Smoking costs a lot more than it contributes, the head line figure of 2billion cost v 8 billion contribution is just the quantifiable direct cost. Smoking costs far more than it contributes if you include all the indirect costs, eg disabled Children being born and needing care all their lives, fires started through smoking, cleaning up the filth, etc etc I could go on. To answer the question, no one would like an increase of course but I don't think it would happen. Initially there would be a taxation short fall but we would soon be ahead of the game. Income tax only contributes a small amount of the total tax revenue anyway so I guess if a rise is needed it would go on indirect things anyway.
