You’re sitting on a couch, someone hands you a slim metallic pen, and with one tiny click, you’re inhaling vapor that tastes vaguely like blueberries and diesel. No lighter. No ash. No smell that lingers in your hair for three days. It feels like we’ve lived in this reality forever, but if you look back just fifteen years, the landscape was totally different. People actually want to know when did weed carts come out because the jump from "sketchy homemade oil" to "global multi-billion dollar industry" happened in what felt like a blink.
It wasn't a single "Aha!" moment. It was a messy, slow-motion car crash of Chinese electronics, medical marijuana laws in California, and a few brave (or bored) chemists.
The short answer? The technology started popping up around 2008, but the "weed cart" as we know it—the reliable, pre-filled 510-thread cartridge—didn't really take over the world until about 2014 or 2015. Before that, it was the Wild West. If you were vaping THC in 2010, you were basically a mad scientist.
The Hon Lik Connection: Where the Tech Actually Started
To understand the birth of the cart, you have to look at the nicotine world. In 2003, a Chinese pharmacist named Hon Lik invented the modern e-cigarette. He was a heavy smoker whose father died of lung cancer. He wanted a way to get nicotine without the combustion.
His design used a piezoelectric element to vaporize liquid. It was clunky. It leaked. It was, honestly, kind of terrible. But it laid the foundation.
By 2007 and 2008, these early "cig-alikes" were making their way into the United States. While most people saw a smoking cessation tool, cannabis enthusiasts saw a delivery system. The problem was that THC oil is way thicker than nicotine juice. You couldn't just pour weed oil into an early 2000s e-cig and expect it to work. It would gunk up the coil in seconds.
2010 to 2012: The Era of "The G-Pen" and Blue Silk
This is when things started getting weird. This was the "pre-filled" pre-history.
Companies like Grenco Science started hitting the market around 2012. You might remember the original G-Pen. It was everywhere because Snoop Dogg put his name on it. But here’s the thing: those weren't really "carts" in the modern sense. You had to manually load wax or "honey oil" onto a heating coil. It was messy. It tasted like burnt metal after three hits.

Around this same time, in the legal-ish medical markets of California and Colorado, the first true pre-filled cartridges began to surface. Brands like Pure 710 and O.penVAPE (launched around 2012) were the pioneers.
O.penVAPE was a game changer because they realized people didn't want to mess with sticky jars. They wanted a plug-and-play experience. These early carts used a lot of thinning agents—mostly polyethylene glycol (PEG) or propylene glycol (PG). If you vaped back then, you remember that weirdly sweet, chemical aftertaste. It wasn't great, but it was discreet. For the first time, you could "smoke" in a movie theater or a park without anyone being the wiser.
The 510 Thread Revolution
Why do almost all carts fit on almost all batteries? It’s because of the 510 thread standard.
The name comes from the length of the connector (5mm) and the number of threads (10). It was a generic Chinese manufacturing standard for e-cigarettes that the cannabis industry simply adopted. By 2014, the 510-thread cartridge became the "USB port" of weed.
Once the hardware was standardized, the floodgates opened.
The Distillate Explosion
Before 2015, most oil in carts was dark, opaque, and tasted like grass. Then came short-path distillation. This chemical process allowed extractors to strip away everything—chlorophyll, waxes, plant matter—until they were left with a clear, golden liquid that was 90% THC.
This is when "weed carts" officially became a cultural phenomenon. Distillate was potent. It was pretty. And because it was tasteless, companies started adding "botanical terpenes" to make a cartridge taste like "Granddaddy Purple" or "Sour Diesel" even if the starting material was just low-grade trim.

2019: The Year Everything Broke (The EVALI Crisis)
You can't talk about the history of weed carts without talking about the 2019 lung injury crisis. For a few years, the black market was flooded with fake brands like Dank Vapes, Exotic Carts, and Mario Carts.
These weren't real companies. They were just empty packaging bought in bulk from sites like Alibaba and filled by people in their basements with whatever they could find. To make the oil look thicker (a sign of high quality), some people started adding Vitamin E Acetate.
It was a disaster. According to the CDC, thousands were hospitalized with EVALI (E-cigarette or Vaping Use-Associated Lung Injury).
This moment actually sped up the "legal" evolution of carts. It forced states to implement strict testing for heavy metals, pesticides, and thinning agents. It’s the reason why, if you buy a cart today in a legal dispensary, it comes with a "COA" or Certificate of Analysis. The era of "mystery oil" started to fade, at least for people with access to legal shops.
How Modern Carts Differ From the Originals
If you compared a 2013 cart to a 2024 cart, the 2024 version wins every single time.
- Wicks vs. Ceramics: Early carts used cotton or silica wicks. They burnt easily. Modern carts use porous ceramic heating elements (like CCELL technology, which took over the market around 2016).
- Live Resin and Rosin: Distillate is "old school" now. Today, the high-end market is all about Live Resin or Live Rosin. These carts are flash-frozen at harvest to preserve the full spectrum of the plant. They don't just get you high; they actually feel like smoking a flower.
- Hardware: We have "disposables" now that are smaller than a lighter and rechargeable via USB-C. In 2010, you had to carry a battery the size of a TV remote.
Why the Date Matters
So, when did weed carts come out?
If you mean "when could I first buy one," the answer is roughly 2011–2012 in California medical dispensaries.
If you mean "when did they become a household name," the answer is 2015–2016.

Actionable Tips for the Modern Consumer
Since you’re looking into the history, you’re likely either a collector of cannabis lore or someone looking for a better experience. Here is how to navigate the "post-history" world of carts:
1. Check the Hardware
Avoid plastic cartridges. Look for glass tanks and ceramic mouthpieces. If the brand uses CCELL or AVD hardware, it’s usually a sign they aren't cutting corners. Cheap metal can leach lead into the oil when heated repeatedly.
2. Learn the Extraction Method
- Distillate: High THC, cheap, often has artificial flavors. Good for a quick buzz, but the high can feel "flat."
- Live Resin: Tastes like the actual plant. Uses chemical solvents (like butane) but preserves terpenes better.
- Live Rosin: The gold standard. No chemicals, just heat and pressure. It’s the most "natural" vape experience you can get.
3. The Bubble Test is Dead
In 2016, people said "if the bubble moves slow, the oil is good." That’s no longer true. Scammers use thickeners to make bad oil look thick. Don't trust your eyes; trust a QR code that leads to a third-party lab test.
4. Storage is Key
Carts are fickle. Keep them upright. If you leave a cart on its side in a hot car, the oil will seep into the airway, and you’ll be sucking on a clogged straw for the next three days. If it does clog, don't keep firing the battery. Use a hairdryer on a low setting to gently warm the glass until the oil thins out.
The technology is still evolving. We’re already seeing "smart" batteries that track dosage and temperature-controlled rigs that prevent any burnt taste whatsoever. The "weed cart" started as a hacked nicotine device, but it has become the most popular way to consume cannabis on the planet.
