The 1mg Rule, Explained for Buyers
UK law caps controlled cannabinoids at one milligram per container — not per serving, not per bottle size. How the limit works, and why the FSA's public list is the practical tool for shoppers.

Ask why a UK CBD product is legal to sell and the answer runs through two documents most shoppers never read. One is the Misuse of Drugs Regulations; the other is a spreadsheet on the FSA’s website. Both are worth two minutes of your time.
One milligram, per container
Some cannabinoids — THC most famously — are controlled drugs in the UK. A CBD product can be sold lawfully only if it stays within the exemption rules, and the headline condition is blunt: no more than 1mg of a controlled cannabinoid per container. Not per serving, not per millilitre, not scaled to the size of the bottle. The whole container gets one milligram, whether it holds 10ml or 100ml.
The practical consequence is the interesting part. A bigger bottle, or a stronger formula, has to be proportionally cleaner of controlled cannabinoids to fit under the same fixed ceiling — which is why high-strength full-spectrum products are the hardest place in the category to get the chemistry right. As of this writing, the container rule is the rule.
Why the FSA list is your tool
Here is the buyer’s problem: you cannot verify any of that from a label. No shopper owns a lab. What you can check, in about a minute, is the FSA’s public list of CBD food products — the register of products linked to credible novel-food applications and permitted to stay on sale while those applications are assessed. Search the product, not just the brand: the list works at product level, and a company can have some products on it and others not.
Be clear-eyed about what the list is. Inclusion is not an approval, and the FSA does not present it as one — it means the product is attached to an application the regulator considers credible enough to assess. That sounds like faint praise until you consider the alternative: a product on no list, attached to no application, accountable to no process.
The two-minute routine
Before you check a price, check the list. If a product isn’t on it, ask the brand why — there can be boring administrative answers, but the brand should know its own answer. Then look for a batch lab report, which is where the 1mg question actually gets answered, container by container.
None of this requires trust in marketing. That is rather the point.
