Only those inmates who have been in office custody for how many days will be subject to random drug testing?

The correct answer is based on best practices and policies related to inmate management and testing protocols in detention facilities. Random drug testing is typically implemented after a certain duration of custody to ensure that the tests assess long-term behavior rather than short-term fluctuations.

In this context, the duration specified is 30 days. This timeframe allows sufficient time for baseline behavior to be established while also serving as a deterrent against drug use among inmates. By waiting for 30 days, the facility can ensure that inmates have settled into their custody environments, which is important for the reliability of the testing and to monitor compliance with rules regarding substance use.

Choosing a shorter duration, such as 15 days, could lead to inconsistencies in results due to potential short-term use immediately after arrival. On the other hand, a longer duration like 45 or 60 days may not be practical for a regular testing schedule and might lead to missed opportunities for timely intervention if an inmate is using substances. Thus, 30 days strikes a balance that supports effective management and monitoring within the facility.
