If you smoke, you smoke, and you have your reasons for smoking. It's not like you didn't know what they'd do to you, and it's not like you weren't given fair warning about it, yet for your own reasons you decided to do it anyways. People who don't smoke obviously don't share their mindset or motivations.
You can't exactly criticize someone else for being self destructive out of their own choice without being arrogant.
Those "No Smoking" signs are bull, most of them aren't enforced.
Most of those "No Smoking" signs have seating around them, and are sheltered from wind or rain. We're not going to smoke out in the rain. It's not like they're following you around with the cigarette, so just move away from them, or ask them to keep it downwind of you. It's the pollution from industry and cars that's damaging your lungs 24/7 regardless of where you go, not the occasional wiff of second hand smoke on the street. If you're that concerned about your lungs, there's bigger issues you could be tackling which you aren't, so why target us?
Furthermore, we can't throw our butts into the garbage, because that starts garbage fires.
Provide more buttstops on the sidewalks IMO. Until then, there aren't many other places we can put them.
Or better yet, complain and get them outlawed from being sold in stores. I say that being a smoker. Tobacco these days is horrible. Most of the rush you get is thanks to all the cyanide. The tobacco plants they use are of poor quality, and they just use the whole plant, stem and all. Basically meaning that the smoke has less active nicotine for more damaging air impurities. The cyanide basically transports the nicotine to the brain faster, meaning that the rush comes on quicker, more intensively, and fades out sooner, meaning you crave it again quicker, and you crave a faster/more intense rush than nicotine naturally would provide.
Look at cultures who aren't exposed to the same chemical ****tail (lol at censorship) brands of cigarettes, but instead smoke pure tobacco from quality plant leaf. They don't have nearly as much risk of becoming habitual users. Cultures have used tobacco as medicine for centuries without ever facing an addiction epidemic like we have now. I'm not saying tobacco itself isn't addictive, I'm just saying that when you rush the addictive chemical into the brain like that all at once, the impact is multiplied. Anyone who's ever grown their own tobacco has probably realized that it's not the same as smoking a cigarette, and you can still crave a cigarette right after smoking the pure leaf.
Market-quality tobacco should definitely be illegal, and the companies should be held accountable for purposely making their products more damaging and dependency forming than necessary.
Nicotine patches/gums are a joke, they only make sure you stay addicted as you try to quit, and prolong the withdrawal period. Cigarette cravings will not decrease until you've been 100% nicotine free for some time. Putting nicotine into your system will only reinforce the biochemistry that's causing the cravings. Studies have repeatedly shown a significantly higher quit rate in people who use no aids and stop cold turkey. Manufacturers of these products should be held accountable for false (and disproven) advertisement claims leading people to ignorantly keep their addictions alive while they psychologically feel as if they're actually doing something to quit. Patches are just a step backwards.
So, if you smoke, good for you, your body's actually in horrible condition despite how good or athletically fit you may feel, but you already know that. Just take deep breaths as you exercise and remember that you're exhausted because you smoke, and if you're going to smoke, you have to deal with the consequences, so accept responsibility for your actions and use it to motivate you to work that much harder at your exercise until such time as you decide to quit for good. Until that time, anyone who gives you crap is just being self-righteous and hypocritical because I can guarantee, they do things that piss other people off to.
So, that's my 2 cents.
