A new study from University of Toronto public health researchers finds that middle school and high school students who smoke only marijuana do better in school than their peers who smoke tobacco. The study, in the Journal of School Health, isn't a small one, either — lead author Michael Chaiton and his team examined 30 years of data involving about 39,000 Ontario 7th, 9th, and 11th graders who participated in surveys from the Centre for Addiction and Mental Health.

What the study doesn't conclude, though, is that marijuana is better for you than tobacco or even makes you a better student. First of all, 92 percent of tobacco users in the study also smoke weed (while only 25 percent of marijuana tokers also smoke tobacco). Marijuana-only users' academic performance is "relatively better" than that of tobacco and tobacco/pot smokers, explains Chaiton, because the students who still smoke cigarettes these days come from "a fairly marginalized population, quite a vulnerable population."

Basically, tobacco has fallen out of vogue in schools, he adds. "Social norms have changed and the population of people who use marijuana are more like the general population." That's mildly good news for pot enthusiasts, since it suggests weed is now considered normal and tobacco deviant. But it doesn't mean students should feel good about waking-and-baking on school days. Or, probably, ever. Tobacco and marijuana are "similar drugs in many different ways," Chaiton says. "People dramatically underestimate the risks associated with cannabis use, particularly among youth." Peter Weber

On the final half day of Barack Obama's presidency, the S&P 500 stock market index closed up slightly at 2,271.31. Counting from this day in 2009, when that same index closed at 805.22, that marks a total gain of over 282 percent. The NASDAQ is up even more: 386 percent. Though that's without accounting for inflation, it's still the largest gain of any president since Dwight Eisenhower in the 1950s, as Reuters demonstrates.

Great news for stockholders, though it's worth noting that median wages have not shown nearly the same upward trajectory. Again leaving aside inflation, they only increased by about 14 percent from 2009-2015 (the most recent data that is available). Ryan Cooper

The Bible passage read on the morning of President Donald Trump's inauguration reportedly referenced his plans to build a border wall. Though the traditional inauguration prayer at St. John's Episcopal Church in Washington, D.C., was closed to the public, a transcript obtained by Time revealed Pastor Robert Jeffress chose to read an Old Testament passage from the Book of Nehemiah that "focuses on the rebuilding of walls around Jerusalem," CBS News reported.

"When I think of you, President-elect Trump, I am reminded of another great leader God chose thousands of years ago in Israel," Jeffress, a Trump supporter, reportedly said. "The nation had been in bondage for decades, the infrastructure of the country was in shambles, and God raised up a powerful leader to restore the nation. And the man God chose was neither a politician nor a priest. Instead, God chose a builder whose name was Nehemiah."

Jeffress, whose stances on Islam and homosexuality have made him controversial, reportedly went on to say that the "first step of rebuilding the nation was the building of a great wall," and that Nehemiah's wall was specifically commissioned by God "to protect its citizens from enemy attack." "You see, God is NOT against building walls!" Jeffress said, according to CBS News.

Per Jeffress, Nehemiah's wall was completed in just 52 days. If Trump sticks to that timeline, we'll have a big wall on the U.S.-Mexico border by mid-March. Becca Stanek

Hillary Clinton attended the inauguration ceremony of President Donald Trump on Friday, making her way to the U.S. Capitol to "honor our democracy and its enduring values." In doing so, she watched as Trump took the presidential oath of office, the culmination of their election rivalry after Trump defeated her in the election last November.

By returning to Washington, D.C., Clinton was also back face-to-face with some of her adversaries in Congress — like Rep. Jason Chaffetz (R-Utah), who has been a ferocious critic of Clinton's as chair of the House Oversight Committee. But when Clinton walked up the stairs past Chaffetz at the Capitol, the congressman shook her hand:

So pleased she is not the President. I thanked her for her service and wished her luck. The investigation continues.

But a warm embrace of bipartisanship, this was not: Check Chaffetz's caption, where he reaffirms he is "so pleased" Clinton is not the president. As MSNBC's Chris Hayes notes, Chaffetz was once none-too-pleased at the prospect of a President Trump, either. But hey, it's Washington — minds change all the time. Kimberly Alters

President Donald Trump received messages of congratulations and concern from across the globe after he was sworn into office Friday, delivering an inaugural address that heavily emphasized an "America first" stance.

Japanese Prime Minister Shinzo Abe, Russian Prime Minister Dmitry Medvedev, Israeli Prime Minister Benjamin Netanyahu, and Mexican President Enrique Peña Nieto each expressed a desire to strengthen their countries' respective ties with the U.S, while Canadian Prime Minister Justin Trudeau said in a statement he looks forward to working with Trump "to restore prosperity to the middle class." Pope Francis encouraged Trump to be guided by America's "rich spiritual and ethical values." Others weighed in on Twitter:

Meanwhile, German Chancellor Angela Merkel, the de facto leader of the European Union, visited an art museum instead of listening to Trump's inaugural address, and German Vice Chancellor Sigmar Gabriel showed concern over Trump's "nationalistic tones." "I think we have to prepare for a rough ride," Gabriel said. Becca Stanek

President Donald Trump's former campaign manager, Corey Lewandowski, got temporarily blocked from the inauguration platform Friday by the Capitol Police, Roll Call reports:

Minutes before President Barack Obama and Trump made their way through the Capitol Crypt, Lewandowski was stopped by Capitol Police as he tried to make his way through.

"Please have somebody bring me that ticket," he said on the phone. "I just can't get past. I'm literally standing at the — I can see, like, the members of what is probably the Cabinet. I can see the people walking onto, like, in the camera shot."

He continued, "I'm standing right outside the Rotunda on the Senate side, I can see the procession."

Lewandowski was surrounded by a stakeout of reporters and staff waiting to watch the outgoing and incoming presidents and their families.

Capitol Police asked Lewandowski if he was a member of "staff," to which he responded, "I'm Mr. Trump's campaign manager." [Roll Call]

Technically, Lewandowski was more or less fired from the campaign in June, when he was replaced by Kellyanne Conway. Trump had sparked heavy criticism for his continued work with Lewandowski after Lewandowski was accused of violently grabbing a reporter.

While Roll Call adds that Lewandowski yanked out four different badges to try to get through, only to fail, it appears he did eventually make it onto the platform. Jeva Lange

President Donald Trump's inaugural address didn't go over well with everyone. Based off of Twitter, several of Trump's conservative critics weren't exactly bowled over by the president's talk of the "American carnage," "America first," and "radical Islamic terrorism." Some described it as "depressing," "dark," and "scary," while others called the address "combative" and "authoritarian":

Friday may be for the 45th man in the White House. But Saturday is for the women.

The Women's March on Washington, which begins at 10 a.m. on Saturday, is gearing up to be a huge protest, with hundreds of thousands of people expected in the capital and sister marches taking place in all 50 states as well as in cities around the world.

Today, those women are on the move.

Surprised, delighted, and inspired Twitter users have been posting photos of D.C.-bound planes almost entirely filled with female passengers. In the photos, many women wear bright pink hats, some are dressed in protest Ts, and most are sporting big, eager smiles. One Southwest flight even turned the cabin lights pink in honor of the march. Here is just a sampling of all the planes packed with women. Lauren Hansen
