CBD Buyer’s Guide: How to Choose CBD and Pay a Fair Price

By Mark Gillilan, founder of Kyoto Botanicals. Updated .

Buying CBD should not take a spreadsheet. This guide puts everything I have built to help you choose in one place: side by side comparisons of the gummies and oils people actually buy, a calculator for what CBD really costs you per month, what the December 11 hemp ban means for your CBD, and the checklist I would use on any product, ours or anyone else's.

CBD and the December 11 Hemp Ban

Starting December 11, 2026, a hemp product with more than 0.4 mg of total THC in the whole container no longer counts as hemp under federal law. That catches most full spectrum CBD on the market, so it is worth understanding before you buy.

How to Tell if a CBD Product Is Worth Buying

I have been in the CBD industry since 2017, first running marketing at Charlotte's Web and then building Kyoto Botanicals. This is the checklist I would use on any CBD product.

  1. Do the cost per mg math. Price divided by the total mg of CBD in the package. A big discount on a weak product can still cost more per mg than a small discount on a strong one.
  2. Check the serving size. Some brands list two gummies as one serving, so 25 mg per serving can mean 12.5 mg per gummy.
  3. Match the lab report to your lot number. One old report on a website for every batch is not the same thing as a report for the batch in your hand.
  4. Look for ND, then check the detection limit. Non-detect (ND) means the lab found no THC down to its detection limit. The limit times the weight of the container is the worst case.
  5. Know the total THC per container. After December 11, 2026 the number that matters is milligrams of total THC in the whole container, and it has to be 0.4 or less.
  6. Check the regular price. A real sale is a discount off the price a brand charges the rest of the year, not off a compare-at price nobody ever paid.
  7. Read the fine print on shipping. A great price with a high free shipping line is not a great price on a small order.

Which CBD Product to Start With

When people ask me where to start, here is what I tell them.

  • New to CBD: gummies. There is nothing to measure and every gummy is the same.
  • An evening routine: an oil. You can adjust the dose a little at a time. I take a tincture right after dinner and have for about 10 years.
  • A sore spot after a run or a workout: a cream, right on the spot. I use ours after every run.

For the amount, start at 15 to 30 mg a day for a week. If it is not doing what you want, add 10 mg and hold that for another week, and keep going until you find your amount. Consistency matters more than the first dose you pick.

CBD Buyer's Guide FAQ

How do I choose a CBD product?

Start with the form that fits your day: gummies are the easiest place to start, an oil works well for an evening routine because you can adjust the dose a little at a time, and a cream is for the spot that is sore. Then compare cost per mg, check the THC on the lab report and make sure the lab report matches your lot number.

What is a fair price for CBD?

Compare cost per mg, which is the price divided by the total CBD in the product. Across the 22 gummies and oils we track from 8 brands, one-time prices ran from 2 to 8 cents per mg when we checked them on October 24, 2026. Ours are between 5.2 and 5.5 cents per mg.

How much CBD should I start with?

What I tell people is to start at 15 to 30 mg a day for a week. If it is not doing what you want, add 10 mg and hold that for another week, and keep going until you find your amount. Talk to your doctor first if you take other medications.

What is the difference between full spectrum, broad spectrum and isolate?

Full spectrum CBD keeps some THC on purpose. Broad spectrum is made to remove THC while keeping other parts of the plant. Isolate is CBD on its own. Only the lab report tells you how much THC is really in the product.

Is CBD still legal after December 11, 2026?

Yes, as long as the whole container has 0.4 mg of total THC or less. Most full spectrum CBD carries more THC than that, so it will no longer count as hemp under federal law. Check your state and local rules too.

How do I read a CBD lab report?

Match the lot number on the report to the one on your product. Look at total CBD, then at THC. If THC says ND (non-detect), check the detection limit, because the worst case is that limit times the weight of the whole container. Also look for tests on pesticides, heavy metals, solvents and microbes.

This page is general information, not legal or medical advice. Hemp and CBD rules also differ by state and city, so always check your local and state regulations. Talk to your doctor before starting CBD, especially if you take other medications.
