Support to legalise recreational cannabis in decline – Helius


The prospect of ending wider cannabis prohibition looks increasingly unlikely. Over the last nine months, the percentage of New Zealanders who would vote for legalising the personal use of cannabis has declined at a near linear rate of around 10% per quarter. Support is now well below a majority, at 39%.

That’s according to New Zealand’s most significant series of independent surveys, tracking nationwide opinion on cannabis law reform, ahead of the Government’s 2020 binding referendum on whether the personal use of cannabis should be legalised.

Commissioned by New Zealand’s largest licensed medicinal cannabis company, Helius Therapeutics, the three surveys conducted by Horizon Research since November 2018 show a clear trend.

“On the current trajectory, the referendum is heading for certain defeat. The numbers all point to the non-medical use of cannabis remaining in a gang-controlled black market. Unless there’s a public information campaign to help Kiwis make a more informed choice around the pros and cons of legalisation, organised crime is set to be the only referendum winner,” says Paul Manning, Executive Director of Helius Therapeutics

The latest survey of over 1,000 New Zealanders conducted at the start of this month, shows support has fallen from a clear majority, at 60% in November, to 52% in April, to just 39% now.

At the same time, 47% of adult New Zealanders are against legalising the personal use of cannabis – up 10% from April (37%) and nearly double the number in November (24%). Those with no opinion sit at 14%, which has remained relatively steady.

Mr Manning is not surprised much of middle New Zealand is turning against the prospect of legalisation, saying key messages from cannabis proponents are not getting through.

“A vacuum of information in recent months has been filled by fear. This is the first set of comparable independent surveys, conducted by the same research company, and the downward trend is staggering. Those pushing for liberalisation will be particularly alarmed to see the substantial drop off in support, particularly from Green Party voters and younger Kiwis,” he says.

The number of Green Party voters in favour of legalising cannabis for personal use has fallen the most, by 20%, from 83% in April to 64% this month. Labour Party supporters in favour have fallen from 63% in April to 46%.

At the same time National Party supporters against legalising cannabis for personal use have risen from less than half to nearly two-thirds. In November 48% of National voters were against, rising to 60% in April, and 64% now.

For all age groups under 65, support has fallen. In fact, for younger and middle-aged New Zealanders, support has dropped off quite significantly since April.

For 18 to 24-year-olds, support has fallen from 68% in April to 56% in August; for 25 to 34-year-olds from 68% to 50%; for 35 to 44-year olds from 55% to 33%; for 45 to 54-year olds from 53% to 39%; and for 55 to 64-year olds from 38% to 27%.

Support remains relatively split between men and women, with 39% of men now in favour and 40% of women, albeit a higher proportion of females were in favour in April at 55% compared to 48% of males then.

Mr Manning says that without a co-ordinated, nationwide campaign to deliver balanced messaging around personal cannabis use, efforts for wider reform have been impeded.

“Proper funding for an advocacy campaign is difficult because no individual, business or organisation really knows what the commercial sector would look like in New Zealand.”

He says wherever Kiwis sit on the personal use of cannabis, there’s merit in regulation that should be considered, and that case needs to be put forward sooner rather than later.

“Rather than waiting until next year to tell Kiwis how cannabis reform could benefit New Zealand, the time for more balanced education is now.”

Mr Manning says while Helius is focused exclusively on developing medicinal cannabis products, legalising personal use would undoubtedly change the future market dynamics.

“Legalisation isn’t just about recreational products. It could, for example, enable the creation of a wider variety of over-the-counter cannabis-based wellness products. These could include non-prescription health supplements and cosmetics.”

In a broader sense, he says, although full legalisation may present some challenges, it would generate significant tax revenue, create employment opportunities, and control quality standards. Legalisation would also mean over 320,000 New Zealanders were no longer committing a crime every day, purchasing products in a market controlled by gangs.

Commissioned by Helius Therapeutics and carried out independently by Horizon Research, the results are from of a series of nationwide online surveys of adults representing the 18+ population, accurate at the last census. The most recent survey of 1,003 respondents was conducted on 3 to 4 August 2019. Respondents were members of a third-party nationwide research panel. Results are weighted by age, gender and party voted for at the 2017 general election. At a 95% confidence level, the maximum margin of error is ±3.1%.

  1. If it is legalized the marajuana sold would need to be tested and sold with the added tax and GST. These extra costs would need to be passed on so the gangs product which is untested and tax free would be cheaper so heavy users would still go to the gangs for their supply

    Watch/listen to The Sacred Plant Series one
    As a sufferer of Multiple Sclerosis (caused by mercury in vaccinations I had to have when a young student nurse in the late 1950s) for 4 decades now, I am certain that the pain I experience day & night would virtually disappear if I were able to eat raw, the flowers/tops of the cannabis plant The majority of New Zealanders (& especially politicians) are woefully ignorant about the safe & effective action in the human body of cannabis in its various forms. IMO, the worst way to use cannabis is to smoke it. So far as I know, the best research was done in Israel at the time when this 1st series was made.

    The doco series can be purchased but interested readers will need to find out themselves how to access & buy the series. (Being as unwell as I am, I cannot do for others what they can do by/for themselves.)

    There has been a 2nd series made but I haven’t seen it & can’t afford to buy it.

    • “As a sufferer of Multiple Sclerosis (caused by mercury in vaccinations I had to have when a young student nurse in the late 1950s) ”

      Is there any science-based evidence for that claim?

  3. to Frank Macskasy . Mercury is a very potent neurological poison – you can check this fact yourself. When I had the vaccinations I wrote of, 2 of them caused me to become so sick that I could not go on duty – almost a crime when I was a young student nurse. The typhoid vaccination caused me to be ill & (I think) the other was for smallpox (not a disease in NZ then or now). Once when I was very sick, a young houseman arrogantly told me that I didn’t have a temperature & so I could go on duty. I scathingly told him that he hadn’t recorded my pulse rate (which at the time was 120 beats/minute. DOCTORS! I could write a book & more about them! (Decades later a very experienced & knowledgeable doctor said to me at a hiu I attended, that he was certain that mercury in the vaccines was the cause of the M.S. I had prior determined that myself. One of 5 siblings, I was the only one to become ill with multiple sclerosis. I was the only one to have all those vaccinations (which included the SV40-contaminated polio vaccination (& the govt. KNEW it was contaminated!) In 1981 the “tatty” Weekly TRUTH exposed what successive gutless governments had hidden from the people. Call N.Z. a “free country”? I remain very angry that I have suffered much pain day & night for more than 60 years! IMO, I am well overdue for compensation!
