After almost 350 submissions and three days of public hearings to the Parliamentary inquiry in NSW, the overwhelming evidence for changing laws around cannabis is becoming impossible to ignore.

The inquiry is of keen interest in Victoria because it is hearing evidence into the exact same Bill introduced in three states - Victoria, NSW and Western Australia.

The strategy is to create pressure in all three states to make legalisation inevitable.

The NSW inquiry has heard from a number of health and legal professionals, as well as medicinal cannabis companies and those with lived experience of prohibition.

It has one more day of hearings to go before producing a report in October, timed to coincide with the NSW Drug Summit in October and December.

There has been overwhelming support for drug-driving and workplace drug-test reform, in addition to the legalisation, or decriminalisation, of adult-use cannabis.

In an interview with ABC Radio and reported in Cannabiz, NSW Legalise Cannabis MP Jeremy Buckingham said:

"The inquiry is building a body of evidence that will, I think, convince NSW Premier Chris Minns, all state premiers, and ultimately Anthony Albanese, that the legalisation of cannabis makes socio-economic sense and is a reform that can be done safely to great benefit in Australia.

"We are receiving a massive amount of evidence from health professionals, legal professionals, former police and experts in the field, that clearly indicates that it's a reform that can be done, and must be done.

"Ultimately, Chris Minns and other legislators won't be able to ignore the evidence."
