Which is why I posted that, as I am sure you know. The thread is thick with conspiracy theories as well as people taking the TL;DR approach and failing to get to the key words - the cause has not been determined.
Well, people here tend to have problems separating their personal experience and opinions with actual facts. I will say that quadruple naught 7's posts are pointlessly long, bordering on diarrhea of the mouth. If there were any other point to then, other than the fact he's a hopelessly addicted vaper, with an obsessive need to inflict his opinion at great length on everyone he comes close to being in contact with. Along with a one track mind, fixated on vaping to boot. Which is the point where I run up against the TL,DR wall, and I believe justifiably so.
Dickens and his contemporaries were, (I believe), paid by the word, which excuses them to some extent for their excesses.
You'll run into the same phenomenon with many newspaper articles as well. The first half dozen paragraphs contain all the necessary information, after that, they're just milking it.
Or simply reading that in SOME cases, vapers have reported using black market vape liquids and jumping directly to the conclusion that black market vape liquids ARE the cause.
I'd have to say that if you're not vaping to protect yourself from the dangers of smoking, then "sport vaping" involving illegal substances would most likely carry a higher risk factor.
My pet theories involve personal high risk excessive use and drug abuse. When you come right down to it, you can vape or smoke marijuana, hashish, and black tar opium.
But reasonably speaking, I imagine one individual could have a "half pack a day vaping jones", while another might routinely vape, "four packs a day"
I think its amazing that some have no clue what "SOME" means and have no clue what "the cause has not been determined" means. But this is TS - par for the course.
China, (according to our DEA, if you choose to believe them),, has an involvement with producing carfentanil, and I believe I read a piece which they were responsible for supplying vaping fluid. Now, China has a poor product safety record at best.and I'd like to mention our huge pet food recall. Ironically, all the supposedly "luxury brands", were made in China, while lowly Purina offerings were home grown. I'm pretty sure China is not above, "stirring our opiod crisis pot".
Put it this way, I certainly don't think China is above tampering with, or simply not bothering what the hell they put in it their product, while we certainly don't have on site FDA inspectors there, as we would in a US food plant
So, those are simply a possibilities, not any iron clad conclusions
It seems that you and I are among the few that have a command of the English language and possess an acute ability to recognize BS.
The tragic thing here a Techspot, is that we've lost many of our more educated and articulated members, while suffering an inordinately large influx of SJWs, gamer boys, and millennials whom have absorbed so much contemporary propaganda, they're incapable of independent thought.
I offer the crap regurgitated from Musk's mouth which metamorphoses to the word of god in topical discussions as a prime example. (Although his company's boards of directors seem to have his leash yanked pretty tight ATM). Although I'm also pretty sure, "this too, shall pass".
