Glad it helped, also when you read those study conclusions, you need to understand that just because something is 'detected' in a sample does not necessarily mean that it is at a level which can cause harm.
Dose makes the poison after-all.
If scientists reported about environmental pollutants we come into contact with everyday in the the same way they do e-cigs, everyone would be walking around in a plastic bubble with massive airfilters attached.
Again the most useful studies are the ones that provide direct comparison with cigarette smoke.
The most knowledgeable in the field of THR conservatively estimate ~90% harm reduction.
Since day one I have been in the camp that they are far healthier than cigarettes but I do believe common sense should dictate that anything you ingest into your body that does not need to be can potentially be dangerous. Whether it be food, liquor or vaping.
Lets put it this way, I am 55 and more so than any 30 year old I HAVE SEEN both the tremendous gains that both my husband and I got when we gave up smoking. Beyond the obvious of better lung capacity, healthier heart, we also had numerous small medical annoyances we could not get rid of, suddenly vanish from our bodies.
One for example, we both wore sheepskin slippers and at times boots like UGGs.
We both developed a toenail infection underneath the nail which is very prevalent in athletes, but growing so in the population of those like us that wear sheepskin slippers.
Your feet become too hot, it can breed a fungus that may never hurt you but get an in-grown toenail or some other means of entry around your toe nails and it can enter.
They become almost next to impossible to get rid of as your body adapts and does not fight the infection.
Most people let it go and their nails become pretty grotesque.
We spent a lot of money on $80 nail polishes you have to apply to the nail, sterilizing shoe trees you place into your shoe after wearing them, Lysol spray to spray into the shoes to kill any potential fungus and so on so our nails looked fine BUT it was a lot of work and money to keep them that way and very disheartening for every time it finally has almost grown out and you think you have finally beaten it, you are reinfected.
This went on for 3 years and no one could offer us any hope of ridding us of it.
We stopped smoking and it cleared up on both of us without any real effort.
My husband hadn't been healing easily when he cut himself. All would appear fine but he noticed he was taking 2-3x longer to heel than 10 years earlier.
As soon as we quit smoking, he healed normally once again.
So a few little medical annoyances we could not shake..
20-30 year olds for the most part won't have yet developed such problems.
But knowing all of that?
If I had a child, a teenager that never smoked and came home to tell me they were now Vaping, I would be somewhat angry and would do whatever I could do to put an end to it.
I would not want to see someone that had never smoked take this up for the simple reason that they are then digesting something that they have no need for so why take any chances?
If we are to be hard on scientists, lobbyists that devise studies to "prove" e-cigarettes are bad for us, then we need to be just as diligent, IF not more towards those creating falsehoods in our direction for any negatives for we will not be taken seriously and we cant afford to be wrong not even once!
