As with most things it's the media and hype that cause all these problems. Our government have come under pressure to do something and as always they are being blinded by false data.From what I've heard, legal importers brought in illegal disposables of stronger nic strength, and distributed them to the chains, nothing can be said other than that they are hellishly stupid.
The only way to stop this is regular inspections of the shops. Those who are serious certainly want shop inspections so they can get rid of those who sell illegal goods and to the children.
Of course, incompetent politicians take the youth trick, it always sells well in the mass media.
They did that with us too, when 20% of the young people had tried disposables, the end result was a flavor ban.
We have existing laws in place making it illegal to sell vapes to under 18's and a 20mg nic limit plus all the TPD restrictions but enforcing that doesnt really happen so how they intend to enforce new laws will be interesting.
