I want to smoke wherever it doesn't bother anyone, so mind all you like
The problem is you can't be sure that you won't bother anyone. And there are plenty of smokers who don't care even if they know they are bothering others.
1. The location may be empty for the moment, but there may be other people later on, and if the location has at least two sections of walls, the poisonous gases are going to be trapped there for while, and people coming in later suffers even long after you've left.
2. Cigarette buds left burning. Plenty of those who left it burning on the ground; and those who care enough to use ash trays on top of trash cans but still left it burning.
3. Wind. Wind carries the poisonous gases to places you cannot imagine.
I live in high-rise apartments in Hongkong, and plenty of people smoke. They do understand smoking is bad - they don't smoke in their own apartments. So they smoke in corridors. They smoke in the elevators. They smoke in their balconies and blew the toxic gases out -- which the wind carries right into another apartment. Many times I was woken up in my room, the air filled with the stench of cigarettes. Peering out of the window and sure enough I saw a hand hanging outside the adjacent apartment, holding a cigarette. After a few times I had enough - on a weekday night, 0130am, my room was filled with the stench again and I confronted them. I went knocking on his door, and he didn't even dare to answer the door himself. I told his wife, politely, that his smoking was bothering me a great deal for too many times.
She promised her husband would stop smoking - and later explained that he was not feeling well that day and wanted to smoke one stick (yeah, right). Within a week he smoked at the balcony again, and I yelled at him through the window. He immediately ducked back inside, and then sprayed some cheap perfume out (yeah, right, like that would help getting rid of the toxins).
Next time he smokes I won't be so polite.
I am a victim of second-handed smoke. I had asthma as a kid, no thanks to my dad's smoking. If I ran, I couldn't breathe. If I cry, I couldn't breathe. I kept asthma spray with me constantly for many years. In the end my dad quit it for me, and I got better now. No more asthma attacks, but still not as good as they should be.
That explains the hate I have towards smokers. They are assholes. They know it's bad and they still do it. They know it's bad so they won't do it in front of their families - they just dump it outside to poison someone else. And such a selfish and offensive act is not illegal. Intense hatred fills my heart when I see people holding a baby in one arm, smoking with the free hand. And that's not an uncommon sight.
The legality of cigarette makes it all the worse. Makes people think it's okay to smoke, and one generation of smokers breed another generation. Cigarettes don't deserve to be treated as anything more than drugs like cocaine or morphine, and without a medical use.
