What information is required on Minnesota cannabis labels?

Minnesota cannabis labels under Chapter 9810 must include: THC and CBD content per serving and per package, batch number, testing laboratory name, mandatory warnings (21+ only, keep from children, impairment/driving, pregnancy), manufacturer name and license number, manufacturing/packaging date, expiration date, ingredients list, allergen warnings, serving size information, and the universal cannabis symbol.

What does THC percentage mean on cannabis flower labels?

THC percentage on flower labels represents the THC content by weight. For example, a gram of 20% THC flower contains roughly 200mg of THC. However, not all of that THC is absorbed when consuming — bioavailability varies by method (smoking, vaping, etc.). For edibles and beverages, THC is listed in milligrams, which is a more direct measure of dose.

How do I check if a Minnesota cannabis product was lab tested?

Look for the testing laboratory name, batch number, and test pass confirmation on the label. Many Minnesota products include QR codes that link to the full certificate of analysis (COA) showing detailed results for potency, pesticides, heavy metals, and contaminants. You can also contact the manufacturer with the batch number to request COA documentation.

What is a good starting THC dose for beginners?

For beginners, start with 2.5-5mg of THC. This is considered a standard beginner dose and will produce noticeable but manageable effects. Minnesota THC beverages (5-10mg per can) and low-dose edibles are ideal starting products. Wait at least 2 hours before consuming more, as edibles can take 30-90 minutes to take effect.

Why Labels Matter

Cannabis labels are your first line of defense as a consumer. Unlike many consumer products, cannabis potency varies significantly from product to product and batch to batch. Reading labels helps you:

Control your dose — know exactly how much THC and CBD you are consuming
Verify safety — confirm the product has been lab-tested
Track batches — identify specific production runs in case of recalls
Make informed choices — compare products by potency, ingredients, and manufacturer

What Minnesota Labels Must Include

Under Chapter 9810 rules adopted by the Office of Cannabis Management (OCM), all cannabis products sold in Minnesota must display:

1. THC and CBD Content

The most important information on any cannabis label:

Total THC per serving — how many milligrams of THC in one dose
Total THC per package — the total THC in the entire container
CBD content — per serving and per package
For flower: THC percentage by weight (e.g., "22% THC")

Understanding THC Percentages

For flower, THC is listed as a percentage by weight. A gram of 20% THC flower contains roughly 200 mg of THC. However, not all of that THC is absorbed when smoking — bioavailability varies by method. For edibles and beverages, THC is listed in milligrams, which is a more direct measure of the dose you will consume.

2. Batch Number

Every product carries a unique batch number that ties it to a specific production run. This enables:

Traceability — tracking the product from seed to sale
Recall capability — if a batch fails testing, all products from that batch can be identified
Lab result verification — you can look up the batch's certificate of analysis

3. Lab Testing Results

Labels must indicate that the product has passed required lab testing. Look for:

The name of the testing laboratory
Confirmation that the batch passed all required tests
A batch number or QR code linking to the full certificate of analysis (COA)

For details on what labs test for, see our Lab Testing page.

4. Warnings and Safety Information

Minnesota requires several mandatory warnings on cannabis labels:

"For use only by adults 21 and older"
"Keep out of reach of children"
Warning about impairment and driving
Warning about use during pregnancy and breastfeeding
Universal cannabis symbol — the standardized symbol indicating the product contains THC

5. Manufacturer Information

Licensee name and license number
Manufacturing date and/or packaging date
Expiration date or best-by date
Ingredients list (for edibles, beverages, and manufactured products)
Allergen warnings where applicable

6. Serving Size Information

For edibles and beverages:

Number of servings per package
THC per serving in milligrams
Total THC per package in milligrams

Understanding Potency

Potency is the single most important factor in determining your experience. Here is a general guide:

THC Dose	Experience Level	Expected Effects
1–2.5 mg	Microdose	Mild relaxation, subtle mood lift, minimal impairment
2.5–5 mg	Beginner	Noticeable effects, mild euphoria, some impairment
5–10 mg	Standard	Moderate effects, definite impairment, typical recreational dose
10–25 mg	Experienced	Strong effects, significant impairment
25+ mg	High tolerance	Very strong effects, not recommended for most consumers

QR Codes and Digital Labels

An increasing number of Minnesota cannabis products include QR codes on their labels. Scanning the QR code with your phone typically links to:

The full certificate of analysis (lab test results) for that specific batch
Detailed terpene profiles
Strain information and growing details
Manufacturer's website and product information

HF 4203 has been proposed to standardize QR code usage across all Minnesota cannabis products, potentially making digital label access a universal requirement.

Hemp-Derived vs. Cannabis-Derived Labels

Minnesota has two types of THC products with different labeling standards:

Feature	Cannabis Products (Dispensary)	Hemp-Derived THC (Retail)
Regulator	OCM (Chapter 9810)	OCM (Chapter 342)
THC limits	Varies by product type	5 mg/serving, 50 mg/package (edibles); 10 mg/beverage
Lab testing	Required	Required
Child-proof packaging	Required	Required
Sold at	Licensed dispensaries	5,345 licensed retailers

Tips for Reading Labels

Check THC Per Serving First

The most important number on any label is THC per serving. This tells you exactly how much THC you will consume in one dose. Ignore the package total until you know the per-serving amount.

Count the Servings

A package of gummies might contain 10 pieces at 5 mg each (50 mg total). Eating the whole bag is very different from eating one gummy. Always check the serving count.

Look for the Batch Number

If you find a product you like, note the batch number. You can look up the full certificate of analysis and try to find the same batch again. If a product does not agree with you, the batch number helps identify it.
