CBD Cannabis and voluntary blood donations: what is the rule?

CBD Cannabis and voluntary blood donations

CBD AND BLOOD DONATION? HERE’S WHAT HAPPENS IF YOU CONSUME LEGAL CANNABIS AND YOU WANT TO DONATE BLOOD.

Blood donations are essential for people who, due to a particular disease or emergency, are in extreme need of transfusions. You know this well, and that is why you would like to go and donate blood at a blood-collect centre, but taking CBD cannabis stops you from doing so.

In fact, concerning the use of marijuana with high THC content the decree-law on blood donations speaks clearly: it is necessary to temporarily suspend such donations so that the concentrations of tetrahydrocannabinol in the blood are entirely disposed of.

So, if you have asked yourself “Can you donate blood after smoking a joint?”, the answer is no! You have to wait at least two weeks, and a doctor will tell you after the pre-donation tests whether you can donate or not.

Marijuana intake and blood donation.

The protocol that regulates blood donations in Switzerland provides for their temporary suspension in particular situations. Such eventualities are many! Among them, we find, for example, the flu, pregnancy, the use of specific drugs and occasional exposure to cannabinoids.

Specifically, the use of cannabinoids involves a temporary suspension of blood donations for at least 14 days (even if it is a doctor who gives his final opinion about the possibility to donate). Of course, people taking “heavy” drugs are entirely excluded from donations.

As you probably know, there are hundreds of active ingredients in marijuana. However, there are two that interact mainly with our endocannabinoid system: THC (tetrahydrocannabinol) and CBD (cannabidiol).

Marijuana intake and blood donation

THC is a psychotropic cannabinoid. Therefore, it alters our perception of reality and our senses. CBD, on the other hand, does not have psychoactive effects but acts mainly on the body with anti-inflammatory, pain-relieving, anticonvulsant and many others.

We want to specify that the amounts of THC present in CBD marijuana are derisory, as they do not reach 2%, while the CBD percentages are usually high.

We also specify that the blood donation law decree considers light drugs (i.e. marijuana) high in THC, but for the moment, it does not speak about CBD weed. However, soft drugs and blood donation are incompatible.

Why can’t people who take marijuana (temporarily) give blood?

The reason is simple: cannabinoids are substances that influence metabolism and blood flow, and with transfusions, they can come into contact with the blood of the recipient. It is not the case that a person who undergoes transfusions – and who can present the most diverse problems – receives blood contaminated with cannabinoids.

Although CBD is not a psychotropic substance, it increases blood flow and influences the metabolism similarly to THC. Therefore, even users of  CBD Buds should avoid donating blood for at least two weeks after taking it.

THC and CBD affect metabolism and blood

As far as the intake of medical cannabis is concerned, the discourse is slightly different. In fact, in Switzerland, it is not possible to use medical marijuana in the form of CBD Flowers. These are sent already shredded to laboratories and pharmacies, which make galenic drugs with precise THC and CBD concentrations.

Cannabinoid concentrations in marijuana drugs are usually low. But there is a problem: it is the diseases for which these drugs are taken that could lead to the inability to donate blood. It is the doctor who selects Avis to decide whether the person taking marijuana for medical purposes can proceed with the donation.

How the THC and CBD cannabinoids affect our metabolism and blood circulation.

It is scientifically known that THC and CBD interact significantly with the CB1 and CB2 receptors of the Endocannabinoid System in our body. CB1 receptors are involved in metabolism and are present in the central nervous system, while CB2 receptors are related to bone metabolism and the immune system.

As you can imagine, these receptors are involved in many processes, including the regulation of perceived pain, liver function, the functioning of the cardiovascular system and the metabolism regulation.

If THC and CBD interact with CB1 and CB2, it follows that they can dramatically improve our metabolism and allow us to manage energy savings better. Therefore, they are very good at preventing metabolic problems and obesity.

Furthermore, the activation of CB2 can lower the risk of atherosclerosis as it reduces the accumulation of plaque in the arteries. At the same time, however, CB1 activation may increase this risk.

Both the change in metabolism and the cardiovascular risk is undoubtedly not appropriate situations for people undergoing transfusion, whether it is a regular or emergency transfusion.

Therefore, if you consume CBD bud or marijuana high in THC, you should avoid giving blood for at least 14 days after taking it. The medical examiner may also prohibit you from donating blood if you use cannabis regularly.
