I don't think there's really a fair way to do that. From a strictly monetary standpoint, smokers die many years earlier than non smokers. They also often live past the prime of their working life so those lost years equate to a tremendous amount of money saved in reduced payouts for social security, medicare, pensions, etc.

Even if we could assign a strict dollar amount to the long term cost of a pack of cigarettes I don't think that would be a useful thing to do. The cost to society does not factor in the cost to the consumer and while I'm normally pretty libertarian about such things we're talking about a very addictive drug here.
