Cut-offs and Drug Detection
Windows
The length of time that the presence of drugs of
abuse in the body can be detected is an important factor in drug screening.
The chart below outlines approximate duration times. When interpreting
the duration for the presence of drugs of abuse in the body, you must
take into consideration variables including the body's metabolism,
the subject's physical condition, overall body fluid balance,
state of hydration and frequency of usage.
The chart below shows the average duration times
of how long drugs stay in the body and are not intended to apply to
a specific individual.
