Tobacco has not only negative effects on health; it also has an environmental impact. Each year, tobacco production requires 22 000 billion liters of water, mainly for cultivation. Thousands hectares of forestland are cleared annually, largely for the desiccation of tobacco leaves. Cigarette production is responsible for 84 million tons of CO2 equivalent. This paper reviews the environmental impact of the production and consumption of cigarettes from tobacco growing and manufacturing to consumption and waste production, and compares it with current consumption data.
