Public includes non-smokers too! I don't NEED to smoke, I don't WANT to have health problems and die prematurely because you NEED to smoke! More than that, I don't want my children and grandchildren to do so. Would it be fine with you if someone were to sit next to you in a Public enclosed space and proceed for the next several minutes,to spray a mixture of benzene, nicotine, formaldehyde and the thousands of other poisons found in secondhand cigarette smoke, oh...I forgot, let's mix a hefty dose of carbon monoxide in there, you know the same poisonous gas that we protect ourselves from in our homes and garages because it can kill us. How about if this person works in the same space as you all day and NEEDS to spray this mess around at least 20 times a day. You know, they are a pack of day sprayers! So, you are right, you have the right kill yourself in peace but you do not have the right to kill anyone else.
