I never thought or heard that any cigarettes were safer than others. I'd say just quit all together. The chemicals are the harmful part of the cigarette and all cigarettes contain those chemicals.
I think some are more toxic than others especially the counterfeit ones that are not regulated. Anyways cigarettes are all harmful and none is really safe for smoking so it is best to quit all together.
That won't help since they are manufactured from tobacco. Tobacco has nicotine no matter switching to different brands. You have to completely stop smoking if you want to be on the safe side. Try to reduce the number of cigarettes you smoke daily, that is when you can get through.
I don't think that there is a safer cigarette brand in existence. Well, if there is, I've yet to see it. A friend of mine who is trying to quit switched to E-cigarettes. It is said that it is LESS harmful than the real ones.
Unfortunately there aren't any safe cigarettes. There was a fallacy spread that light cigarettes weren't as harmful to you as regular cigarettes, the truth is that the smoke generated by lighter cigarettes reaches further down into your lungs then regular cigarette smoke does. The main problem with cigarettes is not only the nicotine, but the thousands of other compounds that make up a cigarette, some even more addictive then nicotine.
