Basically you're arguing for the cancer industry because it makes money. Congrats, I won't go down that low with you. People will get over cigarettes, once an entire generation doesn't have them, they won't be missed. And once weed is legal everywhere, most people will switch over and the tax money will come from that. Again, simple solution to cancer-sticks.
If the hypothetical idea of an afterlife means more to you than the objectively true reality we all share, then you deserve no respect.
