This is a notable change to the previous, more predictable pattern of drug testing and is another reason your name may come up more often. Additionally, most of the drugs metabolize quickly from the blood, making it more difficult to detect drug use over the long term. This is similar to testing blood for alcohol level. For example, a person's blood alcohol level may be substantial if tested soon after suspicion of driving under the influence, but the body will metabolize the substance from the blood and several hours later result in a different reading. The same holds true for illicit drugs which are quickly metabolized from the blood.
