Can party drug MDMA help treat alcoholism?

A pioneering new study in Bristol is using MDMAassist­ed psychother­apy to help alcoholics break the cycle of addiction

- WORDS: RUSSELL DEEKS

A groundbrea­king study in Bristol is using MDMA to help recovering alcoholics in therapy open up about their troubled pasts.

Alcohol is dangerous. Its abuse accounts for around 8,000 deaths in the UK every year, while the societal cost – in terms of the strain on the NHS and the police – is enormous. It costs £3.5bn a year for the NHS to treat alcohol-related illnesses and injuries, while 70 per cent of violent incidents occurring during the evenings, nights and weekends involve alcohol.

Many people are, of course, able to enjoy a drink without coming to any harm, or becoming addicted. But many aren’t: it’s estimated that 9 per cent of men and 3 per cent of women in the UK show signs of alcohol dependence. And if you do get hooked, the prospects aren’t great.

There are many treatment programmes available, but over 80 per cent of people that complete one will be drinking dependentl­y again within four years – and the dropout rate is also high, so the majority of those who seek help won’t even complete a treatment programme in the first place.

But a groundbrea­king study currently underway in Bristol may offer new hope. The project is exploring the use of MDMA – 3,4-methylened­ioxy-methamphet­amine, or ‘ecstasy’ – as an adjunct to psychother­apy, to help addicts come to terms with childhood trauma such as neglect or abuse.

Previous studies in the US have shown that, used in this way, MDMA can be beneficial in treating people living with post-traumatic stress disorder (PTSD). Now the Bristol team, overseen by Prof David Nutt at Imperial College London – the former government drugs advisor who, in 2007, was dismissed from his post on the Advisory Council on the Misuse of Drugs after calling for a more evidence-based approach to drugs policy – wants to see if they can achieve similar results working with alcoholics.

PART OF THE PROCESS

Let’s be clear about one thing: MDMA is not a cure for alcoholism and it’s not simply a case of giving patients a bag of pills and they’ll forswear the booze overnight. Instead, the Bristol study sees psychiatri­st Dr Ben Sessa and clinical psychologi­st Dr Laurie Higbed researchin­g MDMA as part of a programme of intensive psychother­apy, which is only embarked upon after participan­ts have undergone a detox programme to cure their physical dependency. Sessa and 2

2 Higbed’s programme is aimed at addressing the reasons that drove the patients to alcohol misuse and addiction in the first place.

“I did my initial training in child and adolescent psychiatry. I spent 10 years working in an inpatient unit and came across many young people with developing personalit­y disorders. All of them abused, maltreated as children, carrying around a head full of traumatic memories. Many self-harm, some take their own lives before reaching adulthood and many end up dependent on drugs and alcohol,” explains Sessa. “Current treatments for these disorders are very poor. Most psychiatri­c medication­s just paper over the cracks. It’s like taking paracetamo­l if you’ve got a fever – it’ll bring your temperatur­e down, but it’s not going to kill the bug. In psychiatry, the bug is trauma and the only real cure is psychother­apy.”

Many people therefore find themselves turning to drugs and alcohol, which are highly effective at blocking out the pain in the short-term but bring all kinds of new problems with them. But MDMA can help people open up and talk about their most deep-seated problems, so Sessa wants it to be used in conjunctio­n with psychother­apy to provide a better treatment.

TESTING ENVIRONMEN­TS

MDMA was first produced and patented in 1912 by German company Merck Pharmaceut­icals in an effort to develop an artificial blood-clotting agent. According to records in the Merck archive, the drug was administer­ed to patients in a Berlin hospital but it took until 1927 for someone to notice the similarity between its chemical structure and that of the hormone adrenaline. That’s when the first animal trials were conducted to see if MDMA might mimic the hormone’s effect.

Then in the 1950s, a US chemist called Alexander Shulgin discovered the compound and began to experiment with it as a tool in relationsh­ip counsellin­g, which remained its primary use until the early 1980s. But by that point, enough of the substance had leaked out from labs and clinics to be used recreation­ally that the US government decided to ban MDMA in 1985, putting paid to any genuine research that was being carried out (it had been classified as a class A substance in the UK since 1977).

It’s illegality didn’t prevent the rave explosion of the late 1980s and early 1990s from taking the drug into the mainstream, however, which is something Sessa isn’t entirely happy about. “I see MDMA as a medical tool, and the rave generation as an irritating blip in its history,” he explains. “MDMA is a medical compound.

"MOST PSYCHIATRI­C MEDICATION­S JUST PAPER OVER THE CRACKS"

It started in medicine, it was useful and we were making some great strides. It then stopped for 30 years, but now we’re bringing it back into the clinic, where it belongs. Because from a pharmacolo­gical perspectiv­e, MDMA is a remarkable compound that works across a number of different receptors.”

MDMA works because it acts upon serotonin receptors in the brain. It increases the levels of serotonin – the ‘happy’ neurotrans­mitter – to create the drug’s wellknown ecstatic or euphoric effects. At the same time, it activates other receptors to provide a mild psychedeli­c effect – not enough to make the walls seem like they’re melting, in the way that LSD and DMT do, but enough to boost the user’s creative thinking and open their mind to new possibilit­ies.

Paradoxica­lly, MDMA also affects the brain’s noradrenal­ine and dopamine receptors, which means it has an amphetamin­e-like stimulant effect while simultaneo­usly inducing feelings of relaxation – this is why ecstasy users often talk about feeling ‘fuzzy’ or ‘fluffy’. It also boosts the brain’s production of oxytocin – the bonding hormone that breastfeed­ing releases in the brains of new mothers.

A SAFE SPACE

Essentiall­y, MDMA mutes the fear response while keeping the other cognitive faculties intact. It’s this, says Sessa, that makes the drug such a powerful therapeuti­c tool. “In some cases, we’re working with people who’ve never experience­d a positive mood before,” he explains. “They’ve been living with fear and pain for their entire lives, but now they have this MDMA experience, and they feel good. They feel warm, safe, serene.

“Now a cynic would say, ‘But that’s a drug-induced experience: it’s transient, it’s not real.’ Which is true, but it’s still a valuable experience for someone who’s never had peace in their lives. For six hours, they’ve got peace, and yes it’s a transient, drug-induced peace, but that’s a useful platform because while they’re in that positive mood you can do a lot of good work.”

Participan­ts for the Bristol study are recruited from clients of Addaction, a national addiction and recovery service with a base in Weston-super-Mare. They must not be addicted to any other substance 2

2 (other than caffeine and nicotine) and they must not have taken MDMA in the past six months, or more than 20 times in their lives. There is also a series of tests to weed out anyone who may have other conditions, such as a weak heart or certain psychiatri­c disorders, that make MDMA use inadvisabl­e.

Once patients have been accepted and have detoxed (either by gradually reducing consumptio­n over several months or after a tapered programme of benzodiaze­pines over a period of 7-10 days to counter the potentiall­y fatal effects of alcohol withdrawal) they commence their psychother­apy with Sessa and Higbed. The programme involves 10 psychother­apy sessions over eight weeks – only two of which are MDMA-enhanced. There are then follow-up sessions at three, six and nine months.

The MDMA sessions take all day, with patients given a dose of MDMA, followed by a second, smaller dose two hours later. The sessions take place in the Sleep Studies suite at St Michael’s Hospital in Bristol, which is specially re-dressed for the occasion with soft lighting, throws on the bed and rugs on the floor to create a less intimidati­ng environmen­t. Participan­ts lie on the bed with the two therapists either side of them and don an eyemask and headphones through which a playlist of ambient music specially curated to reflect the peaks and troughs of the MDMA experience is played. And then the talking starts.

“The patients aren’t just lying there in ecstasy, saying ‘I love everything’,” Sessa is keen to point out. “We’re asking them to go to some dark places and to do some very difficult work. But with MDMA, its selective inhibition of the fear response has an extraordin­ary effect and when we ask about their childhood, they’re amazed at their own ability. They say things like, ‘My God, I can actually tell you all about it’. The MDMA provides a kind of life-jacket that protects you from the fear and allows you to do the psychother­apy. You’ve spent 20, 30, 40 years avoiding these memories, but with MDMA you can go there and talk about it.”

Alternativ­ely, some patients may not talk at all – and that’s okay, says Higbed. “We trust the process and know that they’re having an internal experience. That’s why the patients stay overnight, and why we have another session the next morning before we send them home, where we talk about their experience and help them to integrate it into their lives.”

RISK VS REWARD

Eyebrows are inevitably raised whenever the use of illegal drugs is discussed. Some question whether MDMA treatment could lead to a new addiction, while others may ask how safe the whole process is.

Sessa is sanguine on both counts. “The risk of addiction is staggering­ly low,” he says. Approximat­ely 600,000 people took ecstasy each year between 20002015, according to figures from the Crime Survey for England and Wales, “but MDMA dependency is still as rare as hen’s teeth,” says Sessa. “I’ve only heard of one case. Ask any psychiatri­st if they have any MDMA addicts on their wards, and they’ll tell you it’s just not on the radar.” According to Sessa, there have been some 1,600 MDMA sessions given clinically over the past 10 to 15 years and not one single case of dependence has been reported. Mephedrone, meanwhile, appeared as a recreation­al drug around 2007, and although experts say more evidence is needed to determine if it can cause addiction, a small-scale survey of users in 2011 suggested 30 per cent of them showed signs of dependence.

“As for safety, no medical interventi­on is ever totally risk-free,” says Sessa. “As doctors we don’t use abstract terms like ‘safe’ or ‘dangerous’. We ask: ‘Is this interventi­on justified in this particular person at this particular time? Does it come down on the side of

benefits and can we keep risk to a minimum?’ That’s the same whether we’re sticking on a plaster or removing your bowel. And when you put MDMA through that analysis – here’s a patient who’s experience­d childhood trauma, who has 20 years of alcoholism, who’s had all kinds of medication, who’s been in and out of hospital, been sectioned, attempted suicide… can we justify a controlled dose of MDMA in a clinical situation? It’s an absolute no-brainer. The risk is very, very small compared to the enormous benefits.”

THE ROAD AHEAD

Sessa explains that in rare cases you can get a negative reaction, but they do a lot of physiologi­cal screening to avoid that. Plus, all patients have blood tests and an ECG, and are screened for certain mental problems. While the MDMA experience is taking place, the patients are monitored and their blood pressure and temperatur­e is recorded every half hour, to minimise risk.

Still, these are early days and Higbed says that we are still a long way from treatment. The work being carried out in Bristol involves fewer than 20 patients, and is what’s known as an ‘open-label, proof of concept, safety and tolerabili­ty study’. This means that everyone knows they’re receiving MDMA, and the real test is to see if this applicatio­n of the drug has any negative effects. If none are apparent, then Sessa and Higbed hope to get funding for a full-scale, double-blind, placebo-controlled study. And both are hopeful. “When I first got involved with this project, I read about the Mithoefer study from 2010, where Michael and Annie Mithoefer in the US used MDMA-assisted psychother­apy to treat Vietnam War veterans with chronic PTSD,” says Higbed. “After 12 weeks they were free of symptoms and they maintained that over three, six and nine months. That’s pretty much unheard of. Now in our study, we’ve got two patients coming up to their six-month follow-ups and one coming up to three months, and so far two of them haven’t picked up a drink at all, and one’s only had a single drink on a couple of occasions. That’s already a better success rate than many other programmes.”

Longer term, Sessa imagines a future where MDMA therapy will be available on the NHS. “It’ll never be a take-home drug. But MDMA is on course to be A-approved by the European Medicines Agency in 2021, and after that you should be able to get this treatment legally, on the NHS, delivered through MDMA therapy centres. And the one we’re setting up in Bristol will be the first.”
