Not a bad analogy...
I have a continuous ink system for my printer.
Left to the free market however, we
did see various manufacturers making it difficult (or trying to) to prevent the use of non-OEM cartridges in their printers (via hardware/firmware, etc). I don't really have a problem with this - just buy a different printer. But the more regulation, the fewer the options to actually do what YOU want to do.
...
Another thing that comes to mind: In the early days of e-cigs (2008/9ish), we saw the birth of a truly free market in this industry. There were no standards, and companies (AND individual geeks/modders and designers) were contributing all kinds of different elements into the birth of e-cigs/vaping (especially on the hardware side, but juice too). This was a beautiful thing to witness, even though it made it more difficult to evaluate all the options. The result of this innovation led to some consistency naturally evolving over time. Who's NOT using 510 style connections nowadays?
...
As far as the juice... I can buy VG and flavorings and vape 0mg if I want. The ONLY FDA involvement should be that the manufacturers shouldn't be putting poison into those products. This has nothing to do with tobacco.
The same could be said of nicotine. BT and the FDA should have NO involvement in anything else, imo.
I think we can all agree that the nicotine warnings on mods and tanks are ridiculous.
In fact, as a thought experiment, I'm wondering how a false advertising lawsuit against a company would NOT win (IANAL). "Hey I bought this purely mechanical device/tank, but I didn't get any nicotine with it! The company is falsely advertising this product!" I would love to see a court case on this.
Even for food items, you sometimes see a warning that "this product MAY contain peanuts" even if it doesn't, or "This was manufactured in a factory where peanuts might have been present" - but you don't see giant warnings "THIS CONTAINS PEANUTS" on cans of almonds.
It's been a while since I've been in a smoke shop (do they still exist?), but as far as I know, tobacco pipes do not have stickers that say "This product contains nicotine", do they?
