...[ ]...What it does not say is that the cause is the products that contain THC. It rather explicitly says that they have not identified a common cause in all cases, and perhaps that paragraph is not worded well such that it is easily understood by everyone. Honestly, even with the bad press that the CDC sometimes gets, I trust this information more than any other source.
Any serious proclamation the CDC makes, is subject to more stringent standards, than a jury verdict in a felony trial. The CDC has to have proven their theory, "beyond a shadow of a doubt", before rendering a statement of a causal link between"X" substance, and "Y" disease or malady. Which is why, they're using conditional syntax in their opinion. IMO, it's simply a question of waiting for conclusive and repeatable laboratory results before going public.
This whole issue is most likely being overblown by the media, and today's moral standards whereby, "no one is responsible for their own actions, whatever goes wrong, is someone else's or some corporation's fault.
Today's marijuana is "not your granddad's reefer". As a profit based commodity in a competitive market, it's been bred and refined for maximum THC content. And smoking it is irritating to the lungs.
Granted, that I'm pretty much the "white lab rat", which is bred to be hypersensitive to any toxin or disease, simply by virtue of my age, of having smoked for 40+ years, inhaled pounds of asbestos laden brake lining dust, and all kind of automotive finishing products over the years.
That said, I can have a cigarette with a friend on occasion, with little to no presentation of symptoms. In other words, no coughing and a little bit of a buzz.
Now, today's weed is an entirely different story. I had a couple of pokes the other night, (first time in maybe 35 years out of curiosity) and it left me choking, coughing, and sucking on Hall's cough drops for the better part of two days! In fact, although I don't have asthma, it precipitated an asthma attack, where the harder I tried to breath in, the harder my lungs constricted.
Now, the person I was testing "the new breed of weed" with, was apparently unaffected.
However, I can't help but speculate that if the added THC component of today's pot is responsible for the hyper irritating effects I experienced while smoking it, the same effects might be masked or mitigated in an efliud delivery situation. However, it's fair to speculate that prolonged and excessive use could inflict long term and permanent damage, that more or less "sneaks up on you".
One set of individuals I never attach any value to their media published opinions, are parents. "My boy (or girl), is virtually always 'a good boy', and couldn't have possibly inflicted this injury on himself". The only time I've ever seen parents back off from that stance, is after their child has gunned down a couple dozen of his (or her
(*)) classmates. At which point, they usually apologize for the bad behaviour.. (provisionally of course), and mitigate it by saying, "I don't know what could have gotten into him". In other words, the "near death" boy's lung problems can't possibly be of his own doing by way of abuse or excessive excess.
So, I wish all you e-adicts well, vape your brains out, and whatever happens, remember, it's not your fault, and personal injury shysters are a dime a dozen.
(*) In fairness, I can't recall there ever being a case of a mass shooting by a female. But you still have to include them in the issue, in consideration of political correctness
