🍪 Edible Dosage Calculator
Calculate precise THC and CBD mg per serving for homemade edibles, cannabutter, and infusions
Calculate Your Dosage
Amount of flower or concentrate in grams
Typical flower: 10-30%, concentrates: 60-90%
How many cookies, brownies, etc. will you make?
Typical efficiency when properly decarboxylating is 85-90%
Your Edible Dosage
Dosage Guidance:
⚠️ Start Low, Go Slow
Edibles can take 30 minutes to 2 hours to take effect and last 4-8 hours. If you're new to edibles, start with 2.5-5mg THC and wait at least 2 hours before consuming more.
Understanding Edible Dosing
What is Decarboxylation?
Decarboxylation is the process of heating cannabis to activate THC and CBD. Raw cannabis contains THCA and CBDA, which aren't psychoactive. Heating converts these to active THC and CBD. This happens automatically when smoking, but must be done separately for edibles (typically 240°F for 40 minutes in an oven).
Why Edibles Are Different
Edibles must be digested and metabolized by your liver before entering your bloodstream. This process takes 30 minutes to 2 hours. Your liver converts THC into 11-hydroxy-THC, which is more potent and crosses the blood-brain barrier more efficiently. This is why edibles produce stronger, longer-lasting effects (4-8 hours) compared to smoking (1-3 hours).
Dosage Guidelines by Experience
Beginners: 2.5-5mg (microdose, minimal effects). Light users: 5-10mg (mild effects, relaxation). Moderate users: 10-20mg (clear effects, strong relaxation). Experienced users: 20-50mg (strong euphoria, potential for couch-lock). Very experienced: 50mg+ (intense effects, only for those with high tolerance).
Why This Calculator Matters
Homemade edibles can be unpredictable. This calculator helps ensure consistent dosing by accounting for cannabis potency, decarboxylation efficiency, and serving size. Proper dosing prevents uncomfortable experiences from taking too much and ensures therapeutic or recreational effects from taking the right amount.
How to Use This Calculator
- Weigh your cannabis flower or concentrate in grams
- Find the THC/CBD percentage on your product label or from lab testing
- Enter the amount of cannabis and its potency percentages
- Enter the number of servings your recipe will make (e.g., 24 cookies, 12 brownies)
- Select your decarboxylation efficiency (88% if properly decarbed, 100% for distillate)
- Click "Calculate Dosage" to see mg per serving
- Follow the dosage guidance based on your experience level and desired effects
Frequently Asked Questions
How accurate is the edible dosage calculator?
This calculator provides accurate estimates based on standard decarboxylation efficiency (85-90%). Actual potency can vary based on decarb time/temperature, cannabis quality, and homogeneity of mixing. For most accurate results, use lab-tested cannabis with known THC/CBD percentages.

What is a safe edible dosage for beginners?
For beginners, start with 2.5-5mg THC. This is considered a microdose and allows you to gauge your tolerance. Wait at least 2 hours before consuming more, as edibles can take 30 minutes to 2 hours to take effect and last 4-8 hours.
