I would like to ask the Minister how he's going to calculate what revenue he needs? I asked this question to the previous Minister of Finance a few years ago and he found out that his staff were in fact more clever than he thought they were. My question is, are you going to be able to judge the impact of this change on smokers because the assumption is that it will be reduced? In other words, once you tax something, then smoking will be reduced and therefore, you have to use some factor to decide how much money you're going to raise. How are you going to figure out how much money you're going to raise if you don't know what the impact of this tax increase will have to reduce the number of people who smoke?
