The Dr. Ed CBD Guide (2023 Updated)

An Introduction to Cannabidiol (CBD)

‘’Cannabidiol (CBD) is currently taking the western world by storm and with good reason. There is a wealth of in vitro and pre-clinical data demonstrating the potential beneficial effects CBD can have in the treatment of a wide range of disorders from anxiety and general inflammation to chronic pain and arthritis. The first ever CBD based medicine has also just been approved for the treatment of severe epilepsy by the FDA. The future is very bright for CBD.

While CBD is certainly a potential boon for health, it is not a miracle cure for everything, so don’t believe those who say it is; and in a growing, self-regulated industry there are a lot of people trying to take advantage. I started this company for discerning customers; customers who put their health first and who are interested in WHY things might work for them. We create our products based on the most up-to-date, peer-reviewed science and craft CBD-infused products of unparalleled consistency and purity in our pharmaceutical-grade lab.

I have a written a starter guide below to introduce you to the world of CBD and how to get started. I hope you find this guide useful and if you need anything else, not matter how small, please feel free to reach out to us‘’

  1. Choosing Your Provider

We hope that by reading this guide, you have chosen Dr Ed® as your CBD provider, but even if not, always do your research. This is about your health and lots of people will try and take advantage of that. Based on our investigations, around 70% of the CBD ‘producers’ in the UK are what we refer to as ‘bedroom blenders’.

There are a mixture of small companies and individuals that mix low quality and inconsistent ingredients together to make their products. Not all are doing this to make a quick profit, some sell to friends and family for example. The point is, only a handful of CBD brands have the authority, expertise and facilities to produce high-quality, lab grade, reliable CBD products.

This is not intended to scare, but rather, highlight that research is important and that you can’t trust everything you read on the internet!



Evidence-based medicine is at the core of human health and why our average lifespans have doubled over the last few centuries. We use techniques and medicines that have been thoroughly investigated and tested for effect. CBD may be only now growing in popularity but the EVIDENCE that it works is incredibly important. The Dr Ed Blog section which you can find on our website, is an attempt to educate and collect the most important evidence for the effects of CBD on human health in one place.


Here you will find in vitro, pre-clinical and clinical data focused on CBD therapies and their efficacy in treating specific ailments, written in a digestible way. We create our products based on the findings of top-rated peer-reviewed research not anecdotal stories and fads. CBD blogs and hundreds of websites CHERRY pick the data, often taking very poor-quality research or testimonials and making wild health claims off the back of it. If a brand or company does this be very wary of their intentions. CBD has lots of potentially very powerful health effects, but it is not a miracle cure.


 Credentials and Expertise

One of the key things to look for are the credentials behind the supplier. Are they scientists, are they doctors, are they CBD experts – do they have a deep understanding of human health or topics relevant to CBD-derived products? If suppliers and brands do have this sort of authority and experience, they will make it clear to their customers. If they don't, they’ll remain quiet on this front and offer up only sparse science and evidence regarding the effects of their products.  This isn’t to say that you should blindly trust those with fancy letters before or after their names, but, that years of dedicated study and research makes a very big difference when it comes to product development and product recommendations.


Questions to consider:

  • Does your supplier discuss, highlight and understand the science behind their product?


  • Does their team include people with relevant experience in science or health?


  • Does your supplier have clear and concise branding and labelling?


  • Does you supplier have a dedicated production facility?


  • Does you supplier have good user reviews and recommendations?


 Lab Reports

In a largely self-regulated industry like this one, lab reports are fairly rare to come by but are incredibly important. Any brand can put a label on the side of a bottle but only a handful have the resources, facilities and commitment to transparency to analyse their products and create detailed lab reports about the contents. 

As a consumer, lab reports should be one of the first things you look for on a supplier’s website; they may have links or they may display them directly. Lab reports show they take the industry seriously, but more importantly they take you seriously as a discerning customer. A detailed lab report will break down all the ingredients in a CBD product as well as the exact amount of that product. As the ‘oil’ in CBD oil can be a variety of oils and solutions, lab reports allow you to get down to the nitty gritty to see if a product is right for you.

Lab reports aren’t just great for consumers but for suppliers as well. Creating products with consistent levels of CBD allows brands and suppliers to build a reputation as a reliable brand. As CBD is very personal, finding the right dosing for you can take time – it is therefore critical that if you find a dose and product that works for you, the next bottle you order is exactly the same. Consistency is key and without lab analysis it is hard to do that.



  1. Choosing Your Dosage

Finding out the right dosing for you encompasses more than working out what your body responds to best. It also involves fully understanding the CBD product label. As the CBD industry is fairly new and growing, there is no universally agreed way to label CBD-derived products, so checking the labels is always a must.


 Understanding the product

When it comes to your health, time spent double checking labelling is time well spent. The first step is to understand exactly what it in your product. Check the quality of the labelling and the list of ingredients. Take a close look at the CBD content and how this is displayed., Sometimes the amount of CBD stated is the quantity of CBD hemp concentrate used to make the product, not the actual amount in the bottle.


For this reason, it is wise to trust a choose a brand which has clear and consistent labelling and displays the actual amount of CBD in the product.


This is important not just from a cost perspective but from a dosing perspective as you can accurately record and measure how much CBD you are taking.


As poorly labelled products can contain variable levels of CBD depending on their level of refinement, your 5% oil could actually contain very low levels of CBD which equates to less than 1% actual CBD. In other words, not what you paid for!


Percentage vs milligrams

As there are no standardised labelling methods, CBD products are often labelled with the quantity of CBD as either percentage (%) or milligrams (mg). Unusually, if a product is labelled with milligrams, this refers to the amount of CBD in the entire product not per millilitre.


For example, a 1000mg CBD oil bottle which is 10ml contains 100mg of CBD per 1 ml (1000mg/10mln = 100mg per ml), whereas a 1000mg CBD oil bottle which is 30 ml contains 33.3mg of CBD per 1 ml. In other words, despite practically identical labelling, the larger bottle of CBD is 3 times weaker than the small bottle.


Percentage (%) is a much more accessible way of labelling CBD content as 5% CBD means 5% of your product is CBD regardless of the total size of the bottle or container.



Start slowly

Taking CBD is an individual experience, with dosing and frequency varying widely. As such it is not appropriate for us to tell you how much CBD to take. However, we do suggest you start slowly, to find out what works for you.


There are currently no official guidelines around how much CBD to take and there is currently a lack of solid clinical evidence to definitively state the therapeutic range of CBD. Research effort is currently underway to address this. As of early 2020, the FSA has recommended that no one exceed 70mg a day of CBD. Additionally, pregnant and breastfeeding women as well as individuals on any other medications are advised to avoid CBD products altogether.


Using CBD should be approached with a holistic mind. As CBD is a biologically active compound, things like body weight and age should be taken into consideration. Things which are harder to determine but which may also affect dosing efficacy include metabolic rate, genetics and the current health of your endocannabinoid system.


The best way to start is slowly, with a low dose. Keep a close eye on your mood, attention and how your body feels. Gradually increase your dosing and see how your body reacts until you reach a level that you feel is beneficial. Many find that keeping a quick ‘dosing diary’ every day is a very effective way of quickly establishing the sort of dosing that is right for you.



  1. Taking CBD


There are a large number of ways to take CBD, which means the benefits of CBD are within everyone’s reach. We’ve summarised the most common ways below and each have their own particular strengths. Some people stick to one route and others mix and match; it is entirely up to you.  


4.1 Tinctures

Dr. Ed CBD Tincture Bottles 

A tincture is the classic oil dropper type of application and the most common way to currently purchase and use CBD. Use the pipette to drop CBD under the tongue and hold under the tongue for around 60 seconds before swallowing.


This is known as ‘sublingual’ application. Due to the large number of capillaries and good blood flow under the tongue, sublingual application is one of the fastest and most effective ways to take CBD. As CBD has direct access to the blood stream, it bypasses first stage metabolism by the liver, increasing the amount of CBD present in the blood system.


Calculating amount per drop:


Most oils come with a 1 ml dropper. Assuming a 10ml bottle with 1000mg, each 1ml dropper will contain 100mg of CBD.


1000mg/10ml = 100mg per ml.


If you have decided to start at 25mg, then simply fill the dropper a quarter full. This method isn’t 100% accurate but serves as a solid estimate of your dosing. A more detailed dosing guide for droppers can be found on the relevant product pages of our website.


4.2 Sprays


Sprays are starting to gain popularity and are also considered a sublingual route of administration as the CBD is sprayed under the tongue. Sprays are more discrete and easier to use than tinctures hence their growing availability.


Most suppliers will also state the amount of product released per push of the spray so you can quickly workout how much CBD you are taking. However, container quality matters here as some poorly made sprays are prone to leaking or breaking – choose your spray carefully based on specific product reviews.



4.3 Vape


As can probably be guessed, CBD is now available in e-liquid form so can be vaped. The lungs have a massive blood supply, so vaping is an efficient and fast way to consume CBD. As above, note the milligram amount of CBD per ml of your e-liquid. By doing this you can work out how much CBD you place in the tank of your vape device and can keep track of it through the day.


If you want to be taking 100mg per day and you are using a 500mg bottle of e-liquid, 2mls of your e-liquid will provide what you need. So, if you finish that 2ml tank in the day you will have correctly dosed with 100mg.



4.4 Edibles


Edible CBD usually comes in pill or capsule form which can be hard, soft or liquid (similar to a fish oil pill). The ingested CBD is absorbed primarily in the intestinal tract which has numerous blood vessels. Eating CBD leads to the slowest rate of absorption and a number of other factors can influence this including the type of food you’ve eaten.


CBD capsules are one of the easiest ways to correctly dose as each capsule has a specific amount of CBD. It doesn’t get easier than taking a capsule.


Other ways to eat CBD include things like gummy sweets as well as drinks.


4.5 Topicals


CBD can be absorbed through the skin so topical CBD products like balms, creams and lotions can all provide benefits and can generally be applied in the same way as any other non-CBD products you have. Topical CBD is typically used for muscle aches, sprains and minor injuries and applied directly to the site.


To work out roughly how much CBD you are taking, simply divide the CBD weight in mg by the volume of the product. While not all of the cream/balm/lotion will be absorbed, this is certainly a better method than not measuring at all.


  1. The Science of CBD


5.1 Cannabidiol (CBD)


CBD is a phytocannabinoid, one of more than 100 cannabinoids currently identified. Along with tetrahydrocannabinol (THC), CBD is one of the major cannabinoids found in cannabis and it’s derivatives like hemp. CBD is psychoactive as it does alter signalling in the brain as well as mood regulation, but it is not psychotropic or ‘high’ inducing like THC. Current studies suggest CBD is a well-tolerated, non-toxic and safe compound with a range of very attractive potential therapeutic properties which are currently being investigated. CBD exerts its major effects through components of the endocannabinoid system or ECS, a highly conserved biological system which all humans and almost all animals possess.



5.2 The Endocannabinoid System (ECS)


The endocannabinoid system is a signalling system with multiple parts, many of which are likely unknown as of writing. Based on current evidence, the ECS is present in all animals and is affected by diet, sleep, stress and a host of other factors including exposure to our own natural endocannabinoids and phytocannabinoids like cannabidiol (CBD). Understanding how the ECS works and how we can modify its activity may offer tremendous therapeutic potential in the treatment of a wide range of health disorders ranging from mental health issues to pain, nerve damage, metabolic diseases like diabetes and brain disorders like Parkinson’s Disease.

Although the endocannabinoid system is composed of many different components, the most well established at CB1 and CB2 which are considered the primary receptors of the system through which endocannabinoids and compounds like CBD produce their effects.


Humans produce their own natural endocannabinoid molecules which interact with the ECS to regulate a vast array of biological processes including aspects of the immune system like pain and inflammation, reproduction, food intake and reward and modulation of the HPA axis. Modulating the activity of this system may offer tremendous therapeutic promise for a diverse scope of diseases, ranging from mental health disorders, neurological and movement disorders, pain, autoimmune disease, spinal cord injury, cancer, cardiometabolic disease, stroke, TBI, osteoporosis, and others. CBD and other cannabis derivates are not miracle cures or cure-all remedies. Instead they are interesting compounds with diverse therapeutic values.
