There are many "bad" things for us to do and we engage in them every day. Some we do by choice (think alcohol) and some the government and corporations foist upon us (think genetically modified crops) and make it difficult for us to choose not to engage. I prefer to indulge in my vices in a manner that doesn't affect the health of others. So, for instance, I don't smoke my little cigars inside. But, if I can enjoy one outside while drinking a cup of coffee or a beer I have no problem doing that.
