As far as vaping goes, the same age (18) applies to buying equipment, and juice.
However as far as I know there is no legal age for vaping whatsoever.
With this minefield, of from my opinion ill defined confusing regulations, I am glad that my daughter turned 16 in the latter part of last year.
She does have a vaper, but I am in charge of juice, and it is only 0mg.
I "think" or am pretty sure you have to be 18 to vape in public
what you get up to or allow in your own home is another matter
(though there might be limits regarding child welfare/protection - extreme example giving an infant a fag/vape)
regarding purchasing stuff.....
There are "possible" loopholes in this legislation....
Not saying same rules applies but I'll use a BB Gun or Airsoft gun as an example
in about 2007 new legislation was introduced to satisfy do-gooder MP's concerned over Imitation Firearms etc....
Unless you can provide a valid "defense" - recognised airsofter, or valid reason you can not buy a black toy M4 BB Gun
You can buy a two-tone - painted M4 AK that is easily recognised as a toy/fake gun & not a firearm etc....
PROVIDED YOU ARE OVER 18 (like vaping)
To buy a realistic (RIF) and not an immitation/toy (IF) firearm as classified by the 2007 VCRA act
you need a "defense" of some description for UK purchases (exludes ROI of course)
Now an adult can buy a 2-tone IF or a realistic gun RIF and GIFT it to their kid for example - 101% legit
yup little Jimmy can actually own a black M4 BB gun that was gifted by an adult (with defense)
or a 2-tone IF gun bought by parent/adult on their behalf - no law is broken
Also if you own an old black M4 before 2007 VCRA came into force you can keep/gift it to whoever you like
Golden rule regarding VCRA & u18's....
You can GIFT a BB gun to u18's BUT you can NOT SELL/TRADE one to u18's
It HAS to be a GIFT - no money/items changing hands
ergo - if there is a loophole with vaping like BB guns then it will likely be GIFTING only
If anybody sells a prohibited item to a person under age then that seller is breaking the law
(including an adult or a child selling on a prohibited item to another u18 or no defense etc...)
Yeah - there are certain loopholes in some instances but tread carefully or you could be liable
Not saying for 101% certain that an adult can legally buy and "gift" vape stuff to u18
(as to vape in public you have to be 18, though in your own home anything goes (almost))
but giving an example of certain cases that confuses matters more
As said, in your own home the law may not apply to the letter so much
BUT in certain extreme cases there might be a welfare matter of the child to take into consideration
For the record I'm not judging anybody or parent
I would prefer my 16 year old to take up vaping than smoking or other shit
but ideally not take up any crap until they are legal age if possible
I'm not judging you at all (honest), think I would consider it also if the situation arose tbh
