The cannabis industry is a completely new market in our society, however, the purchasing of marijuana has been going on for decades. Due to the large demand of cannabis before legalization, consumers have become familiar with the way cannabis was sold and purchased on the black market. So much so that once cannabis was legalized, the new industry simply adopted the black market way of doing things.
One of the most commonly-sold quantities of cannabis in the United States is the eighth. If you are not familiar with the imperial system of measurements, you may be wondering:
“How much weed is in an eighth?”
Measurements of Cannabis
The gram is your base unit of measurement when it comes to buying cannabis. A single gram is enough for 2-3 joints (depending on how you roll) or about one blunt.
How much weight is a gram of weed?
A gram is the smallest weight of cannabis flower you can buy and it does not weigh much of anything. To put this into context, a gram is one twenty-eighth of an ounce (1/28). One gram is comparable to the size of a bottle cap.
How many grams are in an eighth of weed?
An eighth refers to ⅛ of an ounce of cannabis. An eighth of an ounce technically weighs 3.5436904 grams, but dispensaries and other purveyors typically round down to 3.5 grams. This allows for easier measuring and calculation.
Before you get too bent out of shape by this approximation of convenience, consider that if you use an eighth per week, it would account for only 2.27 grams rounded off per year.
Cannabis retailers tend to use the 3.5-gram figure as the basis for selling larger quantities as well. For example:
- Quarter is typically sold as 7 grams.
- Half ounce is sold as 14 grams.
- Ounce typically weighs 28 grams.
How much does an eighth cost?
Among legal dispensaries, an eighth costs between $30 and $40 on average. In some regions you may find an eighth for as little as $25 or as high as $65. The price of an eighth depends on a number of factors:
- Cannabis Quality: Naturally, more potent strains often fetch a higher price on the market. It is not uncommon for a high-THC strain to cost more than an average or low-THC product. Prices may be higher if the strain has been recently developed or was grown using organic practices as well.
- Taxes and Overhead: Dispensaries are businesses like any other. While cannabis has not been federally legalized, cannabis businesses are still subject to taxation and operational costs including facilities, utilities, payroll, administrative costs, and more. Taxes and the cost of living in your area can cause the cost of an eighth to be higher or lower than the average.
- Supply and Demand: Like other businesses, the cannabis industry is also subject to basic economic principles. If local growers suffer a bad crop or other unforeseen circumstance, the lack of supply can drive prices higher. If advances in growing technology improve, resulting in greater output with similar input costs, the increased supply can cause prices to decrease. Similarly, black market dealers may charge higher prices in an area without an abundance of other supply options, while illegal dealers in states that allow recreational cannabis may entice customers by setting their prices slightly lower than the average retail rate in the area.
What are 5 gram eighths?
As mentioned, an eighth of an ounce weighs approximately 3.5 grams, but you may have heard the term “5 gram eighth” before. 5 gram eighths refer to 5 grams of cannabis sold at the typical price of an eighth. This is usually used as a promotional deal and essentially means you get the same price for more weed.
Common retail weights
Cannabis is usually purchased by the gram, eighth, quarter, half ounce, or ounce. Similar to the black market, if a consumer purchases a larger weight then there is typically a price discount.
- A quarter of weed clocks in at 7 grams. A quarter-ounce of marijuana is enough for five to seven blunts and over a dozen joints.
- A half-ounce is 14 grams. This quantity is also referred to as a half or half “O.” With a half-ounce, you can roll between 7 and 14 blunts.
- An ounce weighs in at 28 grams, equating to four quarters or eight eighths. Ounces are also referred to by other names like a zip or an “O.” The possession limits for most states and countries are cited in grams and ounces. Some states and countries place restrictions on how much weed you can possess at a given time and how much you can purchase per month.
- A quarter-pound is 113.4 grams, which also equals 4 ounces. Quarter-pounds are often called QP for short.
- A half-pound. Weighing at 226.8 grams, a half-pound, or 8 ounces of cannabis is also known as half-pack and half-pounder.
- One pound is equivalent to 453 grams or 16 ounces, enough to put a dent in the bank account. A pound can cost up to $3,000 and can be called a pack or an elbow.
How do people around the world weigh weed?
Every country except Burma, Liberia, and the United States uses the metric system. With different units of measurements around the globe, how do other countries weigh their weed if they are on a different system?
Most of the world has adopted the metric system. The decimal system of measurement is known as the International System of Units (SI). In short, cannabis is measured by grams no matter where you go.
Beyond grams, cannabis weights outside the U.S. are typically referred to in kilograms, or 1,000 grams. One kilo, as it is often called, is 2.20462 pounds.
How long does an eighth last?
Now that you know how many grams are in an eighth of weed, you might be wondering just how long an eighth will last once you purchase it. This depends on several factors including what you typically use to consume cannabis (bowls, bongs, joints, blunts, etc.), how often you partake, and whether you will be sharing with friends.
Typical glass bowls can hold anywhere between 0.25 gram and 1 gram. If you assume the bowl you are using holds roughly half a gram of weed, then you will be able to smoke about 7 bowls when you purchase an eighth. If you smoke one bowl or less per day, an eighth can provide about a one week supply of cannabis.
Joints typically contain between 0.5 and 1 gram of cannabis, so you can expect to make three to five joints per eighth. Blunts often contain over one gram of weed, so you may only be able to roll two or three blunts using an eighth of weed.
Using these numbers, we can extrapolate how much other quantities of cannabis are likely to yield as well.
- 1 gram: approximately 2-3 bowls, 1-2 joints, or 1 smaller blunt.
- Quarter (7 grams): approximately 14 bowls, 6-10 joints, or 4-6 blunts
- Half (14 grams): approximately 28 bowls, 12-20 joints, 8-12 blunts
- Ounce (28 grams): approximately 56 bowls, 24-40 joints, 16-24 blunts
