PlainCBD is an independent information site about CBD. We explain what CBD is, how to read a product label, how to check a lab report and what the law says, in plain English. We don’t make CBD products, and we don’t sell them.

Why PlainCBD exists

CBD is easy to buy and hard to understand. Shelves and websites are full of big promises. Labels use confusing numbers. And the product inside the bottle does not always match what the label says.

That last point is not just a hunch. In a 2017 study published in JAMA, researchers tested 84 CBD products sold online. Only about 31% had a CBD amount close to what the label claimed. About 43% contained more CBD than labeled, and about 26% contained less. THC, the compound in cannabis that causes a “high”, was found in 18 of the 84 products.

The FDA has also tested CBD products and says many did not contain the levels of CBD they claimed. The agency also warns that some CBD products are marketed with unproven medical claims.

We started PlainCBD so people can cut through that noise and make calm, informed choices.

What we do

  • Explain CBD. What it is, what research does and doesn’t show, and the known safety concerns.
  • Decode labels. Total mg, mg per mL, serving sizes, “full spectrum”, “broad spectrum” and “isolate”.
  • Read lab reports. How to find and check a certificate of analysis (COA) for a product.
  • Track the law. Hemp and CBD rules vary by state and are changing. We explain them in plain terms and link to official sources.

Our plain rules

  1. No miracle claims. CBD is not a cure-all. If the evidence is weak or missing, we say so.
  2. Sources linked. We cite government agencies and peer-reviewed research, and we link them so you can check for yourself.
  3. Lab reports first. We care more about what a lab found in the bottle than what the marketing says.
  4. Paid placements clearly labeled. If we ever earn money from a link or a post, we tell you. See our Advertising Disclosure.

Important: PlainCBD provides general information, not medical or legal advice. Talk to a doctor or pharmacist before using CBD, especially if you take any medication. See our CBD & Medical Disclaimer.
