The Times Picks up the Reefer Madness Baton from the Daily Mail

with one comment

Stigmatising cannabis consumers and patients with one-sided and biased reporting is irresponsible misinformation, not journalism

It’s that time of year, King’s College Institute of Psychiatry has started its fundraising round so it’s time for the annual cannabis and psychosis scare story.

Over the past 10 years, in January or February each year, a press release goes out with its lead researchers, Professor Sir Robin Murray and Dr Marta di Forti, pushing another set of extremely scary statistics about how cannabis is driving consumers insane.

This year, two things are different, Firstly, there’s no new study, just repetition of previous claims.  Secondly, instead of being led by the Daily Mail, it’s The Times that has taken up the role of terrifying parents and this year there’s also a new story about over-55s who are ‘addicted’ to cannabis.

The Times’ reputation as the newspaper of record and the supreme example of English-language journalism has been faltering for some time. The decline started, inevitably, when Rupert Murdoch bought the newspaper in 1981.  It’s now tabloid-sized and, surprisingly often, tabloid in its style and disdain for the truth. In the main it is still a good source of news reporting and has an honourable record in covering the increasing acceptance of and value in the medical use of cannabis.

However, starting in September 2021 with a major feature in the Sunday magazine by Megan Agnew,‘Cannabis psychosis: how super-powered skunk blew our minds’, it has become an uncritical promoter and advocate for everything that comes out of King’s College about cannabis.

Ms Agnew interviewed me at length several months before her piece was published and I dare say she spoke to other people on the reform side of the debate as well.  Certainly not one word of what I said made it into print.  It might as well be a paid-for advertorial for Marta di Forti and Robin Murray’s work.

I’ve met Robin Murray several times. In fact, I once sat next to him for two days in a conference held in the House of Lords. In person he’s nowhere near the anti-cannabis zealot he’s portrayed as in the press and there are other people in his team who I have worked with on research projects who I think, although they wouldn’t say it, are actually on my side!  Nevertheless, the message about their research that is portrayed in the media is clearly deliberate and it is wildly misleading.

This is best demonstrated by going to the Lancet website, where all the Murray/di Forti papers are published and reading the other scientists who debunk both the results and the methodology that Murray/di Forti use.  Of course, this never gets mentioned in the press. The Times has completely excluded it from all its coverage.  Go to https://www.thelancet.com/ and search for ‘High-potency cannabis and incident psychosis: correcting the causal assumption’. You’ll see a whole new perspective on King’s College and its scientists.

This obsession with demonising cannabis is centred on the UK, precisely because of the endlessly repetitive work carried out at King’s College and the appetite that British press has for sensationalising it.  Australia also suffers from it to some degree but nowhere else in the world experiences the same systematic, ludicrous scaremongering.  That’s not to say that the potential dangers of cannabis as a psychoactive substance are ignored, they’re simply given proportionate recognition.  Clearly anything that affects the mind can, potentially, cause harm and needs consideration, just as we do with alcohol, coffee, energy drinks and many medicines. Sadly there will always be casualties but provided we do all we can to minimise them, they do not justify prohibition.  The evidence is clear that always causes more harm than good and it is self-evident that harm is better controlled and casualties more effectively prevented in a legal environment, not in a market run by gangsters and organised crime.

 

BBC Horizon to Ramp Up Discredited Kings College ‘Skunk Scaremongering’

Dr Marta di Forti. Scientist or Skunk Scaremonger?

Tonight’s BBC Horizon is going to follow the long-established BBC policy of overstating and exaggerating the potential harms of cannabis.

From clips already released it is clear the programme is to promote as gospel truth the hysterical scaremongering and fanciful statistical projections coming from Dr Marta di Forti at King’s College London’s Institute of Psychiatry. This so-called scientist and her colleagues base all their conclusions on profoundly unscientific methods, false assumptions, bizarre statistical trickery and the misuse of the tabloid term ‘skunk’ as if it actually means something.

This is the way the BBC has always operated – to support the false narrative of the establishment about cannabis, to demonise it, to minimise if not ridicule its medicinal benefits and to cherry pick evidence and biased opinion to support its case.

Anyone with any real knowledge of cannabis who has spent any time properly reseraching the evidence will know that Dr di Forti’s projections and claims are ridiculous.  This is a British phenomenom.  It occurs nowhere else in the world.  Every other nation’s media, scientific and medical community takes a balanced and realistic view and recognises that cannabis is largely benign and for 99% of people, 99% of the time is harmless.  Perhaps most instruictive is that virtually nowhere else in the world will you hear the word ‘skunk’ used by real scientists.  Originally the name of a specific strain of cannabis it is now merely a scary word used to frighten people and it has no specific or defined meaning.  Its use is, in fact, the very opposite of science.

But don’t take my word for it. In a devastating critique of di Forti’s latest 2019 study, read the words of leading scientists from Australia and the Netherlands as they dismantle di Forti’s wild overclaiming and statistical trickery: High-potency cannabis and incident psychosis: correcting the causal assumption

A CLEAR Response to the Institute of Psychiatry’s Latest Cannabis and Psychosis Scaremongering

with 2 comments

Dr Marta di Forti

The Insititute of Psychiatry is today announcing its latest study on the links between cannabis and psychosis – ‘The contribution of cannabis use to variation in the incidence of psychotic disorder across Europe (EU-GEI): a multicentre case-control study’.

For many years, its leading lights Professor Sir Robin Murray and Dr Marta di Forti have published study after study attempting to show a causal link between cannabis use and psychosis.  They have never managed to achieve this and despite concerted efforts, the link cannot be described as anything more than extremely tenuous.  The number of people that may be affected is infinitesimally small, while hundreds of millions of people worldwide consume cannabis regularly without any ill effects.

Every year in the early spring Dr di Forti and Professor Murray publish their latest study on the subject. It’s always interesting to see the latest iteration of their work although all the studies are remarkably similar

Cannabis is a psychoactive substance so clearly it can have an effect on mental health.  We know from at least 10,000 years of human experience that for most people this is a beneficial effect.  The number of people that suffer negative effects is difficult to quantify but we can be certain that it is very small. Research published in the journal Addiction shows that in order to prevent just one case of psychosis, more than 20,000 people would have to stop using cannabis. http://onlinelibrary.wiley.com/doi/10.1111/add.13826/full

This level of risk must be compared with other risks to give it any meaning. For instance, if the risk of a diagnosis of psychosis correlating with cannabis use is 1 in 20,000, the risk of being struck by lightning in one’s lifetime is about 1 in 3,000. This puts the risk into a realistic perspective.

It’s also important to understand that this latest study does nothing to show that cannabis actually causes psychosis, only that there is an association or correlation with cannabis use.  There may be other correlations which may or may not be much stronger.  For instance the populations studied may also use tobacco, drink wine, eat spicy food, live in a city centre or exercise regularly or not at all.  Similarly it cannot be shown that any of these factors are the cause of psychosis.

It is also interesting that the study deems an average of 14% THC to be high potency cannabis.  Throughout the USA and Canada, average THC content now exceeds 20%, sometimes as high as 35% and there is no reported increase in rates of psychosis.

Finally, it has to be said that Dr di Forti is well known for her theoretical projections about cannabis use which can be quite alarmist. Thankfully, they have never been reflected in actual healthcare records and the number of cases of psychosis correlating with the use of natural cannabis in the UK remains very low, no more than a few hundred.  There are many, very much more risky activities to be concerned about.

What is certain is that the way safely to manage the risks of cannabis, even though they are so low, is in a legally regulated environment. In this case products are labelled so that the content is known, quality is maintained to a standard avoiding contamination and impurities and if anyone does experience problems they can seek help without having to confess to a crime. Age limits can also be enforced ensuring that children do not have the easy access to cannabis that they have, for instance, in the UK.

‘Skunk’ Drives Tabloids And Politicians Mad.

with 6 comments

Tom Chivers, Ian Dunt and Jonathan Liebling expose the dreadful reporting of the latest cannabis harms study from the husband and wife team of Professor Sir Robin Murray and Dr Marta Di Forti.

The British tabloid press has long been engaged in the corruption of our society and successive governments’ ability to deal with drugs policy by its sensationalism, distortion and dishonesty.

In fact the worst offender now is the Daily Telegraph, a tabloid in everything except format. It now eclipses the Mail newspapers for inaccurate, misleading and distorted reporting on all aspects of drugs policy. Its science and medicine writers are either deliberately engaged in deception or utterly incompetent. Virtually every story it publishes on drugs these days has to be retracted but you never hear about it because it’s buried in a tiny, tiny correction.

Here’s what happened to its ridiculous claim recently “cannabis as addictive as heroin”

DT headline 071014

The Mail newspapers can’t resist the stories about the miraculous medicinal benefits of cannabis because they make such good sensationalism. So although they still publish hogwash, like this latest distortion, they’ve actually become more balanced almost by mistake.

Why is the British press so incompetent and/or malevolent on drugs? Is it anything to do with the £800 million pa that the alcohol industry spends on press advertising? I don’t know. Maybe it just likes to appeal to the fast dwindling band of bigots that actually buy newspapers these days.

We are a laughing stock across the world for the idiocy of our press and government, particularly in respect of cannabis. In Canada and Israel, hospitals provide elderly patients with cannabis vapourisers on trollies, so strong is the evidence for its beneficial effects on aging and dementia. Here of course we prefer to let them lie in their own excreta while feeding them with scaremongering nonsense, distortion and exaggeration of scientific studies.

Sugar, peanuts, hay fever remedies, aspirin, paracetamol and traffic fumes cause far more health harms than cannabis.

In Colorado, in 2014, $44 million in cannabis tax revenue was ringfenced for schools and hospitals. Since legalisation, crime and fatal traffic accidents are down 15%, murder is down 50%.

Far too sensible for Britain isn’t it? And it’s the work of our gutter press that prevents such progress here because politicians still give newspapers far too much respect.
