Can A Routine Blood Test Detect Marijuana In Your System?
I am going for a normal blood test to decide if I am able to take a pill, and was wondering if they can detect marijuana in your system during the process? Or would they have to look for it specifically to find it? Thanks!!



its called a toxicology test, and it’s very specific.

The only way it will show up is if they run a drug screen. Usually for a normal CBC (blood test) it will not be tested. The only way to know for sure is to know exactly what “blood test” was ordered. There are many different tests that can be run on your blood.

aaa unless they’re actually looking for it then yes but since its just a routine blood test then no it won’t show up on the results

You could be high as a kite WHILE they are drawing your blood and they won’t see the marijuana in your system unless they look for it.
A normal “blood test” doesn’t look for those things.
