How Much THC Does Your Blunt Really Contain
Ever stared at a blunt labeled '24% THC' and wondered if it'll deliver relaxation or tomorrow's regret story? This guide reveals the simple math that turns confusing percentages into predictable experiences.

Is a 24% THCa blunt something that will make for a nice, relaxing smoke? Or will it knock you on your behind, leaving you groggy for tomorrow's work or adventure?
Here's the simple math that ends the mystery: multiply grams by percentage, then divide by four to estimate what you'll actually absorb.
That intimidating 24% suddenly becomes a manageable number you can compare to your familiar 10mg edible benchmark.
No more late-night panic searches. No more trusting budtenders who seem to pull numbers from thin air. Just straightforward calculations that turn abstract percentages into predictable experiences you control.

Calculate THC in Any Blunt Using Basic Math
The formula that changes everything fits on a napkin: weight in grams × THC percentage = total milligrams. Let's run through three real examples that cover what you'll actually encounter.
Start with a mini blunt holding 0.5 grams at 18% THC. Multiply 500mg (remember, 1 gram equals 1,000mg) by 0.18 to get 90mg total THC. Simple multiplication, you learned in grade school.
Now consider Mood's Traditional Blunt: 1 gram of flower testing at 24% THCa. That's 1,000mg × 0.24 = 240mg theoretical THC. Mood backs this math with third-party lab certificates, removing the guesswork from your calculations.
For those eyeing infused options, imagine 1.5 grams enhanced with concentrates. The base flower might test at 20% (300mg), but kief or oil additions push the total past 400mg. The math stays the same; only the numbers get bigger.
One crucial detail: THCa becomes more potent when heated. For precision, multiply THCa percentages by 0.877, though using the percentage as-is gives reasonable estimates for most purposes.
What Actually Reaches Your Bloodstream
Here comes the revelation that transforms those scary numbers into something manageable: you only absorb about one-quarter of a blunt's total THC content.
Scientists consistently find that smoking delivers 20-30% of available cannabinoids to your bloodstream. The rest goes up in sidestream smoke, gets destroyed by heat, or simply doesn't make it through your lungs.
Think of it like making coffee: you put four scoops in the filter, but only one scoop's worth ends up in your cup.
This changes everything about those calculations above. That 240mg Traditional Blunt? Divide by four and you're looking at roughly 60mg absorbed, spread across your entire smoking session.
Suddenly, the math aligns with experiences you already understand.
Mood provides dry-weight potency on every package and certificate of analysis. They give you the total THC content, leaving this crucial absorption calculation in your hands. Now you know the missing piece that makes sense of it all.
Cannabis Potency Ranges You'll Actually Find
Modern cannabis isn't your parents' pot. Today's strains routinely test between 15-30% THC, with some exotic cultivars pushing even higher. Understanding these ranges helps you pick blunts that match your tolerance.
Entry-level strains hover around 15-18% THC, perfect for social situations where you want to stay functional. Mid-range options at 18-22% deliver noticeable effects without overwhelming most users.
The heavy hitters start at 25%, including famous strains like Girl Scout Cookies (25-28% THC) and Death Star (consistently over 25%).
Mood's rotating selection captures this full spectrum, though specific strains change with harvest cycles. That's why their category pages stay current while individual strain availability shifts with the seasons.
Here's what the numbers miss: a well-grown 18% strain often delivers better experiences than poorly cultivated 25% flower.
Smaller amounts of premium cannabis can match or exceed larger quantities of average product, making quality as important as percentage.
Your Blunt in Edible Terms
Finally, a comparison that makes sense: smoking 1 gram at 20% THC roughly equals five 10mg gummies spread over 30 minutes. This translation between smoking and eating helps you predict effects using experiences you already know.
The key difference? Edibles hit all at once after an hour, while smoking delivers THC gradually with each puff. You feel the first effects within minutes, peak around 30 minutes, then taper off over 2-3 hours.
This gradual curve explains why the same total THC feels different when smoked versus eaten.
Are blunts higher in THC than joints? Yes, simply because they hold more flower.
Blunts typically pack 1-2 grams compared to joints at 0.3-0.75 grams. More flower means more total THC, though the percentage stays the same.
For those socializing scenarios that keep you up at night, remember that sharing cuts individual intake dramatically. Four people splitting that 240mg blunt? Each person absorbs roughly 15mg over the session, well within most comfort zones.
Why Your Roll Matters More Than You Think
Every variable in your rolling technique affects how much THC you actually get. Loose rolls let precious smoke escape between puffs.
Pack too tight and restricted airflow creates harsh, uneven burns that waste cannabinoids. Uneven grinding creates hot spots that torch THC before it reaches your lungs.
This variability explains why identical-looking blunts can hit completely differently. One might burn perfectly for 20 minutes while another races through in 10, taking your THC with it. Even experienced rollers struggle with consistency, especially when using different papers or working with sticky, resinous flower.
Mood's pre-rolled options eliminate these variables entirely. Machine-perfect packing ensures consistent airflow and burn rate every time. The wrap material is the same weight and density.
When calculating THC content, removing rolling variables means your math actually matches your experience.
Want to check your own rolls? Try the airflow test: before lighting, take a gentle pull through the unlit blunt. You should feel slight resistance, like sipping a thick milkshake. Too easy means it's loose; too hard means reroll time.

When Blunts Pack Extra Surprises
Infused blunts throw standard calculations out the window. Adding kief, hash oil, or distillate doesn't just add THC; it multiplies potency in ways that catch users off guard.
Consider this: a gram of 20% flower (200mg THC) dusted with kief testing at 40% THC. Just a quarter-gram of kief adds another 100mg, pushing your total to 300mg before you even light up. That's a 50% potency jump from what looks like a light dusty coating.
Concentrates amplify this effect even more dramatically. A thin line of distillate can add 50-100mg of near-pure THC to any blunt. Some infused options combine multiple additions: flower wrapped in concentrate-dipped paper, rolled in kief. These combinations can push totals past 500mg, rivaling the strength of entire chocolate bars.
Mood offers both standard and enhanced options, clearly labeling when products include these potency boosters.
The math stays the same, but pay attention to all ingredients listed, not just the base flower percentage. Pre-rolled blunts with infusions command premium prices for good reason.
Getting Your Hands on Lab-Tested Options
Thanks to the Farm Bill's hemp provisions, Mood ships lab-tested THCa products across the United States.
This federal bill means you can access dispensary-strength products even in prohibition states, as long as the Delta-9 THC stays below 0.3% before heating.
The practical benefits go beyond legal access. Free shipping over $99 means you can stock up without leaving home. The 100-day guarantee provides a safety net for trying new strains. Discreet packaging keeps nosy neighbors from knowing your business.
What matters most for THC calculations? Every Mood product links to third-party lab results showing exact cannabinoid percentages. No guessing, no "trust me, bro" claims from dealers. Just verified numbers you can use in your calculations with confidence.
While 17 states have proposed restrictions on high-THCa hemp, current federal law keeps these products flowing.
Mood's website automatically adjusts available products based on your location, ensuring you only see what ships to your state.
