What Is THC, and Why Does Potency Matter?

Let’s start at square one. THC, short for tetrahydrocannabinol, is the compound responsible for the heady, euphoric effects cannabis is known for. It's the main cannabinoid people look at when talking about how “strong” a product is.

A product’s THC content doesn’t tell the whole story—but it’s a solid baseline. Higher THC means more powerful effects, especially when it comes to flower and vapes. If you’re new to cannabis or getting back into it after a break, knowing the THC level is key to dialing in the right experience.

How THC Levels Are Measured

THC concentrations are typically shown as a percentage of the cannabis product’s weight.

For flower, this means the amount of THC per gram of plant matter. A strain testing at 25% THC has 250mg of THC per gram. For concentrates, the numbers can look way higher—think 70% to 95%—because it’s just the extracted oil.

With edibles, the label usually shows the total milligrams of THC per serving and per package. For example: 10mg per gummy, 100mg total in a 10-count.

One important note: Labels often list both THC and THCa. THCa is non-psychoactive until it's heated, which is when its effects are amplified. Lab tests may include both numbers, but you’ll mostly want to look at the total THC figure, especially if you're smoking or vaping different cannabis strains.

THC Percentages in Flower

Cannabis flower usually falls into these general potency ranges based on cannabis industry standards:

• Low THC: Under 10%

• Moderate THC: 10%–20%

• High THC: 20%–30%

• Very High THC: Over 30%

Back in the day, anything above 15% was considered potent. But now? You’ll find tons of high-THC cannabis products hovering around 25%, and even some going above 30% with lab tests to prove it.

But remember—higher doesn’t always mean better. Some people prefer the smooth, mellow vibes of a 14% strain over getting blasted by something with 32%.

What’s Considered High THC in Cannabis Flower?

Generally, any strain over 20% THC is considered high potency. Once you hit the 25%+ range, you’re in strong territory. And above 30%? That’s top-shelf territory—rare, premium, and not for the faint of heart.

If you’re smoking THCa flower, that number usually reflects the THCa content, which increases in effect when heated—so a THCa strain testing at 28% is going to hit like high-THC regular flower.

High THC in Concentrates and Vapes

When you’re dabbing or vaping, the numbers get even higher.

Here’s a quick breakdown:

• Live Resin / Sauce: 60%–80% THC

• Distillate Vapes: 80%–95% THC

• Diamonds / Isolates: 90%+ THC

• Rosin: 70%–85% THC

This is concentrated cannabis, so even a tiny dab can go a long way. If you’re used to smoking flower, hitting a 90% vape cart might feel like jumping from a chill pool into a hot tub on high.

We offer everything from mellow blends to ultra-potent hitters. If you're chasing max potency, keep an eye on our live resin and high-THCa cart drops.

What About THC in Edibles?

Edibles are a whole different beast. Here, THC is measured in milligrams, not percentages.

Typical edible strengths look like:

• Low Potency: 2.5mg–5mg per serving

• Standard Potency: 10mg per serving

• High Potency: 20mg–50mg per serving

• Extra-High Potency: 100mg+ per serving

For most people, 5-10mg is a solid starting point. If you’ve got a higher tolerance, or you’re looking to blast off, there are stronger options. Just know: edibles take longer to kick in, but the effects tend to last longer and hit harder.

We carry edibles across the spectrum—including some wild 100mg single-serving gummies for the bold.

How to Approach High-THC Products

High-THC weed isn’t better by default—it’s just stronger. How much you enjoy it depends on your tolerance, your vibe, and what kind of experience you’re after.

A few tips for handling high-potency cannabis:

• Start slow. This is especially true for edibles and concentrates. You can always take more—but you can’t untake what you just ate.

• Don’t chase numbers only. Terpenes, product type, and even your mood all play a role in the experience.

• Set the scene. Chill environment, snacks on deck, and no big plans can help you enjoy the ride.

At Mood, we test everything for potency and purity, so you know exactly what you’re getting into. Whether you're all about those 30%+ THCa buds or looking to ease in with something lighter, we've got you covered.

Final Thoughts on THC Potency

High THC means high potential—but it’s not one-size-fits-all. Some folks chase those sky-high numbers, while others find their sweet spot in the teens. No wrong answers here—just preferences.

As always, we’re here to supply the goods and keep the vibes right. Whether you’re into THCa flower, live resin vapes, or classic edibles, our lineup covers the full spectrum of potency and format.
