Not to be rude to anyone who smokes, I just find it very nasty and unhealthy to do so, I just wish people would learn that! Also, It's sad to have a grandparent who used to smoke talk about how he could have given up earlier or should have never done it in the first place, and now he has to breath with an oxygen tank all the time. Personally, I also don't like it because I have asthma.
