This calculator helps you determine the appropriate dosage of medical marijuana according to Health Canada guidelines. It accounts for your weight, THC content, and desired serving size to provide a safe and effective recommendation.
How to Use This Calculator
To use this calculator effectively:
- Enter your weight in kilograms
- Select your preferred serving method (edible, tincture, or vaporized)
- Input the THC content percentage of your product
- Specify the desired THC dose in milligrams
- Click "Calculate" to get your recommended serving size
Note: This calculator provides general guidance. Always consult with a healthcare professional for personalized medical marijuana advice.
Formula Used
The calculator uses the following formula to determine the appropriate serving size:
Serving Size (grams) = (Desired THC Dose × 10) ÷ (THC Content × 100)
For example, if you want 25mg of THC and your product contains 10% THC:
Serving Size = (25 × 10) ÷ (10 × 100) = 250 ÷ 1000 = 0.25 grams
This formula accounts for the dilution of THC in different serving methods while providing a safe starting point for your medical marijuana regimen.
Worked Example
Let's walk through a complete example:
- Weight: 70kg (though weight isn't directly used in this calculation)
- Serving Method: Edible
- THC Content: 15%
- Desired THC Dose: 30mg
Using the formula:
Serving Size = (30 × 10) ÷ (15 × 100) = 300 ÷ 1500 = 0.2 grams
This means you should consume 0.2 grams of your 15% THC edible to get approximately 30mg of THC.
Interpreting Results
The calculator provides several key pieces of information:
- Recommended Serving Size: The amount of product you should consume
- THC Content: The percentage of THC in your product
- Desired Dose: The amount of THC you want to ingest
- Serving Method: How you'll be consuming the product
Remember that individual responses to medical marijuana can vary. Start with a lower dose and gradually increase as needed while monitoring your effects.
| THC Content | Desired Dose (mg) | Recommended Serving (grams) |
|---|---|---|
| 10% | 25 | 0.25 |
| 15% | 30 | 0.2 |
| 20% | 20 | 0.1 |
