When suspicion of alcohol or drug use arises, what critical information should flight attendants gather?

Gathering information on what substances were taken, when they were taken, and the quantity involved is critical for several reasons. First, this information aids in assessing the level of impairment and potential danger to both the individual and those onboard. Understanding the specific substance can determine the appropriate response or intervention necessary. Different drugs and alcohol have varied effects, and timelines can indicate how intoxicated the person may be.

Additionally, knowing how much was consumed is vital because it influences the severity of any potential medical complications and can guide emergency responders if further intervention is needed. This information can significantly influence how crew members manage the situation to ensure safety for all passengers and crew, as well as help in reporting protocols that may follow.

The other options provide useful information in certain contexts, but they do not directly address the immediate concerns related to substance use and its implications on safety and health. Therefore, focusing on the details of substance use is pivotal in managing such incidents effectively.
