Does smoking cannabis make people more violent?

The article below summarizes an academic study which claims to show that smoking marijuana causes people to beome more violent.  But I don't think the authors concerned have remotely proved that.  I myself have never smoked anything and I don't intend to so I have no dog in that fight.

I have read a great deal of the studies of the subject and I am reasonably certain that cannabis promotes psychotic delusions --    but violence is another matter.  My experience is that stoned guys are most likely to sit around passively and make profound remarks like: "Wow, man, like wow!"

So what is wrong with the study below?  Mainly the sampling -- or lack of it.  It was a study of patients released from psychiatric hospitals.  Generalizing from very ill people to normals is simply invalid, to put it mildly.

It's a common comment that any correlation between cannabis use and mental illness may simply show that mentally ill people like cannabis.  Mentally ill people are heavy users of tobacco so that is not an unreasonable view.  The patients are simply trying to self-medicate in both cases.

The authors of the current study, however, claim that they can disprove that theory and show that cannabis sends you mad, not the other way around.  But that too is an absurd claim. You can demonstrate cause only by way of a carefully controlled before and after study and that was not done on this occasion. Instead some statistical jiggery pokery was used.  But that finding too is derived from their non-sample so is again overgeneralizing.  The bottom line is that they have no data proving the matter either way.

A final concern is that the authors mainly seem to concern themselves with "skunk" cannabis, which is much stronger than other forms of cannabis and so should be studied separately.  Skunk does indeed appear to be of concern but what is true of it may not be true of all cannabis.  As toxicologists say, the toxicity is in the dose.

The academic article is Persistency of Cannabis Use Predicts Violence following Acute Psychiatric Discharge


Cannabis users are more likely to commit violent crime, pioneering research has shown. It warned those who smoke the drug regularly run an increased risk of using violence against others.

The project is the first to demonstrate that cannabis is not only linked with violent crime but is the cause.

Violent incidents monitored by the study based on the lives of more than 1,100 American psychiatric patients included assaults, attacks with weapons and rapes.

Researchers said that cannabis causes violence and they found no evidence that the link is the other way round – ie that violent people are more likely to use cannabis.

There was no support, they added, for theories put forward by campaigners anxious to free the drug from the taint of links with crime.

The academics said the effect of cannabis use was clear and not diminished by other factors such as patients who were heavy drinkers of alcohol.

The study comes after a series of American states have decriminalised cannabis – despite it being stronger and more potent than the hash smoked by hippies in the Sixties – or made it available for medical use.

The latest study by five researchers from institutes based in Montreal, Canada, examined the lives of 1,136 men and women who were patients at psychiatric hospitals in Missouri, Pittsburgh and Massachusetts.

Records were gathered from interviews carried out every ten weeks for a year after their discharge.

It said patients who were using cannabis at each of these five checks were nearly two-and-a-half times more likely to have turned to violence than those who had not used the drug.

The study pointed to ‘significant findings regarding the adverse effects of cannabis use on violence’.

It found there was a ‘more constant relationship’ between cannabis and violence than between alcohol or cocaine use and violence. The researchers said the link between cannabis and violence was not two-way but ‘uni-directional’.

Contrary to claims that violent people were drawn to use cannabis, researchers found ‘it was cannabis use that predicted future violent behaviour’.

The academics said psychiatrists and medical staff should watch for cannabis users among those who had been in hospital for mental health problems. The team, led by Dr Jules R Dugre, said existing evidence on the links between cannabis and violence was ‘limited’ but their project had ‘clinical and violence risk management implications’.

Kathy Gyngell, a fellow of the Centre for Policy Studies think-tank, welcomed the ‘definitive study’ and called for official action. ‘Government has been seriously negligent,’ she said.

‘Where is the public health campaign on the risks of cannabis? If ministers had any sense they would know that we cannot afford this public health and safety crisis.

‘It must lead the Government to review their community care policy for such potentially violent individuals to better protect the public.’

The study in the journal Frontiers in Psychiatry flies in the face of claims of former drugs tsar Professor David Nutt.

He was sacked by the Labour government in 2009 for opposing the decision to reclassify cannabis from Class C to Class B. Prof Nutt has long argued that alcohol was ‘considerably more dangerous’ than the drug.

More than 20 US states have in recent years legalised cannabis for medical purposes.

Four – Colorado, Alaska, Oregon and Washington – have allowed its recreational use.

After the relaxation in 2012 in Colorado, cannabis use by students aged 12 to 18 has become the highest in the country. Figures show 57 per cent tested positive in high school tests.

The media is missing the Republican takeover in New England

In this part of the US, people are rooting for Trump more than ever

On Sept. 19, Politico congressional reporter Burgess Everett tweeted that he suddenly “[Remembers Vermont has a Republican governor].” His tweet prompted Seung Min Kim, a fellow Politico reporter who covers the US Senate, to reply that she “[Learns Vermont has a Republican governor].” That, in turn, instigated a response by Wall Street Journal congressional reporter Byron Tau: “[Googles the name of Vermont’s Republican governor].”

To which Phil Scott, Vermont’s Republican governor, responded that he “[Is Vermont’s Republican governor].”

The moment was comical but also insightful, underscoring just how little Washington’s political class knows about who holds the executive power in the Northeast.

Here’s the surprising truth: It’s not the Democrats.

Last November, while most of the country was either cheering Donald Trump’s presidential win or making an appointment with their therapist about how to cope with the results, New Englanders in four out of the region’s six “blue” states — Vermont, New Hampshire, Massachusetts and Maine — woke up the next morning with four Republican governors.

Two of those governorships flipped from blue to red. It was a trend that the Northeast had not seen for a generation, but it received little national attention. (Connecticut and Rhode Island hold their governorship elections in 2018.)

If the reverse had happened, and four Democrats had won governorships in deep red states last year, the news would have been treated quite differently, said Brad Todd, a Washington, DC-based GOP strategist.

“It would have been on the front pages of every major newspaper in the country. And debated for weeks about how it spells the demise of the Republican Party,” Todd said.

Vermont’s Scott won in a landslide, defeating his Democratic opponent by 9 percentage points while facing two political fronts that should have knocked him out of contention: the candidacy of Trump, who was so unpopular in Vermont, he got crushed there by 29 percentage points; and the popularity of Democratic presidential candidate Bernie Sanders, Vermont’s sitting US senator.

Interestingly, if you drove through Vermont last year, it was not uncommon to see yard signs for both Scott and Sanders in the same yards.

Meanwhile, on a trip to Cambridge, Mass., last month, I couldn’t find anyone who didn’t approve of their Republican Gov. Charlie Baker. From the leafy halls of Harvard to locals grabbing lunch at Charlie’s Kitchen on Eliot Street, everyone I talked to was a Democrat — and everyone gave him high marks as the state’s manager.

It’s not just anecdotal. Polling has consistently shown Baker is the most popular governor in the country; the most recent survey done by Morning Consult in July showed that 71 percent of Massachusetts voters are happy with the job he is doing. Meanwhile, Republican Chris Sununu holds New Hampshire’s governor’s office, while Maine has voted for Paul LePage twice to hold their executive’s suite.

The Republican Party is the only party that is a national party.

In the aftermath of the 2016 electoral — but not popular-vote — win of Trump over Hillary Clinton, Democrats have spent endless time bemoaning their inability to capture the Electoral College. They blame it on a so-called antiquated system that gives greater weight to the states populated by more cows than people. But it really is a symptom of a bigger problem for the Democrats: The Republican Party is the only party that is a national party.

Republicans, at some level, are competing in every state up and down the ballot, while Democrats are not competing anywhere but on the coasts and in the big cities. In short, they are a regionalized party, confined to the most densely populated parts of the nation — more cut off and compartmentalized than the GOP.

But if you read reports by national political reporters, you would assume that progressivism dominates the country’s landscape. “The decision makers, who are close to culture and news, live in places where the Democratic Party’s last bastions are, encased in a bubble that believes everyone thinks like they do and votes like they do,” said Todd.

“Those noncompetitive deep-blue places are the only places they have left where they dominate, but it also happens to be the only places where cultural and media institutions are headquartered,” he added.

Seven years after the Republicans won the House and three years after they gained the US Senate majority, the media/entertainment complex still fails to accept or understand that the majority of this country is center-right. Until these institutions grasp this fact, they will continue to see their viewership drop and their trust erode.

There is a reason this year’s Trump-bashing Emmy Awards saw viewership figures tank for the second year in a row (11.38 million views — down 5 percent from 2015). You can’t expect to hold onto the middle of the country when you spend four hours mocking the choice many of them made for president.

And you can’t expect anyone to trust your sense of judgment and fairness if you treat a GOP winning streak in the Northeast as if it never happened.
