But it's kind of interesting because blood testing for drug use is incredibly, incredibly accurate. It's very good for finding stuff. But unfortunately, the amount of time it's detectable in your blood, the window is very short. So for instance, amphetamines aren't detectable after like 10 hours in your blood. That's good to know. Methamphetamine is about 24 hours. Barbituates, possibly about a day or two. Benzos could be as quick as six hours later out of your blood. Cocaine, generally about 12 hours. It's not detectable in your blood.
