CBD oil is something that has been gaining popularity over the last few years. CBD is one of the compounds found in marijuana, and it has a lot of medicinal properties. Unlike THC, which is the part of cannabis that contributes to people getting high, CBD is not psychoactive. In 2009, there were a number of high-CBD strains of cannabis discovered in California. These discoveries led to the exploration of CBD-based therapeutics, and over the last few years, more and more people have started taking CBD oil, or using CBD based food products, as a way of fighting inflammation and seizures, and treating anxiety and numerous other issues.


CBD and THC work well together and it is thought that the presence of one helps to improve the performance of the other.

So, for example, taking THC and CBD together will reduce the high of the THC while increasing its curative properties, and will also help the CBD to work more effectively as well.

CBD reduces the side effects (anxiety, rapid heartbeat, etc) of THC, and will make THC produce a longer, relaxing but not intoxicating high.

THC, on the other hand, will make CBD’s curative properties stronger.

How to take CBD?

There are several ways that you can take CBD. It is possible to purchase high CBD cannabis strains from a medical dispensary and then smoke or vape them, although this will only be an option in areas where medical marijuana use is accepted. CBD-rich cannabis remedies are sold in a number of forms, but federal law classes them as being illegal just like THC-rich strains.

CBD oil is a slightly more blurry area since CBD oil can be derived from hemp, which is rather different to cannabis because it is bred to not contain THC. This means that there are more places that sell CBD oil, although the legality can still vary from country to country.

  • You can take CBD oil by either adding it to edibles (or eating things like pre-made edible CBD candies and gummy sweets) or by dropping the oil under your tongue and holding it there for several seconds. CBD oil has a strong taste to it that some people find unpleasant, so edibles are popular. Concentrated oils are good to take orally if you can stomach the taste, and vaping is another option.
  • Vaping will offer relief very quickly, but the effects tend to pass after a couple of hours.
  • Orally-administrated CBD oil will take longer to take effect, but the benefits persist for much longer.

If you plan on vaping, avoid oils that contain propylene glycol, polyethene glycol, and any cream or cinnamon flavouring, because all of these things can be dangerous when heated and inhaled.

Dosage of CBD

The effective dosage of CBD varies from person to person. In general, it is best for someone who is new to the world of marijuana to start with a high CBD, low THC oil and begin with a small dose of just a few milligrams. Take a dose a few times per day, every day, for several days, and see how it makes you feel. Increase or decrease the dose depending on how you are feeling. CBD is non-toxic, and there have been no known cases of people overdosing even when taking very large doses, but a large dose is not going to be any more effective than a small dose and could be a huge waste of money. THC can amplify anxiety and cause issues with your mood if taken in high doses, so it is worth being careful.

Choosing a CBD brand

CBD is not regulated, and this means that there are a lot of different CBD brands out there and not all are created equal. (See our CBD brands review page for more info). Look for a CBD brand that shows the ratio of CBD and THC, and that has clear batch labelling, including a manufacturing date. Look for plant-derived CBD without excessive additives, preservatives or thinning agents. Good CBD oil should have been lab-tested to ensure that it is safe (free from solvent residue, bacteria and mould), and pure (meaning no other contaminants). COD or ethanol-extracted CBD is a good choice. Avoid CBD that was extracted using solvents such as BHO, propane, hydrocarbons or hexane.

There is such a thing as single-molecule CBD, which has actually been approved for medicinal use, but it is thought to actually be less-effective than CBD from a plant. It requires higher doses and has a more narrow therapeutic window. Single-molecule CBD is made in a lab, and while it has a similar effect to CBD, it lacks a number of the other cannabinoids that augment the effect of CBD.

Hemp vs cannabis

CBD that is made from marijuana is sold in states where medical marijuana is legal. CBD in England is legal. CBD made from hemp is often used as a loophole to get CBD on the market in areas where cannabis is more tightly controlled. In general, cannabis-derived CBD is more concentrated than hemp-derived CBD, and also is more likely to be pure because so much hemp is required to extract a small amount of CBD there is a greater risk of contamination, and the whole process is less efficient. Growers are working to make cannabis varieties with a THC content below 0.3%, which is the legal limit for hemp. When this happens it will be easier to get good CBD oil all over the world.
