Why John Rentoul is wrong about cannabis

The illegality of drugs causes vastly more misery than the use of drugs.

John Rentoul has an interesting piece in today’s Independent in which he councils against the legalisation of marijuana.

His premise is a straightforward one: if marijuana is made legal then more people will invariably use it, which is bad, and the fewer individuals that use drugs the better.

First of all I’d like to agree with John on something before I challenge his broader point. There is, as he points out, some evidence that cannabis is harmful – especially to teenagers with their still-developing brains.

“One, is cannabis harmful? Mostly, no. Mostly, its effect is to make people boring. But it is possible that, in some cases, it acts as a trigger for serious mental illness, especially for male teenagers,” he writes.

I think one might even go further than this. I think there is quite a lot of evidence suggesting a link between heavy cannabis use among teenagers and mental health problems, particularly schizophrenia. I remember being convinced of this even before much of the recent evidence emerged – one of my best friends from school, a heavy cannabis user, was Sectioned at 17 and has been in and out of ‘sheltered’ accommodation ever since.

A few years after leaving school I remember hearing of several others in my extended peer group who were experiencing mental health issues – all of whom heavy cannabis users.

This is anecdotal evidence to be sure, but as I said, there is an increasing body of evidence linking teenage cannabis use with mental health problems.

That said, I must take issue with John’s assertion that legalising cannabis would result in more people using it.

Portugal, a country which moved in 2001 to abolish all penalties for the personal possession of drugs, has seen drug use among teens decline. Rates of new HIV infections caused by sharing of dirty needles has also dropped significantly. The number of people seeking treatment for drug addiction has more than doubled in the five years after decriminalisation. Proportionally, more Americans have tried cocaine than Portuguese have tried marijuana.

Similar evidence can be found in the Netherlands, where citizens have been permitted to buy marijuana for over 20 years. A comprehensive 2004 study found that, for most age groups, marijuana use as a percentage of the population is similar to that seen in the United States. For young adolescents, however, rates of marijuana use were lower in the Netherlands.

Rentoul continues:

“The idea that the existing policy on drugs in this country, and almost everywhere in the world apart from Colorado and Uruguay, is a self-evident failure is not a truth that is self-evident to me.”

Well the Global Commission on Drug Policy, which presumably knows a bit about the effects of prohibition, released a report in 2010 which argued that the global war on drugs has resulted in ‘devastating consequences for individuals and societies around the world’.

The US government spent over $15bn dollars in the same year on its persecution of the illegal drugs trade, at a rate of around $500 per second – surely money which might be spent elsewhere. Around 90 per cent of all cocaine consumed in the US comes via Mexico – a place where, between 2006 and 2012, over 47,000 people were killed in President Philip Calderon’s violent battle with the drug cartels.

As Christopher Hitchens once remarked, “I’m not threatened physically at all if someone wants to put a substance into their system…what does threaten me is the people who will shoot at each other in the street for the right to sell him that stuff.”

The illegality of drugs (and the criminal activity which is funded by drugs) causes vastly more misery than the use of drugs. This may, in most instances, relate to the sale of hard drugs; but the purchase of cannabis often helps put money into the hands of the criminals who deal in the harder drugs – and who are often involved in other, even more serious criminal activity.

And what about the straightforward argument for freedom? If someone wants to put a substance into their system, then why should it be any of the government’s concern?

There is certainly a case for keeping cannabis away from teenagers; but prohibition can have the opposite effect, and can lead to further experimentation with harder drugs. As a young person, finding out than one illegal drug is really not the big deal it is made out to be breeds mistrust in drug warnings and laws in general, and as a result can lead to further experimentation.

This is just one consequence of policy based not on evidence, but on a puritanical attempt to decide for other people what they should be allowed to put into their bodies.

There is a market for drugs, there always has been a market for drugs, and we already recognise as much for (some) drugs, such as alcohol and tobacco. Why not, then, go a bit further and acknowledge as much for other recreational drugs, and reduce the bloodshed by taking the supply out of the hands of the criminals?

    Good article, and I think legalization of cannabis is, for the reasons you give, probably sensible. One point though about the straighforwardness of ‘the argument for freedom’. A government is legitimately concerned about what its citizens put in their bodies. For example, using substances that elicit violent behaviour, or that are likely to lead to problematic addictions can clearly be social problems which affect not only the individual, but also those around him or her and the society more broadly. That there is a principle of full freedom of substance use is dubious – the principle is reactive to the substance and its likely effects. Government intervention is justified insofar as it has the intention of preventing people from harming others (Mill’s harm principle), making the libertarian argument for drug use rather misleading.

    Good article.

    First, your aquaintances who suffered mental health problems and used cannabis: You cannot assume a connection, that’s obvious fallacious thinking. Even if there is a connection it may even be the case that their mental health issues drew them to the drug use. Second, the best research suggests that the kind of harm you imply are quite rare compared with the real damage caused by prohibition, as you demonstrate.

    The simple point is that policy should be about trying to do the least harm. Many countries have cottoned to this and are developing sensible drugs policies. Sadly they are being held back by the boneheaded attitude of the US and its insistence on maintaining current UN treaties on drugs.

    John Rentoul is a notorious fool when it comes to drugs policy. He’s scientifically illiterate and a stranger to common sense. This is what he wrote in June 2012:

    “It is a bad thing that the drugs business is in the hands of criminals. My view is that it would
    be a worse thing if it were legalised, and regulated or administered by the government.”

    I wonder, in the history of journalism on drugs policy, even including Peter Hitchens, has there ever been a more stupid statement?

    Cannabis does not cause schizophrenia. It can exacerbate the symptoms of someone with schizophrenia, however despite this many schizophrenics find cannabis more helpful and less side effects than their prescribed medication.

    Any drug can cause mental health problems the most common one being alcohol. You did not say whether your friends used cannabis exclusively or with other drugs including alcohol. Otherwise a good article.

    However….all political parties are afraid of the Daily Mail and the Daily Mail lies constantly on this topic. Alternatively one could just accept that that this government (and the last one too) simply don’t like personal liberty and/or that they don’t like people with MS/Migraine/ME/insomnia/chemotherapy reactions/glaucoma and a host of other ailments, but that they DO like the company that makes Sativex which is cannabis oil in a spray, so they have selected that company to have the privilege of a lucrative monopoly despite repeating the claim that cannabis has no medical application….and of course Gordon Brown and David Cameron are trustworthy guys who know a great deal about medicine. Thankfully we have no need for a bill of rights that could p[protect us against arbitrary, cruel, stupid and dishonest actions by the state because the state is always right.
    Yippee……

    The key point is this: recent publications (see Sanjay Gupta’s mea culpa last year) say quite clearly that heavy (having looked at the numbers, I’d argue *very* heavy, actually) marijuana use between 14 and 19 can in some individuals produce the *symptoms of* paranoid schizophrenia. However, *all symptoms disappear within three weeks*; there is zero evidence of permanent functional impairment, let alone causing or triggering actual schizophrenia. Anyone the OP knows who suffered symptoms independently of their marijuana habit, e.g. while sectioned and therefore not ingesting, was a schizophrenic independently of marijuana.

    John Rentoul with this piece of work has sown the wind whilst having no appetite at all for the whirlwind.

    Re: “heavy cannabis use and mental health problems”– James might have gotten it right had he bothered to define “heavy” use– it means rolling a 500-mg H-ot B-urning O-verdose M-onoxide “joint” (giant) every time you want “a smoke”– and guess what, there’s a picture of one right there heading his article!
    Please consider the following alternative: a VAPORISER or, failing the money, you can make your own Long-Drawtube One-Hitter permitting 25-mg single tokes. Give it a try and let young and old do likewise, and see if “mental problems” don’t reduce drastically (along with $igarette smoking etc.”).

    i have always wondered what it must be like for a medical student learning their proffession, probably quitely thinking to themselves i need to get my practices right primarilly for the patient,then also for myself,so that i can carry on with my career succesully! i can only think it must of been an espeically difficult practice to keep intrested in ,since about from lets say the1950s until 2000,,this scenario was probably seen for now,that when a patient is delivered to a mental health hospital primarily for assement, i presume,that the patient is asked what has he taken in to his body recently truthfully ya know somewhere to start thing.,and he/she replies truthfully i have been drinking a combinationation of alcohol and smoking a combination of cigarrettes and the flowering head of the cannabis plant ya know weed,ganja,pot a spliff doc the medical student would probably make a decision for treatment based on their knowledge, then maybe more than likely consult a senior for guidence or seek knowledge from medical books,then have to deal with the situation of ah we know the effects of alchohol,its legal and we have been able to study it we know what ito do!great cigarettes yep legal too we have reseach to back up treatment great now then cannabis plant oh illegal no upto date reseach availible oh bugger i will have to guess!
    I can only guess that all those opposed to the illegalizaion of the cannabis plant have played a very important part to the treatment and the labelling of conditions for patients fpr years,………could it be true?
