How to Calculate THC Per Serving with Distillate RSO or Nano THC
Calculating THC per serving involves a formula with two steps: calculate total milligrams in your batch, then divide by the number of servings.
Written by Lorien Strydom

You're holding a distillate syringe, RSO, or nano THC shot and need to know how many milligrams of THC end up in each serving. The formula has two steps: calculate total milligrams in your batch, then divide by the number of servings.
Here's a complete example. One gram of 85% THC distillate contains 850mg total THC (1g × 0.85 = 850mg). Divide that 850mg across 20 brownies and you get 42.5mg per brownie.
These calculations give you estimates, not guarantees.
Real kitchens have heating losses, infusion inefficiencies, and individual biology differences that affect your results. We'll show you how to account for these variables throughout this guide.
Nano THC changes timing but not the math—effects arrive faster while the milligrams stay the same. Identical amounts can feel different based on when you eat, what you ate, and how your liver processes cannabinoids.

How to Calculate THC Per Serving from Concentrates
Concentrate calculations follow a two-step process. First, multiply grams by THC percentage to get total milligrams. Second, divide total milligrams by servings to find potency per piece.
Start by converting the percentage to a decimal. An 85% distillate becomes 0.85. Then multiply: 1 gram of distillate × 0.85 = 850mg total THC.
Working with RSO and Thick Concentrates
RSO (Rick Simpson Oil) uses the same formula with one adjustment. Measure by weight, not volume, because RSO's thickness makes eyeballing unreliable.
Example: 1g RSO at 70% THC = 700mg total THC. Mix that into 100ml coconut oil and you get 7mg per milliliter. Add 15ml (one tablespoon) to your recipe and you're adding 105mg THC.
Calculating Milligrams Per Milliliter for Liquids
When working with oils or tinctures, divide total milligrams by total volume. A 500mg THC infusion in 50ml of oil gives you 10mg per milliliter. If your recipe calls for 20ml of that oil, you're adding 200mg THC.
Keep a conversion reference handy. One tablespoon equals 15ml, one teaspoon equals 5ml. Small measurement errors with concentrates create large potency swings.
These formulas give you theoretical maximums. Real results will be lower due to heating and infusion losses we'll cover in the next section.

Flower and Tincture Calculations Work the Same Way
Cannabis flower requires an extra consideration before applying the same two-step method. The THCa listed on testing certificates becomes more potent when exposed to heat during cooking or smoking.
Start with the THCa percentage from your COA . Apply the two-step formula: total cannabinoid content times efficiency, then divide by servings.
Example with Flower
Seven grams of flower at 20% THCa contains 1,400mg total (7g × 0.20 = 1,400mg). After accounting for heating efficiency of roughly 85%, you have approximately 1,190mg of activated THC. Infuse that into 100ml of alcohol for a tincture and you get about 11.9mg per milliliter.
These numbers shift based on your heating method and duration. Lower temperatures preserve more cannabinoids but require longer exposure times.
Tincture Shortcuts
Commercial tinctures already list milligrams per milliliter on the label. Multiply that concentration by the milliliters in your recipe. A tincture with 10mg/ml used at 5ml adds 50mg to your batch.
Mood provides third-party testing certificates for all products showing exact cannabinoid percentages. This transparency lets you verify the numbers you're using in calculations.
Account for Real Kitchen Losses
Perfect math meets imperfect reality in home kitchens. Your 850mg of distillate won't deliver 850mg in finished edibles because the heating process and infusion method introduce losses.
Industry estimates suggest the heating process captures 80-90% of potential THC depending on temperature and duration. Infusion transfer operates at 85-95% efficiency as cannabinoids stick to containers and plant material.
Combined, these factors create 70-85% overall efficiency.
Applying Efficiency Ranges to Your Calculations
Take that 850mg distillate example. At 70% efficiency, you get 595mg in the finished product. At 85% efficiency, you retain 722mg. Dividing by 20 servings gives you 30-36mg per piece instead of the theoretical 42.5mg.
This range explains why identical recipes produce different results. Temperature fluctuations, mixing thoroughness, and equipment differences all affect your efficiency percentage.
Where Cannabis Gets Lost
Cannabinoids left in plant material after straining account for the largest losses with flower-based infusions. Oil that coats your bowl, spatula, and storage container removes another 5-10%. Incomplete heating conversion happens when temperatures stay too low or duration runs too short.
Higher-potency starting materials like distillate and RSO minimize these losses because you're not filtering plant material. Pure concentrates eliminate one failure point in the process.
Conservative estimates serve you better than optimistic ones. Use the lower end of efficiency ranges (70-75%) for your first batch, then adjust based on actual effects.
Why Timing and Meals Change How It Feels
The same milligram amount produces wildly different experiences based on when and what you eat. Your digestive system, not the THC content, drives most of this variation.
Edibles take 45-120 minutes to produce initial effects because cannabinoids travel through your digestive system before reaching your bloodstream.
Effects continue building for another hour after you first notice them. The full peak often arrives 90-120 minutes after consumption.
Food Timing Affects Absorption
Empty stomach consumption accelerates onset to around 45 minutes but creates intensity spikes that can feel overwhelming.
Full stomach consumption delays effects up to 2 hours but smooths the intensity curve across a longer duration.
Fatty foods increase cannabinoid absorption significantly. THC binds to fat molecules, so eating your gummies with peanut butter or after a meal with healthy fats amplifies effects. Protein-heavy meals slow absorption instead.
The Two-Hour Rule
Wait at least two hours before consuming more. People who take a second serving after one hour experience both servings hitting simultaneously around the two-hour mark. The result becomes overwhelming when patience would have prevented it.
Your liver converts THC into 11-hydroxy-THC, a metabolite more potent than what you consumed. This conversion process explains why edibles feel different from smoking or vaping the same amount. The intensity and duration both increase through liver processing.
Active effects last 4-8 hours for most people, with some experiencing light residual feelings into the next day. Plan accordingly—take your first serving when you have a clear schedule.
When Edibles Barely Work Regardless of Amount
Approximately 10-15% of people have genetic variations in liver enzymes that prevent normal oral THC processing.
For these individuals, edibles produce minimal effects regardless of the amount consumed.
The primary enzyme responsible is CYP450. Genetic differences in how this enzyme functions mean some people break down THC before it reaches the bloodstream in active form. No calculation fixes this biological reality.
Alternative Consumption Methods
If you've tried 20mg or more with no effects, consider different formats. Tinctures held under the tongue for 60-90 seconds bypass digestive processing through sublingual absorption.
Vapes and flower deliver cannabinoids through your lungs, avoiding liver conversion entirely.
Nano THC products sometimes work when standard edibles don't because the smaller particle size changes absorption pathways. The technology won't overcome severe enzyme differences, but it's worth attempting before abandoning oral consumption.
This isn't about doing something wrong or needing higher amounts. Biology determines your response to edibles more than any calculation can account for. Recognizing this pattern early prevents wasted money and frustration from escalating amounts that won't work.

Nano THC Speeds Onset Without Changing the Math
Nano-emulsion technology breaks THC into smaller particles that your body absorbs faster. Onset drops from 45-120 minutes down to 30-45 minutes. The milligram calculation stays identical—only the timeline shifts.
Fifteen milligrams of nano THC produces the same intensity as 15mg of standard THC. The difference appears in how quickly you feel effects and how the experience builds. Nano products create a faster climb to peak intensity with a slightly shorter overall duration.
How Nano Technology Works
Standard THC particles measure 1,000-5,000 nanometers. Nano-emulsification reduces them to 10-200 nanometers. These smaller particles pass through your digestive system barriers more readily, entering your bloodstream faster.
Mood's Hero Dose Rapid Onset Gummies demonstrate this technology with consistent 30-45 minute onset times. Each gummy contains 15mg Delta-9 THC and 15mg Delta-8 THC in nano-emulsified form.
The Wait Rule Still Applies
Faster onset doesn't eliminate the need for patience. Wait at least two hours before taking more, even with rapid-onset products.
Your body's peak response still arrives after the initial effects begin, and stacking servings creates the same overwhelming experience whether the onset is fast or standard.
Nano products help people who want predictable timing for specific activities. Take one 45 minutes before dinner and effects arrive as you're finishing your meal. This predictability removes guesswork from social situations.
Turn One Good Result Into Consistent Batches
Finding your perfect serving size once doesn't guarantee repeatable results without controlling variables. Standardize your approach to minimize batch-to-batch variation.
Take edibles at the same time relative to meals. If you found 10mg worked perfectly after dinner, replicate that timing. Empty stomach trials will feel stronger even with identical milligrams.
Keep Notes on Your Experiences
Record onset time, peak intensity, total duration, and overall comfort level. Note what you ate beforehand and when. After 3-5 sessions with the same amount and timing, you'll see your personal pattern.
Rate intensity on a 1-10 scale where 4-6 feels pleasant and controllable. This subjective measurement helps you communicate with others and adjust your next attempt.
"Too strong" means different things to different people—numbers create clarity.
Plant Material Variability
Even with precise calculations, natural batch variance occurs because cannabis flower isn't pharmaceutical-grade uniform. The 20% THCa flower you bought last month might test at 18% or 22% in the next batch.
Check COA dates when available—fresher testing reflects current product more accurately.
Concentrate potency remains more stable than flower because the extraction process standardizes cannabinoid content. Pre-made edibles eliminate this variable entirely through batch testing and quality control.
Skip the Math with Labeled Milligrams and COAs
Every calculation in this guide becomes unnecessary when you choose products with exact milligram labeling backed by third-party testing. The calculator has already been applied—you're buying the answer instead of solving the equation.
15mg Delta-9 THC gummies contain exactly 15mg per piece, verified by independent labs. 30mg gummies deliver 30mg with the same certainty. You're purchasing predictability, not just cannabinoids.
Third-Party Testing Verification
Certificates of Analysis from accredited laboratories show exact cannabinoid content, not estimates. Each batch gets tested for potency, contaminants, pesticides, and heavy metals.
These results appear on product pages and via QR codes on packaging.
Compare that certainty to your kitchen math. You estimated 85% distillate potency, guessed at 75% efficiency, hoped your mixing distributed evenly, and assumed your oven temperature matched the dial. Each assumption compounds into your final result.
Mood offers milligram amounts from 5mg microdose options up to 30mg hero servings.
This range lets you find your perfect amount without making or wasting entire batches during calibration.
When Convenience Beats Craft
Some people enjoy the process of making edibles—measuring, infusing, baking becomes part of the ritual. Others want reliable effects without the work, variability, or kitchen smell that comes with DIY infusion.
Pre-made products make sense for people with limited time, those still finding their optimal serving size, or anyone who values consistency over craft.
You can always make infused foods occasionally while relying on tested products for daily use.
Practical Guardrails for Comfort
Even with perfect calculations, experiences occasionally feel more intense than expected. Biological variability, meal timing, or tolerance changes can shift your response to a familiar serving size.
If effects feel stronger than you'd like, find a comfortable space and focus on steady breathing. Sip water slowly—hydration helps but chugging can upset your stomach. Bland snacks like crackers or toast can help ground you.
What to Expect
Enhanced senses, time moving differently, and deep relaxation are typical effects, not signs something's wrong. These sensations gradually fade over 4-6 hours as your liver processes the cannabinoids.
Having entertainment ready helps. Queue up familiar movies or music before consuming so you're not making decisions during peak effects.
Many people find that CBD products provide balance if available, though this represents personal preference rather than medical intervention.
Important Disclaimers
All calculations in this guide represent educational estimates, not medical advice. We cannot predict how any amount will affect your specific biology. Individual responses vary dramatically based on genetics, tolerance, metabolism, and dozens of other factors.
Consult licensed healthcare professionals for personal health questions. We're not medical or mental health authorities and cannot provide consumption guidance.
Hemp-derived THC appears on standard drug tests despite federal compliance status. Testing protocols detect THC metabolites regardless of the product's legal classification.
You Now Have the Numbers and the Context
You can calculate per-serving THC content from distillate, RSO, flower, or tinctures using the two-step method: total milligrams in your batch, then divide by servings. Apply 70-85% efficiency ranges to account for heating and infusion losses.
You understand why timing, meals, and individual biology shift experiences even when milligrams stay constant. Nano THC speeds onset without changing intensity.
Some people won't respond to oral consumption regardless of amount due to genetic enzyme variations.
Consistency comes from two paths. Master every variable—standardize timing, control temperature precisely, keep detailed notes, and accept natural batch variance.
Or choose products where third-party labs handle the calculations and verification.
