I have a medical coming up but this time they want blood not urine! How long does it take for skunk and valium to clear from the blood?

Quantites mean everything...

Without knowing them... its difficult for anyone to even guess.

The valium will take the longest. It has a half life up to 100hrs, or four days. Which means it will take 20days for 5mg to degrade to .3mg. Three weeks. The canabis will be out of the blood stream much quicker.

So, if you're having a blood drug screen, why are you doing drugs? What happens when you fail?
