They say it might be the cause of smoking, or drinking !

Blood is described as dark red (venous) or bright red (arterial). The blood you see when you get hurt is usually venous blood. Arterial blood comes out in spurts. As for what causes your blood to be thick or thin-there are actually many reasons things like(anemia, diseases, malaria,etc)
too many to mention here, but I hope this helped you somewhat

I believe sometimes if a persons blood is very dark, there may be a lack of oxygen in it. I am not 100% sure but that is what is coming to mind. As for being very thick, I am not really sure. Naturally, your blood is not red, it is blue but only turns red when it hits the oxygen outside your body. This is something I would definitely check with a doctor about.

The color of your blood varies in color. The more oxygenated it is, the brighter it is. After passing throught the lungs your blood is bright red and ready to distribute oxygen throughout the body. On the blood's return trip it is darker because it is returning to the lungs with waste CO2 to empty through the lungs.

actually, it has nothing to do with smoking and drinking,]
it's oxydation.
The blood is light red it means that blood has been oxydized, it has already went throught your lungs and is carrying oxygen top the rest of your body.
Dark blood means it has just gotten RID of the oxygen.

the blood is red because of oxygen
if the blood is dark, that means that there may be a small amount of oxygen in the body

The color is dark due to the haemoglobin content of the bloood as haemoglobin has iron molecules in it.as per the the physical state of iron we know that in its ferric state its color is dark brown.

Deoxygenated (venous) blood is typically very dark. This is normal.

I'd go see a doctor. They might put you on blood thinners.
