It's not a reason to ban this product. I believe you can still buy an insecticide that is mostly nicotine. Nicotine is part of a plant's defense. Eat it and die.
The cartridges and
e-liquid are more of a danger to children and pets. We ban magnets that children can swallow. Could a child swallow a cartridge? You judge. And small amounts of nicotine could kill a cat or dog. One user said his cat started licking his fingers after he'd gotten them in
e-liquid. If the animal ate a cartridge, no telling how that might turn out.
Be most concerned about whether someone decides e-smoking devices are NRT (nicotine replacement therapy) items. If they're seen as that, they will need years of testing before they can be marketed in the U.S. And they have two extremely mighty enemies: Big Tobacco and Big Pharmaceutical. Right now, Big Pharm funds the anti-tobacco groups and is absolutely gloating on the idea of 46 million American cigarette smokers deciding to kick the habit -- by turning to Big Pharm's gums, patches, lozenges and inhalers.
E-smoking is better than any device Big Pharm offers. See the problem? It will steal
their money. And since it contains no tobacco, Big Tobacco has everything to lose (one e-Liquid maker says it gets its nicotine from potatoes). I don't worry about any poison except that spewed by those who will oppose e-smoking because it will cost them revenue before too long.
