CBD Oil Guide

Our CBD guide is here to help you buy CBD with confidence. Here at Mercury CBD we understand that information available online can be conflicting, confusing, vague and often factually incorrect. Here in the UK you can buy CBD products legally and there are many different ways in which to consume CBD.


So what is CBD? 

CBD or cannabidiol is one of the most well-known cannabinoids naturally occurring in the cannabis plant. Cannabidiol is non-intoxicating, unlike its more notorious counterpart, THC (tetrahydrocannabinol). Taken responsibly, CBD is a safe food supplement that can be used as part of a healthy, balanced diet.

If you’re looking for the best quality CBD in our opinion these are the things to consider:


Clear CBD content

Percentages can be confusing because the strength of the product also depends on its volume. Unlike nicotine products, CBD products just show the total amount of CBD in the product, irrelevant of bottle size. Nicotine products show the amount of nicotine per ml.

So for example a 10ml bottle of e-liquid with 6mg of nicotine would be the same strength as a 50ml bottle of e-liquid with 6mg of nicotine as this is scales with the bottle size. Whereas a 10ml bottle of CBD e-liquid with 500mg of CBD would be 5x more concentrated than a 50ml bottle of CBD e-liquid with 50mg of CBD in.

Everyone reacts differently and there isn’t a standard amount of CBD everyone should take. Knowing the exact amount in milligrams per millilitre (eg, 1000mg in 10ml) means you can measure and monitor how much you’re taking to work out what concentration of CBD is right for you.


A safe THC content

Does the product’s certificate of authenticity prove that the THC content is within the legal allowable range? This is very important as it ensures you’re buying a legitimate product that adheres to UK law. We also use THC free oil to eliminate the chances of failing any drug tests.


Check the testing of the products

Do not let yourself be deceived by empty marketing claims or inferior products like CBD drops made from crystal isolates or from undisclosed sources. (CBD isolates or crystal isolates are a concentrated, lab-produced form of CBD, with no other cannabinoids present.) If a brand or retailer is not willing to show the source and what exactly is in their products via third-party lab tests, question why this is and move on to the next brand. Certificates of authenticity need to be made available upon request.


What is the best method to take CBD

Inhalation happens to be the most effective and fastest method because the CBD goes into the bloodstream through your lungs. There is a greater bioavailability of CBD as it is not broken down in the digestive system like oral drops. We recommend the Aspire Pockex Vape pen to vape your CBD. This is ideal as it works at around 18 Watts (CBD ideally should be vaped at between 10 – 50 Watts). The Aspire Pockex is also easy to use and at an affordable price.


How long do the effects of CBD last?



Vaping CBD oil is generally the quickest way to feel the benefits of CBD with the effects of CBD taking effect also immediately. The effects are expected to last around 2 – 3 hours.


Tinctures (oral drops)

CBD tinctures are most effectively taken by mouth, with most people holding the CBD under their tongue for 1-2 minutes and then swallowing. It typically takes 15-30 minutes to feel the effects of CBD through this method of consumption, with the effects being known to last between 4-6 hours.


What is the difference between CBD and hemp oil?

CBD oil is an extract made from the full cannabis plant (including leaves, flowers, stalks and seeds), whereas hemp oil is pressed from industrial hemp seeds only. If people are advertising hemp oil as CBD oil then it is a scam. The key differences are:

  • CBD oils are rich in cannabinoids (CBD, CBG, etc.) and are sold as food supplements in the form of extracts, e-liquids, gummies and balms.

  • Hemp oil is an Omega-rich cooking oil, normally eaten raw (unheated) as a salad dressing. It contains negligible amounts of cannabinoids. Hemp oil is very versatile and is also used as a natural moisturiser in skincare products and for the creation of bio-plastics, paints and fuels.
