PREVENTABLE death. It costs everyone money when it shouldn't.
It costs everyone a lot of money? What is this, youre a greedy bastard?
Well, firstly, I would like to point out that you have what could be misinterpreted arrogant attitude. Then what I am going to say probably will please you!
Actually Poland did a research on this subject, and wouldnt you know it, its actually good for the economy! People die earlier, ergo less expenses for treatment the elderly. This actually by a great deal outweighs the negative consequences you mentioned. Another extremely positive factor is the relative high taxes being put on tobacco sales. This depends on the individual countries, but for instance for Norway, which I come from, have put taxes in the range of several hundreds of percent on the tobacco.
Therefore, as a conclusion, there is no economic negative aspect to tobacco. If one is to state a reason for banning tobacco, it would be on a basis of telling people of how they should live their life. Like in a communistic system. Is that ok?
