Random thoughts:
What would happen if a person accidentally got some tobacco in their mouth, where it might inadvertently lodge itself between the cheek and gum? The resulting nicotine juice would be strong enough to kill the poor sap's entire family I'd imagine. Good thing that is a far-fetched scenario that could never possibly happen.
The individual that died from nicotine did so by injecting it his arm. I don't know if people realize what will happen to a person if they inject themselves with AIR (massive fatal heart attack). I think lawmakers need to get regulations in place regarding this hazardous gas that we so innocently expose our children to day in and day out.
At some point in the past children gained exclusive rights over things sweet, fruit-flavored, and brightly colored. If your product fits all three of the criteria, all parental responsibility regarding that product is nullified. There is no logical way a non-child could enjoy such a thing. You are an inherently bad and predatory person for even thinking of such a product let alone selling or owning it.
Where are you from? In the US dipping tobacco is common, available at pretty much every gas station/grocery/convenience store. You put the shredded tobacco in between your lip and gum, the nicotine is absorbed through your skin.
There's also snuff, the actual snuff tobacco, not the "snuff" that is dip. Snuff, aka nasal tobacco, is placed in your nose to let the mucous membrane absorb the nicotine. That's some really cool stuff, I've got a small tin of it in my desk. Love to indulge in actual tobacco but I dipped enough wintergreen that I cannot stand dip anymore, and I quit smoking everything, so snuff is the only whole tobacco product I enjoy. In fact I snuffed a bit yesterday and a bit the day before, after having gone some months without using it.
Anyways yeah pure nicotine is quite deadly, since it can be absorbed through your skin getting a drop or two of pure nic extract could kill you. Juice is mixed so that the actual inhaled amount is relatively low. You'd have to spill really strong juice (mixed juice, not pure nic) on your skin and let it completely absorb first.
Plus, leaving your shit out like that is irresponsible when you have kids or pets. I don't leave my weed stuff out just so my DOG doesn't get too curious, my ecig juices are in a little box on a shelf out of sight and out of mind.
By the way, apparently the only recorded death from nicotine extraction ecig juice stuff was from a guy that committed suicide by injecting nicotine...
