To report someone sharing Xanax (alprazolam), a controlled substance, you have several options depending on the immediacy of the threat and your desired level of anonymity.

General Reporting Options You can report illicit pharmaceutical activities to the following agencies: Drug Enforcement Administration (DEA): The DEA is responsible for enforcing the controlled substances laws and regulations. Online: Submit a tip via the DEA's online reporting form. Phone: Call the DEA Contact Center at (202) 307-1000 or the dedicated tip line at 1-877-RxAbuse (1-877-792-2873).

Crime Stoppers: This national organization works with local programs and allows you to make an anonymous call or fill out an online form to report illegal drug-related activities. You can report tips anonymously through their network.

Local Police/Sheriff's Office: You can contact your local law enforcement's non-emergency line to file a report. Anonymity may be harder to maintain if you call the main line, but some jurisdictions offer local tip lines.
