What does “G” mean?One gram of cannabis. Cannabis is measured in metric grams, and the symbol of this measurement (g) soon integrated into stoner slang. Usually, one gram is the smallest amount of flower available for purchase in a dispensary or adult-use storefront. While it may not seem like much, a gram is good for at least two or three decently sized joints--or, you can go all the way and put it all into one fatty.
“Let me get a G of Green Crack. If I like it, I'll come back for an eighth.”
