You missed two major points. All of these are meant to be short term solutions to cure a long term health risk. None of them are meant to be used for long periods of time.
Tell that to a smoker who doesnt have the strength or will power to quit and has been brainwashed into thinking that one of these alternative methods can take the place of smoking thinking the side effects will be less. And in the case of the e-cigg, that doesnt have FDA restrictions in the U.S, you have, for a smoker, an avenue that could be used to replace smoking and is just as bad for if not worse short term then actually smoking tobacco considering when you inhale on an e-cigg, you have no clue specificly just how much nicotine you are putting into your body and god knows what else is on those nicotine cartridges. You need a script for the gum, its regulated, you can also die if you accidently light up after using it, and its been known to happen.
You are putting your life into your own hands messing with alternative methoids to quitting smoking. Instead of actually trying the safe route and just stopping and using the method of diet and exercise. Hey better yet, dont even start with such a filthy habit in the first place and all of this is moot.
The risk of these methods if they work far outweigh the dangers of continued smoking.
Speculation at best considering nobody has any clue how such methods will interact with somebodies body. With an E-cigg, you dont know when or if that battery isnt leaking the day you buy it, nor do you know if taking Chantix is gonna make you launch yourself out of a high story window until you actually consume it. Quitting smoking is similar to a snake oil sales man considering you are rolling the dice with your life and pretty much have nobody to blame if it doesnt work out.
Moderation - a glass of wine also has health benefits.
Still on the moderated drinking? It still murders your liver, in moderation or not. Scientific studies about the benefits of drinking red wine, two 4oz glasses within a 24 hour period, still 3 ounces more then putting your liver at risk yet decreasing the amount doesnt give you the
other rewards of red wine. So, you either have ;
A) a chance of turning your liver into a makeshift brick by moderately drinking away yet lowering your chance of heart disease and stroke.
or
b) Getting all the good things red wine does for your body yet ignoring that it still messes with your liver, like putting alcohol into your body isnt something thats just as dangerous as smoking or anyhting.
As you can see, a and b are pretty much the same answer, just reworded. Looking only one way while failing to understand what alcohol actually does to ones body, consumed in moderation or like a flaming drunkard, doesnt change the fact its still, you know, bad for you in the first place, even if they tell you theres so much good from red wine, it still is bad for you, sad but true, and I mean really, its as logical as fire is hot and ice is cold.
What works for one person is not right for everyone. Discounting various methods because you didn't attempt them is short sighted.
Slowly killing yourself in the first place is short sighted. If you dont have that much respect for yourself to put something into your body that will kill you, and has warning on their container that they do indeed kill you yet still go and light up, you have nobody to blame but yourself when and if alternative methods to try and quit dont work. And if its coming off as confrontational I am sorry, smoking is disgusting and in this day and age of knowledge anybody who wants to smoke and pretty much kill themselves slowly deserve to understand the facts that quitting such a filthy habit is on par with a junkie quitting heroin, which in turn makes them a junkie to tobacco.
Dont put yourself in a position where you are a slave to something. Dont start and if you want to quit, use what little inner strentgh you have a quit cold turkey. It can be done and is much better for your health then some silly alternative method/ cop out.
