Cigarettes are literally dried up leaves. Their customers light the product on fire and then buy more the next day. Given that as a viable business model, how do you not make ridiculous quantities of money?
They’ve also significantly reduced the materials consumed over the years. Cigarettes went from 8.6mm diameter to 8.5, 8.4, 7.9. Introduced slims 7.1, superslims 5.4. They started expanding the cellular structure of the tobacco with co2 to increase its ‘filling capability’. Longer filters, hollow filter tips. Thinner tipping paper. Thinner paperboard, thinner foil, less glue. The list goes on and on. Lots spent on R&D, but small material savings on billions of cigarettes soon adds up.
You can get roughly 22 packs of cigarettes from a pound of tobacco. Lets say RJ Reynolds sells those packs for 2.50 wholesale. 22 * 2.50 = 55. 10x the cost of a lb of tobacco doesn't seem too bad.
