As of midnight Wednesday, it is legal to possess and use recreational marijuana in Canada.

Provinces and territories will set the parameters of where pot can be purchased and consumed in their boundaries, and the government has sent out mailers to households across Canada notifying them of the new cannabis laws. While adults will be able to purchase dried weed and cannabis oil from licensed producers and retailers, it will be illegal to possess more than 30 grams in public, grow more than four plants in a household, and buy from an unlicensed dealer.

The first legal purchase was made in St. John's, Newfoundland, and while the nationwide market is open, it's not going to easy to buy in some places; in Ontario, for example, retail stores won't open until the spring, BBC News reports, although residents can order online. In British Columbia, there will just be one legal store open on Wednesday. Edibles will be available for purchase within the next year.

Marijuana possession became a crime in 1923, and Prime Minister Justin Trudeau has argued that laws criminalizing marijuana haven't done anything to curb use. Marijuana has been legal for medical use in the country since 2001. With this new law, Canada becomes the second country after Uruguay to make it legal to possess and use recreational marijuana. The government predicts it will earn $400 million in tax revenues from the sale of marijuana every year. Catherine Garcia

President Trump scored a legal victory over porn actress Stormy Daniels on Monday when a federal judge threw out her defamation case against the president, Stephen Colbert said on Tuesday's Late Show.

"The judge's reasoning for why he threw the case out is — it's a little upsetting," Colbert said. "Trump called Stormy a liar on Twitter, but Judge S. James Otero ruled that Trump's speech was protected by the First Amendment because, he said, it was the kind of 'rhetorical hyperbole' normally associated with politics and public discourse in the United States." Colbert dissented: "It's only normal because Trump made it normal! Like how now it's normal to be buddies with Kim Jong Un yet fear the cruel and devious Canadians."

"Trump took immediate advantage of the 'new normal'" and called Daniels "Horseface" on Twitter," Colbert noted. "Yes, 'Horseface.' You heard it straight from the horse's ass. ... But on Twitter, just like in real life, Stormy quickly spanked the president." He read that tweet, which mentioned "bestiality," Trump's "umm ... shortcomings," and ended: "Game on, Tiny." Anyway, Colbert said, "the president of the United States and a porn star are exchanging ad hominem attacks on Twitter — or as Judge Otero would call it, normal."

But Trump "has bigger problems than Stormy, because it's looking more and more like his buddies in Saudi Arabia murdered Washington Post journalist Jamal Khashoggi in their Istanbul consulate," Colbert said. He ran through Saudi Arabia's recent suspicious behavior and the "certain" evidence Turkey claims to have. "So at this point, you'd have to be either stupid or delusional to believe the Saudis' denials. Luckily, our president is both," he said. Trump denies backing the Saudis due to "financial interests in Saudi Arabia," Colbert added. "Here with a counterpoint is Donald Trump."

It all started with a blood drive at his church.

Richard Packman, 74, first donated blood in the early 1990s, and after being told by a phlebotomist he had "big veins," the Chicago resident made the switch to platelets. "It takes longer than a blood donation, but it's well worth it," he told The Chicago Tribune. "I really enjoy being a platelets donor because you really know you're saving lives." It takes about two hours to donate platelets, which are commonly used for cancer patients who lose platelets during chemotherapy treatment, but Packman said the time passes quickly, as he watches a movie or chats with staff.

Packman has spent an estimated 1,000 hours giving blood or platelets, and on Friday, made his 500th donation. A small celebration was held, with streamers and carrot cake, and Packman plans on continuing to donate beyond this milestone. "Just remember one thing: It's better to give than to receive," he said.

Saudi Arabia has for years been known as "the super conservative country where women can't drive, gay people get flogged, and thieves have their hands chopped off," Trevor Noah said on Tuesday's Daily Show. It was taking strides to shed that reputation under Crown Prince Mohammed bin Salman, or MBS, until journalist Jamal Khashoggi vanished while visiting the Saudi consulate in Istanbul.

"So, a Washington Post journalist known for criticizing the Saudi government was seen entering the Saudi consulate, and then he was never, ever seen again," Noah recapped. "Now, I'm not a detective, but come on." The Saudi government has officially claimed Khashoggi left through the back door, but their security camera doesn't record images — an idea Noah found laughable. The Turkish government has another explanation. "Holy shit, 15 assassins, private planes, and a black van?" he asked. "This doesn't sound like real life, it sounds like the opening of a James Bond movie."

"So it's looking more and more like Saudi Arabia had Khashoggi killed, and this isn't just a big deal for Turkey and Saudi Arabia," Noah said. Khashoggi was a U.S. resident who wrote for The Washington Post, and the Saudis are U.S. allies, so this is an American problem, too. But President Trump, pressured to step in, has repeatedly accepted the Saudi leaders' denials, and he even introduced a random new suspect, "rogue killers," he noted. Since nobody's buying that, "Saudi Arabia is preparing to release their latest excuse," Khashoggi dying during an interrogation gone wrong.

"I don't know whether to be horrified or impressed," Noah said. "Because this is diabolical. The Saudi government is testing their excuse before officially using it." Michael Kosta explained why American should be "honored" that Saudi Arabia is testing its excuses because it shows "Saudi Arabia respects us enough to find a lie that works for both of us."

The lieutenant governor of Alaska, Byron Mallott, resigned suddenly on Tuesday, and Gov. Bill Walker (I) said he stepped down due to "inappropriate comments" made two days ago.

"As leaders, we must hold ourselves to the highest standards of conduct," Walker said. The governor said he found out about the comments on Monday, and that they were directed at a woman who has asked that her identity remain anonymous. Mallott and Walker were close, running on a "unity ticket" in 2014; Walker, once a Republican, was elected as an independent, and Mallott is a Democrat.

Alaska Health and Social Services Commissioner Valerie Davidson has been sworn in as lieutenant governor, and she said she was "deeply saddened" by Mallott's resignation and "profoundly disappointed by his conduct," adding, "respect for women and the dignity of all Alaskans is our responsibility." Davidson will replace Mallott as Walker's running mate in an increasingly difficult re-election. Catherine Garcia

President Trump tweeted Tuesday night that the United States has sent a message to several Central American countries regarding immigration.

"We have today informed Honduras, Guatemala, and El Salvador that if they allow their citizens, or others, to journey through their borders and up to the United States, with the intention of entering our country illegally, all payments made to them will STOP (END)!" He didn't STOP (END) there, adding in a follow-up tweet, "Anybody entering the United States illegally will be arrested and detained, prior to being sent back to their country!"

There is a caravan of about 2,000 migrants headed to the United States from Honduras, and earlier in the day, Trump tweeted that if those people do not turn around and go back, "no more money or aid will be given to Honduras, effective immediately!" During the 2016 fiscal year, the U.S. gave Honduras $127.4 million in aid, the United States Agency for International Development says. Many people who migrate from Honduras are fleeing drug and gang violence and poverty, which would all likely grow exponentially if aid is cut off. Catherine Garcia
