Which of the following is NOT a method used to identify substance abusers?

The correct answer highlights that social media monitoring is not a recognized or standard method for identifying substance abusers within the context of military practices. Rather, methods like medical care referrals, self-identification, and commander's identification are established approaches to assist in identifying individuals who may be struggling with substance abuse issues.

Medical care referrals involve healthcare professionals identifying potential substance abuse problems during medical evaluations or treatment sessions. This method ensures that individuals receive proper care and support based on medical expertise.

Self-identification relies on individuals acknowledging their own substance use issues, which can be a crucial step toward seeking help. This method empowers individuals and encourages them to take responsibility for their health.

Commander's identification occurs when a commanding officer or supervisor recognizes signs of substance abuse in a service member. This may involve behavioral observations that lead to referrals for further evaluation or support services.

In contrast, social media monitoring is not a formal or reliable means of identifying substance abuse and may raise ethical concerns regarding privacy and the appropriateness of surveillance. This differentiates it from the other methods, which focus on direct engagement and support.
