New NHS ‘Cannabis Clinic’ Announced as Kings College, Institute of Psychiatry Joins the ‘Green Rush’.

Dr Marta di Forti: “Cannabis-induced psychosis is a crisis which cannot be ignored”.

Mail on Sunday, 30th June 2019. NHS is forced to open Britain’s first clinic for cannabis psychosis to treat addicts of the mind-altering drug

Daily Telegraph, 30th June 2019. NHS opens first ever cannabis clinic as mind-altering ‘skunk’ fuels psychosis among users

Daily Star, 30th June 2019. First NHS clinic for weed addicts launched to treat cannabis-induced psychosis sufferers

The Times, 1st July 2019. NHS opens its first clinic to treat cannabis psychosis

Dr Di Forti, Professor Murray and their colleagues at the King’s College Institute of Psychiatry live in a bubble that is not replicated anywhere else in the world. The fantastic and frightening statistics that they publish are achieved through the use of complex, esoteric algorithms that generate theoretical projections which are regularly challenged by every other research team across the world working on the same subject.

Nevertheless, in the UK their theories are accepted as fact. Vigorously promoted by the King’s College press office, dutifully sensationalised by the Daily Mail and rarely challenged by other mainstream media, they are part of the anti-cannabis mythology which has a stronger foothold in the UK than any other country in the world.

Despite their best efforts, repeating the same or similar studies over many years, there is no evidence that cannabis causes psychosis, merely observational studies that show some people who are diagnosed with psychosis have used cannabis. Similar studies also show an association with drinking milk, energy drinks, using a skateboard, playing computer games or living in areas with heavy traffic pollution.

Research conducted at the Universities of Bristol and Cardiff, validated by further work at University of York, shows that the risk of a diagnosis of psychosis correlating with cannabis consumption is about 1:20000. See: By comparison the risk of being struck by lightning in a lifetime is 1:3000. See: This puts the risk into proper perspective and explains why nowhere else in the world, including where far more potent varieties of cannabis are legally available, is this a problem of any significance.

A few unfortunate souls will need treatment for psychosis where cannabis, probably with other substances, has been a component factor in their illness but the risk of this is infinitesimally small and compared to the panoply of other substances, activities and experiences we indulge in, completely irrelevant to 99% of people.

This clinic is another example of the skilled PR operation which enables Kings College to continue repeating this research year after year without ever discovering anything new or useful. It’s also clear that they want their share of the ‘green rush’ of huge investment funding going into cannabis as legalisation continues its unstoppable and very welcome roll-out across the world.

Legally regulated cannabis will result in a safer, happier, wealthier world for everyone and far better protect those very few people who are vulnerable rather than leaving the market under the control of gangsters.

  1. This tactic is unsurprising as acceptance of cannabis both within a “medicinal” context and”recreational” context is increasing exponentially and the government, in my view are trying every dirty trick they can dredge up to try and find a justification to reverse the rescheduling of cannabis.under the misuse of drugs, regulations 2001. I have deliberately put medicinal and recreational in quotes because, in my view the two roles tend to overlap,( some forms of recreation for example have a therapeutic element)

  2. TBH it strikes me as a bit hypocritical, and certainly not useful, to claim that others “live in a bubble” and then make the blanket claim that “there is no evidence”.

    There demonstrably *is* evidence, but of course it’s not as black as Dr Marta and co would have us believe, or indeed at white (or green, heh) as you would. *Transient* psychosis has been observed in a small number of patients, but only at ridiculously high doses.

    This was in a sativex paper from a while back that I only read very recently, but I’ve seen similar in other papers over the years too.

    Yes, the way the home office and a select group of medical “professionals” spout nonsense is frustrating, and the relentless way the tabloids pounce on this crap is simply infuriating – the nation has had this propaganda shoved down its’ throats for years, and many otherwise intelligent people now accept this as “truth”.

    But please, let’s remain *rational*, and not stoop to their level of re-interpreting facts.

    • There is no evidence of a causal link between cannabis and psychosis. I accept, of course, that there is lots of evidence of correlation because it has been furiously studied in a vain hope to show causation. You can certainly create transient psychotic symptoms by an intravenous feed of pure THC – but that’s not cannabis!

      You will find an admission of this buried deep in the text of every di Forti, Murray, et al study but of course everything else they do about presenting their results suggests otherwise.

      This is the ‘grand deception’ they are engaged in. It’s what keeps them funded to keep churning out the same, repetitive and totally pointless studies year after year after year.

      • This is true there is definitely no evidence that smoking collie causes psychosis, yes it is fact that lots of people who present at some medical facility with these symptoms have smoked collie. This is simply because today it is ubiquitous, everybody has or is smoking collie.
        This is a tenuous connection, not a cause.
        Hypocrit my arse these people do exist inside their own cosy academic bubble and as Peter descibes churning out the same repetitive crap.
        I find it annoying that people keep talking about medicinal and recreational Cannabis, yet the people buying these products have no idea they are derived from Hemp they think its derived from a real Cannabis strain.
        This is just another facet of the same deception.
        Back in the day old time people knew what to do with Hemp they made rope with it and consumed real Cannabis for everything else they did not have an agenda they were just making life.
