A person intoxicated in public admits to using marijuana. What should the officer do?

When a person is publicly intoxicated, it is the officer's responsibility to ensure public safety and enforce the law regarding public intoxication. In this scenario, the individual has admitted to being intoxicated in public, which typically constitutes a violation of local laws that prohibit this behavior, especially if they pose a risk to themselves or others.

By opting for an arrest for public intoxication, the officer is taking the necessary action to manage the situation in a manner that protects the individual and the community. This intervention can also provide an opportunity for the individual to receive further assistance regarding their alcohol or substance use if necessary. Addressing public intoxication through arrest allows for proper documentation and processing according to legal protocols, thereby ensuring accountability under the law.

The other options do not adequately address the situation's seriousness; letting the individual go home may not be safe or responsible, charging them solely for possession of marijuana may not be applicable depending on local law regarding personal use, and issuing a ticket for loitering does not directly address the public intoxication or the immediate risks it poses.
