Feliz 420!

Every week, we carefully curate the top stories from across the fields of medical research, testing, processing, and plant science. We also bring you the latest in the world of cannabis business and legislation. This week, we took a closer look at the date now synonymous with a celebration of the green stuff – 4/20.

Yes, the day is finally upon us. And, after two years of lockdowns and with more states allowing legal cannabis use than ever before, the festivities are set to be bigger than ever this year. 

I’m sure you’ve all heard the many urban myths surrounding the history of 4/20. Once you wade through the various origin stories related to Adolf Hitler’s birthday, police codes, and a Bob Dylan song, you will most likely arrive at the more widely accepted explanation: that five Californian high school students coined the term as part of their cannabis secret code. Whatever its origins, April 20 is now synonymous with a general celebration of the green stuff. Once seen as a countercultural movement, more and more companies are capitalizing on the event every year – an inevitability given the rapidly changing public opinion around the drug. 

If you do plan to take part in the festivities this year, check out this complete guide to some 150+ events on offer. My top Pick? 420PPM. We are a cannabis science magazine after all, and this has a distinct climate-science flavor. It also links nicely to our newly published piece on indoor VOCs

The Oktoberfest of cannabis?

Paired with the easing of COVID-19 restrictions in the US, 4/20 this year is set to generate a huge profit for cannabis companies. With businesses calling 4/20 the “Oktoberfest of cannabis” and comparing the unofficial holiday to Black Friday, the cannabis industry has been preparing for months. Companies have reported a sales increase of up to 50 percent in previous years and are expecting similar numbers this year – if not a further boost in sales due to COVID-19 restrictions being lifted. Many US businesses have emphasized the celebratory atmosphere they wish to create, and highlighted user experience and accessibility – especially for first-time cannabis users as this could be an opportunity to bring in new customers. On a similar note, 4/20 and less COVID-19 rules also mean that cannabis companies, activists, and artists are coming together at protests such as the Vancouver 4/20 event and educational events such as the High Tide Summit in Portsmouth, US, to discuss cannabis policy challenges and opportunities.

Celebrate good times

If you’re still on the hunt for unique ways to take part in the 4/20 celebrations, how about purchasing your very own NFT mural? 

Leafly has just announced their new pro-cannabis project in collaboration with local artists who have been commissioned to paint murals in Chicago, Portland, Toronto, and Washington, D.C. The murals will be available to purchase for $420 (teehee) and the profits will go directly to non-profit organizations fighting for justice and fairness in the cannabis industry.

About the Authors
Lauren Robertson

By the time I finished my degree in Microbiology I had come to one conclusion – I did not want to work in a lab. Instead, I decided to move to the south of Spain to teach English. After two brilliant years, I realized that I missed science, and what I really enjoyed was communicating scientific ideas – whether that be to four-year-olds or mature professionals. On returning to England I landed a role in science writing and found it combined my passions perfectly. Now at Texere, I get to hone these skills every day by writing about the latest research in an exciting, creative way.
