What does pre-employment drug screening typically analyze?

Pre-employment drug screening primarily focuses on identifying the presence of substances that could impair an individual's ability to perform their job safely and effectively. This screening is intended to ensure that candidates do not use drugs that are known to affect judgment, coordination, and overall performance in the workplace.

The basic panel typically includes substances such as marijuana, cocaine, opiates, amphetamines, and phencyclidine (PCP), among others. Detecting these drugs is crucial for maintaining a safe work environment, particularly in roles that involve operating heavy machinery, driving, or critical decision-making responsibilities. This practice is standard in many industries to mitigate risks associated with drug use and align with policies regarding workplace safety and productivity.

The other options, while relevant in different contexts, do not pertain to what pre-employment drug screenings investigate. Employee work performance and personality traits relate more to an individual's suitability based on their previous work habits and integrity, while historical employment records provide insight into a candidate's job history rather than their current state concerning substance use.
