It shouldn’t make a difference where you buy your products from – including e-liquids and pre-filled devices – as all vaping products should meet the same safety and quality standards.
Sadly, there is a small minority of rogue traders who are flouting the law and supplying illicit, non-compliant goods.
To be safe, only buy from reputable retailers and online stores and be sure to look out for red flags that products may not be legal – i.e., the tank size exceeds 2ml or there are no health warnings on the packaging.
