While King of the Hill never leaned on marijuana jokes as heavily as shows like South Park or Family Guy, the series still returned to the subject several times throughout its run.
Most of the show’s marijuana humor comes from the same place as much of its comedy: Hank Hill’s rigid worldview colliding with something he does not understand. From legal hemp petitions to head shops, hippie campers and Hank accidentally getting high, here’s every clear marijuana-related reference in King of the Hill.
Season 2, Episode 3 – “The Arrowhead”
While trying to learn more about an artifact found in his yard, Hank encounters a college student asking people to sign a petition to legalize hemp.
At first, Hank is receptive after hearing that hemp can be used for clothing, rope and paper, dismissing its prohibition as typical government overreach. But when the student explains that hemp is “basically marijuana,” Hank immediately panics and backs away.
The joke works because Hank briefly supports hemp legalization for practical reasons, only to reverse course the second he realizes it has any connection to marijuana.
Season 4, Episode 14 – “High Anxiety”
This is King of the Hill’s most marijuana-focused episode.
While waiting at Debbie Grund’s apartment, Hank tries to light his cigarette using Gale’s hand-rolled cigarette. Hank takes a puff, then realizes he has accidentally smoked marijuana.
His reaction is pure Hank: rather than simply acknowledging that he accidentally took one hit, he spirals into panic, believes he may have “marijuana poisoning,” and tries to hide the incident from Peggy, Bobby and the police.
The problem is that Hank’s attempt to conceal the marijuana use makes him look suspicious in Debbie’s death. Eventually, he admits that he and Gale were smoking marijuana around the time of the incident, helping clear Gale and resolve the murder investigation.
The episode uses marijuana less as a stoner joke and more as a perfect Hank Hill anxiety trigger. The marijuana itself is not the real danger; Hank’s shame, fear of drugs and inability to explain himself are what nearly make everything worse.
Season 6, Episode 19 – “Sug Night”
After Hank has a dream about grilling burgers naked with Nancy, Peggy tries to reconnect with him by taking him to Paradise Cove, a nudist lake.
While Hank and Peggy are there, Hank starts grilling early in the morning. One of the nudist women comments on the timing by saying something along the lines of “burgers at 7 a.m.,” then jokes that someone must have the munchies.
The reference is brief, but clear. It uses “the munchies” as a marijuana-related joke while also tying neatly into Hank’s total inability to relax at a romantic getaway without focusing on grilling.
Season 5, Episode 15 – “Luanne Virgin 2.0”
This is a very minor implied reference rather than a major marijuana joke.
Luanne’s brief boyfriend Zack, who works at Foto-Phast, is portrayed with red eyes and a detached, monotone delivery. The show never says outright that he smokes marijuana, but the character is clearly coded as a stoner-type slacker.
Because there is no direct mention of marijuana, this one is best treated as a small visual/character gag rather than a full marijuana storyline.
Season 7, Episode 6 – “The Son Also Roses”
This is one of the show’s clearest marijuana-adjacent episodes, even though the main plot is technically about Bobby growing roses.
After Bobby becomes interested in rose growing, he visits Stems n’ Seeds, a head shop that sells drug-related paraphernalia. Hank and Bobby fail to realize what the store really is, with Hank mistaking the bongs and other items for innocent gardening supplies.
The episode makes the marijuana connection obvious through the store’s name, its products, the staff and even the use of Peter Tosh’s “Legalize It” in the background. One employee later says, “We need more of this weed and more of this dude,” after seeing Bobby’s rose-growing work.
The humor comes from Hank’s total obliviousness. He thinks he has found a quirky garden store, while everyone else can tell he has wandered into a cannabis-themed head shop.
Season 8, Episode 12 – “Phish and Wildlife”
Hank takes Bobby and the guys on a fishing trip built around self-reliance, only for the campground to be overrun by hippies.
Marijuana is not the central focus of the episode, but the entire setup leans on hippie and jam-band stereotypes, including the episode title’s reference to Phish. The episode also includes a character listed as a “stoned hippie woman,” making the cannabis-coded atmosphere clear even without a major smoking scene.
The marijuana reference becomes more direct when Bobby tries to think like a hippie and says, “I’m a hippie, and I’m naked because I smoked all my clothes.”
The episode uses marijuana culture more indirectly than “High Anxiety” or “The Son Also Roses.” It is mainly a broader satire of hippie gatherings, free-sharing rhetoric and Hank’s discomfort around counterculture.
Season 10, Episode 11 – “Church Hopping”
After Hank and his family begin attending a megachurch, they meet Bryce Carmody, a church employee with a troubled past.
Bryce mentions that he once sold marijuana out of his grandmother’s house, placing marijuana into the episode as part of his backstory. It is not a major plot point, but it is a direct reference.
The joke fits the episode’s larger satire of megachurch culture, where Bryce’s past is treated as something that has been folded into a redemption story and customer-service persona.
Season 12, Episode 6 – “Raise the Steaks”
Hank becomes involved with an organic co-op after discovering how much better its food is than what he gets from Mega Lo Mart.
In one scene, Appleseed buys food for Hank and also brings him hemp toilet paper. Hank immediately wants nothing to do with it and throws it away.
The reference is brief and involves hemp rather than marijuana flower, but it fits the show’s larger pattern: Hank may appreciate practical, high-quality goods, but any whiff of hippie or cannabis culture makes him uncomfortable.
Season 13, Episode 18 – “Uh-Oh, Canada”
During the episode involving Canadian neighbors, Dale’s relationship with smoking gets a marijuana-related joke.
Dale is a constant cigarette smoker, but the show notes that he says if he were Canadian, he would smoke pot instead. The line is short, but it is a direct marijuana reference and plays into Dale’s strange combination of paranoia, tobacco addiction and anti-government thinking.
The joke also works because it contrasts Dale’s rigid loyalty to his Manitoba cigarettes with the idea that Canadian identity would push him toward marijuana instead.
Season 14, Episode 9 – “No Hank Left Behind”
In the revival season, Joseph appears to quickly hide what looks like marijuana or drug paraphernalia when Peggy unexpectedly enters Bobby’s apartment.
The moment is brief and visual rather than a full plot point, but it works as a small modern update to the show’s marijuana humor. Rather than making the reference a major storyline, the joke is tucked into the background as part of the adult lives of Bobby, Joseph and the next generation.
