Rapid screening can allow detection of drugs that might metabolize quickly and not be detectable at a later screening. For example, a drug that decreases mortality from 10% to 5% decreases absolute mortality by 5% but decreases relative mortality by 50% (ie, a 5% death rate indicates 50% fewer deaths than a 10% death rate). One goal in drug development is to have a large difference between the dose that is efficacious and the dose that causes adverse effects. A variety of drugs can be tested for in blood: examples include alcohol, amphetamines, cocaine, fentanyl, marijuana, methamphetamines, opiates, phencyclidine, nicotine, and tramadol.
