On the label, check four things: THC milligrams per can, any other cannabinoids and their ratio, whether the pack is a single strength, and a certificate of analysis (COA) that matches the product. Before you buy, make two separate checks: that the seller verifies you are 21+, and whether it ships to your state. A brand's shipping list shows where it chooses to ship. It is not a legal opinion, so check the rules where you live.
On the label
| Label check | What to look for | How OUI answers it |
|---|---|---|
| 1. THC per can | A milligram figure, not just "light" or "strong" | 5mg or 10mg hemp-derived Delta-9 THC per can |
| 2. Other cannabinoids | Whether CBD or others are included, and how much | CBD equal to THC (1:1): 5 + 5 or 10 + 10 |
| 3. Pack strength | Whether a pack mixes strengths | Every 4-pack is a single strength |
| 4. Lab results | A COA you can open that names the product | COAs at mavbev.com · How to read a COA |
Also read the ingredient list and nutrition panel on the can.
Before you buy
| Purchase check | Why it's separate from the label |
|---|---|
| Age verification (21+) | It's part of buying, not something printed on the can. A seller that doesn't verify age is a warning sign. |
| Shipping eligibility | It depends on the seller's policy, your state, and sometimes the product strength. A seller's state list is not a legal determination. Rules are changing, so verify your local law. |
OUI's shipping list: where we ship. Eligibility varies by state and strength.
Why these checks matter
- Milligrams let you compare strengths. Adjectives don't.
- A single-strength pack means every can in it holds the same amount.
- A COA is the evidence behind the label. Match the product name and batch.
