This year, the Food and Drug Administration is joining stoners the world over in celebrating 4/20.

It might take just one puff of cannabis to quickly if temporarily dull depression, depending on the strain, suggests a new study published this month in the Journal of Affective Disorders. But smoking weed for too long might also make you sadder over time, the researchers found.

4/20 is pretty much the favorite number of the internet (and of Gizmodo’s Slack chat), thanks in part to the growing societal acceptance of weed. Nearly two-thirds of Americans, and maybe even a majority of Republicans, now support its legalization. But a new study published today in JAMA Internal Medicine suggests…

Today’s SpaceX launch was spectacular, making the Falcon Heavy the most powerful rocket in the world and wowing us with the synchronized landings of the side boosters. Yadda yadda, historic space stuff. But the payload was Musk’s own Tesla roadster with a spacesuit-wearing dummy in the driver’s seat.

Republicans in Colorado, where recreational marijuana use has been legal since 2012, weren’t prepared to put up with Attorney General Jeff Sessions today. Even if they were, their constituents wouldn’t stand for it.

2017 is bound to usher in an assortment of changes to our society. Most of them will be bad—we’re sure to suffer—but some will be good. For example, last night a Los Angeles-based hero vandalized, or rather modernized, the city’s iconic Hollywood sign to read “Hollyweed.”

The results are in: Teens are inhaling The Good Plant like never before.

The intoxicating effects of cannabis have skyrocketed in the last 50 years as the plant's rapidly widening acceptance has spurred a race among growers to produce ever more potent strains. But even the stickiest of the ickiest buds top out at 25 percent THC per unit weight and, for a new generation of connoisseurs,…

The new Grand Theft Auto V game features medical marijuana dispensaries, just like the ones that really exist in 18 states and the District of Columbia. Now kids (and 40-year-old dudes) can finally experience the virtual thrill of smoking dope.

Most everybody these days smokes marijuana all the time, but they still like to keep it on the "down low" so the police won't write a ticket or ask to see your medical cannabis ID. Now that we know the NSA and FBI are watching and recording your every communication or web search or Amazon cart, why not order this cool…

Well, not really, that's just an urban legend. But even 30 years after his death, Bob Marley remains a cultural, musical, and spiritual icon worldwide. Marley, simultaneously released today in theaters and online aims to be the man's definitive biography.

Unless you have not inhaled through your nose today, you are surely aware that it is April 20, the high holy day for pot smoking.

Archaeologists recently found a 2,700-year-old pot stash, so we know humans have been smoking weed for thousands of years. But it was only about 20 years ago that neuroscientists began to understand how it affects our brains.

Roll that spliff extra phatly, pack some fresh ice into the binger, and set the Volcano to "Blasteroid." It's time for tonight's Stoner Channel. We've collected our best high-times material for the discerning pothead on this, the stoney high holiday, so sit back, relax, and pass that shit on the left, yo.

4/20 is the high stoner holiday fer sure but where does it come from? Like, what are its origins, where's it comin' from, what's its back story man? Luckily, the day has nothing to do with the Nazi.
