A standard carton of cigarettes usually contains 10 packs, and each pack typically has 20 cigarettes. This means a carton generally contains 200 cigarettes in total. However, in some cases, a carton may contain 20 packs, which would amount to 400 cigarettes. The exact number of cigarettes in a carton can vary by country and manufacturer, but the most common configuration is 10 packs of 20 cigarettes each, totaling 200 cigarettes per carton.
