The cannabis world can seem full of slang and jargon to the uninitiated. “Zip” is one of those terms you may hear in conversations at dispensaries, among friends, in online forums, or in popular cannabis music. But what exactly is a “zip,” and why does it hold such a central place in weed culture?
This guide explores the meaning, origin, usage, measurement, legal aspects, and cultural significance of the term “zip” in the context of cannabis.

The Basic Definition of a Zip
Within cannabis culture, “zip” refers to one ounce (28 grams) of cannabis flower. If someone says, “I bought a zip,” it means they have one ounce of weed.
The term is so widespread that it crosses demographic, age, and regional boundaries in the United States and abroad, especially in places where cannabis has become a mainstream and often legal.
A zip always means one ounce, regardless of whether the marijuana is sold legally from a licensed dispensary or illicitly in an underground market. Sometimes you’ll hear variations such as “half zip” (meaning a half-ounce), which carries the same logic.
Origins of the Slang Term “Zip”
The roots of the term “zip” in reference to cannabis flower come from the phrase “ziplock bag.” Cannabis sellers and buyers in the 1970s and ‘80s began using one-gallon ziplock bags as a convenient, airtight solution for storing or selling an ounce of marijuana.
“Let me get a ziplock,” or “a zip,” came to mean a full ounce because that’s what such a bag typically held for most people involved in transactions at the time.
Over the decades, the term stuck, and even as packaging has evolved well beyond basic plastic bags in many states, the reference to “zip” remains shorthand for one ounce among both legacy and new-school cannabis circles.
How Much Is a Zip?
While “a zip” equals exactly one ounce (28.35 grams), visualizing that amount can help people who have only purchased cannabis in smaller quantities.
One zip is equivalent to:
- Eight eighths (8 x 3.5g)
- Four quarters (4 x 7g)
- Two half-ounces (2 x 14g)
In physical terms, a zip of cannabis flower is typically enough to fill a standard sandwich-sized ziplock bag or tightly pack a medium-sized glass jar. If broken into joints, an ounce could roll anywhere between 28–56 average-sized joints, depending on how fat you roll.
Those who prefer bowls or pipes will find a zip lasting even longer, since a typical bowl uses about a quarter to half a gram.
For the cannabis enthusiast, a zip represents a substantial personal stash—enough for frequent use over weeks (for moderate users) or for sharing at small gatherings.
For medical users, buying by the ounce is often the most economical way to both save money and ensure consistent access to their chosen strain.
Why Buy a Zip Instead of Paying for Smaller Quantities?
Cannabis is usually sold in a variety of weights: gram, eighth, quarter, half-ounce, and, finally, the full ounce or “zip.” There are several reasons people prefer to buy by the zip rather than purchasing smaller amounts:
- Better Price Per Gram: Buying in bulk brings the cost per gram down. In most dispensaries, an ounce costs significantly less (per gram) than buying multiple eighths or grams separately. The savings can be substantial, especially for frequent or medical users.
- Convenience: A zip means fewer trips to the dispensary or meeting with a supplier, giving you a steady supply on-hand.
- Consistency: For patients using cannabis medicinally, having an ounce of one strain provides a uniform experience and dosing for weeks, which aids in symptom management and routine.
- Social Sharing: In social circles, showing up with a zip means you can roll plenty of joints or pack bowls for friends, contributing generously to any session.
How Is a Zip Packaged and Sold in Legal Dispensaries?
In jurisdictions where cannabis is legal, zips are typically sold in multiple forms of packaging designed to preserve freshness and meet childproofing or legal requirements.
These can include opaque plastic or glass jars, sealed mylar bags, or specialty containers that limit odors and exposure to air. Most dispensaries label these packages clearly with strain, potency, and harvest dates.
Zips purchased from licensed outlets are weighed precisely to ensure compliance with laws and avoid shorting the customer. In some states, cannabis is prepackaged offsite in lab-tested, tamper-evident containers before being sold to consumers.
Contrast this with the traditional or illicit market, where zips may still arrive stuffed in ziplock bags or vacuum-sealed pouches, sometimes without consistent labeling or weight verification.
How Many Zips Can You Legally Purchase or Possess?
The legal possession limit for cannabis varies widely depending on region, state, or country. In many US states where recreational cannabis sales are legal, such as California, Oregon, Colorado, and Michigan, the maximum amount an adult can purchase or possess is one ounce (one zip) of dried cannabis flower at a time.
Medical marijuana users sometimes receive higher limits, depending on regulations and prescribed amounts.
Trying to buy or carry more than a zip in one visit or transaction may trigger suspicion or penalties, even where cannabis is legal. States often set these limits to ensure purchases are for personal use, not unlicensed resale. Therefore, “a zip” commonly marks the upper edge of legality for a single recreational transaction.
In Canada, the national limit stands at 30 grams—just a bit over a zip, while in some countries and non-legalized regions, the possession of even a single zip may carry severe legal consequences.
Price Range of a Zip
Prices for a zip vary dramatically depending on the legality, geographical area, strain, and level of quality of the cannabis.
In legal states, a zip of high-quality flower commonly costs anywhere from $100 to $300, though premium or rare strains in boutique dispensaries may fetch even higher prices. Black market rates depend on supply, demand, and local laws; sometimes the illicit zip is cheaper, sometimes not.
Buying a zip of shake (broken plant material and trichomes left at the bottom of a cannabis bag) or lower-grade cannabis lowers the cost, while top-shelf, hand-trimmed flower raises it.
Cultural Importance and Usage of the Term “Zip”
The term “zip” has evolved beyond mere street slang to become a cultural reference in music, television, and cannabis lore. Rappers, hip-hop artists, and street poets often mention “zips” in lyrics, where possession of a zip can symbolize both abundance and commitment to the cannabis experience.
On the internet, discussion forums and social platforms like Reddit, Grasscity, or Instagram use “zip” as a quick, almost universal shorthand, making conversations about bulk purchases easier to follow.
For some, the idea of “picking up a zip” reflects a rite of passage—buying in bulk because you are past the casual stage, or because you have embraced the lifestyle fully. Dispensaries also commonly advertise specials for zips, knowing seasoned customers look for the best deal on larger quantities.
Other Related Slang Terms and Alternative Measurements
While “zip” is perhaps the most common term for an ounce, cannabis culture is rich in alternative slang. You may occasionally hear “O” or “onion” (the latter due to the shape and size of a loosely packed ounce inside a bag).
“QP” (quarter-pound, or four zips) and “HP” (half-pound, or eight zips) become relevant in larger-scale transactions, though these are mostly used by suppliers and commercial cultivators.
Conclusion
Understanding what a “zip” means offers immediate insight into both the culture and the commerce of cannabis. It functions as both a practical measurement and a marker of acceptance and fluency within cannabis circles.
Whether you frequent dispensaries, manage a medical regimen, organize sessions with friends, or simply enjoy learning the language of cannabis, the term “zip” will arise time and again in discussions about quantity, pricing, legality, or just plain celebration of good flower.
As legalization advances and the industry evolves, one thing is certain: “zip” will continue its reign as a core part of the cannabis lexicon for years to come.
