I applaud your consideration... but I see that you still drive. You might be interested in this data...

"The average cigarette contains about 12 mg of carbon monoxide and an equal amount of tar (hydrocarbon-like substance). It also contains about 1.2 mg of nicotine. Nicotine is not a component of internal combustion engine emissions, therefore it is difficult to properly locate in this comparison. However, since it is part of "cigarette emissions" we will be fair, and shall add it to the total, which mounts now to 25.2 mg.
This is the equivalent of:
5.78571428515 [to the 15th power] (57,500 billions) cigarettes each year
7,358,400 cigarettes each U.S. square mile every year (including Alaska & Hawaii)
22 millions cigarettes per person each year
20,160 cigarettes each U.S. square mile every day (including Alaska & Hawaii)
157.5 billions cigarettes each day
60,875 cigarettes per person each day
2,540 cigarettes per person each hour
42.5 cigarettes per person each minute"
Second hand automobile emissions (the type that come from everyone in the WDW Parking Lot) are hitting you with a massive amount of contaminants. Is smoking bad? Probably - but it pales in comparison to the really BIG problems.
For myself? Smoking is a choice... but I'm well aware of the needs & desires of others. Just my belief - but I believe that being courteous and kind to others is the best way to go.... I'll always respect WDW policies, and NEVER smoke in an unauthorized area. At the same time? I'm going to get upset if someone designates separate bathrooms and drinking fountains for smokers. I was hoping that America had actually grown up a bit.
