Quick Answer: What Is 420?
Origin: The term “420” originated in 1971 with a group of California high school students called “the Waldos” who met at 4:20 p.m.
Today: April 20th (4/20) is an unofficial worldwide cannabis holiday and day of advocacy
In Texas: While recreational cannabis is illegal, the Texas Compassionate Use Program (TCUP) provides legal medical cannabis access for qualifying patients
420 is a term rooted in cannabis culture that originated in 1971 and has grown into a global symbol for cannabis advocacy — including medical use. In Texas, where the Compassionate Use Program (TCUP) provides legal low-THC cannabis for qualifying patients, April 20th is an opportunity to learn, connect, and take action.
Where Did 420 Come From?
The term traces back to 1971 and a group of California high school students called “the Waldos,” who met at 4:20 p.m. to share cannabis. Their code spread through Grateful Dead circles and was popularized nationally by High Times magazine in the early 1990s. Today, April 20th (4/20) is an unofficial worldwide cannabis holiday.
What Does 4/20 Mean for Texas Medical Patients?
In Texas, recreational cannabis remains illegal — but the Texas Compassionate Use Program (TCUP) gives qualifying patients legal access to low-THC cannabis through a licensed physician’s prescription. Following HB 46 (effective September 2025), the qualifying condition list now includes chronic pain, traumatic brain injury (TBI), and inflammatory bowel disease, opening the program to millions more Texans.
This 4/20, if you’ve been curious about medical cannabis, it’s a great time to take the first step.
