A zip of weed is slang for an ounce of cannabis, equaling 28 grams. The term originated from using Ziploc bags for discreet transport. Prices range from $100 to $400, depending on quality and location. A zip can last daily users about a month and can be stored for up to a year if kept properly. This measurement is common in both legal and illegal cannabis markets. Click here For more info: https://www.herbwellcannabis.com/blog/how-much-is-a-zip-of-weed-what-you-need-to-know
