Medical marijuana

News and developments on the medicinal properties of marijuana

For thousands of years, marijuana has been used worldwide as a medicinal plant, taking advantage of the numerous therapeutic properties of cannabinoids (THC, CBD …) together with aromatic molecules (terpenes) found in cannabis.
Here, we present several articles on the therapeutic use of marijuana, as well as a monthly or bi-monthly compilation of news related to the world of medical cannabis, highlighting advances and scientific studies conducted internationally.

Cannabis and endometriosis

The use of medical cannabis to treat ailments and the symptoms of a large number of diseases is becoming increasingly common, as are the many users who testify to its effectiveness compared to the so-called “synthetic drugs”. While sometimes the use pharmaceutical medicines may be essential, we are increasingly more aware of the medicinal properties of cannabinoids and terpenes and how to use them, either to alleviate the symptoms caused by the disease itself, or to mitigate possible adverse effects of medications or treatments.

One condition for which cannabis seems to be of great help is endometriosis, a chronic disease estimated to affect more than 170 million women worldwide, and one that in many cases goes undiagnosed. This past March was the Endometriosis Awareness Month, a global initiative aiming to raise awareness of this problem and encourage governments and organisations to actively fight against this disease.

What is endometriosis?

As we saw in our article on cannabis and menstruation, each month women lose endometrial tissue during their period, the tissue that normally envelops the uterus. Endometriosis is a gynaecological disease in which said tissue (endometrium) also grows in other internal areas of the body such as the ovaries, fallopian tubes or intestines. We can define it as an abnormal growth of the endometrial tissue outside the area where it should grow (the lining of the uterus), and that also is not expelled from the body during menstruation.

Dogs, cats and CBD: Cannabis and pets

As research on the different cannabinoids and terpenes  – and other compounds produced by the cannabis plant – advances, more and more testimonies claim that the efficacy of these substances is beyond doubt. While further research is needed in both humans and animals,  cannabinoids like CBD are being increasingly used to treat diverse symptoms and pains in pets, since many users have realised the great benefits it can provide in some cases.

The endocannabinoid system of animals

Mammals, as our beloved dogs and cats, all have an endocannabinoid system composed of CB-1 and CB-2 receptors, which also produces endocannabinoids. When they detect the presence of other cannabinoids in the body, these receptors react in much the same way as they do in the case of humans, so it is believed that cannabinoids and terpenes could provide similar benefits in animals. While the CB-1 receptor is focused on the activity of the brain and central nervous system (CNS), the CB-2 receptor is mainly found in peripheral organs like the immune system. The most important here is that phytocannabinoids (cannabinoids produced by plants) activate these receptors, providing a number of beneficial effects.

How cannabis can help during your period

A large proportion of women have several symptoms before and during their period, no matter their age, physical condition or medical record. Furthermore, the days before the start of menstruation are sometimes the hardest for most of them, with a group of symptoms commonly called PMS or premenstrual syndrome. For centuries, medical marijuana has been used across the world for its therapeutic potential, and menstrual cramps are not an exception. In this article we’ll focus on how cannabis can help relieve these symptoms, and we’ll tell you everything you need to know if you decide to use marijuana to treat them.

Juanita la Lagrimosa, the origins of CBD

The birth of CBD-rich cannabis strains

Today, one can find a myriad of cannabis genetics with high CBD content on the seed market, with diverse cannabinoid ratios and thus medicinal effects. From 1:1 THC:CBD varieties to those with awesome 1:20 (even higher) ratios, breeders and seed producers have relentlessly bred new CBD strains over the past years. But where do all these new varieties come from?

According to an article published by Soft Secrets, and as our friend Jimi from Reggae Seeds confirms, it all started with the creation of Juanita la Lagrimosa (Reina Madre x NYCD), the flagship strain of this seed company.

In this case, the parent transmitting the CBD trait was a New York City Diesel plant selected by Jimi from a pack of Soma Seeds purchased at 2004 Spannabis. 3 nice males were selected, one of them being particularly outstanding in terms of aroma. Continue reading

The effects of cannabis on sleep

Many users ? both medicinal and recreational ? use cannabis right before going to sleep because of the effects on this important phase of our life. While many of them get a more restful sleep, one of the side effects reported by users is not dreaming or, at least, not remembering any dream. But, why does it happen?

Why do we sleep?

Before understanding what are the effects of cannabis on sleep, we should start with the basics?why do we sleep? The research about sleep is still at a very early stage, in fact until recently it was thought to be a passive state of the body. Today, and with all the information that we can get from brain waves, heart beat and blood pressure, breath frequency, hormone segregation and some other biomarkers, is it believed to be as active as the waking stage.

Sleeping is a regeneration state. In studies of sleep deprivation it has been observed that if we shorten the sleeping hours, then the body will try to catch up on sleep in the next sleeping period. Moreover, if we deprive our sleep of one of its phases, our organism will try to recover this phase in the next sleep. Pushing the limits of sleep deprivation may lead to death. Continue reading

Medicinal properties of CBD

What is CBD?

CBD is a cannabinoid present in cannabis plants with a very similar molecular structure to THC but without any kind of psychoactive effect. Indeed, CBD does not cause any effect on the user, no paranoia, euphoria or intoxication, which are usually associated with THC and the recreational use of marijuana.

Cannabidiol (CBD) has several therapeutical properties that we’ll present in this post. As mentioned, some of the most interesting aspects of this cannabinoid are its low toxicity and few side effects associated with its use: in the worst case, an over-dose of CBD would simply put you to bed. It has been demonstrated that CBD has low affinity with the CB1 and CB2 cannabinoid receptors, but it does act on other receptors of the human body like GPR55 or 5-HT1A.

History of the medicinal use of cannabis

Cannabis or marijuana has been accompanying mankind for more than 10,000 years, which has found the myriad of uses of this plant, either at recreational, medicinal or industrial level. The first evidences of cannabis were found in Asia, so it is not strange that the first written references we have about cannabis come from this area, especially from China and India.

Although the first traces of the use of hemp date back to about ten thousand years before Christ, the first written reference to its medicinal use is found quite later, around the year 2737 BC. Still, it isn’t difficult to imagine that the therapeutic traits of cannabis had been discovered discovered rather earlier.

First medicinal uses of cannabis

As we mentioned about the therapeutic use of hemp, we know that it was already contained in the pharmacopoeia of Shen Nung, Chinese emperor and father of the Chinese medicine, who compiled his knowledge of medicinal plants in a book written in 2737 BC. The legend says that, apart from discovering the medicinal properties of cannabis, Shen Nung also investigated the properties of ginseng and ephedra. The first written reference of the medicinal use of cannabis is also found in the Chinese Pharmacopoeia, the Rh-Ya, in 1500 BC.

From this point, we found a series of cases in which this plant is recognized as an effective remedy for many ailments. The Ebers Papyrus, dated about 1500 BC and written by the Egyptians, mentions the medicinal properties of marijuana, for example, describing how to use it on a suppository to relieve hemorrhoids. In 1450 BC, in the Book of Exodus, a sacred ointment made of Kaneh-Bosem – a word that numerous and reputable specialists have identified as hemp – is mentioned. But, back to Egypt, traces of cannabis pollen have been also found in the tomb of Ramses II, who died in 1213 BC. We also know that Bhang was used in India since the year 1000 BC, a drink made of milk and marijuana used as anesthetic or anti-phlegmatic.

The medicinal use of hemp soon spread westwards, leaving clear evidence of this fact: in the Middle East, the Persian prophet Zoroaster (Zarathustra) wrote the Zend-Avesta in the 7th century BC, a religious text strongly influenced by the Vedas, in which Bhang is mentioned and cannabis is classified as the most important among 10,000 medicinal plants in one of its volumes, the Venidad. The first detailed written work explaining the properties of the hemp in India dates back to 600 BC, the Treatise of Ayurveda medicine in Sushruta Samhita.

Benefits of Cannabis for Alzheimer’s disease

What is Alzheimer?

Alzheimer’s disease is a degenerative pathology that causes progressive and total loss of the cerebral functions in elderly people, especially memory. This disease affects about 30 million people worldwide, a number that will double in the following 20 years due to the aging of the popolation in the industrialized world. Alzheimer affects more women than men, especially because women live longer and this disease development is closely linked with aging.

Today, in Spain, more than 600.000 people suffer from Alzheimer’s disease, with 40.000 new cases every year. Once the disease starts affecting the person, life expectancy greatly depends on patients (from 3 to 20 years), with an average of 8,5 years. Patient associations estimate that we’ll have around 1,5 million people suffering from Alzheimer in Spain by 2050. (Source: Spanish Society of Neurology). Continue reading

Release from the Spanish Observatory of Medicinal Cannabis

Spanish Observatory of Medicinal Cannabis

Spanish Observatory of Medicinal Cannabis

On the occasion of the sad news published yesterday in France, in which cannabis was falsely indicated as cause of one death and five severe cases among the patients of a clinical trial, the Spanish Observatory of Medicinal Cannabis states:

  1. The French Ministry Health of France has officially confirmed  that the drug used in this trial does not contain any cannabinoid, neither natural nor synthetic. Therefore, users of medicinal cannabis can be completely confident.
  2. The wrong mention of cannabis in the news published has generated a situation of alarm completely unnecessary and unfair.  For this reason, we stress the need for truthful, accurate and scientific information on cannabis and its therapeutic purposes.
  3. Bial laboratories (responsible for the drug used in this trial) informed that this drug is an inhibitor compound of the FAAH protein (fatty acid amide hydrolase). Continue reading
