The Golden Rule of Edible Dosing
Edible Dosing Chart
| Dose (mg THC) | Level | Effects | Best For |
|---|---|---|---|
| 1-2.5mg | Micro-dose | Subtle mood lift, reduced anxiety, enhanced focus. Many people cannot tell they took anything. | First-timers, daily microdosers, anxiety management |
| 2.5-5mg | Low | Mild euphoria, gentle relaxation, slightly enhanced senses. You know you took something. | Beginners, social situations, light stress relief |
| 5-10mg | Standard | Clear euphoria, noticeable body relaxation, altered perception, appetite increase. | Occasional users, evening relaxation, moderate pain |
| 10-25mg | Strong | Strong euphoria, significant impairment, heavy body relaxation, couch-lock likely. | Experienced consumers, chronic pain, sleep |
| 25-50mg | Very Strong | Intense psychoactive effects, strong sedation, significant impairment for hours. | High-tolerance daily consumers only |
| 50-100mg+ | Extreme | Overwhelming for most. Extended duration (8-12+ hours). Not for inexperienced users. | Very high tolerance, certain medical protocols |

Browse MenuHow Edible Dosing Works (The Science)
Edibles hit differently than smoking for one reason: 11-hydroxy-THC. When you eat THC, your liver converts it into this metabolite before it reaches your brain. 11-hydroxy-THC is 2-3 times more potent than regular delta-9 THC and crosses the blood-brain barrier more efficiently.
This is why a 10mg edible can feel significantly stronger than smoking 10mg of THC. The molecule is different by the time it reaches your brain. It is also why onset takes 30-90 minutes (your liver needs time to process it) and why the duration is 4-8 hours (11-hydroxy-THC has a longer half-life than inhaled THC).
For a deeper dive on this process, including a timeline of how edibles move through your body, see our how long edibles take to kick in guide.
Factors That Affect Your Ideal Dose
Tolerance Level
The single biggest factor. A daily user might need 25-50mg for the same effect a beginner gets from 5mg. Tolerance builds quickly with regular edible use.
Body Weight
Heavier individuals may need slightly higher doses, but the relationship is moderate — not proportional. A 200lb person does not need double the dose of a 100lb person.
Metabolism
Faster metabolisms convert THC to 11-hydroxy-THC more quickly, meaning faster onset and potentially more intense peak. Slower metabolisms have a gentler, more gradual experience.
Food in Stomach
Edibles on an empty stomach hit faster and harder. On a full stomach, onset is slower but the experience is smoother. Eating a meal with healthy fats before an edible can improve absorption.
Product Type
Nano-emulsified edibles (like THC drinks) absorb faster than traditional gummies. Chocolates absorb differently than gummies. The carrier affects how quickly THC reaches your liver.
Individual Biology
Genetics play a role. Some people have more active CYP enzymes in their liver (which convert THC to 11-hydroxy-THC), making them more sensitive to edibles. This is not something you can predict without trying.
How to Calculate Homemade Edible Doses Manually
If you are making edibles from dispensary flower, here is the formula:
The Formula
Step 1: Flower weight (g) × 1,000 = total mg
Step 2: Total mg × THC% (as decimal) = raw THC mg
Step 3: Raw THC mg × 0.88 = decarbed THC mg
Step 4: Decarbed mg × 0.70 = actual available THC mg
Step 5: Available mg ÷ servings = mg per serving
Example: An Eighth (3.5g) at 20% THC, Making 10 Brownies
3.5g × 1,000 = 3,500mg total
3,500mg × 0.20 = 700mg raw THC
700mg × 0.88 = 616mg after decarb
616mg × 0.70 = 431mg available
431mg ÷ 10 brownies = ~43mg per brownie
43mg per brownie is a strong dose. Most people should eat half a brownie (21mg) or a quarter (11mg) if they do not have high tolerance.
The 0.88 decarb factor and 0.70 extraction factor are industry estimates. Your actual results depend on your decarb method (see our decarboxylation guide) and infusion technique. Sous vide and dedicated machines get closer to 0.90+ decarb efficiency. Butter extraction can range from 0.60-0.80 depending on time and temperature.
Common Dosing Mistakes
Mistake: Taking More Because You Don't Feel It Yet
Fix: Edibles take 30-90 minutes. Set a 2-hour timer. If you feel nothing after 2 full hours, THEN consider taking another small amount.
Mistake: Assuming Smoking Tolerance = Edible Tolerance
Fix: They are different pathways. 11-hydroxy-THC from edibles is more potent than inhaled THC. Even heavy smokers should start edibles at 5-10mg.
Mistake: Not Reading the Label
Fix: A 100mg package of 10 gummies means 10mg each. The package is 10 doses, not one. Read servings per container AND mg per serving.
Mistake: Eating on an Empty Stomach Without Knowing
Fix: Empty stomach = faster, stronger onset. Eat a meal first for a smoother experience, or know that empty-stomach edibles will hit harder and faster.
Mistake: Mixing Edibles and Alcohol
Fix: Alcohol increases THC absorption and amplifies effects unpredictably. Choose one or the other, especially when dialing in your dose.

Get DirectionsFrequently Asked Questions
How many mg of edibles should I take?
For first-time users, start with 2.5-5mg of THC. For occasional users (a few times per month), 5-10mg is a standard dose. For regular users (weekly), 10-25mg is typical. For daily consumers with high tolerance, 25-50mg or higher may be needed. Your ideal dose depends on weight, metabolism, tolerance, and the type of experience you want. Always start low and increase gradually over multiple sessions.
How do you calculate edible dosage from flower?
To calculate homemade edible dosage: (1) Multiply flower weight in grams by 1,000 to get milligrams. (2) Multiply by the THC percentage (as a decimal). (3) Multiply by 0.88 for decarboxylation efficiency. (4) Multiply by 0.70 for extraction/infusion efficiency. (5) Divide by number of servings. Example: 3.5g flower at 20% THC = 3,500mg x 0.20 x 0.88 x 0.70 = 431mg total, divided by 10 servings = 43mg per serving.
Does body weight affect edible dosage?
Body weight has a moderate effect on edible dosage, but it is not the primary factor. Tolerance level and individual metabolism matter more. That said, individuals over 200 lbs may need slightly higher doses to achieve the same effects, while individuals under 120 lbs may be more sensitive. The relationship is not linear — doubling your weight does not mean doubling your dose. A 200-lb person with no tolerance should still start at 2.5-5mg.
Why do edibles affect me differently than smoking?
When you eat THC, your liver converts it into 11-hydroxy-THC, which is 2-3 times more potent than regular THC and crosses the blood-brain barrier more efficiently. This is why a 10mg edible can feel much stronger than smoking the equivalent amount of THC. The onset is also slower (30-90 minutes vs 1-5 minutes) and the duration is longer (4-8 hours vs 2-4 hours). This is why experienced smokers should still start with low edible doses.
What is the standard edible dose?
The industry-standard single serving of a THC edible is 10mg in most states, including New Jersey. However, 10mg is a moderate dose that may be too strong for beginners or infrequent users. Many brands now offer 2.5mg and 5mg options specifically for newcomers. A good rule: if you are not sure, 5mg is the new standard starter dose. You can always take more next time, but you cannot take less once you have swallowed it.
How accurate is an edible dosage calculator?
An edible dosage calculator provides a reasonable starting estimate, but individual responses to THC vary significantly based on genetics, endocannabinoid system activity, food intake, and other factors that no calculator can account for. Use calculator results as a starting point, not a guarantee. Start at or below the recommended dose, track how you feel, and adjust from there over multiple sessions. For homemade edible calculations, actual THC content can vary by 10-20% from calculated values.
