You would never walk into your local Toronto cannabis dispensary and blatantly ask for $20 worth of weed. And you’d definitely want to avoid buying weed online in Canada without knowing exactly how much product you’re getting. But if you’re not up to date on how weed is measured and sold, what are you supposed to do when you want to buy some?

Growing and manufacturing marijuana has changed a lot over the last century. Modern technology, increased knowledge, and now the fact that it’s legal for dispensaries to sell marijuana in Canada has changed the entire marijuana industry. But one thing that hasn’t changed much over the years is weed measurements.

Despite the ever-changing slang that’s thrown around on the streets, the actual amounts and measurements of marijuana sold in the black market, physical shops, and even mail order marijuana (MOM) dispensaries has pretty much stayed the same.

So, if your new to the cannabis scene and want to make sure you get enough of your favorite marijuana the first go-around, brush up on your weed measurements right here, right now. Then you can hop on over to one of the best online weed dispensaries in Canada immediately after and get exactly what you want, without buying too little or too much (or spending too much money!).

How Weed is Measured

Before jumping into all the weed measurements you need to know, let’s clear up how weed is measured and sold. To start, low amounts of marijuana start out using the metric system (perfect for Canadians and most everyone else…confusing for Americans!).

As the amount of weed increases, the measurements shift to the US or imperial system (most say boo to that!).  That said, once you get it all down, it’s not so confusing. Until you start throwing in the slang that is. But don’t worry, we’ll give you the lowdown on that too. 🙂

Learning Weed Measurements

Here’s a list of the most common weed measurements you’re likely to be dealing with when buying weed online or in a physical dispensary.

The Gram

This is the lowest amount of marijuana you can buy, though most dispensaries won’t even go this low. It’s also known as a “dime bag” or a “dub.” It gets its nickname from the fact that it almost always costs about $10. But the better the strain, the more you’ll pay, even for this tiny amount.

A gram is enough to roll a couple small joints or pack a few good sized bowls. You’ll get more weed if you buy an indica strain (because they are typically more compact) than if you buy a sativa strain (which tends to be airy and fluffy).

The Eighth (of an Ounce)

This weed measurement is about 3.5 grams and can cost anywhere from $20 to $50 for top-shelf cannabis. Many people enjoy buying an eighth, or a “slice,” so they don’t have to keep visiting the dispensary every time they run out of their small gram. Depending on how much marijuana you smoke, an eighth can last a few weeks. An eighth also happens to be the most common weed measurement.

The Quarter (of an Ounce)

Also known as a “Q” or a “quad,” a quarter is a quarter of an ounce of cannabis, or 7 grams. It’s easy to think of this weed measurement as the equivalent of 2 eighths. To give you a visual idea how much cannabis we’re talking about, a quarter will overflow a standard prescription bottle or a small glass jar. In terms of a Ziploc bag, think about two fingers high worth of weed.

The cost for this amount of marijuana will range roughly between $50-$100 depending on the source, strain, and quality.

The “Ounce”

Twenty-eight grams make up an ounce of marijuana (so a half ounce is 14 grams). This is plenty of cannabis to last a long time and costs a hefty $80-$160 or more. The ounce is also known as “O,” “Full O,” “Z,” or “zip,” because an ounce of weed can usually fill a Ziploc bag.

In Canada, you can only have 30 grams, or about an ounce, of weed on you at any time. But don’t worry, this should be enough. Any more than that and you’re going to need some serious help with storing your marijuana so it doesn’t go bad.

How to Measure Your Weed

Making sure you get what you pay for is important, especially when dealing with a new dispensary. Here are the best ways to measure your weed so you know you’re not getting scammed.

1. Using a Scale

A scale is the best way to measure the weight of your weed and make sure you get what you pay for. They are super accurate and ensure your supplier didn’t “round off” to their benefit.

Never use a kitchen scale to measure your weed weights because they are just not that precise. It’s best to get a scale that’s accurate within 0.1 grams. In addition, try to buy a scale that has a 200 gram capacity so you can get the most use out of it, no matter how much or how little marijuana you have to weigh.

2. The Eyeball Method

If you’ve smoked enough weed, and usually buy the same amount every time, it’s likely you’ve gotten good at eyeballing just how much cannabis your money gets you. Though it’s not a very effective way to measure your weed, it’s good for giving you a rough idea. After all, you’ll be able to tell the difference between an eighth and an ounce easy just by looking at it.

3. The Penny Method

If you’re feeling creative, you can always create a makeshift scale using a ruler and a penny. Balance the ruler on your finger and place a penny (dated after 1982) on one end and your weed on the other. The penny weighs 2.5 grams, which gives you a good starting point if you have more than that.

4. Smartphone App

Many smartphones have apps now that weight things – even your marijuana! Again, though not the most accurate, they are good for giving you a general idea whether you’re being totally ripped off or not.

And there you have it! You now know your weed measurements the quick and easy way.
