Is it safe? That's highly debatable. Do the vast majority of us eat it, no questions asked?
Yes.
Logically, everything is lethal poison. Nothing is safe. Only the dosage is up for debate.
However, in matters where there is a question about precisely what poison, and how much, Personally, I prefer known quantities.
Statistically, it is a virtual certainty, that some North American food products contain substances they should not, and other substances in amounts differing from the description. It happens.
It is a numbers game. The fastest horse does not always win the race. Logically though, that is how the betting goes.
I don't own a gas chromatograph, or mass spectrometer. And Bobx's are still in the shop.
My point, is that through knowledge, risk can be managed. In order to do so, one must first identify and quantify precisely what substances are actually being dealt with in order to manage risk.
To me at least provenance has a value. I use the word here with the connotation meaning the original, bona fide source,and chronology of the ownership For a large part of my life, risk management was a primary core objective. The decisions I made each day, could have a potential impact on hundreds of lives. And I use the word impact in the literal sense here.
Some of those lives were able to make informed decisions to a greater, or lesser extent to trust my judgement, Not too big a leap of faith for them because after all, their asses were only a tiny fraction of a second behind mine. Many more people went about their daily lives blissfully unaware that I was flying overhead.
In flight school, and my brief studies in aerodynamics, I was taught that officially, physics are what make airplanes fly. Bernoulli, Newton etc. That is the official explanation. Personally, I've always known it is sorcery. Practitioners of the art perform rituals, walking around the ship in the prescribed manner, pushing on this, pulling on that and peering at the other thing, then, through strange incantations, and recitations of lists, the arrangement of numerous mystical objects in carefully prescribed positions, and after conversing with unseen deitys in high places, more spells and incantations, there is the moment when lift equals weight, thrust equals drag, and you feel the wings start to take the weight from the wheels, and at that moment, all those thousands of them, I never once experienced any doubt that something less than magic was at work.
The truth though, is that aircraft fly neither because of physics, nor magic (well, perhaps a little of each) primarily, they fly on trust. Every component has a recorded provenance. Every system, every sub component can be tracked from its creation to the present moment. One trusts that they were engineered and designed and tested and manufactured and tested again, and maintained and tested more still.
We are taught to trust our instruments. However, if one trusts a control, navigation, engine management, or communication system which has a counterfeit surface mounted integrated circuit, manufactured in China, marked in a identical manner to the authentic certified part, it will probably be just fine. The chain of fictitious PRC registered companies whose existence and only purpose is to obscure the actual origin of these components is no mere accident, it is a national industry, coordinated by a corrupt government, to whom the dollar outweighs your safety. The definition of probable being 51% or greater. (BTW, random, is often described as a coin toss, with the outcome being 50/50, with a variance of +/- 5%) It will probably test the same as the authentic, and perform the same, at least that is, at sea level, with no vibration, at room temperature.
Not all Efest batterys are deliberately over rated, not all will go into thermal overload, explode, and propel an atomizer through your palate into your sinus cavity, fracturing your cervical vertebra in the process. Most are just factory seconds of dubious origin, re-wrapped with outlandish specifications. Probably, they will be safe to vape. Probably.
Now, we are seeing counterfeit Efest batterys. Counterfeits of counterfeits. Can you guess where they are manufactured? Here is a hint. Not in Switzerland.
Of course, given a long enough timeline, the survival rate of anything equals zero. I have some recent experience in this, I should know. I won't ruin the surprise, but for me at least, there was no welcoming, warm white light. FWIW, I advise avoiding death for as long as possible. I advise that if one is going to do something that may be dangerous, (and what isn't) that one should at least know to a reasonable degree the composition of the involved materials, in order to make an informed decision.
Not sure I understand your logic.
I hope you better understand it now. I respect your personal choice to put whatever substances you choose into your body. Even if it were cigarettes. I do not have a double standard. In the same manner, I'm sure you respect my decision to inform, and advise others about ingesting substances of dubious provenance. More so if they are just beginning on their journey in this particular art. While I might understand and respect the right to choose to smoke cigarettes, I won't recommend them to others. Unless they happen to be my mailman.
