A gram of weed, also known as a dime bag or a DUB, is the tiniest measure of dried flower. Most joints are usually rolled with one gram of weed.

The Difference in Retail Weights of Weed

While an eighth is the most common retail weight used in dispensaries, you can expect to come across other weights behind the counter. Before you get confused again, let us shed some light.
