According to research by Picodi, a pack of 20 cigarettes costs almost €22 in Australia, €5 in Portugal and €0.82 in Nigeria.

Data from a study by the medical journal The Lancet, with data for 2019, also shows that New Zealand (21 euros), Ireland (14 euros) and Canada (10 euros) are also among the countries where cigarettes are more expensive.

According to Picodi, in Portugal, a smoker who consumes a pack a day will spend €1,825 on cigarettes in a year, which is equivalent to 18 percent of the country's annual average net income. The Swiss, for example, spend more than the Portuguese (€2,891) on tobacco, but the percentage that this cost represents in annual income is much lower: only 4 percent.

“Smoking in Jamaica (38%), Dominican Republic (41%) and Uganda (44%) consumes the majority of income,” the publication writes. If in Uganda the cost of tobacco throughout the year (701 euros) weighs on income (44%), in Luxembourg the cost is much higher (1,942 euros) but the cost is much lower (4%).
