THE REAL COST OF TOBACCO
In lives, in money, and in the world we leave behind

Every year on 31 May, World No Tobacco Day invites us to pause and look honestly at what tobacco actually costs us, not just as individuals, but as a species. The picture that emerges is extraordinary, and not in a good way.
We are so accustomed to seeing cigarettes in the corner shop, or smelling smoke on a high street, that we can become numb to the scale of what the tobacco industry represents. So let me lay out the numbers plainly.
Tobacco is the world's leading cause of preventable death. According to the World Health Organisation, more than 8 million people die from tobacco-related causes every year. To put that in human terms, that is roughly equivalent to the entire population of London dying every single year, year after year, from a product we voluntarily continue to produce and sell.
Of those deaths, over 1.3 million are people who never smoked at all. They are the partners, children, and colleagues of smokers, whose exposure to second-hand smoke is enough to cause serious cardiovascular and respiratory disease, including coronary heart disease and lung cancer.
Tobacco is a risk factor for more than 20 different types or subtypes of cancer, as well as being a leading contributor to cardiovascular disease and chronic respiratory conditions. Tobacco smoke contains over 70 known carcinogens. There is, as the WHO states clearly, no safe level of exposure.
Around 80% of the 1.3 billion tobacco users worldwide live in low- and middle-income countries, where the burden of illness and death falls hardest. These are communities that can least afford it.
The global market for tobacco products was valued at around US$850 billion in 2021 and continues to grow. Yet against that commercial value sits an economic cost more than one and a half times larger: US$1.4 trillion every year in healthcare expenditure and lost productivity, equivalent to 1.8% of the world's entire GDP.
This is the tobacco industry's hidden subsidy, paid not by shareholders or executives, but by patients, families, and health services around the world. In many countries, tobacco companies largely avoid the full burden of taxation while the public purse absorbs the consequences of smoking.
For the poorest households, tobacco spending often exceeds 10% of total family income. That is money diverted away from food, education, and medical care for children. Low- and middle-income countries bear roughly 40% of this global cost despite having far fewer resources to absorb it.
Tobacco's destruction does not begin when a cigarette is lit. The damage starts in the ground, and it is vast.
A WHO report found that the tobacco industry is responsible each year for the loss of 600 million trees, the destruction of 200,000 hectares of land, the consumption of 22 billion tonnes of water, and the release of approximately 84 million tonnes of CO2. Tobacco farming accounts for around 5% of global deforestation, driving soil degradation, ecosystem collapse, and the loss of agricultural land that could otherwise be growing food.
Then there is the waste. Cigarette butts are one of the most common forms of litter found on beaches and in waterways worldwide.
They leach thousands of toxic chemicals into soil and water, harming aquatic life and entering the food chain. Products such as e-cigarettes and vapes add significant quantities of plastic and electronic waste to an already-strained planet
