How much do you see the most addicted smokers smoke in a day?

The true story my dad told me is that my dad often traveled on business when he was young. Once he was on a business trip with a colleague. In a hotel, his colleague was a huge smoker. How old was he? He only needs three matches to smoke every day. After lighting a cigarette in the morning, he will light one cigarette after another. Three matches, one after another... In this way, he can smoke several packs of cigarettes a day with three matches.
