The amount of damage that cigarette smoking causes is enormous and it's a huge burden on our medical industry and a huge cost to all of us. There is no doubt that antibiotics and pesticides in foods are also a huge problem and I don't think we need to chose between eradicating one or the other. There are huge corporate interests behind both that make it difficult to eradicate. Smoking is horrible for people though add to this the fact that the manufacturers directly market to young people, literally giving away their products to get people hooked and it gets even more despicable. It's the number one cause of preventable disease in the world. Number one. We spend billions of dollars in the US alone treating preventable diseases that are associated with smoking. I enjoy an occasional cigarette, I really do but smoking as a habit is horrendous for the individual and for society. I'd gladly see a world where they didn't exist at all.
