How is Cannabis Sold By Weight | Cannabis Weights

The most common cannabis measurements 

Across the world, cannabis flower is usually measured in increments within an ounce - a gram, an eighth, a quarter, a half, and an ounce. Although cannabis can also be sold in another amount, like pounds, this is typically reserved for industrial spaces, as purchasing and possessing cannabis of this weight is illegal in most recreational, health, and medicinal markets in the United States. Yes, cannabis flower may be legal in one way or another in most states, but there are still regulations on the quantity and weights one can purchase on sale.

At CarePac, all our CBD and THC packaging is made-to-order for dispensaries, meaning it can be purchased in any size, color, or material. For the purpose of this article, we’ll discuss the most common cannabis measurements so you can purchase the cannabis packaging in the size that’s right for your weed quantities. 

Weed measurements 1: Gram 

Outside of one-hitters, a gram is the smallest weight of flower a customer can purchase at recreational or medical dispensaries. This size is often reserved for new customers to try something new, without having to waste money in case they don’t like the strains, taste, or product. This amount will fit into the palm of your hand and is enough marijuana to fill one average-sized joint or two smaller ones. 

It’s important to note that all cannabis sizes, grams included, are measured by weight -- so a very dense nug of cannabis flower will weigh as much as a few fluffy pieces of cannabis. Additionally, pre-rolled joints are often sold in one-gram sizes. Inform your customers that all your marijuana is weighed for accuracy, as this is a common misconception in the industry.

Weed measurements 2: Eighth 

An eighth of marijuana equals 3.5 grams, and this is the perfect amount for the average cannabis user. It may seem small compared to a quarter, half an ounce, or a full ounce, but it is the most popular amount purchased in the United States. So, if you’re shopping for CBD and THC packaging, you’ll definitely want to stock up on eighth-sized packaging. 

The reason it’s popular at dispensaries often comes down to freshness. Many customers don’t consume cannabis daily, so this amount is enough to last them up to a few weeks. To enhance the freshness of your cannabis and preserve those precious terpenes and cannabinoids, make sure to purchase cannabis packaging that has a built-in zipper. 

Weed measurements 3: Quarter 

As you probably guessed, a quarter ounce of weed is double that of an eighth -- so 7 grams if you want to get technical. A quarter ounce can fill about 7 joints or 10 bowls, depending on the size of your customer's pipe or bong. This is also a great amount for customers who are interested in making home made cannabutter for edibles, as cannabutter does require more cannabis than you’d think!

Weed measurements 4: Half 

A half-ounce is 14 grams of cannabis. This is a pretty substantial amount of cannabis and is often purchased by customers who consume cannabis daily. If you’re purchasing cannabis packaging in half-ounce sizes, a built-in zipper is essential for freshness.

Weed measurements 5: Ounce & Pound

One ounce of flower is 28 grams, and this is usually the highest volume a customer can purchase at one time. An ounce is commonly called a “zip” because this amount of flower usually fills a small Ziploc bag. Often times dispensaries don’t have an ounce bag -- they’ll divide the cannabis into multiple smaller bags. Fortunately, CarePac does sell ounce-sized bags, so you can impress your customers with one bag for their ounce purchase. 

We do also sell 1-pound-sized stand-up pouches. As mentioned previously, this is best reserved for wholesale cannabis companies that sell their products to buyers or dispensary owners.
