I believe vaping is ok for some people but they never seem to give that up so they are still addicted just in [perhaps] a less harmful way. If you want to give up smoking there is only one way...and that is to stop, just stop. Vaping, cutting down, only smoking after ten am or only on days with a 'Y' in it, none of these things work, you are just prolonging the agony and fooling yourself. You are still addicted.
One of the interesting things about the rise of vaping is that it's given various scientist a vast pool of volunteers with which to test these long-held assumptions - and one of the very first questions asked was "If nicotine's so addicitive, how come so many vapers are consuming a fraction of the quantity they were before...with no apparent ill-effects?"
Granted, initially there seems to be a need for a high level - but it ramps down extraordinarily quickly...far more than it ought to given the 'pernicious' nature of nicotine addiction.
Vapers too started asking questions - the most common being "How come this is so easy?"
It turns out that most of what we 'know' about nicotine comes from some pretty dubious sources, and a very great deal of doesn't stand up to even very basic scrutiny.
Thankfully there's new research being done - and old research is being re-examined with a more critical eye.
One of the most entertaining snippets is that the LD50 (the toxicity of nicotine) we've been using for the last 100 years turns out to have been completely made up by a couple of scientists who made a complete bodge-up of their experiments. No-one queried it for 100 years, and now it seems it's 10-20 times less toxic than we thought.
Current epidemiology places nicotine consumption (via means other than smoking) at around the same risk level as a caffiene habit, and there's some fascinating research that suggests a very credible link to the prevention of dementia and Alzheimers.
But by far the biggest problem with vaping turns out to be that Big Pharma, Big Government and Big Tobacco aren't making as much money out of it as they did smoking.
