Zip is a slang term commonly used in the cannabis community to refer to an ounce of marijuana. The term “zip” is derived from the fact that an ounce of cannabis can typically fit into a standard zip-lock bag. One zip equals approximately 28 grams of cannabis.

Zips are a popular measurement for purchasing cannabis due to their practicality for both personal and shared use. Buying cannabis by the zip is often more cost-effective than purchasing smaller amounts, making it a common choice for regular users and those who require larger quantities for medical purposes.
