Buy Hemp CBD Oil Online: What to Check Before You Pay

Hemp CBD oil sold online falls under the 2018 Farm Bill when the plant carries 0.3 percent THC or less on a dry weight basis. That number applies at harvest, not always to the bottle at your door. Read the lab report before you buy.

Step 1: Find the batch number and COA

Sellers that follow good practice post a certificate of analysis (COA) from a third-party lab. The COA lists batch number, test date, cannabinoid profile, potency, residual solvents, pesticides, heavy metals, and microbials. A COA older than 12 months may not match the current batch. A generic COA with no batch number is marketing, not testing.

Step 2: Compare milligrams per bottle and per serving

Labels state total CBD in the bottle, not per dose. A 30 mL bottle with 1000 mg holds about 33 mg per mL. A 30 mL bottle with 3000 mg holds about 100 mg per mL. A standard dropper holds about 1 mL. Check both numbers. Price per milligram varies by brand, so divide total mg by total price.

Step 3: Know the extract type

Workplace drug tests detect THC metabolites. Full spectrum use can cause a positive result. Isolate and broad spectrum carry less risk. No product carries zero risk.

Step 4: Check carrier oil and extraction method

Common carriers are MCT oil from coconut, hemp seed oil, and olive oil. MCT absorbs faster for some users. Hemp seed oil contains no cannabinoids by itself. Supercritical CO2 and ethanol are the two main extraction methods. Both work. Solvent residue appears in the COA when the process fails.

Pitfalls to avoid

Before you order

Confirm the seller ships to your state. State rules on CBD differ, and some restrict sales. Read the return policy and the stated ship time. Save the batch number and order confirmation. If a seller cannot answer questions about the COA, buy from another seller.
