Express Summary: Ounces vs grams of weed
Cannabis quantities can be confusing. How much is a gram of weed? How big is an ounce? And an eighth is an eighth of what, exactly? Let’s zoom out. Cannabis flower is often sold in quantities, ranging from one gram to one ounce. Some common terms you hear are an eighth, which means an eighth of an ounce (or three and a half grams), a quarter ounce (or seven grams), and a half ounce, (14 grams).
The smallest amount of cannabis flour you can typically buy is one gram. A gram is going to roll about two joints or three to four bowls, making it a great option for the occasional consumer or when trying a new strain. Next size up is three and a half grams, or an eighth. That’s enough for about seven joints, seven grams or quarter ounce will get you about 14 joints, which means that 14 grams (or a half ounce) can roll nearly 30 joints. So, a full ounce of cannabis, which is 28 grams, can roll nearly 60 joints or pack upwards of 100 bowls. It’s worth noting that pre-rolled joints are often sold in half gram or full gram quantities. You may choose a half gram to share with a friend or a full gram for a larger group.
