From a 1970s Joke to a Madison Icon: The Story of “Thank You For Pot Smoking”

If you’ve spent any time in Madison, Wisconsin, or traveled in counterculture circles, you’ve seen it: the bold, friendly font that politely declares, “Thank You For Pot Smoking.” It’s one of the most recognizable slogans in cannabis history. But did you know it started as a family joke in a Madison living room? Today, that legacy is being carried forward by GreenRX, ensuring that this piece of Wisconsin history continues to thrive in the modern era.

1978: The Spark of an Idea

The story begins in 1978 with Bob Kundert and his sons, Jeff and Eric. While watching television, the family saw a public service announcement featuring the ubiquitous “Thank You For Not Smoking” placard from the American Cancer Society.

In a moment of classic stoner wit, one of the sons jokingly swapped the “n” for a “p.” Bob took it a step further, reimagining the “American Cancer Society” as the American Cannabis Society (ACS).

What started as a laugh became a mission. Bob Kundert, a hard-working construction professional and Vietnam veteran, saw cannabis as a helpful alternative to alcohol and a plant that had been unfairly maligned. He spent the rest of his life fighting for “the truth about cannabis,” often wearing his signature “Thank You For Pot Smoking” shirt until his passing in 2000.

The Modern Era: GreenRX and the ACS

For years, the American Cannabis Society operated as a grassroots advocacy group, led by Bob’s son, Jeff Kundert. However, as the legal landscape changed, the brand needed a way to evolve from a protest movement into a provider.

Enter GreenRX. Today, the “Thank You For Pot Smoking” brand is a division of GreenRX Wisconsin. This partnership has allowed the iconic logo to move from bumper stickers to high-quality products.

• Local Roots: GreenRX is a Madison-born network, with its flagship location on Lien Road serving as the modern home for the American Cannabis Society.
• The Products: You can now find the trademarked logo on everything from premium Delta-8 and Delta-9 gummies to the classic apparel that started it all.
• The Vision: Under the GreenRX umbrella, the mission has expanded. They continue to support the ACS philosophy of “Grow, Use, and Share”—advocating for the right of individuals to cultivate their own plants and share them with friends, keeping the spirit of the original movement alive.

Why It Still Matters

In a world of “Big Cannabis” and corporate dispensaries, the “Thank You For Pot Smoking” brand remains a symbol of the “little guy.” It represents a 50-year journey from a living room joke to a respected Madison institution.

When you see that logo at a GreenRX location in Sun Prairie, Sauk City, or Madison, you aren’t just looking at a brand; you’re looking at a piece of Wisconsin’s counterculture DNA.
