I believe smoking should be limited to certain areas. Neither banned nor allowed. People who chose not to smoke shouldn't be subjected to the second hand effects.
However; I smoke, and though I would encourage most non-smokers to take into consideration that smoking is like many other dangerous-self destructive drugs, I also encourage those people to continue the fight to stop smoking all together.
I am at a point in my life where I have recognized that my entire day revolves around my next cigarette, my mood is fully developed upon if I have a suitable amount of nicotine in my body... it's sad, disheartening, and I regret ever picking up the first one.
In a nutshell, to the programs broadcasting commercials with former smokers who now have to live with trachea's, to the anti-smokers who consistently nag, to the activist who harass the cigarette companies, and the quickly growing population of people who show disgust and concern for smoking... I THANK YOU... YOU my friends will be the reason for a reformation, will save numerous lives, and let all smokers suffering from the addictive, life consuming plant know- we can do it, and we will do it- with the support of an entire nation... world even. Either blunt, "rude", or passive- the message is very clear and very constructive. Thank you.
