Use of medical cannabis throughout history

The cannabis plant has been used for many purposes by humans for many thousands of years. Evidence has been found that cannabis was cultivated 5000 years ago in today’s Romania. Likewise, 10 years ago cannabis was found in the Yanghai Tombs near Turpan in China. Here a shaman was buried with almost a kilo of cannabis 2,700 years ago, and additional studies showed that the cannabis was containing THC. One that the first evidence, which strongly suggests that cannabis has been used for medical purposes, dates back to 200 BC when found residues of THC in ash. In recent times, cannabis has also been used for medical purposes, and even the nobility used cannabis. In the 1890’s, Queen Victoria of England received cannabis by her physician against her menstrual pain. Cannabis has been used since the beginning of civilization and people have long been aware of the plant’s many good qualities and uses. We are fortunately in Denmark now so privileged that we again have the opportunity to use cannabis for medical purposes, and it is our clear belief that it will undoubtedly benefit thousands of people.

Sativa, Indica and Ruderalis

There are three different types of medical cannabis; Sativa, Indica and Ruderalis. Each has the three types of specific characteristics. In Organic Cannabis Care we only cultivate Sativa, Indica and hybrids, and therefore we will focus on the two types. Sativa has long thin leaves and the plant can grow above 2 meters tall. The effect of medical cannabis from the Sativa plant is uplifting and energetic. Indica plants here short thick leaves and have a short and bushy structure. By ingesting medical cannabis from an Indica dominant plant, the patient will feel more relaxed. Hybrids are crossings of Indica and Sativa, where through breeding you try to take specific characteristics of the two types and combine them.

How does cannabis work and what is happening in the body?

When consuming cannabis, dopamine is released via the neurons in the brain. Dopamine is a signal substance that is formed in connection with, for example, exercise, sex and alcohol, and plays a crucial role in brain reward systems. Dopamine gives a sense of happiness and well-being.
But what else happens in the body when you take cannabis?
The endocannabinoid system functions as a communication system between the brain and the body, and it is believed that it helps to distribute the body’s resources to where they are needed. Throughout the body, there are endocannabinoids and their receptors, CB1 and CB2. CB1 receptors are found in the nervous system, connective tissue and in organs, and CB2 receptors are found mainly in the body’s immune system, but also in the organs of the body. Endocannabinoids are cannabinoid molecules that the body itself forms, and these act as signal substances for the CB1 and CB2 receptors.

Research has shown that the endocannabinoid system affects the following functions in the body:

Immune system
… And much more
This is also the reason why cannabis can help many patients with different diagnoses.
William Devane of the National University of Ireland has been researching cannabis for many years. He discovered Anandamide (AEA) in 1992, which is an endocannabinoid we humans themselves form in the body and considered to be the body version of THC. THC is a phytocannabinoid, which means it comes from a plant. Since then, research has shown that AEA has properties that affect mental health, pain relief, appetite, and memory. Not surprisingly, some phytocannabinoids inhibit the degradation of AEA, which gives a greater beneficial effect on the substance. As cannabis has been criminalized for about 60 years, this has made it difficult for researchers to study the many different cannabinoids and their effects on the body. Fortunately, is it easier for researchers to initiate and fund their studies of cannabis today, and new knowledge about this amazing plant is increasingly surfacing. Our hope is that in the future we can specialize the different types of medical cannabis for the individual patient, and this is a dream we are striving to realize in Organic Cannabis Care.


We have been contacted by some patients who have had a lot of questions about medical cannabis. We would like to help and inform the patients who are looking for us, but it is extremely important that you as a patient talk to your doctor about the use of medical cannabis and which method best suits your needs.
Below we have answered the questions we are often asked.


Most used methods

The two most commonly used methods of taking medical cannabis are ingestion by inhalation or by oral ingestion. These two methods have different effects because the active substances in the medical cannabis are absorbed into the body in two different ways.

By inhalation

By inhalation, the active substances in the medical cannabis, mainly THC and CBD, are absorbed into the blood through the lungs. In this way, the active substances are led to the brain after which the effect occurs. From the inhalation of the medical cannabis until the effect occurs, in some cases a soothing effect may be felt in less than one minute. By inhalation, the effect last for 2 to 4 hours.

By oral ingestion

By oral ingestion of food containing medical cannabis, the active substance THC is metabolized by the liver such that the Delta-9-THC molecule is converted to 11-hydroxy-THC that passes through the blood-brain barrier more easily and has a greater effect than normal THC. However, it may take between 1 to 2 hours before the effect occurs. Therefore, as a patient, be more careful when taking cannabis orally and do not dose again until you are sure that the full effect has occurred. For some, it may cause discomfort if the effect becomes too strong because you have been impatient and have taken more than the doctor’s dose. In oral ingestion, the cannabis cannabis may have effect for 6 to 10 hours. Therefore, this method would be perfect for patients with chronic pain to provide them with prolonged relief.

Other questions

How much medical cannabis should I take and how often should I take it?
It is very important that you, in cooperation with your doctor, find the dosage that suits your needs. Like all other medicines, medical cannabis works differently from person to person. This also applies to the effect thereof. Therefore, it is important that first-time users of medical cannabis together with their doctor try out with small doses at the start. If the desired effect is not achieved, talk to your doctor about increasing the doses or frequency.
Can I drive by car when I use medical cannabis?
It is up to your doctor to assess whether you can drive by car when using medical cannabis.
