The Division of Criminal (DCI) Investigation Narcotics Bureau is a statewide drug enforcement agency that initiates and conducts all types of dangerous-drug investigations throughout the state. The Narcotics Bureau also provides investigative assistance at the request of city, county, state and federal law enforcement agencies within Montana and in neighboring states.

Narcotics Bureau agents also investigate organized criminal activity and assist other DCI bureaus in their investigations.

Montana’s dangerous drug statutes are found in Title 45, Chapter 9 of the Montana Code Annotated.

• non-drug investigations like murder-for-hire, weapons violations, fugitive apprehension and anti-government organizations
