420 is more than just a celebration of cannabis—it’s a time to reflect on how we engage with the plant and the planet. As the cannabis industry grows, so does its environmental impact, from excessive packaging to energy-heavy cultivation practices. Thankfully, a new wave of eco-conscious brands is proving that you can get high while keeping your footprint low. Whether you're rolling up at home or planning a greener group sesh, here are 10 cannabis companies—five from Canada and five from the U.S.—that are doing sustainability right.

What Is 4/20?

4/20, pronounced “four-twenty,” is widely recognized as the unofficial holiday of cannabis culture—a global celebration of the plant, the people who love it, and the progress made toward legalization and normalization.

While the origins trace back to a group of high school students in 1970s California who used “420” as a secret code for meeting after school to smoke, the term eventually spread like wildfire through counterculture circles, fueled in part by the Grateful Dead and High Times magazine. Today, April 20th (4/20) is more than just a day to light up—it’s a symbol of community, activism, and cannabis appreciation.

From rallies and music festivals to product drops and mindful sessions at home, 4/20 has evolved into a full-blown cultural moment that highlights both the joy and the justice tied to the plant.

Why Eco-Friendly Practices Matter in the Cannabis Industry

As the cannabis industry continues to grow at lightning speed, so does its environmental footprint. From energy-hungry indoor grow operations to excessive plastic packaging and water-intensive cultivation, the toll on the planet is often overlooked. That’s why embracing eco-friendly practices in cannabis isn’t just a trend—it’s a responsibility. Sustainable growing methods like sun-grown cultivation, regenerative farming, and water recycling help reduce carbon emissions and protect natural ecosystems. Conscious packaging choices—like compostable materials and glass over plastic—cut down on the waste that’s piling up in landfills due to outdated regulations. Supporting eco-minded brands not only helps minimize harm to the environment but also pushes the industry toward a greener, more ethical future—one where enjoying cannabis and caring for the planet go hand in hand.
