The tobacco industry comprises those persons and companies engaged in the growth, preparation for sale, shipment, advertisement, and distribution of tobacco and tobacco-related products. It is a global industry; tobacco can grow in any warm, moist environment, which means it is farmed on all continents except Antarctica.

Tobacco is a commodity product similar in economic terms to foodstuffs in that the price is set by the fact that crop yields vary depending on local weather conditions. The price varies by specific species grown, the total quantity on the market ready for sale, the area where it was grown, the health of the plants, and other characteristics individual to product quality. Laws around the world now often have some restrictions on smoking but, still 5.5 trillion cigarettes are smoked each year. Taxes are often imposed heavily on tobacco.
