An Overview of Cannabis

Cannabis with low levels of THC under 0.3% and high levels of CBD is commonly called Hemp or Industrial hemp. Cannabis with higher levels of THC is sometimes called marijuana or weed. Industrial hemp is normally grown for its fibre and cannabis with high THC has been used medicinally or as a recreational drug far back into antiquity.

Cannabis Indica was first observed by Jean-Baptiste Lamarck  in 1785 a french biologist travelling in India who noticed the differences in the plants.

In the 1880’s William Brooke O’Shaughnessy, an Irish doctor introduced the plant medicinally to the west after seeing it used in India and was the first person to publish a method to manufacture medicinal cannabis oil.

Cannabis was listed in the United States Pharmacopeia from 1851 until 1941 until marijuana was outlawed in the USA. The first commercially produced medicinal cannabis oils were sometimes made with 80% Alcohol to make a tincture.

What’s the difference between Medicinal Cannabis Oil with high levels of THC and Medicinal Cannabis Oil with high levels of CBD?


Medicinal cannabis oil can be made from any type of cannabis plant or industrial hemp. Cannabis plants can have varying levels of levels of THC and CBD. Hemp generally has low levels of THC and high levels of CBD.  In the past few years many hybrid strains have emerged that have a 1:1 THC CBD ratio or other variations since getting the right ratio of cannabinoids has proven effective for certain medical conditions.

THC (Tetrahydrocannabinol) is the cannabinoid that gets you high or stoned. CBD (Cannabidiol) is non psychoactive and won’t get you high. THC is also illegal in many countries so unless you live in a place that has legalised marijuana you risk getting in trouble with the authorities for manufacture or possession of high THC medicinal cannabis oil.

In most countries CBD rich medicinal cannabis oil is perfectly legal but we advise that you check first before purchasing or trying to make you own so you fully understand the legal framework and risks in your jurisdiction.

Is Medicinal Cannabis Oil better with more THC or more CBD?

This is a tricky question to answer and one that even within the industry is still hotly debated. People like Rick Simpson, the creator of Rick Simpson oil or RSO and the man behind the documentary “Run from the Cure” is convinced that for treating diseases like cancer it’s the THC that is important. Rick Simpson claimed to have cured his skin cancer by making his own homemade medicinal cannabis oil and has taught others how to make it.

Due to Rick’s documentary there is a lot of misinformation on the web that claims that THC is the only cannabinoid that affects cancer but this is clearly not true and is not upheld by proper scientific research or clinical trials. There are many other Cannabinoids like CBD, and CBDa that may also have anti cancer effects but so far these trials have been on rats or cell cultures in a laboratory not on humans.

High CBD medicinal cannabis oil came to the public attention through the story of Charlotte Figi whose parents treated her rare form of epilepsy, Dravet Syndrome using CBD extracted from strains that were high in CBD and low in THC.

There has not been enough research or medical trials to say for certain which is better and from a legal standpoint as manufacturers of CBD oil we cannot give any medical advice concerning the effectiveness of cannabinoids for treating disease.

Is hemp oil the same as medicinal cannabis oil?

It’s easy to get confused between hemp oil and medicinal cannabis oil, since they are both made from the same plant and also because hemp oil is very beneficial containing a lot of antioxidants and omega 3 and 6 fatty acids.

Hemp oil is normally pressed from the seeds of the hemp plant, which means it does not contain the same amount of cannabinoids found in medicinal cannabis oils which are extracted from the whole plant.

Hemp oil does have trace amounts of CBD,  normally less than 25 parts per million (ppm) compared to medicinal cannabis oil extracts that typically contain between 3% and 30% CBD  (30,000ppm – 300,000 ppm)

Many manufacturers label their CBD products as hemp oil, and a lot of CBD Oil uses hemp oil as the carrier base oil which is what creates some of the confusion.

What’s important is the mg(milligrams) of CBD that you are buying. If it doesn’t say it on the label then assume that what you are buying is just plain old hemp oil and not medicinal cannabis oil.

What are the side effects from taking Medicinal Cannabis oil?

There have been no documented deaths from taking medicinal cannabis oil. Although it is generally agreed that high THC cannabis oil may have a strong psychoactive effect that is different from person to person depending on your experience and tolerance. The effects will vary depending on the strain and the particular THC to CBD ratio. Some types of cannabis oils have a very euphoric effect while others are more sedative and relaxing.

The side effects can be both positive and negative. Generally all cannabis oil gives you a sense of relaxation and wellbeing, some people get the giggles while others get the munchies (appetite stimulation). On the negative side you might experience slight dizziness or nausea and a few might experience paranoia, panic attacks or hallucinations. Most effects wear off completely within 24 hours and even if you do overdose you will normally just fall asleep.

CBD tends to reduce the psychoactive effects of THC which is why many manufacturers are experimenting with different THC : CBD ratios in their products.

Is Medicinal Cannabis Oil Legal?
