a teenager — and a habit not started is a habit that never has to be broken.

Price is only the first line of defence, though, and it works best in company. Where cigarettes can be bought as single sticks, a price rise loses much of its force, because the unit a young buyer purchases stays affordable. Where spirits are sold in small sachets, the same problem appears in a different form. Where advertising, sponsorship and point-of-sale display are unrestricted, the aspiration to consume is manufactured faster than any tax can suppress it. A coherent strategy raises the price, removes the small pack, clears the shop counter, and keeps the school perimeter free of promotion.

Sugary drinks deserve their own attention, because the harm is slower and therefore easier to dismiss. A child who drinks a litre of soft drink a day is not visibly unwell, and no one calls it an addiction. But rising rates of childhood obesity and early-onset type 2 diabetes tell a different story, and they arrive in a health system already stretched by infectious disease. Diabetes diagnosed at twenty-five is a lifetime of medication, of complications, of clinic visits during working hours. It is one of the most expensive conditions a poor country can allow itself to acquire at scale.

There is a further reason to act early that has nothing to do with disease statistics. Young people who grow up healthy learn better. Concentration, attendance and school completion all depend on health in ways that are easy to overlook when we discuss education policy in isolation. A country cannot educate its way to prosperity while quietly undermining the physical and mental condition of the students it is educating. Health policy and education policy are the same investment approached from two directions.

Revenue raised from health taxes should therefore be visibly reinvested where young people can see it: school health programmes, mental health support for adolescents, safe recreation spaces, sports facilities, clean drinking water in schools so that a soft drink is not the most reliable option available. This is what turns a tax from a restriction into a bargain. We are asking harmful products to fund the alternatives to themselves.

Young people should also be participants in this work rather than its subjects. The most persuasive advocates against tobacco marketing are the students who can describe how it reaches them — through influencers, sponsored events, flavoured products and shopfront displays that adults never notice. Give them the evidence and a platform and they will argue the case more convincingly than any ministry brief. That is not a token gesture; it is a recognition that they understand the marketing environment better than we do.

A country's future is not decided in its parliaments alone. It is decided in the small, repeated choices made by fifteen-year-olds on their way home from school — and in whether the adults around them have made the harmful choice expensive and the healthy one easy. Zambia's greatest resource is the generation now sitting in its classrooms. Protecting them is not a cost to be justified. It is the highest-return investment available to us, and the window in which to make it does not stay open for long.
