What behavior could be a positive clue that a person is abusing drugs?

Repeatedly showing symptoms associated with drug abuse is a significant indicator that someone may be struggling with substance use issues. These symptoms can include changes in behavior, mood swings, withdrawal from social activities, neglect of responsibilities, and physical health changes. Observing these behaviors consistently can suggest that a person is not only using drugs but may also be experiencing dependency or addiction.

While wanting to sell valuable personal items, botching performance at work, or keeping drugs in a specific location could raise concern, they do not demonstrate the more comprehensive and chronic patterns of behavior that are typically associated with drug abuse. This makes the presence of repeated symptoms a clearer indicator of ongoing issues related to drug use.
