Dr Stuart Jones Mischaracterises COPD Findings, Risks Driving Smokers Back To Cigarettes
A recent statement by Dr. Stuart Jones claims 'hard data' prove that vaping alone causes COPD. A closer look at the Nicotine & Tobacco Research paper does not support Dr Jones's assertions and underscores vaping's potential for harm reduction.
Key Facts
Baseline COPD Prevalence: Only 1.3% of exclusive e-cigarette users had COPD at enrollment, versus 2.7% of never-smokers/never-vapers - a 67% lower COPD rate in the vaping group.
Incident COPD Over 3-4 Years: While vapers did develop new COPD cases at a rate 2.3-times higher than never-users (adjusted hazard ratio 2.29 [1.42–3.71]), they simply reached parity with the never-smokers/never-vapers group's higher COPD prevalence.
No Evidence Vape-Driven Epidemic: End-of-study COPD prevalence in exclusive vapers mirrored the never-user group's baseline level - hardly the 'surge' implied by Dr. Jones's sound-bite.
Short Follow-Up: COPD is a decades-long disease. A 3½-year window can only capture early or preexisting lung damage - not new COPD caused by vaping.
Harm-Reduction Evidence: Clinical research shows that smokers with COPD who fully switch to vaping experience fewer flare-ups, improved symptoms, and stabilized lung function compared to those who continue smoking.

'Cherry-picking sensational headlines over sober science does a disservice to public health,' says Jonathan Devery, Chair, Vaping Industry Association of New Zealand (VIANZ).
'Vaping is not risk-free, but for adult smokers unable to quit, it remains far less harmful than cigarettes - and misrepresenting these findings could drive people back to the most lethal form of nicotine delivery.'

Aphasia advocates help share message
The difficulties experienced by people living with aphasia are being spotlighted this month, as New Zealand marks Aphasia Awareness Month. Aphasia is a disorder of communication, where speaking, reading, writing and/or understanding language is impacted. Dunedin-based Aphasia New Zealand community aphasia adviser and speech language therapist Meryl Jones said many people in the community did not know what aphasia actually was, despite 29,000 New Zealanders living with the condition. Aphasia is caused by damage to the language centre in the brain (usually in the left hemisphere), most commonly due to stroke — about one-third of people who have a stroke will experience aphasia. Brain injury, tumour and infection can also result in aphasia, which affects each person differently. Ms Jones said aphasia was a difficult concept for the general population, resulting in people with aphasia often withdrawing from social contact. The situation was summed up by the saying "until you've met it, you just don't get it", she said. "So, we are working to raise community awareness of aphasia and its impact on people's lives," she said. People with aphasia had difficulties with communicating, but this did not mean their cognitive abilities were impaired, making it extremely frustrating. "Because of the very nature of aphasia, it is difficult for people living with it to advocate for themselves," Ms Jones said. "People with aphasia say they would like people to be more patient and to give them time to get out what they want to say — rather than making assumptions or finishing their sentences for them," Ms Jones said. "Other people can help by adapting their own communication and getting to know the person with aphasia's own way of communicating." For therapists, the aim was to give people with aphasia a functional way of communicating, using their strengths, which may include non-verbal strategies, such as gestures. "We also try to educated the people around them, training up their communication partners to give them the right support. "A major goal for us is to support people with aphasia to participate in life." Ms Jones works with a group of Dunedin people who have aphasia through a Korero Club, which meets fortnightly on Tuesdays to enjoy face-to-face conversation. "We have had great friendships formed among the group, with some describing it as the highlight of their week," she said. There is also the Dunedin Aphasia Support Group, a community support group for people with aphasia and their partners, families, whanau and/or carers, which meets on Fridays in Mornington. This group can be contacted via facebook. • For more information and/or support for aphasia, email dunedin@ or phone Meryl Jones on 021 177 0587.

Government Gaining Ground In Pursuit Of Supercritical Geothermal Energy
Minister for Science, Innovation and Technology The Government is making good progress on its exploration of supercritical geothermal as a potential energy source, with a governance group established and potential drilling sites being identified, Regional Development Minister Shane Jones and Science, Innovation, and Technology Minister Shane Reti say. 'We need to drill an exploratory deep well to prove the commercial viability of supercritical geothermal energy. We are about a year from starting to drill but we are getting closer to locating potential geothermal fields in the Taupō Volcanic Zone,' Mr Jones says. The choice of sites will be based on rigorous data, scientific research, and engineering experience. The location of the first exploratory well site is expected to be finalised later this year. The Coalition Government has ringfenced $60 million from the Regional Infrastructure Fund to invest in exploring the potential of supercritical geothermal technology to help secure New Zealand's future energy needs. 'It will be a big challenge but the potential if we can do it will be globally ground-breaking,' Mr Jones says. 'Our geothermal resources aren't affected by weather in the same way renewable energy sources such as hydro, solar and wind are. This is particularly important in the context of energy security for New Zealand's future prosperity.' Geothermal energy is sourced from extremely hot rock heated by magma. At present, conventional geothermal wells are drilled to a maximum depth of about 3.5km. Scientists believe by drilling beyond this, possibly to 6km deep, the energy output could be up to three times greater than traditional geothermal energy generated from steam. 'With the search for potential exploratory well sites being narrowed down, we need to develop and prove the drilling and engineering systems for extracting the energy. Supercritical geothermal wells require casing materials that can withstand both high temperatures and potentially corrosive supercritical fluids,' Dr Reti says. 'I'm issuing a challenge to the New Zealand science and research community – academics, scientists and industry - help us find the solution. A lot of innovative research is happening across the country in pockets that could lead to the solution we need. It will be through these experts and sectors coming together and working collaboratively that we will crack this,' Dr Reti says. The Ministry of Business, Innovation and Employment (MBIE) and GNS Science are leading the initiative, with MBIE setting up a Supercritical Geothermal Governance Group tasked with providing oversight and advice, and supporting the successful delivery of the project. The Supercritical Geothermal Project Board members are: Chairperson - Hon Tim Groser – has 35 years career in trade and economic issues. He was former NZ Ambassador to the United States, former Minister of Trade, and Minister for Climate Change. Dr Charlotte Severne (Ngāti Tūwharetoa, Ngāi Tūhoe) is the Māori Trustee and leads Te Tumu Paeroa - the Office of the Māori Trustee. She holds a PhD in geology and has held various governance leadership roles within the primary and energy sector. Keith Turner – an electrical engineer and business executive with more than 50 years' experience in the electricity sector, including being the chairman of Transpower. He is a Distinguished Fellow of Engineering New Zealand. Jason Hollingworth - over 30 years' experience in a range of senior corporate finance roles. His is currently the CFO at Vector. His previous roles include being CFO of SKY TV, TelstraClear, and investment manager for Ngai Tahu Holdings. A total of $5m of the $60m government funding will be drawn down for work on the detailed design and costs of drilling the first exploratory well. Mr Jones will launch a geothermal strategy for New Zealand during Geothermal Week in Taupō in July.

Oceans Symposium Highlights Need To Establish Independent Oceans Commission
Press Release – EDS An overarching theme of the day was the power of collaborative effort in achieving positive change. The Environmental Defence Society's annual environmental summit kicked off yesterday in Auckland with an Oceans Symposium. Speakers highlighted that the marine environment is in serious trouble. In some parts of the country, the sea is warming three times faster than global trends. We heard that the Hauraki Gulf is in an impoverished state. Sediment is taking its toll. Kina barrens have taken over large tracts of the coast. Ecosystems are responding in worrying ways. New Zealand's marine productivity has decreased rapidly since 2022. As NIWA scientist Matt Pinkerton advised, 'it is as if some threshold has been crossed'. We were warned to expect unpredictable changes. International keynote speaker Dr Salvatore Aricò, CEO of the International Science Council, led the discussion by talking about the importance of integrated marine spatial planning, and 'bottom up' approaches complementing 'top-down' policy. He talked about the need to inform dialogue with science. Linda Faulkner captured a wider concern that translating science into marine policy is a 'massive issue'. But there are excellent examples of science informing collaborative change. We heard about the success of marine protection in Fiordland, which has helped rebuild the rock lobster population there, and the promising work by University of Auckland scientists to restore kelp forests in the Hauraki Gulf. EDS CE Gary Taylor interviewed Fisheries and Oceans Minister Shane Jones, who confirmed he's committed to addressing kina barrens, including by considering rock lobster closures and sourcing funding to assist kina removal. Minister Jones said that his proposed changes to the Fisheries Act wouldn't cripple the paramountcy of fisheries sustainability, which is a good thing given Professor Stephen Wing's no-nonsense statement that the days of expansion of new fisheries into new habitats are over, and that we are now in a regime where restoration of fisheries is the most profitable game. When asked about rolling out regional fisheries plans, including for the Marlborough Sounds, Minister Jones agreed we need more. He said the Hauraki Gulf marine protection bill is imminent, and with respect to marine protection, we should bank 'good enough'. Trawl zones would not be created before the next election, which is disappointing. An overarching theme of the day was the power of collaborative effort in achieving positive change. Edward Ellison talked about the need for respectful, community-driven and collaborative processes which recognise cultural connection and have strong Treaty Partner engagement. The Symposium concluded with a panel debate about the merits of establishing a National Oceans Commission. There was consensus that such a body had merit, but it would need to be independent from government, bring iwi and hapū to the table, and have teeth. There was little support for another purely advisory body. David Attenborough's recently released movie 'Ocean' was highlighted as a must-watch for those interested in the future of the oceans. Overall, the key message from the Symposium was the need to act now, the need to act together, and the need to put the health of the oceans first.
