CBD water is a new product to have come on to the UK market in recent months. There are a number of UK brands offering both plain water with CBD and some flavoured with terpenes.
CBD or cannabidiol is a phytochemical – a plant-produced compound. It is produced by the herb Cannabis sativa. CBD is not psychoactive and has in fact been shown to counter some of the psychoactive effects of other compounds seen in C. sativa.
Chemically speaking, CBD is to a large extent non-polar, much like other oils and fats, as well as aldehydes and some other solvents. This means that each molecule has an even electromagnetic charge, – it’s not stronger at either end. This can be compared with water, which is polar. The molecules of water are positive at one end and negative at the other. This can be demonstrated by rubbing an inflated balloon against a wool sweater to give it an electromagnetic charge and holding this near a gently running water tap. If the balloon has been charged properly and the stream of water is small enough, the water will deflect towards the balloon. Oils, alkanes, and aldehydes, on the other hand, would not deflect.
Why all this information? Polar and non-polar substances generally will not mix. Think of vinegar (polar) and oil (non-polar) in a salad dressing. To mix effectively, they need an emulsifier, such as mustard, or soap. As CBD is non-polar, water is polar, and neither mustard nor soap sound appealing in a usually refreshing drink, there has to be another way to mix the CBD into the water.

Of the UK companies currently manufacturing CBD Water, many claim to make use of nanotechnology to break down the CBD into nanoparticles, and infuse it into the purified water. These processes are evidently trade secrets, as no further information is given.
On Earth, at least, water is an essential component of life. Every living organism needs water to perform essential cellular functions. From bacteria and archaea through plants, fungi, and mammals like us. Without a regular supply of water, functioning would be impossible. Humans are thought to need anywhere between two and six litres of water a day, depending on temperature, humidity, activity level, and water loss. Many people do not consume enough water, and this can lead to both short- and long-term health issues.
The combination of CBD – a promising addition to diet and lifestyle – and water – the most essential of substances – appears to offer an interesting and healthy product. It is already being added to diets and fitness regimes across the United Kingdom and the world over, and a large number of types, both flavoured and not, are available.
