Which of the following is an indicator of potential drug use on a person?

Unusual behavior is a significant indicator of potential drug use. Individuals who may be under the influence of drugs can exhibit a wide range of unusual behaviors that differ from their normal patterns. This can include erratic movements, sudden mood swings, paranoia, or overly excited or depressed demeanor. Such behaviors can draw attention and raise concerns among peers, coworkers, or security personnel. Recognizing these changes is crucial for security guards since their role involves monitoring for signs that may indicate someone is under the influence of substances, which could pose safety risks.

Other indicators such as increased sociability, heightened awareness, or improved physical appearance may not reliably point to drug use. For example, increased sociability could be a result of naturally outgoing personality traits or simply a social setting rather than drug influence. Heightened awareness might indicate a state of alertness without any substance use, and improved physical appearance could stem from various factors unrelated to drug use, including personal grooming or lifestyle changes. Thus, unusual behavior stands out as a more direct and discernible sign of potential drug use in individuals.
