What Is a Zip of Weed? The Simple Definition

A zip is a slang term for one ounce of cannabis. It's one of the most common quantities you'll hear at a dispensary, and knowing what it means helps you shop with confidence.

MeasurementGramsCommon Name
1 zip28 gramsOunce
Half a zip14 gramsHalf ounce
Quarter zip7 gramsQuarter ounce
Eighth3.5 grams1/8 ounce
Vic7 gramsQuarter (slang)

So a zip equals 28 grams. A half zip is 14 grams, a quarter zip is 7 grams, and there are 8 eighths (3.5 grams each) in a full zip. The term "vic" is also slang for 7 grams — same as a quarter zip. If you're wondering, "Is a vic 7 grams?" the answer is yes.

At Garden of Eden, we use standard measurements so you always know exactly what you're getting. Whether you're ordering online or visiting our cannabis dispensary in Tracy, our budtenders can help you pick the right amount.

Zip vs. Ounce: Are They the Same?

Yes, a zip and an ounce are exactly the same amount — 28 grams of cannabis flower. The only difference is the name: 'zip' is slang, while 'ounce' is the standard unit of measurement.

TermWeightUsage
Zip28 gramsSlang, common in casual conversation
Ounce28 gramsFormal, used on menus and labels

So if you hear someone say 'I picked up a zip,' they mean they bought one ounce of cannabis. At our Tracy dispensary, we use both terms so everyone feels comfortable.

Why Is an Ounce Called a Zip? The Origin Story

The term 'zip' comes from the Ziploc bag. In the early days of cannabis culture, a standard ounce of flower fit perfectly into a small Ziploc bag. The bag's zip-top closure gave the measurement its name.

Over time, 'zip' became shorthand for the amount itself — one ounce (28 grams). It's one of the oldest and most common slang terms for an ounce, still used widely today from Tracy to Stockton and beyond.

So when you hear 'zip,' just think of that familiar plastic bag and the 28 grams it holds.

How Much Weed Should You Buy? A Zip or Less?

A good fit if…

  • You're a regular smoker — a zip lasts a heavy user about a week or two, depending on consumption.
  • You want the best value — buying in bulk (a zip) usually costs less per gram than smaller amounts.
  • You share with friends — a zip is enough for a group session or to split with a buddy.

Consider another option if…

  • You're new to cannabis — start with an eighth (3.5 grams) or a quarter (7 grams) to see what works for you.
  • You only use occasionally — a half zip (14 grams) or less may be plenty to avoid waste.
  • You're on a tight budget — smaller amounts like an eighth or quarter cost less upfront.
