Penjamin Meaning: Where the Weed-Pen Slang Came From (and What’s Actually in the Cart)

Penjamin meaning, in one line: a “penjamin” is slang for a cannabis vape pen, usually a battery with a pre-filled THC oil cartridge, sometimes an all-in-one disposable. The word mashes “pen” (what people already called vapes) with “Benjamin” (slang for a $100 bill), and it got its comic polish from internet culture, not from any company. That’s the whole definition. The rest of this piece covers where it actually came from (earlier than most explainers say), the little dialect that grew up around it, why the word now also names a product, and the part every meme skips: what’s in the thing you’re inhaling.

Quick framing before we start. This is an explainer for adults, 21 and over. Cannabis laws vary a lot by state and country, so nothing here assumes vaping THC is legal where you live. Also, we don’t point anyone toward products or sellers.

Penjamin meaning: the short answer (and the slightly longer one)

The short answer is above: a penjamin is a weed pen. The slightly longer answer is that the word is doing two jobs at once, and that’s why it stuck.

First, it’s a pun. “Pen” has been shorthand for vaporizers for over a decade because the early ones were shaped like fat ballpoints. “Benjamin” has meant a $100 bill for even longer, after Benjamin Franklin’s portrait. Put them together and you get a word that sounds like a person’s name, and that’s the second job: it’s a personification. People don’t say “my vape.” They say “Penjamin,” or “Mr. Penjamin,” or the full formal “Penjamin Franklin,” as if the device were a slightly disreputable roommate.

That second job explains the tone. The penjamin meaning isn’t just “vape,” it’s “vape, said with a smirk.” The word is almost always used ironically, in mock-formal sentences (“may I offer you a hit of the Penjamin, good sir”), and usually in a joke about someone getting higher than they meant to.

What it usually refers to, in practice:

• A cart and battery: a small glass or plastic cartridge of cannabis oil screwed onto a slim rechargeable battery. This is the classic penjamin.
• A disposable: an all-in-one pen with the oil and battery sealed together, thrown away when empty.
• Loosely, any weed vape: including dab pens for wax and, increasingly, as a joke word for other things entirely (more on that drift below).

What it usually doesn’t mean: a nicotine vape. Context sometimes blurs this, but if someone says penjamin, assume THC unless they say otherwise.

Where “penjamin” came from: a 2019 tweet, then a 2022 video

Most explainers of the penjamin meaning say the first known use was a September 2019 tweet. That’s close, but not quite first. Here’s the timeline as best the record shows it.

• June 6, 2019: Wiktionary’s citation list includes an archived Twitter post in which someone announces they’ve named their dab pen, and “he is dubbed penjamin.” That’s the personification already fully formed, three months before the tweet everyone else cites.
• September 2, 2019: @youngfishgod posts “Just hit the penjamin franklin n I can’t stop eating out of the fridge.” Know Your Meme lists this as the earliest known use, and most articles copy that line. The Franklin flourish shows the Benjamin pun was part of the joke from the start.
• January 6, 2021: “Penjamin” gets its first Urban Dictionary entry, defined as “another name for a dab pen.”
• October 10, 2022: YouTuber and streamer Fulcrum uses it in a video about going to “double penjamin city” and taking a “smackington off the penjamin.” Know Your Meme and Wiktionary both credit Fulcrum with popularizing the term, and that video passed 800,000 views.
• 2023 onward: it goes fully mainstream on TikTok, where clips about hitting the pen too hard pulled millions of plays.

Two honest caveats. First, “earliest known use” only means earliest that someone has found and archived. Slang like this usually lives in group chats for a while before anyone posts it publicly, so the real origin is almost certainly earlier and unknowable. Second, you’ll see confident claims that one specific person “invented” the word. Nobody has documented that, and the existence of two unrelated 2019 users suggests the pun was obvious enough that several people landed on it independently.

If you’re into this kind of thing, the penjamin is part of a long tradition. Weed slang has always cycled through puns and personifications, and lots of it comes from hip-hop and online culture. Our blunt vs spliff vs joint explainer gets into how much of the vocabulary is regional, and how often the same word means different things in different places.

What a penjamin actually is: carts, batteries, and disposables

The penjamin meaning in slang is fuzzy, but the hardware isn’t. If you want to know what someone is actually holding when they say penjamin, it’s almost always one of three things.

The cart and battery (the classic)

A cartridge (“cart”) is a small tank, usually holding half a gram or a full gram of oil, with a heating element and a mouthpiece built in. It screws onto a battery using what’s called 510 threading, a de facto standard size, which is why one battery fits most carts. Some batteries fire when you inhale. Others have a button, and many let you pick a voltage, where lower is cooler and gentler and higher is hotter and harsher.

The disposable (all-in-one)

Same idea, sealed into one unit. No threading, no charging in some cases, and when the oil runs out the whole thing is trash. They’re convenient, but they’re also where a lot of unregulated product ends up, which matters in the safety section below.

The dab pen (technically different)

A true dab pen has an open chamber you load yourself with wax, shatter, or other concentrate. Urban Dictionary and Wiktionary both define penjamin as a dab pen, but in everyday use most people mean a pre-filled cart. If the concentrate side interests you, our explainer on what dabbing actually is covers the vocabulary.

What’s in the oil

The oil in a cart is a cannabis concentrate. Most often it’s distillate, which is refined THC with flavor terpenes added back. Sometimes it’s live resin or rosin, which keep more of the plant’s original aroma. The terpenes are where “strain” flavors in carts usually come from, and some are cannabis-derived while others are botanical blends. Our terpenes list explains what those names on the label are.

The penjamin dialect: blinkers, smackingtons, and the Franklin family

A big part of the penjamin meaning online is the cluster of jokes around it. If you’ve heard the word, you’ve probably heard some of these.

• Penjamin Franklin / Mr. Penjamin / Sir Penjamin: the mock-formal versions. Same thing, more ceremony.
• Hit the penjamin / take a smackington off the penjamin: take a puff. “Smackington” is pure Fulcrum-era nonsense, and that’s the point.
• Double penjamin city: hitting two pens at once, or just being very high. Used as a joke, and worth taking literally as a warning about potency (see below).
• Blinker: holding the draw until the battery’s light starts flashing. Many batteries have a safety cutoff, often somewhere around ten seconds, and the blink means you’ve hit it. In the memes, “hitting a blinker” is the brag. In real life it’s just a very large dose in one go.
• The Pen-family puns: people have stretched the pattern to other names (pen-based celebrity puns get passed around as lists). They mean the same thing.

The word has also drifted. A Wiktionary contributor noted hearing spinoffs like “bluntjamin” and “bongjamin,” and even “penjamin’d” used as an adjective for being out of it on something else entirely. That’s classic slang behavior: once a word becomes a joke template, it stops caring about the original pun. Treat these as reported usage, not dictionary entries.

One more thing the dialect tells you. Almost every penjamin joke is about overshooting: coughing fits, red eyes, staring at a wall, raiding the fridge. That’s funny in a 10-second clip. It’s also an accurate description of what happens when a high-potency product meets a casual puff, which brings us to the gear itself.

Penjamin the slang vs. “Penjamin” the product

Here’s a wrinkle that confuses a lot of searches for the penjamin meaning. Once the word went viral, companies started using it. Search the bare word today and you’ll find accessory shops and dispensary menus listing pen-shaped batteries sold under the Penjamin name, including at least one that doubles as a working ballpoint.

That’s why some product pages tell the story backwards. One retailer writes that the name “is derived from Benjamin Franklin, whose face was printed on the pen’s original packaging.” The timeline above shows the slang came first, by years. The product borrowed the meme, not the other way around.

So the penjamin meaning now splits in two:

• Lowercase penjamin: the generic slang, meaning any weed pen. This is most of what you’ll hear.
• Capital-P Penjamin: a specific branded device. You’ll mostly run into this on retail sites.

We’re not going to review or recommend any of them. Our lane is explaining the culture, not selling the gear. One observation, though: a lot of the marketing around pen-shaped batteries leans on “nobody will know what it is.” That pitch shouldn’t be the reason anyone picks a device. Whether a product is discreet tells you nothing about whether the oil inside it is clean, which is the question that actually matters.

Our gear guides stick to things we can actually speak to, like grinders and rolling papers.

Why a penjamin hits harder than a joint

This is the part of the penjamin meaning the memes get right. The jokes about overshooting aren’t exaggerating much, and there’s a measurable reason.

A cart’s oil is a concentrate, and concentrates are strong. The largest look at this comes from Washington State’s legal market. Researchers analyzing more than 44 million legal purchases found that extracts for inhalation averaged 68.7% THC, versus 20.6% for flower (Smart et al., Addiction, 2017). Carts belong to that extracts category. That’s more than triple the THC by weight, delivered in a smooth, low-smell puff that doesn’t feel like much going in.

That combination is the trap. Smoke from a joint is harsh enough that most people naturally pace themselves. Vapor is gentle, so it’s easy to take a long draw (hello, blinker) without noticing how much you’ve taken in until a few minutes later. Inhaled THC tends to come on within minutes and build for a while after that, so a second and third puff before the first one lands is how people end up in “double penjamin city” by accident.

If you’re an adult in a place where it’s legal and you’re choosing to use one, the boring advice is the right advice:

• Start with one short puff, not a blinker. Wait at least 10 to 15 minutes before deciding you need more.
• Use a lower voltage if the battery allows it. It’s gentler and usually tastes better.
• Don’t stack it with alcohol or edibles if you’re new to it. Effects compound.
• Don’t drive. Not after one puff, not “after it wears off a bit.” Wait it out.
• Know your tolerance. Someone used to flower can still get floored by a concentrate. Tolerance isn’t universal across forms.

Two related things people ask about. THC from a vape shows up on drug tests the same way THC from flower does, and our detection-window guide explains why frequency matters more than method. And if you’re weighing CBD carts against THC ones, our CBD vs THC effects breakdown lays out the reported differences. It describes reported effects, not medical advice. Talk to a doctor for that.

What’s actually in the cart: the part the memes skip

Every penjamin explainer we read covers the pun and the memes. None of the ones we read mentions the most important fact about weed vapes in recent history. So here it is.

EVALI and vitamin E acetate

In 2019, a wave of severe lung injuries hit the US. The CDC named it EVALI (e-cigarette, or vaping, product use-associated lung injury). As of February 18, 2020, 2,807 people had been hospitalized or died, with 68 deaths confirmed, across all 50 states (CDC). The CDC’s findings were specific:

• THC-containing vaping products, “particularly from informal sources like friends, family, or in-person or online dealers,” were linked to most cases.
• Vitamin E acetate, a thickener added to some THC oil, was found in lung fluid from 48 of 51 EVALI patients tested, and in none of the healthy comparison group.
• The CDC and FDA recommend that people not use THC vaping products, particularly from those informal sources, and that nobody add anything to a product that the manufacturer didn’t intend.

Cases fell sharply after the September 2019 peak. But it isn’t a closed chapter. A 2025 review in Chemical Research in Toxicology notes that a definitive mechanism of injury hasn’t been established and that cases continue to be reported (Love et al., 2025).

The hardware itself

Even tested, licensed products aren’t a clean slate. A 2025 study in Scientific Reports looked at six legal Canadian cannabis vape products. When the carts were run on a vaping machine, the aerosol from every sample contained metal particles, including lead, nickel, chromium, cobalt, and tin. The composition matched the cartridges’ own metal parts, and one unused device already had a cracked connector pin (Gajdosechova et al., 2025). In fairness, the particle counts in the aerosol were below what the method could quantify. This doesn’t prove harm. It does show that “lab tested oil” and “clean vapor” aren’t the same claim.

What that means in practice

• Unlicensed carts are the documented risk. That’s not a moral point, it’s where the CDC found the problem. Counterfeit packaging is common, so a familiar-looking box proves nothing.
• Licensed markets require testing, but what gets tested varies by jurisdiction. A certificate of analysis tells you about the oil, not necessarily the hardware.
• Hemp-derived THC vapes are their own mess. They grew up in a loosely regulated corner of the market, so testing can be thin. Don’t trust any label or website promising a vape is legal everywhere.
• Don’t ignore your lungs. If you vape and develop new breathing problems, stop and see a doctor, and tell them exactly what you’ve been using.

None of this is reefer madness. Plenty of adults use licensed carts without incident. It’s just that the penjamin meaning in meme culture is “funny little pen,” and the real-world meaning includes “heated oil plus metal hardware, of variable origin, straight into your lungs.” Both are true. Only one gets the TikTok views.

Penjamin meaning FAQ

What is the penjamin meaning in plain English?

It’s a jokey name for a cannabis vape pen, usually a THC oil cartridge on a battery or a disposable. The word combines “pen” and “Benjamin” and is almost always used ironically.

Is a penjamin the same as a dab pen?

In slang, mostly yes. The dictionaries define it as a dab pen. Technically, a dab pen is loaded with wax or other concentrate by hand, while most “penjamins” are pre-filled oil carts. In conversation nobody draws the line.

Does penjamin mean a nicotine vape?

Usually not. The penjamin meaning is THC by default. Some people use it loosely for any vape, so context decides.

Who came up with the word?

Nobody knows. Archived Twitter posts from June and September 2019 are the earliest documented uses, and YouTuber Fulcrum popularized it in late 2022. There’s no reliable record of a single inventor.

Is Penjamin a brand?

It started as slang. Some companies have since sold pen-shaped batteries under the name, which is why product pages show up for the word. The generic slang came first.

I heard a teenager say “penjamin.” What should I know?

This is a fair worry. Know Your Meme notes the word spread among teenagers in the early 2020s, and a lot of adults first hear it from a kid or a TikTok. It means a THC vape. The CDC is clear that vaping products, THC or nicotine, should never be used by youths. A calm, specific conversation usually works better than a lecture. Talk to your pediatrician or family doctor about health concerns, and if a child has accidentally swallowed or used cannabis oil, call Poison Control (1-800-222-1222 in the US) or emergency services.

Is a penjamin legal?

It depends entirely on where you are, and on what’s in it. Cannabis and hemp-product laws differ by state and country and keep changing. Check your local laws, and don’t take a product’s own marketing as legal advice.

Final thoughts on the penjamin meaning

The penjamin meaning is simple: a weed pen with a name, “pen” plus “Benjamin,” said with a smirk. It got its start in 2019 posts, got famous through a 2022 YouTube video, and turned into a product name once the meme was big enough to sell. Knowing the word makes you fluent in a corner of internet cannabis culture. Knowing what’s actually in the cart makes you safer than most of the people using it.

So, to recap: enjoy the slang, respect the potency, skip anything of unknown origin, don’t drive, and know your local laws. Great plant. Respect it, and treat the little pen with the same respect you’d give a joint, because it can be a lot stronger.
