THE TAKEAWAY

Compare CBD per milliliter and per labelled serving. Bottle size alone does not describe concentration.

Separate the ingredients

A typical CBD oil combines a CBD ingredient with a carrier. Check the ingredient list for the carrier, flavorings, and any other cannabinoids. “Hemp oil” on its own is too vague to establish how much CBD a product contains.

Compare concentration

Divide the labelled total milligrams of CBD by the bottle volume in milliliters. For example, a hypothetical 600 mg bottle containing 30 mL has a labelled concentration of 20 mg/mL. This is label arithmetic, not a recommended dose. It does not verify the actual contents.

Oil and tincture are not always used consistently

Sellers sometimes use the terms interchangeably. Read the ingredients and directions rather than assuming the name tells you the solvent or how to use it. Do not put an oral oil into a vaping device.

Make a small product checklist

Save the label, batch number, report, and stated serving. Ask whether the report covers the bottle’s batch and whether cannabinoid results use compatible units. Product testing by the Food Standards Agency shows why chemical measurements matter. [1] Bring that information to your clinician before making a decision about use.
