Stoners have one big holiday every year: April 20, aka 4/20. But there are plenty of other events, year-round, that are ideal for the adventurous. So here are five of the biggest cannabis competitions, festivals, and parties, from January to December each year.

Make sure you pack what you need, meaning weed and a way to smoke it. You’ll find plenty for sale at many of these events, and lots of samples, but it’s wise to bring your own anyway – unless it’s forbidden.

High Times Cannabis Cup

Cannabis CupThis world-famous contest takes place five or six times a year, in six different cities: Amsterdam, Los Angeles, San Francisco, Denver, Seattle, and Clio, Mich.

Winning the Cannabis Cup at any of these events can catapult a strain and its growers into national stoner fame. The next contest and marijuana expo will take place in Amsterdam in late November, its 27th appearance in that city.

The events in California and Michigan are open to medical marijuana patients only, while the events in Washington, Colorado, and Holland are open to all adults.

4/20 in Denver

This year the party coincided with Denver’s fourth annual Cannabis Cup, so the city was hit with a double whammy. Police started cracking down, especially on partygoers who give pot to minors.

“I got calls to my office last year about people falling onto Colfax [Avenue] while leaving this event,” said Denver City Council Member Charlie Brown. “They were so stoned they couldn’t walk.”

Not that we would ever encourage anyone to block traffic or risk a stampede, but . . . awesome.


Seattle HempfestSeattle’s annual HempFest is one of the largest marijuana festivals in the world. It’s held in August, so you’ll have to wait until next year if you missed it.

This outdoor party started in 1991, when it was known as the Washington Hemp Expo. Just 500 stoners showed up for the first festival, and 20 volunteers staffed the event. This year, more than 200,000 people came.

The festival has grown from a small gathering of neo-hippies into a massive, professional event that draws stoners from all over the country.

Hash Bash

Ann Arbor Hash BashAnn Arbor’s yearly Hash Bash has been celebrating marijuana and our right to use it since 1971, back when pot was really illegal. This city is one of the most liberal in America, so “laid back” is the order of the day.

There’s just one problem: Hash Bash is held at the University of Michigan, and the school prohibits pot on its campus (the rest of Ann Arbor is very decriminalized).

Not that that’s ever stopped anyone.

Marijuana Business Conference & Expo

More than 1,000 professionals and investors come to the Las Vegas conference in November from more than 30 states and 10 countries.

Dozens of speakers and hundreds of exhibits will be available during the three-day event, and networking opportunities abound. There will be nearly 30 new classes, a “marijuana business crash course,” and a networking breakfast focusing on women-owned businesses.
