mg/g (milligrams per gram) – Potency.

Mg/g. Milligrams per gram. That's literally it.

 

But okay, let me paint you a picture. You buy a gram of flower marked 180 mg/g THC. Inside that one gram? 180 milligrams of pure THC. Not the weight of the whole bud - just the THC itself.

 

This isn't some made-up industry thing either. Labs actually extract and measure this stuff. They can tell you down to the milligram how much THC, CBD, whatever cannabinoid you want to know about, lives in your cannabis. And then they slap that number right on the package.

 

Why should you care? Because guessing sucks. Nobody wants to accidentally get way too high (or not high enough). With mg/g, you know exactly what you're signing up for. Every. Single. Time.

 

Here's how it goes down. Cannabis goes to a lab. Not some guy's basement - an actual certified testing facility with machines that cost more than your house.

 

They take samples (multiple ones, because accuracy matters), grind them up, and run them through equipment that can detect cannabinoids down to tiny, tiny amounts. Gas chromatography, liquid chromatography - fancy stuff that separates out every compound and measures it.

 

The machine spits out numbers. "This sample contains 195 milligrams of THC per gram of material." Lab tech writes it down. Producer puts it on the label. You see "195 mg/g THC" at the store.

 

That's it. No estimates. No "feels like" or "probably around." Just cold, hard data from expensive machines that don't lie. And every legal cannabis product goes through this. Flower, edibles, oils, vapes - everything gets tested and labeled with its mg/g content.

 

Producers actually test multiple times too. Once after harvest, again after processing, sometimes even after packaging. Because nobody wants angry customers showing up with lab results that don't match the label.

 

Because winging it with cannabis dosing is a terrible idea. Trust me on this one.

 

You're new to cannabis? Grab something around 50-100 mg/g THC. You'll feel it, but you won't be calling your mom at 2 AM convinced you've forgotten how to breathe. Been smoking since high school? Maybe you want 200 mg/g or higher. Your tolerance, your choice.

 

But here's where it gets really important - medical users. If your doctor says "take 5mg of CBD twice daily for anxiety," you need to know your CBD oil has 20 mg/g so you can measure out exactly 0.25 grams. No guessing. No "about this much." Exact dosing for exact results.

 

Price shopping becomes way smarter too. That $40 eighth with 240 mg/g THC might actually be a better deal than the $30 eighth at 120 mg/g. You're getting literally twice the THC for just ten bucks more. Do the math.

 

And consistency! You find a product that works perfectly at 180 mg/g? Buy it again and you'll get the same experience. No more "this batch seems stronger" surprises.

 

Same thing, different outfit. Seriously.

 

Ten mg/g equals one percent. Always. So when you see 200 mg/g THC, that's 20% THC. See 15% on a package? That's 150 mg/g. Just move the decimal point.

 

Old-school smokers love percentages. They've been using them forever, makes sense to their brain. "This is 25% THC" clicks immediately. Newer consumers and medical patients? They often prefer mg/g because they're dosing in milligrams anyway.

 

Here's a fun fact: Canada uses mg/g on all labels. The U.S.? Mostly percentages, though some states show both. Europe's all over the map. But they all mean the exact same thing.

 

For flower, I get why people like percentages. Sounds cleaner to say "I got some 22% bud" rather than "I got some 220 mg/g flower." But for oils and edibles where you're measuring doses? Mg/g makes way more sense. You're taking 10 milligrams of THC, not 1% of something.

 

Most packages show both now anyway. Smart move. Everyone gets the number that makes sense to them.

 

Of course. THC just gets all the attention because... well, it gets you high.

 

But CBD? Measured in mg/g. CBG? Same thing. CBN, CBC, THCV - every single cannabinoid gets the mg/g treatment. Labs test for all of them (at least the main ones) and put those numbers right on the certificate of analysis.

 

This is huge for people who actually know what they're looking for. Want anxiety relief without the high? Find something with 150 mg/g CBD and less than 1 mg/g THC. Need help with inflammation? Look for products high in CBG - maybe 30-40 mg/g.

 

The real magic happens when you start mixing ratios. A 1:1 product with 100 mg/g THC and 100 mg/g CBD hits totally different than pure THC. Some people swear by 2:1 CBD to THC for daytime use. Others want 20:1 for pure medical benefits without any psychoactive effects.

 

Minor cannabinoids are having a moment too. CBN for sleep - you'll see products advertising 10 mg/g CBN specifically. THCV for energy and appetite suppression - products might have 5-15 mg/g. Each one gets measured, labeled, and marketed based on these exact numbers.

 

Even terpenes get the mg/g treatment, though usually in smaller amounts. Limonene at 8 mg/g, myrcene at 12 mg/g - it all adds up to the full profile of what you're consuming. The more you know about these numbers, the better you can dial in exactly what works for your body.
