That never occurred to me for some reason. Makes sense. There might be a lot of money to be made. The only thing that makes me wonder is the uncertainty around the regs. Someone who is planning to sell juice after the legal market closes down has to hesitate a little before spending a bunch of money on something that might not happen. I think it would be a pretty safe bet though, and the potential profit margins would be huge.
At a certain level of black market thinking (one I don't even care for), it could very well be these people pushing for harsh regulations. In a sense though, why wouldn't you?
Another aspect is that I think a lot of people may already be doing it. My sources of information are limited, but I've heard a handful of reports from the real world about people buying and selling home made juice, and a few posts on here that suggest the same thing. Does anyone have a handle on how widespread this might be?
We are currently existing in a gray market, from how I understand things. We were never sanctioned by the powers that be to sell vaping items. I believe their preference would be to disallow all sales until it is properly vetted, read as 10 to 30 years of studying. Once that is concluded and risks are better understood, THEN would be the time to allow public access, in way that makes sense (to them, or to humanity).
I honestly think of everything as "home made." But do understand a distinction between product made in low quality production line and high(er) quality production facilities. But to answer your inquiry in way that makes sense to me, currently all product is being home made. And as much as that is debatable, I think it quite plausible that if everything (legal) goes to level of 'big vape production,' then it strikes me as very likely that incidents of harm go up from where they currently are or have been in the gray market. Intuitively, it would make sense for it to go down, and yet the known incidents of harm currently wrt eLiquid is between very low and non existent. The unintended incidents (i.e. child swallowing liquid lying around) aren't going to change because of big vape production.
With an underground market, buyer and seller have very good reason to not report (minor) incidents of harm going forward. Major incidents of harm in that type of market will be exploited, but we already see that in the gray market. The major incidents will be double edged. On the one hand it will be spun why no one should ever vape, but especially why no one should ever vape anything from the illegal market. And on the other hand, it could be spun as why the legal market needs to be far more flexible, with knowledge that prior to the restrictive market, there were far fewer incidents of (major) harm.
With the legal market, that is highly restrictive, I can think of a few reason why incidents of (any) harm will go up. One being that scammer types or ANTZ friendly people will constantly seek to exploit BV and keep them tied up in civil court, hopefully gaining large sums of money. From ANTZ perspective, the sooner a master settlement agreement with BV is arrived at, the better for 'everyone.' At that time, then everyone will understand that vaping was inherently dangerous like ANTZ was telling you back in 2015 (and before). Another reason I think incidents of harm will go up is because of stiff competition and essentially bad players (or scammers) within the playing field then. As in don't use 'their product' cause they have cooties. If anyone favoring legal market politics has any desire to keep it to say 3 to 5 major companies, then one way to ensure that remains status quo is to make it so any competing players are strongly associated with 'harmful products' or lesser quality. Third reason I see incidents of harm going up is that vaping will then be fully accepted as 'legal' or understood as 'FDA approved' while ANTZ continue to churn out information that says 'vaping is inherently dangerous, and here, let us count the ways.' Scammers, as mentioned before will exploit that. But regular joes and janes will think twice about any affliction they are feeling and due to fear mongering from ANTZ will attribute it to vaping. As in, "my throat is scratchy lately, doc says it could be serious throat condition, and I'm thinking it is due to vaping. Saw article recently that said vaping ruins people's throats. Yeah, it's gotta be the vaping, and only vaping that has caused this." Fourth reason I see, that follows from previous one is that when vapers do die, then ANTZ will have ammunition to start running with meme of "vaping kills." If you are someone that currently believes "smoking kills," then I don't think it'll be too hard to convince you that "vaping kills" especially as there will one day be plenty of evidence that vapers die, even while vaping up to their last breath.
Fifth, and final reason that I can think of is that I think product will be altered due to perception that "vaping, as it stands now, is inherently harmful." Here in 2015, pre FDA-deeming, a pro-vaping enthusiasts (rightfully) finds that questionable, or doubtful. But I think if market is restrictive, and ANTZ continues being ANTZ, and scammers are exploiting the system, and all other things I mentioned before, then scientists will insist the product has ingredients that are 'avoidable risks' and that this substitute chemical, while not perhaps well vetted, has got to be better for everyone than the 'known' harm that is currently in vapor. And so, all product must now only contain that. That strikes me as enormous gamble to take. And one that I wish to go on record in 2015 as saying I think will backfire. Big time.
