The Brief

Could smoking pot lead people to drink less alcohol?

In an elaborate and provocative experiment, scientists doled out joints and free drinks to see whether this idea — sometimes described as "California sober" — survived scientific scrutiny.

The new research offers some of the strongest data yet suggesting that smoking weed does, at least in the short term, curb how much people drink.

The findings were published in the American Journal of Psychiatry on Wednesday — and are sure to raise questions about the merits of swapping one of these substances for another, especially given growing concern in the public health field about the popularity of cannabis.

And the researchers are cautious about making any recommendations based on their findings at this point.

"We're not ready to tell people seeking treatment for alcohol, go ahead and substitute cannabis, and it will work out for you," says Jane Metrik, a professor of behavioral and social science at Brown University who led the study.

But the research does bring scientists closer to understanding the link between these two substances, at a time when many people are leaning on marijuana to cut back on drinking, without waiting for the evidence.

"This study really moves the field forward by helping to resolve one of the unresolved questions in the literature," says Jeff Wardell, a professor of psychology at York University. "This gives us more confidence that there's a real effect here."

Getting high for science

In the Brown study, the team took pains to replicate the real-life circumstances of getting stoned and drinking, while still maintaining a tightly controlled study that could point toward a causal relationship.

They constructed a laboratory that resembles a bar, with comfy seats and a tap, and ensured each participant had their preferred alcoholic beverage on hand.

"We wanted to make sure that when given the opportunity, you would be really driven to drink," says Metrik, who ended up spending substantial time shuttling between liquor stores looking for special vintages and spirits.

The experiment included three separate sessions. In one of them, participants smoked a marijuana joint with higher levels of the psychoactive compound, THC; in another they used a lower potency strain; and the last, researchers gave them a placebo with a trace amount of THC that wasn't enough to get them high.

After toking up in a designated smoking room, each participant spent the next two hours in the "bar lab" on their own where they had the opportunity to drink up to eight mini drinks.

The people who smoked the higher potency cannabis ended up drinking 27% less alcohol, and the lower potency about 19% less, compared to the placebo. People who used cannabis also delayed their drinking.

"It is an important signal that we're detecting," says Metrik. "It is telling us that cannabinoids could play a potential therapeutic role in alcohol use disorder."

Previous research has suggested that cannabis may reduce alcohol cravings and how much people drink. But the results have been largely inconclusive, in part because the data often come from observational studies, which are less reliable and can be muddied by other factors. Animal studies have also indicated potential biological mechanisms behind weed's effect on alcohol; however, there's a question of how much this applies to humans.

The new study also builds on what a team of researchers in Colorado reported earlier this year in a slightly different experiment.

There, participants instead picked up their marijuana from a dispensary, smoked it at home and then visited a mobile lab parked nearby, where they were offered alcoholic beverages.

The amount people ended up drinking dropped by about 25% when they were already stoned. Cravings also went down.

"These findings are all converging on a similar story," says Hollis Karoly, an associate professor of psychiatry at the University of Colorado Anschutz who led the study. But she points out there are still big questions about how much you can extrapolate from this new evidence.

Replacing one problem with another?

One obvious limitation is that how someone behaves when every sip they are taking is under close observation may not necessarily reflect what happens in a much looser, real-world social setting.

And beyond that, Karoly says this pattern toward reduced alcohol consumption wasn't true for everyone in their study. In a minority of people, it actually led them to drink more.

"This really highlights the fact that individual differences matter," she says.

Another unanswered question centers on who's being studied.

Most of the people in the Brown trial met the criteria for "cannabis use disorder," and about 40% for alcohol use disorder. That could indicate their "drug of choice" was not necessarily alcohol in the first place, says Rajita Sinha, a professor of psychiatry at Yale University.

For people with problem drinking, cannabis might be a potential treatment, she says. This approach, on the other hand, "may also be promoting more cannabis use and that would be problematic."

"Once you're in the throes of daily cannabis use, it's very hard to kick that habit," she says.

Those involved in this work acknowledge the tension in this line of research.

Cannabis doesn't carry the same risks of extreme harm as alcohol, which is a leading cause of preventable death in the U.S and kills more than 170,000 people a year.

But Wardell says cannabis is clearly "not a harm-free substance," either.

While research on its effect has not kept up with its surging popularity, studies have shown marijuana can impair cognition and memory, trigger a serious gastrointestinal syndrome that causes nausea and vomiting, increase the risk of psychosis and other psychiatric illness, and impact relationships and social functioning.

And Wardell says this latest study doesn't actually tell us whether the negative outcomes of alcohol are worse than cannabis in the long run.

"We would have to choose which one for a given individual might be less harmful and make sure that it's not inadvertently just replacing one problem with another," he says.

In her role as a clinical psychologist, Metrik at Brown has seen some patients with severe alcoholism who successfully stopped drinking with the help of cannabis, though some have then gone on to develop issues with that drug.

In her mind, the problem right now is that many people are relying on cannabis to treat their alcohol problems, without any guidance.

"We see this all the time, and we don't know what to tell them," she says. "There's no clear messaging,"

Lines stretched around the block Sunday at the Original Saugus Cafe in Santa Clarita. It was supposed to be the restaurant's last day before closing after 139 years — making it the oldest continually operated restaurant in Los Angeles County.

But earlier this week, a sign was posted on the door saying, "Reopening under new ownership soon," although there were few details about who would be running it.

The sign was a surprise to the Mercado family, who have operated the restaurant for nearly 30 years. The family now is in a legal dispute with the Arklin family, who owns the property, about the potential re-opening and who owns the historic name.

The background

Alfredo Mercado worked his way up from bartender to restaurateur, purchasing the business in 1998. Since then Mercado and his daughters have operated the restaurant, leasing from the Arklin family. For most of that time, according to the Mercado side, the two families maintained good terms. Property owner Hank Arklin Sr., a former state assemblyman who owned other properties in the area, kept a verbal month-to-month agreement with the Mercados — no written lease required.

That changed when Arklin died in August at age 97.

New terms, failed negotiations

Larry Goodman, who manages multiple properties for the Arklin family's company, North Valley Construction, took over the landlord relationship. In September, the Mercado family say they were presented with a new written month-to-month lease.

Yecenia Ponce, Alfredo's daughter, said the new terms included various changes to the existing agreement, including a rent increase and charges for equipment.

Months of back and forth negotiations about different options, including selling the business, ultimately fell apart. Their attorney, Steffanie Stelnick, says they are being forced out, without proper legal notice, and has sent a cease-and-desist letter to Goodman saying the family has plans to continue running the business.

LAist reached out to Goodman for comment repeatedly Wednesday and Thursday by phone but did not hear back.

Goodman told The Signal, a Santa Clarita valley news outlet, that Alfredo Mercado had changed his mind several times in recent weeks about keeping the business.

“I said, ‘Fine,’ then I got out and got someone to take it over,” Goodman said.

He said he'd been in contact with Eduardo Reyna, the CEO of Dario's, a local Santa Clarita restaurant, and that the cafe could re-open as soon as Jan. 16.

Who owns what?

The dispute also focuses on who owns the rights to the Original Saugus Cafe name.

Ponce said when her father purchased the restaurant in 1998, it was called The Olde Saugus Cafe, but the name was then changed to The Original Saugus Cafe. State records show that name registered as an LLC under Alfredo Mercado.

After Arklin’s death, however, the Arklin family filed a pending trademark application to lay its own claim to the name.

The Mercado family is resisting.

"As long as they don't buy the name from us, we're not handing it over," Ponce said.

Ponce said the family had no idea the landlord planned to continue operations.

"We truly did think we were closing," she said. "We were not aware that they had plans to continue."

She apologized to customers for the confusion.

Whether the decades-old restaurant name survives — and under whose control — may ultimately be decided in court.

Community leaders and politicians in Los Angeles are responding in outrage after an ICE agent shot and killed a woman in Minnesota on Wednesday.

The fatal ICE shooting of 37-year-old Renee Good has sparked anger and fear in Los Angeles, which has been an epicenter of federal immigration enforcement since the summer.

Jorge-Mario Cabrera with the Coalition for Humane Immigrant Rights, or CHIRLA, says the killing was upsetting but not surprising.

" Los Angeles has been witness of the escalating aggressiveness of these federal agents against the community," he told LAist.

Homeland Security Secretary Kristi Noem has defended the shooting, saying Good was trying to run agents over with her car. That account has been disputed by eyewitnesses, the mayor of Minneapolis and other officials. Bystander video also challenges the federal narrative, according to MPR News.

L.A. politicians have joined a chorus demanding justice for Good. Mayor Karen Bass posted on X, saying that ICE agents are waging "a purposeful campaign of fear and intimidation" on American cities.

"The senseless killing of an innocent and unarmed wife and mother by ICE agents today in Minneapolis is shocking and tragic and should never have occurred," she said in the post.

L.A. County Supervisor Janice Hahn called on Noem to withdraw ICE from U.S. cities.

“These ICE agents are undertrained and trigger happy and everyone who has seen this video knows ICE murdered this woman,” she said in a statement.

Some protesters also gathered outside the federal building in downtown L.A. Thursday morning to condemn the killing.
