Perhaps its just me, but every time I hear something like 'x causes cancer' my scientific self wishes it was phrased as 'x is correlated to risk of cancer.'
To say 'x causes cancer' implies if you do x, you will get cancer. Thus, everyone reading this sentence, who has smoked, will inevitably get cancer. As we all know that is not true, then it seems far fetched to say smoking causes cancer. Which I think relates to what OP is getting at. But, I realize, that if every vaper in the world went on record as saying smoking doesn't cause cancer, but does appear to have high correlation to risk of getting cancer, that ANTZ would cut out everything from "but" and on and make us look like deniers of a 'known scientific fact.'
With that said, I completely believe a report will come out some day that says vaping causes cancer, because as this post by DougW1971 notes, "everything will kill you." And even if it isn't 'vaping causes cancer' it'll be something else within the ingredients that once a vaper, or handful of vapers, have passed away, it'll be something in eliquid that is correlated with that person's death. Vapers will play the deny game while ANTZ will sound the trumpets of warning for all to pay attention to the notion that if you vape, you will die.
In another recent thread here on ECF (that is now closed) it was suggested that saying just because certain chemicals in vaping are used in other substances, doesn't make it right to note that data. Or put another way, as was stated in that thread, it is contributing to misleading information. Like arsenic in the above list. One might think it would be hard for a smoker to defend decision to smoke if a poison like arsenic is something they are knowingly putting in their body. Yet google "arsenic and chicken meat" and be prepared to realize that if you've had chicken anytime in the last oh say 50 years, you've been putting arsenic into your body. Think this will cause people to stop eating chicken meat? Or lead to bans on chicken meat? Yeah, me neither.
Quotes like this one and a whole bunch of others (on this forum and elsewhere) almost always leave me questioning a few things, or at the very least do a double take. My ongoing wish is for vaping to stand on its own without having to compare it to smoking in order to make vaping seem healthy (or healthier). But I reckon I could live another 50 years and that wish will still remain unfulfilled, especially as some vapers become ex-smokers and then appear a lot like ANTZ in relation to smoking.
One question I have though is if smoking is so darn lethal, and made that way by BT, then how the heck are some of you who smoked 2 PAD's for 40 years still alive? Furthermore, if you are no longer smoking, but still vaping nicotine say for your 2nd year straight, and feel 'very healthy' then either 40 years of very heavy smoking isn't all that lethal, or you are incredibly, super duper lucky.
Bottom line for me on this post is I do actually agree with where OP is coming from in this thread. I think OP, myself and most, if not all readers of this thread, are on the same general page when it comes to vaping - do it because it is a cool, enjoyable, rather harmless way to feed a desire for nicotine. But in doing it and then constantly comparing it to smoking, it would be nice if statements, or so called facts, were comparing apples to apples, rather than making claims that look a lot like how ANTZ talks about smoking. Not only would it be nice, it would be intellectually honest.
