Khat out of the bag

Finding myself at a loose end yesterday I decided I’d try and track down one of London’s mafrishes – a type of cafe where people from the capital’s Ethiopian, Somali and Yemeni community chew the psychoactive plant khat.

I’d heard about a Somali cafe on Lewisham Way and thought that was as good a place as any to try. The cafe owner first looked a bit baffled when I walked in and asked about khat but he sat me down, gave me tea, and went out back to ask his associates.

“Sorry, there’s no khat in Lewishman. We have internet?” he suggested while gesturing towards the empty computers at the back. I kindly declined but in reply he suggested I go to Streatham. “There are lots of restaurants there”, he assured me.

Streatham is huge, so I arrived at one of the rail stations and just decided to walk south. Slowly I became aware that there were more Somali-looking faces around but there were no cafes to be seen.

Just through chance I noticed some Somali cafes off a side street and walked into the first one I saw. “There’s none here, but next door”, I was told. The people in the next cafe said the same, as did the next, and the next, until I came to an unmarked door.

“Just go in” a cafe owner called to me from across the street, so I walked in.

The place was little dark but quite spacious. My fantasies of an East African cafe translocated to London quickly faded as my eyes adjusted to the trucker’s cafe decor. Inside, there were four guys watching the news on a wall-mounted TV.

The cafe owner greeted me as I entered. I asked my usual question about khat and he looked at me, a little puzzled.

“You know, khat, to chew?” I ventured. A furrowed brow. Thinking. “Oh, chat. Yes, we have bundles for three pounds and bundles for seven. Which do you want?”

“Give me one for seven” I said. “No problem” he replied cheerily. “Have a seat”.

This wasn’t the first time I had tried khat. Many years ago, when I was an undergraduate in the Midlands, I discovered khat in an alternative shop. It was sold as a natural curative soul lifting wonder plant from the fields of Africa.

I bought some, didn’t really know what to do with it, and just began to ‘gently chew’, as the leaflet advised, while walking through the streets of Nottingham.

So when my bundle of khat arrived, I just picked out some stems and began chomping on one end. “Wait, wait, stop!” they shouted in unison. “We’ll help you” said one and I was joined by the cafe owner and a friend. “Anyway, he said”, “you’re not allowed chew alone, it’s a social thing.”

I was given a bin to put beside my table, was shown how to strip off the stems and pick out the soft parts, and how to chew slowly. I was provided tea and water on the house and told to keep drinking fluids. Apparently, it can be a little strong on the stomach and the plant makes you go to the toilet a lot as, I was told, ‘it speeds up the body’.

I had the company of the cafe owner, a Somali Muslim, and his friend, an Ethiopian Christian.

Over the next two hours we chewed and talked. Ethiopian politics, football, living in another country, khat in Somalia, Haile Selassie, religion, languages, Mo Farah, stereotypes of Africa and family life in London.

People strolled in an out of the cafe. Some in jeans and t-shirt, others looking like they’d just walked in from the Somali desert. Everyone shook my hand. Some bought khat and left, others joined us, all the while chewing gently and drinking sweet tea. At one point I asked the Christian guy why he wore an Islamic cap. He whipped off his hat. “I’m bald” he said “and it’s the only cap you can wear inside” which sent me into fits of laughter.

Khat itself has a very tannin taste and it is exactly like you’d imagine how chewing on an indigestible bush would be. It’s bitty and it fills your mouth with green gunk. The sweet tea is there for a reason.

The effect of the khat came on gently but slowly intensified. It’s stimulating like coffee but is slightly more pleasurable. There’s no jitteriness.

It reminded me of the coca plant from South America both in its ‘mouth full of tree’ chewing experience and its persistent background stimulation. But while coca gave me caffeine-like focus that always turned into a feeling of anxiety, khat was gently euphoric.

My companions told me that it lifts the spirits and makes you talkative. They had a word, which for the life of me I can’t remember, which describes the point at which it ‘opens your mind’ to new ideas and debate.

The active ingredient in khat is cathinone which has become infamous as the basis of ‘bath salts’ legal highs which chemists have learnt to create synthetically and modify. But like coca, from which cocaine is made, the plant is not mental nitroglycerine. It has noticeable effects but they don’t dominate the psyche. It’s a lift rather than a launch.

The guys in the cafe were not unaware of its downsides though. “Don’t chew too often” they told me “it can become a habit for some”. I was also told it can have idiosyncratic effects on sexual performance. Some find it helps, others not so much.

Not everyone was there for khat. Some guys chewed regularly, some not at all, some had given up, some only on special occasions. Some just came to hang out, drink tea and watch the box.

Towards the end when I felt we had got to know each other a bit better I asked why the cafe was unmarked. The owner told me that while khat is legal they were aware of the scare stories and were worried about the backlash from less enlightened members of the community. ‘Immigrants sell foreign drug’ shifts more papers, it seems, than ‘guys chew leaves and watch football’.

Eventually, I said my goodbyes and decided I could use my buzz to go for a walk. I made London Bridge in a couple of hours. But I think my newfound energy came as much from the welcome as it did from the khat.

An online sickness

The first academic review article on ‘Munchausen by Internet‘ – where people fake the identity of an ill person online – has just been published in the Journal of Medical Internet Research.

Munchausen syndrome is a common name for facticious disorder where people consciously fake illnesses for their own gain.

This is distinguished from malingering – where the gain would be something obvious like money, drugs or missing military service – and instead the gain from factitious illness typically includes the indirect benefits of faking – like being cared for, avoiding family conflict and so on.

The person is deliberately faking but they may not be fully conscious of all the emotional benefits – they might just say ‘it feels right’ or ‘it helps me’.

Obviously, this has been a problem for millennia but there has been an increasing recognition that the phenomenon happens online. People take up the identity of someone with an illness that gives them a special place in an online community.

This could be a standard online community where their ‘illness’ becomes a point of social concern, or their pretence could allow them to participate in an online community for people with certain disorders or conditions.

The article gives lots of example and some ways of spotting Munchausen fakers that also gives an insight into their thinking:

  • Posts consistently duplicating material in other posts, books, or health-related websites.
  • Characteristics of the supposed illness emerging as caricatures.
  • Near-fatal bouts of illness alternating with miraculous recoveries.
  • Fantastical claims, contradicted by subsequent posts, or flatly disproved.
  • Continual dramatic events in the person’s life, especially when other group members have become the focus of attention.
  • Feigned blitheness about crises that will predictably attract immediate attention.
  • Others apparently posting on behalf of the individual having identical patterns of writing.

  • The piece gets quite wordy at times (well, it is an academic article) but it’s an interesting insight into a motivations of people who ‘fake sick’ on the internet.

    Synthetic highs are mutating

    A new study on the chemicals in the latest batch of legally sold ‘synthetic highs’ has found what looks like an unintended hybrid drug.

    As regular Mind Hacks readers will know, I’m a keen watcher of the murky ‘legal high’ market.

    We seem to be in the unprecedented position where sophisticated grey-market pharmacologists are rapidly inventing completely new-to-science drugs in underground labs for thrill-seeking punters.

    These synthetic drugs have typically come in two types: ‘fake pot’ – made from synthetic cannabinoids and stimulants, usually derived from cathinone.

    A study just published in Forensic Science International looked at the chemicals in a new wave of ‘fake pot’ herbal highs sold over the internet.

    Firstly, the research identified 12 new synthetic cannabinoids. That’s twelve completely new untested cannabis-like drugs. The turnover in the market is both stunning and scary.

    Curiously though, one ‘legal pot’ sample contained both a new synthetic cannabinoid (identified as URB-754) and a cathinone (4-Me-MABP) in it.

    What was most surprising though, was that these substances had chemically reacted with one another to create a completely new combination drug. It has the chemical name (N,5-dimethyl-N-(1-oxo-1-(p-tolyl)butan-2-yl)-2-(N′-(p-tolyl)ureido)benzamide) if you want to sound sexy.

    In other words, while the makers intended to put both a cannabinoid and a stimulant in the same product, they probably never knew that the substances had chemically combined to produce a hybrid compound with completely unknown properties.

    The legal high market is becoming an informal opt-in drug-testing experiment with paying subjects.

    Hallucinations of the inner body

    One of the least understood symptoms in psychosis are hallucinations called cenesthesias. These are ‘inner body’ feelings that often don’t correspond to any known or even possible bodily experiences.

    A team from Japan has just published a study of patients who experience cenesthesias in the mouth. Here are a selection of the hallucinations:

    “Feels like gas is blowing up in his mouth”, “feels like something is struggling, as if there is an animal in his mouth”

    “Feels the presence of wires in the mandibular incisors [front teeth in the jaw] when removing dentures”

    “Feels something sticky coming up rapidly in her mouth”, “feels like a membrane is covering and squeezing her incisors”

    “Feels like trash is coming up behind her dentures”, “feels sliminess in her mouth”

    “Feels slimy saliva”, “feels like her teeth are made of iron and is sore from chewing”

    The study used a type of brain scanning called SPECT (essentially, injecting your brain with radioactive glucose, seeing where it ends up with a gamma camera) to look at the balance of activity over the two hemispheres when the patients were just resting.

    They found that activity was relatively greater in the right hemisphere, which is a common, but not very reliable finding in psychosis research.

    A memory of shifting sands

    The New York Review of Books has a reflective piece by Oliver Sacks on the swirling mists of memory and how false recall has affected authors and artists throughout history.

    [Science] is startling to realize that some of our most cherished memories may never have happened—or may have happened to someone else. I suspect that many of my enthusiasms and impulses, which seem entirely my own, have arisen from others’ suggestions, which have powerfully influenced me, consciously or unconsciously, and then been forgotten.

    Similarly, while I often give lectures on similar topics, I can never remember, for better or worse, exactly what I said on previous occasions; nor can I bear to look through my earlier notes. Losing conscious memory of what I have said before, and having no text, I discover my themes afresh each time, and they often seem to me brand-new. This type of forgetting may be necessary for a creative or healthy cryptomnesia, one that allows old thoughts to be reassembled, retranscribed, recategorized, given new and fresh implications.

    Sacks reflects on some of his own shift sans of memory and the thin line between ‘literary borrowing’ and unrecognised remembering.

    The dark patch of death

    We’ve covered some dodgy neuroscience journalism in our time but The Daily Mail has such as amazing piece of tosh, I’m not sure if it’s supposed to be serious or the result of huffing bathroom cleaner.

    Where evil lurks: Neurologist discovers ‘dark patch’ inside the brains of killers and rapists

    Hmmm, this sounds like it’s going to be a sensational piece of nonsense. I wonder what the ‘dark patch’ refers to?

    A German neurologist claims to have found the area of the brain where evil lurks in killers, rapists and robbers.

    It’s not looking good. Evil doesn’t ‘lurk’ in any part of the brain.

    Death of a booty chemical

    I’ve got a piece in The Observer about why dopamine isn’t a ‘pleasure chemical’ but how this idea is likely to stay because it’s too useful for the media.

    It provides a simplified explanation for a whole range of behaviours and sexes-up science stories, regardless of whether it makes sense or not.

    If there were a celebrity among brain chemicals, it would be dopamine. Supposedly released whenever we experience something pleasurable, it’s forever linked to salacious stories of sex, drugs and wild partying in the popular press. The Kim Kardashian of neurotransmitters, it gives instant appeal to listless reporting and gives editors an excuse to drop some booty on the science pages.

    There are too many bad examples to mention in detail, but I have some favourites. The Sun declared that “cupcakes could be as addictive as cocaine” because they apparently cause “a surge of the reward chemical dopamine to hit the decision-making area of the brain”. The article was topped off with a picture of Katy Perry, apparently a “cupcake fan” and, presumably, dangerously close to spiralling into a life of frosted-sponge addiction.

    The piece goes on to mention another particularly bad example of dopamine reporting among many and explains why the ‘pleasure chemical’ cliché just doesn’t fit the science.

    Unfortunately, one of my best lines (definition: I laughed at my own joke) got edited out.

    The original line was “It was clearly just a smokescreen for the views of gun and, er, cupcake hating liberals” which has just been edited down to “gun hating liberals”.

    It’ll make sense when you read it.

    Emotions are included

    New Republic has an interesting piece on how corporations enforce ’emotional labour’ in their workforce – checking that they are being sufficiently passionate about their work and caring to their customers.

    It focuses on the UK sandwich chain Pret who send a mystery shopper to each outlet weekly and “If the employee who rings up the sale is appropriately ebullient, then everyone in the shop gets a bonus. If not, nobody does.”

    The concept of ‘emotional labour‘ was invented by sociologist Arlie Hochschild who used it to describe how some professions require people to present as expressing certain emotions regardless of how they feel.

    The idea is that the waiter who smiles and tells you to ‘have a nice day’ doesn’t really feel happy to see you and doesn’t particularly care how your day will go, but he’s asked to present as if he does anyway.

    The idea has now moved on and this particular example is considered ‘surface acting’ or ‘surface emotional labour’ while ‘deep acting’ or ‘deep emotional labour’ is where the person genuinely feels the emotions. A nurse, for example, is required to be genuinely caring during his or her job.

    ‘Surface emotional labour’ is known to be particularly difficult when it conflicts too much with what you really feel. This ’emotional dissonance’ leads to burnout, low mood and poor job satisfaction. In contrast, ‘deep emotional labour’ is linked to higher job satisfaction.

    The New Republic article links to a deleted but still archived list of ‘Pret behaviours’ written by the company to state what is expected of the employees.

    Apart from some classic corporate doublethink (‘Don’t want to see: Uses jargon inappropriately; Pret perfect: Communicates upwards honestly’) you can see how the company is trying to shift their employees from doing ‘surface emotional labour’ to ‘deep emotional labour’.

    For example:

  • Don’t want to see: Does things only for show
  • Want to see: Is enthusiastic
  • Pret perfect! Loves food

  • Cynics would suggest this is a form of corporate indoctrination but you could also see it as part of drive for employee well-being. You say tomato, I say “smell that Sir – wonderful isn’t it? Fresh tomatoes from the hills of Italy”.

    Those of a political bent might notice an echo of Marx’s theory of alienation which suggests that capitalism necessarily turns workers into mechanistic processes that alienate them from their own humanity.

    However, the concept of ‘deep emotional labour’ is really where the approach can start becoming unhelpful as it has the capacity to denigrate genuine compassion as ‘required labour’. I doubt many nurses go into their profession intending to ‘monetize their emotions’ or feel they have been ‘alienated’ from their compassion.

    And as armies are loathe to admit, soldiers serve for their country but fight for their platoon mates. Is this really a form of ‘deep emotional labour’ or it is just another job where emotions are central?

    Violating the prime directive

    The Chronicle of Higher Education has an in-depth article that explores the controversy over social priming, which suggest that our behaviour can be changed by exposing us to certain concepts.

    The most famous study in the genre was led by psychologist John Bargh, who is the focus of the story and who found that people walked more slowly down a corridor after reading words associated with being old.

    A failed replication of this study and the subsequent online reporting led Bargh to get a bit hot under the collar which was the tipping point for growing skepticism concerning social priming.

    The article is a very good account of that, although one drawback is that it doesn’t distinguish very well between ‘priming‘ – an extremely well replicated effect and one of the bedrocks of psychology, and ‘social priming’ – the subtype which is now in doubt.

    The idea behind classic priming is that if you activate a meaning, perhaps just by experiencing it, related meanings will also become activated. This activation will be less strong for less related meanings.

    Because we access meanings that are activated more quickly, you can test effect in reaction time tasks.

    For example, if you see the word ‘apple’ you will subsequently identify the word ‘orange’ more quickly because they are related in meaning. The word ‘aeroplane’, however, will be unaffected. In other words ‘apple’ will prime ‘orange’ but not ‘aeroplane’.

    There are various ways of testing this but it boils down to the fact that in terms of priming meaning, the effect is not at all controversial. It’s extremely reliable and can be seen in many sorts of tasks – verbal, visual, auditory and so on.

    However, social priming suggests that concepts about people or identity (such as being old or being a professor) affect complex behaviours (such as walking speed or test performance).

    Furthermore, several of these experiments have suggested that the meanings can be primed in ways that rely on analogy or metaphor – for example, that people who feel lonely will spend more time in a hot shower as they are primed to need ‘warmth’.

    Many people find some of these effects implausible and, as the article makes clear, the skeptics are now attempting to replicate some of the most well-known experiments to very mixed results.

    If you’ve not been following the wires, when a research team couldn’t replicate Bargh’s study everything kicked off and hangbags were flailed around by Bargh, a Belgian research group, Nature, a Nobel prize winner and the internet.

    Bin your copies of Kuhn people, this is how science really works.
