What Is 4/20? The Origin Story Behind the Holiday

The origin of 4/20 traces back to a group of five high school students in San Rafael, California, in the early 1970s. They called themselves the Waldos, met near the Louis Pasteur statue on their school campus at 4:20 PM to search for a rumored abandoned cannabis crop in nearby Point Reyes.

“420” moved through their social circle, then spread into broader cannabis culture through connections with the Grateful Dead touring community, and eventually became the shorthand the whole country recognizes today.

By the time April 20 became a calendar event, it had grown into something bigger than a single inside joke. It became a day for cannabis advocates to gather, for communities to connect, and for legal dispensaries to celebrate alongside their customers. Today, in Illinois — where adult-use cannabis has been legal since January 1, 2020 — 4/20 history comes full circle in a licensed store near you.

How to Plan Your 420 in Arlington Heights at Tru Essence Dispensary

Tru Essence Dispensary is located at 792 E Rand Rd, Arlington Heights, IL 60004, along U.S. Route 12, a main commercial corridor that connects Arlington Heights with Mount Prospect and Palatine.

As 4/20 approaches, here’s how to set yourself up for a smooth visit:

• Check the menu online first: Tru Essence updates the menu regularly, and product availability during a major retail holiday like 4/20 can move quickly. Browsing ahead of time means you arrive with a plan, not a question mark.
• Come early: Foot traffic at dispensaries during 4/20 tends to peak in the afternoon. Getting there in the morning means shorter lines and more time with the team on the floor.
• Ask questions: The staff at Tru Essence are there to help you land on the right product for your experience level and preference. First-timers and regulars both get the same clear, low-pressure guidance.

Before heading over, you can also pair the day with a stop at Walker Bros. Original Pancake House, a longtime Arlington Heights breakfast spot, or wind down afterward at Passero, an Italian restaurant in downtown Arlington Heights. Arlington Lakes Golf Club, roughly five miles from the dispensary, is another local option if you’re making a full afternoon of it.
