In celebration of 4/20, the unofficial yet universally recognized day of united weed smoking, Bob Marley’s son Ziggy Marley wants to send out some warm stoner sentiments, mostly because he feels the holiday is unfairly overlooked in comparison to, say, Valentine’s Day, New Year’s Day, or Christmas Day. In an open letter posted on Billboard, Marley explains the layered meanings of this dankest of days.

What does 4/20 really mean to Ziggy Marley? Besides the typical means of celebration, which may or may not include smoking, eating, listening to music, and going to concerts, Ziggy also wishes for people to understand that 4/20 is all about the rights of plants.

For me, 4/20 means more than just a day to relish in the delights of natures oral herbal bliss. It is a day of an idea, of a philosophy that has been planted but is yet to be reaped. A solution for the fix. A day when the rights of a simple plant life form to exist for the benefit of mankind without persecution and discrimination — honored and celebrated, even.

What? You thought 4/20 was about you and your rights? I guess it is, too, but mostly it’s about the rights of this peaceful plant. At least that’s the 4/20 way of looking at it. Every 4/20, the world should come to know more and appreciate more the potential of this plant. It is a date of reminder: “I am here for your benefit.

Everyone and everything in this world has rights. Why not the plants and trees that allow us to survive on this planet? Human rights, animal rights — and now plant rights. Someone once said, “You can’t have a green revolution without the greenest plant on the earth.”

Preach on, Ziggy.
