CBD sparkling water on the shelf at Sainsbury's for £2.50. Five years ago that sounded illegal. Today it's wedged between the kombucha and the alcohol-free gin, looking perfectly ordinary. Trip, Goodrays, Intune, OTO. The cans are beautiful. The claims are bold. Calm. Focus. Sleep. Relaxation.
But what's actually in the can? Is it legal where you live? Does the CBD do anything? And why does flavoured sparkling water cost more than a pint of milk?
We looked at the law across five countries, the science, and the price tag.
The legal picture: it depends where you are
FoodNavigator - CBD in food and drink: Inside the regulation holding it back
The short answer: it depends entirely on where you live. CBD drinks sit in a different legal category in almost every major market.
| UK | US | EU | Canada | Australia | |
|---|---|---|---|---|---|
| Legal to sell? | Yes, with Novel Food application | Grey area (state-dependent) | Technically requires approval, rarely enforced | Only through licensed cannabis retailers | Pharmacy-only (low dose) |
| Regulator | FSA | FDA (federal), plus state laws | EFSA | Health Canada | TGA |
| THC limit | 1mg per container | 0.3% delta-9 (changing to 0.4mg total THC by Nov 2026) | 0.2% in plant material | Regulated under Cannabis Act | Prescription or Schedule 3 |
| CBD daily limit | 10mg (advisory) | No federal guidance | 2mg proposed by EFSA (2025) | No specific limit | Up to 150mg (pharmacy) |
| Supermarket availability | Yes (Sainsbury's, M&S, Tesco) | Some states only | Limited, mostly specialist | No (cannabis retail only) | No |
| Approval status | First authorisations expected mid-2026 | FDA has not approved CBD in food | EFSA paused assessments in 2022 | No separate CBD framework | TGA Schedule 3 pathway exists |
United Kingdom
CBD was classified as a Novel Food in 2019. Any product containing it needs pre-market authorisation from the Food Standards Agency. The FSA maintains a public list of CBD products linked to valid applications. If a product isn't on that list, it shouldn't be on the shelf.
The rules: every CBD food or drink product must have a validated Novel Food application. Products must not exceed 1mg of THC per container. And the FSA advises a maximum daily intake of 10mg CBD for healthy adults.
That 10mg guidance is advisory, not legally enforced. But it matters. A single can of Goodrays contains 30mg of CBD, three times the FSA's recommended limit. Trip contains 15mg. Even Intune at 10mg hits the ceiling in one serving.
The first formal Novel Food authorisations are expected in mid-2026, after the FSA opened public consultations in late 2025. Until then, the market operates in a grey zone: technically regulated, practically tolerated.
United States
The US situation is genuinely confusing. Hemp-derived CBD became federally legal under the 2018 Farm Bill, but the FDA has never approved CBD as a food or drink ingredient. The only FDA-approved CBD product is Epidiolex, a prescription epilepsy medication.
This means CBD drinks exist in a regulatory gap. Some states allow them freely, others restrict or ban them. And a major change is coming: Congress passed Section 781 in late 2025, which from November 2026 will redefine hemp products by total THC content (capped at 0.4mg per container), potentially reclassifying many existing CBD products as controlled substances.
European Union
The EU also classifies CBD as a Novel Food, but progress has been even slower than the UK. More than 100 applications have been submitted to the European Food Safety Authority (EFSA). Only 19 have been reviewed. None have been approved. EFSA paused all CBD assessments in 2022, citing insufficient safety data.
In 2025, EFSA proposed a provisional limit of just 2mg per day for a 70kg adult. That's one-fifth of the UK's already conservative 10mg guidance, and would make most current CBD drinks non-compliant. CBD drinks are available across Europe, but in a legal limbo that makes the UK look well-regulated by comparison.
Canada
CBD is legal but regulated under the Cannabis Act, which means it can only be sold through licensed cannabis retailers. You won't find Trip in a Canadian supermarket. There's currently no pathway for CBD to be sold as a regular food or health product. CBD drinks exist, but they're sold alongside recreational cannabis products, not in the soft drinks aisle.
Australia
Australia takes the most restrictive approach among English-speaking countries. CBD was historically prescription-only. The Therapeutic Goods Administration (TGA) has since created a Schedule 3 pathway allowing pharmacists to sell low-dose CBD products (up to 150mg per day) without a prescription. But the quality and purity standards are extremely strict, and CBD drinks as casual supermarket purchases simply don't exist there.
What does the science say?
MDPI - The Impact of Cannabidiol Treatment on Anxiety Disorders
This is where it gets honest.
CBD has genuine pharmacological properties. It's not snake oil. The prescription medication Epidiolex (approved by both the US FDA and UK MHRA) is used for severe epilepsy at doses of 5-20mg per kilogram of body weight per day. For a 70kg adult, that's 350-1,400mg daily. Clinical studies showing benefits for anxiety and sleep have typically used doses of 150-600mg.
A can of Trip contains 15mg. That's roughly 2-10% of the dose used in studies that showed measurable effects.
One widely cited case series of 72 adults found that anxiety scores decreased in 79% of participants and sleep improved in 67% within the first month. Promising. But these patients were taking 25-175mg of CBD daily in capsule form, not sipping a peach and ginger sparkling water.
There's also the bioavailability problem. When you drink CBD, your digestive system breaks down a significant portion before it reaches your bloodstream. Oral bioavailability is estimated at 6-19%. So that 15mg in your can might deliver 1-3mg to your system.
A systematic review of CBD for anxiety disorders found that while preclinical evidence is encouraging, the human evidence remains limited, with small sample sizes and inconsistent dosing. Researchers noted a likely minimum therapeutic threshold of around 300mg for a single treatment.
The honest summary: CBD probably does something useful at high doses. Whether it does anything meaningful at the doses found in a sparkling drink is, at best, unproven.

Why does a can cost £2.50?
GOV.UK - Testing for CBD in novel foods
Fair question. It's sparkling water with some flavouring and a few milligrams of hemp extract. So where does the money go?
Extraction. Getting CBD from hemp isn't like squeezing an orange. CO2 extraction, the gold standard method, requires specialist equipment operating at high pressure and precise temperatures. It produces clean, consistent CBD isolate, but the kit is expensive and the process is slow.
Compliance. A Novel Food application costs serious money. Toxicology studies, stability testing, manufacturing analysis, third-party lab verification. The application fee alone is £580 in the UK, but the full dossier of safety data can cost tens of thousands to compile. Every batch needs certificates of analysis confirming CBD content and THC levels.
Testing. Each production run must be independently tested. The UK Government Chemist has published specific guidance on CBD testing in novel foods. Brands need to verify CBD and THC levels plus check for heavy metals, pesticides, and microbial contaminants.
Scale. CBD drinks are a niche within a niche. Smaller production runs mean higher per-unit costs for ingredients, canning, and distribution.
Branding. Let's be honest. CBD drinks are marketed as wellness products, not soft drinks. The packaging is beautiful, the positioning is premium, and the pricing reflects that.
For context, a bottle of CBD oil containing 500mg of CBD costs around £20-£30. That's 4-6p per milligram. A can of Trip with 15mg costs about £2.50, roughly 17p per milligram. You're paying a significant premium for the convenience and the fizzy water.
Are they worth trying?
Grocery Gazette - What's next for CBD? How Goodrays aims to stand out
Here's what people miss: these are genuinely nice drinks, CBD or not.
Trip's elderflower mint is crisp and refreshing. Goodrays make a peach and passion fruit that's properly tasty. Intune's pomegranate and ginger has real bite. They're well-made, low-calorie beverages that happen to contain hemp extract.
If you're reaching for one instead of a glass of wine on a Tuesday evening, that's a good swap regardless of whether the CBD does anything. The ritual of opening something that feels a bit special has value. The placebo effect is real, measurable, and nothing to be snobbish about.
But manage your expectations. If you're buying CBD drinks specifically for anxiety relief or better sleep, the evidence says the doses are almost certainly too low to deliver clinical effects. You'd need to drink 10-20 cans of Trip to match the lowest dose shown to help with anxiety in trials. Please don't do that.
The brands worth trying: Trip is the UK market leader with 88% market share and the widest supermarket distribution. Goodrays is the fastest-growing CBD brand by value and stocked in most major supermarkets. Intune offers interesting flavour combinations at a slightly lower price. OTO takes a lower-dose approach at 5mg, more aligned with the FSA's guidance.
Buy one because you fancy trying something different. Don't buy a case expecting it to fix your sleep. If the CBD does something for you, brilliant. If it doesn't, you've still got a nice drink. At £2.50, you've spent less than a pint at the pub. Somewhere in that gap is where CBD drinks actually live: pleasant, slightly overpriced, and more honest than most wellness products if you read the small print.
