Prerequisites
This guide covers hemp-derived cannabis products, including CBD flower, vapes, tinctures, and edibles shipped under federal hemp rules. It does not cover recreational marijuana in states where a licensed dispensary is required.
- A delivery address in a state or country where the product is legal to receive
- Proof of age, since most sellers require 18+ or 21+ at checkout and at delivery
- A payment method with a dispute path, such as a credit card
Start with the jurisdiction, not the product page
Hemp must stay at or under 0.3% THC on a dry weight basis under the U.S. Domestic Hemp Production Program. Any seller shipping a product above that threshold across state lines is selling a controlled substance, whatever the site says. Check your state's rules on hemp-derived intoxicants before you add anything to a cart, because several states cap total THC per package or ban specific product types outright.
If a store cannot state which state it ships from and which states it refuses, treat that as a sign of a seller who has not done the compliance work.

Verify the product, not the branding
Certificate of analysis
A real COA is a lab report tied to a specific batch number, not a generic PDF reused across a whole catalog. Match the batch number on the report to the batch number on the package you receive. The report should list cannabinoids individually, plus tests for pesticides, heavy metals, residual solvents, and microbials.
Testing lab and method
Look for a lab name you can check against state licensing lists. Independent labs measure cannabinoid content with methods like HPLC, and reference materials exist to validate that measurement. A potency number with no lab name and no date is a marketing claim.
Potency and serving size
Compare total cannabinoids per container, not per gram. A 3.5 g jar of flower at 18% total cannabinoids carries far more material than a 10 mg gummy, and dosing advice for one does not transfer to the other.
How to place the order
- Confirm the product type is legal in your state.
- Open the COA and check the batch number, test date, and full panel results.
- Compare price per milligram of cannabinoids across at least three sellers.
- Read the shipping policy for states the seller will not ship to.
- Check the return policy for opened versus sealed products.
- Pay by credit card so you keep a chargeback option.
- Save the order confirmation and the COA file.
- Inspect the package on arrival and match the batch number to the saved COA.
Parameters to compare
- Total THC: the number that determines legal status, not the delta-8 or CBD figure alone
- Full panel testing: cannabinoids plus contaminants, not potency only
- Batch specificity: a report that names the batch you are buying
- Price per milligram: the only fair cross-seller comparison
- Shipping restrictions: a clear state list
- Customer support: a phone or email that answers before purchase
Pitfalls that cost money
- COAs with no batch number, no date, or a lab that cannot be verified
- Health claims that promise to treat or cure a condition, which sellers cannot legally make for these products
- Gift card or peer-to-peer payment requests, which remove your dispute path
- Prices far below the market rate per milligram, often a sign of untested material
- Listings that hide total THC behind a large CBD number
After checkout
Keep the packaging and the COA until you have used the product. If the batch number does not match the report, stop and contact the seller in writing before opening the seal. A seller who cannot produce a matching lab report on request is telling you what the next order will look like.
