A mother spoke about the devastating effects it had on her son and, as we know from those who've contacted us, her story is not unusual.
So, well done to those who have taken a stand and made their voices heard on this issue, including those who joined protests in Rotorua and around the country.
Of course not everyone will be pleased.
Users (and some non-users) argue people should have the right to choose what they put into their bodies, and that alcohol, tobacco and fatty foods and fizzy drinks cause more health problems than synthetic cannabis.
Others say it's impossible to ban the drug because it comes in so many forms and that making something illegal is not going to stop people doing it.
That is a debate that is sure to continue, as it should, before more definitive laws are eventually made.
So if you have an opinion, make sure you keep expressing it.
