'"...and preventing vape shops on demonstrating how to use the devices..."
If the article got that fact right, then Ontario got it all a**backwards. If someone blows his/her face away, they've got the perfect excuses:
'Ididn't know, I wasn't told'...
In another thread, we're discussing regulation....
Good regulation would be: Customer walks in, customer gets carded. Customer buys something. Customer gets a demonstration on to how to use/re-fill/re-wick/etc. whatever s/he bought. Regardless of whether it's a simple disposable or a super-duper high-end atty with more parts than a jet engine... Customer signs a paper that instruction/demonstration/information about associated risks was received and understood.
It will not prevent some peeps from tinkering with it and it will not prevent a very few peeps from involuntarily rearranging their facial features. But it will prevent them from trying to blame someonee else for their own stupidity.
Reminds me of these little decals on the back of many electrical items 'No user-serviceable parts inside. Removal of back panel will void warranty and can cause injuries/death'
Clear message. Clear consequences.
The smart ones even put some fancy colored glue on the screws holding the back panel in place
Heck, if I plan on spending money on somethinge more complicated than toaster, I EXPECT the salesperson to be knowledgeable about it and show me how to use it.
