What is 4/20 and why is it associated with cannabis?

April 20 became the cannabis culture's high holiday through a series of pop-culture references starting with the Waldos in 1971 San Rafael, California. The number 420 spread through Grateful Dead culture in the 1980s and is now the global cannabis-community celebration date.

Michigan 4/20 Guide — Deals, Drops, and Planning the Day

What 4/20 actually is

The 4/20 reference traces to a group of San Rafael, California high-school students in 1971 (the Waldos) who would meet at 4:20 PM to search for an unattended cannabis garden. The number spread through Grateful Dead culture in the 1970s and 1980s before becoming the global cannabis holiday. In Michigan today, 4/20 is the single biggest retail day of the cannabis calendar — comparable to Black Friday for general retail.

What Michigan dispensaries actually run that day

Expect doorbuster discounts on flower (20-35% off), bundle deals on pre-rolls, and brand-sponsored drops where Michigan cultivators release limited-batch genetics specifically for the day. Lines start before open. Curbside slots fill within minutes of ordering. The best move is to order on Dutchie at 8:30 AM and time your pickup window for the post-rush dip (typically 2-4 PM).

How High Club marks 4/20

Both High Club counters — Detroit at 14325 Wyoming Ave and Port Huron at 1007 Lapeer Ave — run extended 4/20 stacks: deeper first-time discounts (above the standard 25%), exclusive Michigan-grown flower drops we hold back specifically for the holiday, and pre-roll bundles from cultivators we work with year-round. The loyalty program multiplies on 4/20, so the points-per-dollar rate is the best it gets all year.

Where you cannot consume on 4/20

Every public space in Michigan — sidewalks, parks (including Belle Isle and Rouge Park), beaches, casino property (MGM Grand, MotorCity, Greektown), stadium grounds (Ford Field, Comerica Park, Little Caesars Arena), and dispensary parking lots. Open-container rules apply to vehicles. Detroit Police and St. Clair County Sheriff both enforce consistently on 4/20, so a celebratory street-side joint is the fastest way to ruin the day. Consume only in private residences where the property owner permits.

Plan the day

If you live in Detroit metro: order from High Club Detroit between 8:30 and 9 AM, pick up curbside between 2-4 PM, consume in a private residence before heading out for evening entertainment. If you live in Port Huron region: same playbook at 1007 Lapeer Ave. Bring a non-driver for any evening transit — operating a vehicle under the influence is a serious Michigan offense regardless of whether the consumption was legal.
