What could a weird smell suggest regarding Brady's condition?

A weird smell can suggest possible substance use because certain drugs, alcohol, or intoxicating substances may produce distinct odors that can be noticeable. For example, the smell of alcohol on a person’s breath or certain drugs can emit unique scents, indicating that the individual may be under the influence. Identifying these smells is crucial for a law enforcement officer, as it may guide them in assessing the situation and determining whether further investigation or intervention is necessary regarding the individual's state of being.

In contrast, while excessive perspiration can have a smell, it is often not categorized as "weird" in the same manner that substance-related odors are. Freshly used cologne typically has a recognizably pleasant smell and wouldn’t usually be described as weird in this context. Exposure to chemicals may yield unusual odors, but this is generally more specific and can often be assessed through visibility of chemical substances or the individual’s environment rather than a personal scent typically associated with substance abuse. Therefore, the recognition of a weird smell aligns most closely with the implications of potential substance use.
