All Of Your CBD Oil Questions Answered

CBD – The Basics

What is CBD Oil?

CBD oil is a fabulous food supplement rich in cannabinoids and terpenes, which help to bring balance to our bodies and minds by interacting with the endocannabinoid system in our bodies. The benefits of CBD oil are wide and varied and it is sold legally in the UK as a food supplement. The World Health Organisation stipulates that CBD oil is non-toxic, non-addictive and non-psychoactive. You can buy CBD oil from our shop here.

What does CBD stand for?

CBD stands for cannabidiol, which is one of over a hundred different compounds known as cannabinoids.

CBD is known as a non-psychoactive cannabinoid meaning when you take it, you won’t feel high. This unique feature of CBD is what makes it so great and appealing for taking care of ourselves.

Where does CBD Oil come from?

CBD oil is derived from a strain of cannabis plant called hemp sativa. Hemp sativa naturally grows with very low levels of THC, so it is legal in the UK. It contains high levels of CBD (cannabidiol) and over 100 different healthy cannabinoids. CBD and other cannabinoids are not psychoactive or physically addictive.

CBD & Your Body

What is the Endocannabinoid System?

In 1992, Dr. Raphael Mechoulam, an Israeli scientist, discovered that every human and many animals have a system present in their bodies known as The Endogenous Cannabinoid System or Endocannabinoid System. This system is activated by cannabinoids.

Our bodies create cannabinoids, which are used by the endocannabinoid system to maintain balance (homeostasis) in the body. However, unfortunately most of us are unable to create enough of our own cannabinoids and therefore our endocannabinoid system may be out of balance, resulting in poor health.

The endocannabinoid system has often been described as the most important system in the body for maintaining long-term health.

Research suggests that taking CBD oil helps your body to create more of the cannabinoids needed by this system, in turn helping to maintain balance and wellbeing in the body.

What are the benefits of taking CBD Oil?

CBD had been used for many thousands of years until it was unfortunately prohibited in the 20th century due to its connection with cannabis. CBD and hemp are now fully legal in the UK and the EU but sellers of CBD oil cannot make medical claims regarding its benefits.

When hemp and CBD were legalised a few years ago, many people began to take CBD and other cannabinoids extracted from hemp plants to top up their cannabinoid levels and bring more balance to their endocannabinoid systems.

Taking CBD oil helps your body to create more of the cannabinoids that your endocannabinoid system needs to help maintain balance and wellbeing in the body. It is vital to keep this system working well as it helps our immune systems, protects our brains, helps us manage stress and generally keeps our bodies in balance.

Will taking CBD help with my illness?

First of all a disclaimer: UK Home Office regulations prevent us from providing any medical claims regarding CBD’s efficacy. We cannot give any recommended dosages for particular issues.

Having said that, there are thousands of studies published online and if you read the testimonials from our customers you can discover what people are using Bristol CBD oils for and read about their experiences. Please visit uk.trustpilot.com/review/bristolcbd.co.uk to find these reviews.

Does CBD affect sleep?

Some people sleep well on CBD, others don’t. It usually depends on the reason why sleeping is difficult. For some, CBD can help relax the body and mind so that sleeping becomes easier. On the other hand, some people notice an uplifting, energising effect, which could make falling asleep more difficult. Should you notice that falling asleep proves more difficult, then take your last drops of the day some 2-3 hours before sleeping.

Can I take CBD with other medication?

It is wise to check with your doctor before using CBD oil if you are using other medication. According to the World Health Organisation CBD oil is non-toxic, non-addictive and non-psychoactive and there have never been any reported cases of overdoses or serious side effects.

In some studies, certain doses of CBD have been known to temporarily deactivate Cytochrome P450 (CYP450), a class of liver enzymes responsible for the breakdown of some clinically prescribed medications. This can lead to the delayed breakdown and prolonged activity of administered prescription medications (as well as some OTC medications).

While not believed to be life-threatening, it is advisable to pay attention to any changes in health whilst taking medications alongside CBD and always visit your GP if you are concerned about any new symptoms.

Some people already have anomalies in the CYP450 enzyme system, which can impact the way they metabolize CBD, as well as certain medications. For these individuals it may be necessary to re-evaluate the dosage of CBD.

Can I use CBD if pregnant or breastfeeding?

If you are thinking about using CBD oil whilst pregnant or breastfeeding you should consult with your GP.

Can children take CBD?

We do not sell CBD oil to children or anyone under the age of 18. If you are thinking about giving CBD oil to someone under the age of 18 you should consult with your doctor.

How To Take CBD Correctly

What strength CBD should I start with?

If you are new to taking CBD it is wise to start with a low or medium strength CBD oil. If you are a sensitive person, then we recommend you starting with the 3% CBD bottle, although it is perfectly reasonable to start with the 5% CBD bottle.

We recommend starting with the minimal suggested serving on any CBD product and then increase the amount gradually until you reach the results you want.

The World Health Organisation stipulates that CBD is non-toxic, non-addictive, and non-psychoactive and, to date, there are no reports of serious side-effects.

But if you are taking other medication, you should consult with your GP or pharmacist, to check whether there could be any contra-indications.

When you first start taking CBD oils, you should start with a low dose, and start increasing gradually, as per our dosage guide.

How much CBD should I take each day?

Everyone is different; everyone’s body is different. As a result everyone reacts to CBD differently. Some of us are naturally much more sensitive to CBD than others.

With CBD it is important to start with a small dose and build it up slowly. Discover how your body reacts to CBD for a few days before increasing the dose. See our guide below. Some people only need about 10mg of CBD p/day, whereas others find that they might require up to 200mg per day.

CBD Oil is twice as bio-available via the gums, than via the gut – which means that it is absorbed much better when held in the mouth for a minute. Spray or drop the CBD oil into your mouth then close your lips and apply slight suction. This boosts the absorption of the active ingredients through the mucous membrane in the mouth before swallowing.

What is the quickest way to feel the benefits from CBD?

CBD oil is most quickly and readily absorbed via the gums. It is less bioavailable via the gut so if it is swallowed immediately some of the CBD will be lost or absorbed more slowly. Therefore we recommend that people place CBD oil or paste into the mouth and keep it near the gums for a minute before swallowing. You can learn more about CBD oil by visiting our shop here.

I don’t like the taste of CBD Oil. Is there an alternative?

There are two types of full-spectrum CBD oil – dark oil and gold oil. The dark oil contains the dark-coloured plant waxes which have a bitter taste. Some people dislike the bitter taste and so prefer to use the ‘gold’ CBD oil. This gold CBD oil contains the full spectrum of cannabinoids and terpenes but does not contain the dark, bitter plant waxes so the gold oil has a very mild taste.

Some people mix the dark CBD oil with honey or other sweet liquids on a spoon before putting the CBD oil into the mouth. Other people have recommended placing CBD oil onto a sweet or mint before placing it in the mouth and sucking the sweet.

More About Our Products

How do I find out how much CBD is in the bottle?

Every bottle of CBD that we sell has a measured amount of CBD in it. This is calculated based on lab tests which measure the strength of CBD in a batch of oil or paste.

We stipulate on the label of each bottle how much CBD is in each bottle in both total weight and as a percentage.

For example we sell a ‘300mg CBD 10ml bottle’ which is 3% CBD. This means that the bottle contains 300mg of CBD in total and that the CBD is 3% of net weight.

i.e. a 10ml bottle contains a total of 10,000mg of oil and 3% of that is CBD which equals 300mg of CBD. You can buy CBD oil from our shop here.

How do I know that the bottle contains as much CBD as it says on the label?

All CBD products sold in the EU must be laboratory tested. If you buy CBD oil from a shop or website that does not have valid lab tests then you cannot be sure of the actual amount of CBD in the bottle. Our latest lab reports are visible on our website.

Where is your CBD sourced from?

Our CBD oils and pastes are sourced from farms across the EU. We work with a network of people to ensure that we have access to a broad range of CBD oils of different strengths. Some people prefer gold oils, which are more readily available in Northern Europe, whereas other people prefer darker whole-plant oils, which are more common to Southern or Eastern Europe.

Is your CBD Oil organic?

Yes. We only sell CBD oil extracted from organic hemp sativa grown far away from main roads, with no pesticides or chemicals. Our growers use natural methods to nurture the soil and they hand-harvest the buds and flowers before carefully extracting the CBD oil. Our CBD oil is also suitable for vegans and is lactose free and non-GMO.

Are you regulated?

The Cannabis Trade Association (CTA) in the UK works in conjunction with the Home Office. The CTA publish guidelines relating to CBD products and we adhere to these guidelines. We would also like to see a regulatory governing body in the UK, which would govern the industry and ensures standard are met.

Why do you sell different bottle sizes, types and strengths?

We like to satisfy as many people’s needs as possible. Some people want 10ml bottles while others want different sizes. Some people want spray bottles and others want dropper pipettes. The key thing to remember is that the size and type of the bottle is less important than the total weight of the CBD inside. A 30ml bottle containing 500mg of CBD (0.5mg CBD per drop) will be less strong per drop than a 10ml bottle containing 300mg of CBD (1mg CBD per drop) for example. You can buy CBD oil from our shop here.

How quickly do you post out orders?

We aim to ship within 24 hours of receiving the order. We do not work on weekends (everyone needs a break sometimes!) so if you order on Friday we will ship your order the following Monday.

We send our orders via First Class Royal Mail and according to the Post Office 95% of First Class parcels are received within 24 hours of posting. If your order has not arrived please wait up to a week before contacting us, as sometimes the Royal Mail can take a few extra days to deliver. You can buy CBD oil from our shop here.

Can you send products outside of the UK to EU countries?

Yes we do ship our products to the EU. We charge £2.99 for shipping to the EU and it normally takes between 3 -6 working days for orders to arrive. You can buy CBD oil from our shop here.

Understanding The Science & Law Behind CBD

How is CBD extracted from Hemp?

Various methods can be used to extract the CBD oil from the hemp plant, including pure alcohol or butane extraction. We only use CO2 extraction as it is safer, more environmentally sustainable and produces a purer, cleaner oil. Whole-plant CBD oil is extracted using very high pressure (supercritical) CO2 extraction whereas gold CBD oil is extracted using lower pressure (subcritical) CO2 extraction.

The raw cannabinoid extract from the hemp plant is gently heated to around 80 degrees Celsius in order to decarboxylate (activate) the CBD oil. This heating does not harm the cannabinoids in the extract but converts them into more potent chemicals and increase the effects of the CBD oil. We specify the extraction method for each product that we sell.

Why should I buy full spectrum CBD Oil rather than cheaper isolate CBD?

CBD oil is sold as either full-spectrum oil or as a chemical isolate that is made in laboratories, often called 100% or pure CBD. Some of the CBD oils on the market today are made from CBD isolate crystals with many valuable cannabinoids and terpenes missing.

Several studies have shown that the efficacy of CBD oil improves dramatically when a range of cannabinoids and terpenes are available. Working together, this full-spectrum of cannabinoids creates what is known as the ‘entourage effect‘. As Dr. Ethan Russo states,
“Many of these ‘minor’ cannabinoids are seemingly inactive on their own but together they make this beautiful music”.

For this reason, we wholeheartedly recommend that you take full-spectrum CBD oil, as this oil includes a full range of over 100 healthy cannabinoids, of which CBD (cannabidiol) is only one.

What is the difference between whole-plant CBD and Gold CBD?

Our Bristol CBD oils are extracted from organic hemp using supercritical or subcritical CO2 extraction. Supercritical CO2 extraction uses high pressure CO2 to extract all of the plant materials including the cannabinoids, terpenes and dark plant waxes from the hemp. This extract is called whole-plant extract.

Subcritical CO2 extraction uses lower pressure CO2 to extract all of the cannabinoids and terpenes from the hemp but not the heavier plant materials including the dark, bitter-tasting plant waxes which are left behind. The resulting full spectrum CBD oil is a golden colour without the bitter taste. As subcritical CO2 extraction is a less efficient process than supercritical CO2 extraction, gold oil tends to be more expensive than its whole-plant equivalent.

Is Indica CBD oil better than Sativa CBD oil. Do you sell it?

The simple answer is No.

People are sometimes told that they should take CBD from ‘indica’ plants instead of ‘sativa’ plants. However we believe the important thing is finding a whole-plant extract with a variety of cannabinoids that contains the appropriate level of CBD for your needs.

Some companies charge high prices for ‘Indica CBD’ but this is of questionable benefit.

Is CBD illegal?

No. CBD is legal across the EU and many other countries around the world. In the UK it can be sold legally as a food supplement. It is always wise to buy from a reputable company that can provide lab reports. Equally, it is also advisable to check reviews and testimonials about the CBD supplier to ensure that they are providing a high quality product.

If you plan to travel with CBD products, please check the legal status regarding CBD in the country you will visiting, as it is still illegal in many places.

Is CBD Oil different from Cannabis Oil?

Yes. CBD oil comes from the hemp (cannabis sativa) plant, which contains only trace amounts of THC, whereas cannabis oil comes from high-THC cannabis plants.

The only real difference between these two plants is that the hemp plant contains less than 0.2% THC (Tetrahydrocannabinol), the psychoactive compound in cannabis, and so cannot get you ‘high’, whereas the cannabis plant that is used for cannabis oil contains much higher levels of THC and is therefore psychoactive. Apart from this definition, the two plants are virtually identical.

As cannabis oil contains higher levels of THC (more than 0.2%), it is currently illegal in the UK. Some people appear to benefit from taking oil with the higher levels of THC (certain types of epilepsy for example) but this should only be taken if prescribed by a physician. The UK government began to prescribe cannabis oil to patients with extreme conditions in October 2018.

What is THC?

THC, or tetrahydrocannabinol, is the chemical responsible for most of the psychological effects of cannabis.

It acts much like the cannabinoid chemicals made naturally by the body. Cannabinoid receptors are concentrated in certain areas of the brain associated with thinking, memory, pleasure, coordination and time perception. THC attaches to these receptors and activates them and affects a person’s memory, pleasure, movements, thinking, concentration, coordination, and sensory and time perception.

CBD oil does not contain THC levels greater than 0.2% so using CBD oil does not have a psychological effect.

Will I get high from taking CBD?

CBD oil contains THC levels lower than 0.2% so using CBD oil does not have a psychological effect.

What are carrier oils?

Whole plant CBD oil is a very sticky liquid that can be tricky to handle so it is normally suspended in a carrier oil such as olive oil or hemp seed oil. Do not confuse hemp seed oil with CBD oil. For example, our 10ml bottle of 300mg CBD contains 1,500mg (1.5ml) of whole-plant cannabinoid extract suspended in 8,500mg (8.5ml) of hemp seed oil (carrier oil).

What does Third-Party testing mean?

Some CBD suppliers do their own laboratory testing in house, which means they produce the CBD extract and then test it. This can cause a conflict of interest as it is obviously beneficial for the CBD supplier to claim that their CBD oil is strong. The use of a third party laboratory, i.e. one that is not owned or controlled by the CBD supplier, means that the lab report can be trusted.

What are the biphasic properties of CBD?

A biphasic drug is one that has different effects on the body at different blood concentration levels.

One of the most well known biphasic drugs is alcohol. It acts as a stimulant until blood alcohol levels reach 0.05 percent. After this point, continued consumption of alcohol causes sedation and depression.

When CBD interacts with the endocannabinoid system at a low concentration, it has been shown to increase wakefulness, alertness and other elevating responses.

At higher levels of concentration, however, CBD has a sedating effect. For example, people who consume more substantial amounts of CBD may feel sleepy and calm instead of alert and energetic.

Am I allowed to take CBD Oil through an airport?

CBD oil is completely legal in the EU so travel through EU airports within the EU with CBD oil is fine. Outside of the EU different laws may apply and we advise people to check online to find out the rules regarding CBD oil in their planned destination.
