If More Couples Smoked Weed, Would There Be Less Domestic Violence?

Spouses who smoke weed are less likely to inflict physical, sexual, or psychological harm on their significant other.

Stoner couples fight less, according to a new University at Buffalo study that investigates the relationship between marijuana use and intimate partner violence. The researchers surveyed 634 couples that applied for a marriage license in Buffalo, NY, between 1996 and 1999, throughout the first nine years of their marriages. Couples in which both spouses reported “frequently” using marijuana also reported the least amount of domestic violence.

But the study’s conclusions come with some caveats: While the research solely hones in on newly married, heterosexual couples in Buffalo, intimate partner violence is a far-reaching issue that affects a wider demographic than those who have recently tied the knot. It still remains unclear whether remarried, long-married, dating, or same-sex couples who smoke pot are similarly less violent than their abstaining peers, or whether there’s just something particularly peaceful about Buffalo bud.

Nonetheless, the study breaks new ground in exploring the causes behind an issue that, according to a 2012 report by the Bureau of Justice Statistics, affected Americans at a rate of 3.6 victimizations per 1,000 people in 2010. Previous research has shown that alcohol use strongly predicts domestic violence, and that substance use often follows as a result of that violence, but the University at Buffalo team is the first to attempt to quantify over time the specific impact of marijuana use on this kind of physical aggression.

It’s an interesting and important inquiry, as states continue to legalize marijuana for reasons both medical and non-medical. Public support for marijuana legalization in the U.S. famously reached a majority last year, an increase of 33 percent since 1995. Is it a coincidence that in roughly that same period, according to that same Bureau of Justice Statistics report, domestic violence in America has declined by 64 percent?


When former Pittsburgh Steelers' center Mike Webster committed suicide in 2002, his death began to raise awareness of the brain damage experienced by NFL football players. A 2017 study found that 99% of deceased NFL players had a degenerative brain disease known as CTE (chronic traumatic encephalopathy). Only one out of 111 former football players had no sign of CTE. It turns out, some of the risks of traumatic brain injury experienced by heavily padded adults playing at a professional level also exist for kids with developing brains playing at a recreational level. The dangers might not be as intense as what the adults go through, but it can have some major life-long consequences.

A new PSA put out by the Concussion Legacy Foundation raises awareness of the dangers of tackle football on developing brains, comparing it to smoking. "Tackle football is like smoking. The younger I start, the longer I am exposed to danger. You wouldn't let me smoke. When should I start tackling?" a child's voice can be heard saying in the PSA as a mother lights up a cigarette for her young son.

On Tuesday morning, President Trump tweeted about some favorable economic numbers, claiming that annual household income is up, unemployment is low, and housing prices are high.

Now, just imagine how much better those numbers would be if the country wasn't mired in an economy-killing trade war with China, bleeding out trillion-dollar-a-year debts, and didn't suffer from chaotic leadership in the Oval Office?

At the end of tweet, came an odd sentence, "Impeach the Pres."

October is domestic violence awareness month and when most people think of domestic violence, they imagine mostly female victims. However, abuse of men happens as well – in both heterosexual and homosexual relationships. But some are taking it upon themselves to change all that.

At this point most reasonable people agree that climate change is a serious problem. And while a lot of good people are working on solutions, and we're all chipping in by using fewer plastic bags, it's also helpful to understand where the leading causes of the issue stem from. The list of 20 leading emitters of carbon dioxide by The Guardian newspaper does just that.

Before the release of "The Joker" there was a glut of stories in the media about the film's potential to incite violence.

The FBI issued a warning, saying the film may inspire violence from a group known as the Clowncels, a subgroup of the involuntarily celibate or Incel community.

Incels an online subculture who believe they are unable to attract a sexual partner. The American nonprofit Southern Poverty Law Center describes them as "part of the online male supremacist ecosystem" that is included in its list of hate groups.
