The Northern Advocate highlighted local lawyer Dave Sayes' concerns about the product last week and we urged retailers to not wait for the pending Psychoactive Substances Bill, which will ban these substances.
We urged retailers to take a moral stance and not sell these products.
Why? Because there are an increasing number of anecdotal horror stories emerging about K2.
This is a product that targets the youth market (chocolate-scented packaging, anyone?) and in doing so, does not divulge its ingredients.
Buy K2 and you are buying a mystery sachet of harmful ingredients.
Health concerns about K2 include suspicions that it can cause seizures and dramatically alter the user's personality.
The Northern Advocate contacted a health expert who confirmed that yes, he has seen people believed to be suffering the ill effects of synthetic cannabis use.
However, on an average night in emergency departments around New Zealand, it is alcohol - not synthetic cannabis - that remains society's problematic drug.
Having knocked K2 off, it seems there is still a mountain to climb when it comes to our attitudes to booze.
