I will answer my research and my reactions.
Those who claim that vaping is safe might very well be protecting financial interests of their own:
One argument I often read about those pointing to the potential dangers of vaping is that they are protecting interest of big tobacco or pharmaceutical (patches, gums, etc) companies. That may very well be true but let's not forget that although the vaping industry represent only a small fraction of revenues compared to the 2 mentioned above, the vaping industry is still cashing billions and that amount is growing exponentially (estimates vary from 100% to 400% yearly growth). Are we forgetting that those who claim so loudly that vaping is so much safer than smoking might very well be protecting their own financial interests?
There is potential dangers for these companies in general just to open the doors. With the FDA warnings, Govornment taxing, and many other potential problems that could simply shut someone's whole operation down, the fact they have a markup is no surprise. Someone invests money into opening up any sort of shop, and in 3 months, some regulation could shut their entire investment down. Those who shout the loudest usually aren't the shops themselves, nor the vapers. Most of the proposed regulations stem from LACK of knowlege. they are trying to shut down the industries where the current research is that it is SAFER. I'll get into that in a moment, but the loudest people aren't the vape shops, aren't the vapers, but congressmen and diplomats who find the whole vaping scene as a threat to THEIR financial gains. That is why you find regulations wanting to tax it up to being as or more expensive than using regular cigarettes, so people won't want to switch from their current trend and taxes.
The fact that most or all ingredients found in e-liquids are considered safe to eat doesn't mean that they're safe to vape:
First there's the fact that ingesting PG or VG or any of the thousands of chemicals contained in flavoring and/or coloring with food or medication is NOT the same as ingesting them through vapor. As we all know heating something sometimes modifies its chemical structure, can create chemical interactions and/or modifications of the components involved. In other words it's not because it's safe to eat something that it's safe to inhale the same thing that has been submitted to extreme heat and vaporized.
And then of course there's the question of pure quantity. My wife is asthmatic and inhales (non heated) PG with her medication. But let's face it, quantities involved are hugely different. I vape more or less 10ml/day. Can I assume that because the few micro mls of PG contained in asthma medication have been deemed safe I can with impunity ingest million of times that quantity when vaping?
Propylene Glycol has been around for over 50 years. It has several uses and should not be regarded as simply an E-Cigarette chemical. One of it's uses, is as a fog machine. There ARE some cases where fog machines are used in theatrical stages, houses of horror, or parties. There are employees that work in those places, and have worked there for quite a while. Propylene glycol has also been used in the medical field as a drug carrier in an inhaler. These are not new inventions and have been out for many years. There hasn't been any long term exposure detriments to inhaling propylene glycol or Vegetable Glycerine in the last 50 years besides minor cases..things we're quite aware of and people have been warned against.. allergies, drying of throat, etc.
And then there is the fact that amongst some of the thousand of chemicals involved in the composition of e-liquids a few ARE extremely dangerous:
If you're vaping and find my post ridiculous, please at least read this thread: XXX.e-cigarette-forum.com/forum/diy-e-liquid/534508-flavors-may-contain-diacetyl-there-really-many.html (Flavors that may contain Diacetyl, are there really this many?) Forgive the XXX but I'm not allowed to post links. Please replace with www
Diacetyl is found in several food products. Chances are, you consume it every day in many products. Again, going with the "it is not inhaled" aspect, It has not been a banned substance, and the only major concern has been in a factory that heavily uses it. Even after that case, they have not banned it. ANYTHING taken in excess can be harmful, and trace ammounts in an Ecig does not produce enough to warrant much concern.
Long term research is non-existent:
We do have a few researches about short term effects of vaping and they do seem to indicate, for most of them at least, that vaping is much safer than smoking. But of course we have absolutely no long term researches due to the simple fact that vaping hasn't been around for that long. In other words, me and other vapers are guinea pigs and our cadavers, when we die, are hopefully going to provide data for future generations of vapers.
I have mentioned earlier, Even though putting nicotine in propylene glycol and Vegetable Glycerine is a new way of getting nicotine, People HAVE been Inhaling these substances for many years and for long periods of time. There has been no medical reports to indicate there should be any concern. How many employees dressed as a fearsome monster in a foggy haunted house have indicated any problems, how about how many lawsuits were submitted due to their inhilation of Propylene glycol to get their asthma medicine, or how many DJ's are admitted to hospitals for inhalation of excessive smoke juice from their clubs.... It's all been out for a while, it's all been used.
Does it mean we should panic and stop vaping?
Of course that's for each of us to decide. Personally, I consider that if we think that we are daily ingesting GMO's, breathing polluted air, eating transformed food containing millions of chemicals, vaping is probably not much worse than all that stuff.
But blindly believing that vaping is safe and that as ex-smokers, we can have our cake and eat it too is a bit unrealistic.
And also let's try to keep in mind that those defending vaping so loudly may have strong financial motivations to do so. Pointing the finger at tobacco and pharmaceutical companies doesn't necessarily mean that you don't have financial interests of your own to protect.
I am a vaper, the only financial interest I have, is how much MORE I will have to spend on vaping gear due to unwarranted concerns. People see it look like something that is KNOWN as killing, and they look down on it. There is always something wrong with SOMETHING you are using now. We clad ourselfs in a virtual suit of chemicals every day without thought. as far as I am concerned, switching from regular analogs is many times safer than something that has killed both my grandfathers and step father. The delivery of nicotine by regular cigarettes is a flawed design, and it's not the thousands of chemicals in them that kills people, it's the delivery METHOD that kills. Burning substances and inhaling the remenants are what kills millions of people. That's not taking into account ANY of the chemicals inhaled. Cigarettes have more chemicals than an Ecigarette, that is a known fact. so, if you can eliminate the burning component, and elminate the inhilation of 1000 chemicals, then the option is a no brainer. Why tax me or be concerned about something that is so blatantly safer?
