Cannabis Tea: What It Is and the UK Legal Position
Cannabis tea infused with THC is illegal to make or possess in the UK under the Misuse of Drugs Act 1971. CBD tea using legal CBD oil or hemp flowers is fully legal, widely sold and has no psychoactive effect. This page explains what cannabis tea is, how it works in the body and what the law says.
THC cannabis tea is illegal to produce, possess or supply in the UK. Cannabis is a Class B controlled substance under the Misuse of Drugs Act 1971. Infusing cannabis into a beverage constitutes production of a controlled drug. Possession carries up to five years imprisonment; production and supply carries up to fourteen years. CBD tea made with compliant CBD oil or hemp is fully legal and widely available.
Cannabis tea is a hot or cold beverage made by infusing cannabis plant material — or a cannabis extract — into water, typically with a fat source such as milk or coconut oil to aid the absorption of fat-soluble cannabinoids. It is one of the oldest forms of cannabis consumption, with historical records of medicinal cannabis beverages in traditional South Asian and East Asian medicine. In the UK, cannabis tea containing THC is illegal to produce. CBD tea using hemp-derived CBD flowers or CBD oil is legal and commercially available in health food shops, pharmacies and online. The two should not be confused: CBD tea has no psychoactive effect; THC cannabis tea does.
What Cannabis Tea Is and Its History
Cannabis tea has a long history predating modern smoking culture by centuries. Traditional Ayurvedic medicine used bhang — a preparation of cannabis leaves simmered in milk with spices — for ceremonial and medicinal purposes across South Asia. Similar cannabis beverage traditions existed in various forms across Central Asia, the Middle East and parts of Africa long before cannabis smoking became widespread in the 20th century.
Modern cannabis tea typically involves either steeping the plant material directly in hot water with a fat source, or adding a cannabis extract (such as a tincture or infused oil) to a regular tea beverage. The key challenge is that THC is not water-soluble — it is fat-soluble — meaning plain hot water alone extracts only very small amounts of cannabinoids from plant material. Effective extraction requires the presence of a fat (milk, cream, butter or coconut oil) to bind the cannabinoids and carry them into the beverage.
How Cannabis Tea Works in the Body
Why fat is needed
THC is lipophilic — it dissolves in fats rather than in water. Steeping cannabis in plain water produces a very weakly infused beverage with minimal cannabinoid content. Adding full-fat milk, cream, butter or coconut oil to the brewing process allows THC to bind to these fats, producing a significantly more potent infusion. This is the same principle as the fat requirement for cannabis edibles generally.
Onset timing
Like all orally consumed cannabis, cannabis tea must be digested and metabolised by the liver before THC enters general circulation. Onset typically takes 30 minutes to 90 minutes, with effects peaking between 1 and 3 hours after drinking. This is slightly faster than solid edibles for some people because liquid passes through the digestive system more quickly than solid food, but the variability between individuals remains significant.
Duration and intensity
The effects of cannabis tea last between 4 and 8 hours — considerably longer than smoked or vaped cannabis. As with other edibles, the liver converts delta-9-THC to 11-hydroxy-THC, a more potent and longer-lasting metabolite. Many users report that cannabis tea produces a more body-centred, relaxing effect than the same amount smoked, with a gentler onset than concentrated solid edibles due to the dilution in liquid form.
The overconsumption risk
The delayed onset carries the same overconsumption risk as any cannabis edible. Consuming a second cup of tea because no effect has been felt after 30 to 60 minutes often results in an overwhelming combined dose when both servings take effect simultaneously. In regulated cannabis markets where tea is legal, starting with half a serving and waiting at least two hours is standard harm reduction guidance.
UK Legal Position: THC Tea vs CBD Tea
THC cannabis tea — illegal in the UK
Any beverage containing THC cannabis — whether made from cannabis flowers, leaves, stems or extracts — is illegal to produce, possess or supply under the Misuse of Drugs Act 1971. Cannabis is a Class B controlled substance. Production carries up to fourteen years imprisonment. There is no personal use, small quantity or domestic production exemption in UK law.
CBD tea — fully legal in the UK
Tea made with legal CBD products is fully legal. This includes CBD oil added to regular tea, dedicated CBD tea bags (hemp flower blends within legal THC limits), and CBD-infused herbal tea products. CBD tea is widely sold in UK supermarkets, health food shops and online. It contains no meaningful psychoactive compounds and will not produce a high of any kind.
CBD hemp flower tea — nuanced legal area
Dried CBD hemp flowers (sold as aroma products or CBD flower) occupy a more complex legal position. The flowers themselves are permitted if derived from an approved hemp strain with less than 0.2% THC at harvest. However, brewing them into a tea technically involves preparing a cannabis-derived product, which sits in a grey area. Purchasing pre-prepared CBD tea bags from established brands with clear certification is the most straightforward legal option.
In regulated international markets
In Canada and several US states, cannabis-infused beverages including THC tea are commercially produced and sold under strict regulatory frameworks requiring standardised THC content per serving (typically 5 to 10mg), clear labelling, childproof packaging and age restriction. The UK has not legalised recreational cannabis products in any form.

Onset time for cannabis beverages — slightly faster than solid edibles due to liquid digestion, but still far slower than inhalation

CBD Tea: The Legal UK Alternative
CBD tea is one of the most accessible and widely available CBD products in the UK. Ready-made CBD tea bags using hemp flower blends or CBD extract are sold in high street health food shops, pharmacies, major supermarkets and online retailers. They combine the familiar ritual of making a cup of tea with the potential wellness benefits of CBD including relaxation, ease and sleep support.
CBD tea can also be made simply at home by adding a few drops of quality CBD oil to any regular tea. The oil disperses in the hot liquid and CBD is absorbed through the digestive system. Onset is 30 to 90 minutes and effects are gentle and non-intoxicating. Adding a splash of whole milk helps CBD absorption due to the fat content, mirroring the fat-solubility principle of all cannabinoid products.

The traditional South Asian cannabis beverage bhang is made from cannabis leaves and flowers simmered in milk with spices. It has been consumed in parts of India for centuries and is still legally sold at licensed government bhang shops in certain Indian states. Cannabis beverages have a far longer recorded history than cannabis smoking, which became widespread only in the early 20th century. Understanding this historical context helps explain why cannabis tea appears in so many different cultural traditions worldwide.

Frequently Asked Questions
Is cannabis tea legal in the UK?
THC cannabis tea is illegal in the UK. Any tea or beverage infused with cannabis containing THC is covered by the Misuse of Drugs Act 1971 in the same way as any other cannabis product. CBD tea made with compliant CBD oil or certified hemp products is fully legal. The legality depends entirely on whether the product contains THC above the permitted trace level.
Why do you need milk or butter in cannabis tea?
THC and other cannabinoids are fat-soluble, not water-soluble. Simply steeping cannabis in hot water extracts very little THC because THC does not dissolve readily in water. Adding a fat source — whole milk, cream, butter or coconut oil — provides the lipid medium that cannabinoids need to bind to and dissolve into, producing a significantly more potent and effective infusion.
What does CBD tea do?
CBD tea can produce gentle non-psychoactive effects consistent with CBD generally: a mild sense of relaxation, reduced tension and for some users improved sleep quality at appropriate doses. Effects are subtle rather than obvious and accumulate more meaningfully with consistent daily use than from a single cup. CBD tea will not produce any intoxication, impair driving ability or cause any high of any kind.
How long does cannabis tea take to work?
Cannabis tea works through the same digestive pathway as other edibles. In regulated markets where cannabis beverages are legal, onset is typically 30 to 90 minutes. Drinking on an empty stomach with a fat source in the tea generally produces faster onset than drinking after a full meal. Effects peak at 1 to 3 hours and typically last 4 to 8 hours — significantly longer than inhaled cannabis.
