How to Identify Dosage on THC Labels: A Step-by-Step Guide

To identify dosage on THC labels, find the "THC per serving" value in milligrams, then confirm the "servings per container" to calculate total potency. If only total THC is listed, divide that number by the number of servings. For edibles, a standard single serving is 10 mg THC. Always check for THCA and convert it using a 0.877 multiplier to get total THC.

Step-by-Step: Reading THC Dosage on Labels

1. Locate the "Serving Size" and "Servings Per Container" fields on the label.
2. Find the "THC per Serving" value in milligrams.
3. Divide "Total THC" by "Servings Per Container" if only total THC is listed.
4. Check for "THCA" on the label.
5. Multiply the THCA milligram amount by 0.877.
6. Add the converted THCA to the listed THC milligrams to get total THC.
7. Identify the "Potency" or "Lab Tested" section.
8. Compare the "THC per Serving" to the 10 mg standard edible dose.
9. Verify the batch number and expiration date.

Common Label Terms and What They Mean

Understanding these terms helps you avoid confusion when comparing products from different brands or states.

• THC: The primary psychoactive cannabinoid.
• THCA: The acidic precursor to THC; it becomes THC when heated.
• Total THC: The sum of THC and the converted THCA.
• Serving Size: The recommended amount for one dose, often 1 piece or 1 gummy.
• Servings Per Container: How many servings are in the entire package.
• Potency: The concentration of THC, usually shown as a percentage or mg per unit.

How to Calculate Dosage from Total THC

If a package says "Total THC: 100 mg" and "Servings Per Container: 20", each serving has 5 mg THC. If you want a 10 mg dose, you would consume two servings. Always start with a low dose, especially if you are new to cannabis edibles.

Why Labels Can Be Confusing

State regulations vary. Some states require THC per serving and per package, while others only require total THC. The FDA does not regulate cannabis like it does food or drugs, so label accuracy depends on state oversight and lab testing. Look for products from licensed dispensaries that provide full lab reports. When buying weed online from top cannabis brands, check that the product listing includes clear dosage information and a link to the COA.
