Exactly. If I eat nothing but McDonald's all day I'm only hurting myself, but if I smoke or vape I'm hurting everyone within 50 feet of me when I do so. It's a disgusting, but more importantly, extremely selfish habit. I have asthma and it was really bad when I was a kid and all of my extended family smoked. They were too addicted to quit smoking around me so I just quit visiting and surprise, surprise, I got remarkably better over time.
