What Is Blood Plasma?

Blood Plasma is the yellowish liquid part of the blood. It comprises salt, water, antibodies, and proteins. The primary function of blood plasma is to regulate healthy blood volume in the body. It also plays a vital role in supporting the immune system since it is packed with antibodies. It also distributes nutrients and hormones throughout the body.

The procedure for drawing blood plasma is pretty quick and straightforward. A high-technology machine is connected to the arm of the donor. The device collects blood, separates the plasma, and returns the rest of the blood and its components to the arm. Normal Saline is also injected into the body through this apparatus. 

After the collection, the donation centers freeze the plasma to preserve its components. This way, you can preserve frozen plasma for up to a year. The plasma is thawed and used per the patient’s need whenever needed.

Precaution for Cannabis Users

The information mentioned above establishes that it is safe for cannabis users to donate plasma. However, there are specific precautionary measures that you must keep in mind before donating plasma. You should refrain from smoking cannabis at least 24 hours before donating the plasma. This will remove leftover active THC from your body. 

In addition to that, it is better if you avoid edible cannabis. The reason is that edibles take much longer to exit your system. Therefore, THC takes more time to leave blood plasma. More importantly, you must not smoke cannabis before you donate plasma. You will immediately be disqualified if you are high. This is because donating plasma in such a state can lower your blood pressure, creating complications.
