Could cannabis and psychedelics help treat eating disorders?
The Australian-led survey of 7600 self-selected respondents across 83 countries has revealed that cannabis and some psychedelic drugs, including 'magic mushrooms' and LSD, were the most effective among self-medicated, non-prescription drugs for alleviating symptoms associated with illnesses including anorexia nervosa, bulimia and binge eating.
Published in JAMA Network Open this week, the research has been led by PhD student Sarah-Catherine Rodan at the University of Sydney's Lambert Initiative for Cannabinoid Therapeutics. Professor Iain McGregor, academic director of the Lambert Initiative, is senior author on the paper.
About 1 million Australians live with an eating disorder, and almost one-third of adolescents in this country engage in disordered eating in any given year, according to National Eating Disorders Collaboration. They are notoriously difficult to treat and, according to the Butterfly Foundation, have the highest mortality rates of all psychiatric disorders.
Rodan says the study found that beyond cannabis's reputation for stimulating appetite, it offered a variety of potential benefits to users suffering from illnesses such as anorexia nervosa, bulimia nervosa, binge-eating disorder and avoidant/restrictive food intake disorder.

'Cannabis has mood-elevating, anxiety-reducing gastroprotective and anti-nausea properties,' she says. 'Patients with avoidant/restrictive feeding intake disorder and anorexia nervosa report symptoms of anxiety and related abdominal pain and nausea, which can reduce appetite and exacerbate disordered eating.
'Cannabis also has anxiolytic properties and may reduce food-related anxiety and guilt.'
The survey also investigated ways participants were ingesting drugs, which affected the positive or negative outcomes.

Brace yourself for ‘giant hail' as storms increase along east coast
Hailstorms will become more frequent in Brisbane, Sydney and Canberra, and the size of the stones that the storms create will grow in Canberra, Sydney and Melbourne as the climate warms over coming years, new modelling shows. With every degree the atmosphere warms, it can hold 7 per cent more moisture, creating more turbulent conditions and increasing the likelihood of damaging hailstorms, said Dr Tim Raupach, author of a paper on projected hail damage in major Australian cities. His modelling compared the historical incidence of hailstorms over the cities, with conditions expected in a scenario where the climate warms by 2.4 degrees by 2080. The result was that while there may be more hailstorms in Brisbane, the chances of 'giant hail' being produced became far higher in Sydney, Canberra and Melbourne. 'In the historical scenario, Melbourne would be expected to see a 100-millimetre hailstone – 10 centimetres – every 20 years, but in the future scenario, it would be expected to see one every three years,' said Raupach, whose paper was published in the journal Geophysical Research Letters. In Sydney and Canberra, as the atmosphere warmed, the chances of giant hail hitting the cities increased from every three years to every two years. Raupach, a researcher in atmospheric science at the UNSW Climate Change Research Centre, said the purpose of the study was to compare the two atmospheric eras to explore the potential impact of climate on hail. 'If we had all the computing power in the world, we'd run multiple simulations,' he said.

‘Silent killer': Taxpayer media finds ‘burning wood' a threat to your health
Sky News host Paul Murray discusses how taxpayer-funded media has found wood heater pollution as a "silent killer" in Australia. 'Today, taxpayer media have finally found the big killer, the big danger, the thing we must do to save lives here at home and change the climate globally, and it is the fireplace at your joint,' Mr Murray said. 'Yes, I am talking to you, right now if you are currently warming in an Australian winter with wood, either behind the glass, in the heater or in a beautiful fireplace where you can hear the crackle, well, guess what, my friends, you are part of the problem.'
