I think it is time.. to bring out the very large green YUCK FACE stickers... too
I have a 2 year old.. if I called my vape (I call my liquid my "vape stuff" ICKY KAKA OUCHIES YUCK for mama only is added when around my son) juice he'd be all into that stuff.... so I agree with OP about it being a horrible idea to refer to vapes as "juice".
My 2 year old LOVES juice and I could see someone referring to their e-liquid as juice and him thinking it was juice and trying to get it and trying a slug of it or more. I really can see that happening. Maybe people whose kids are grown and do not really remember what it's like with a toddler or who have less adventurous "try everything" toddlers vs my "if it looks yummy or sounds yummy I'm going to try to get that stuff" 2 year old..
And at the people who think they will stop because it tastes bad or burns? Not necessarily.. Kids have been known to drink bleach, to drink drano, to drink all sorts of NASTY tasting cleaners and even things like isopropyl alcohol etc. Why do you think there are case-reports of children dying after drinking such stuff? Because kids don't stop at a lick. They guzzle/down/drink things.
My 2 year old drank half a bottle of dawn dish soap because it was pretty and smelled nice, I think .. I don't imagine it tasted very good.. I imagine my vape tastes much better than that.. actually I know it does... and he was 18 months old and I'm pretty sure in his little brain he thought "maybe the next guzzle with taste better.. it smells nice!" .. He was fine, had a little bit of the poops.. yes I called to make sure I didn't need to take him to the ER or anything. But, that blows the whole "if it tastes nasty they'll stop" thing out of the water, at least for my kid.
I vape no-nic liquid and have for quite a while now.. anyway.... but I still keep it out of his reach or locked up cause I don't want him to get into it.
I can see where the OP is coming from very clearly because I know my kid would totally drink something someone was referring to as "juice" and left it in his reach and turned around/walked away/whatever. Or even if they put it up. He might, in his toddler-esque sneakiness (oh, he drags chairs, watches for the front door to be unlocked and darts out it.. he's a clever little ... pooh!), find a way to get it down. The only solution is, if it has poison, lock it up and make it non-enticing.
Child safe caps? HAHA! He can bite them off! Oh yes. He can.
You cannot train a 2 year old (or 3 or 4) to have willpower against a word like "juice". It's like expecting your even EXCELLENTLY trained dog not to eat the pork chop if you leave the room. It's just not going to happen for like 99% of dogs. They're gonna eat the thing. They don't have the brain capability to have self-restraint like that, not without you staring at them, and in many cases even with you staring at them. So, you have to keep it out of their reach/locked up and simulanteously not make it extra enticing (just incase, you say, forget to close your lock-box all the way or have a brain fart and leave the liquid on the counter for a moment as you turn your back. Or they learn how to climb. Or whatever. I mean, parents are human??). I bet you anything if I called my vape "candy/chocolate/juice" my kid .. rather than just ignoring it as another "icky yucky" .. would be actively trying to get into my e-liquid. And he would likely catch me making a mistake if he was actively trying to.
Be real folks. Words do matter with little kids. I would argue that the sweet names are a bad idea to use around them too.
I have never referred to my e-liquid with the candy names or fruit names for that very reason.
It is always just my "smoke" my "vape stuff.. " "icky kaka ouchies yuck".
Of course, I have a really adventurous/determined toddler.

Maybe my views are colored by that. hahaha.
