Drug researchers are urging the Government to weigh up the potential health risks of cannabis reform.
Latest public opinion polls shows a majority of people want it. But Massey University drug policy expert Chris Wilkins says any change needs to be carefully thought out.
"The main point is a lot of things like alcohol and tobacco have known serious health risks, but that doesn't mean we prohibit them. Occasional use of cannabis has probably really modest health risks."

Dr Wilkins says strict regulatory and education policies would promote healthy use of the plant.
"We shouldn't treat cannabis like we do any other commodity in the supermarket - we've got to be a bit more careful about how we give people access to it and who should be using it."
He says calls for reform are only going to get stronger.
