“420” in cannabis culture symbolizes 4:20 PM, April 20th celebration, and a cannabis code.” Its origins date back to the 1970s when high school students, known as the “Waldos,” used it as a reference point to gather and search for a rumored cannabis crop. Today, “420” is a global cultural phenomenon, appearing frequently in pop culture and cannabis-related events.

“420” denotes the time of consumption, and its effects, like relaxation, euphoria, altered perception, vary by strain and individual. Despite “420,” cannabis contains THC (psychoactive) and CBD (non-psychoactive), but growers and manufacturers don’t directly link it to cultivation or composition. It’s common to pair “420” with phrases like “420 friendly” to signal a cannabis-welcoming environment or event.
