The eradication (the physical destruction) of illicit crops remains an important tool for decreasing the production of illegal drugs and preventing them from entering the United States, or other drug markets.

Lack of government authority in parts of certain countries makes it easier for farmers to grow illicit crops, and eradication can help pave the way for improved, long-term government presence which leads to increased security. This reduces the influence of criminal organizations, and encourages the growth of licit crops and businesses.

INL provides training, equipment, and technical assistance to foreign governments to support their own aerial and manual eradication programs, and address related counternarcotics and law enforcement challenges. INL supports eradication programs in ColombiaPeruGuatemala, and Afghanistan.


Drug interdiction (preventing illicit drugs from reaching their destination) is important in stemming the flow of illegal drugs and countering the negative effects of organized criminal groups. INL supports interdiction efforts by partner nation law enforcement agencies through training, equipment, and technical assistance. Such efforts increase the capacity to detect, disrupt, seize, and investigate shipments of illicit drugs and the chemicals (known as precursors) needed to process and produce drugs.

In the Western Hemisphere, INL supports host nation law enforcement interdiction efforts in Mexico under the Bicentennial Framework; the Central America Regional Security Initiative (CARSI) in Central America; through the Caribbean Basin Security Initiative (CBSI) in the Caribbean; and in South America through individual bilateral programs. Interdiction, both at the source (i.e. in Colombia and Peru) and in transit plays an important role in INL programs, and augments our efforts to strengthen citizen security in the region.

In Afghanistan, INL partners with the Drug Enforcement Administration (DEA) and the Department of Defense to build the capacity of the Counter Narcotics Police of Afghanistan. There is a particular focus on support for two specialized units mentored by DEA: the Afghanistan Sensitive Investigative Unit (SIU) and the Afghanistan National Interdiction Unit (NIU) program. These specially trained and vetted groups of Afghan law enforcement officers have been successful in counternarcotics operations throughout the country. For example, evidence gathered by the SIU through court-ordered surveillance operations has increased the number and size of large-scale drug trafficking and related corruption cases brought to the Counter Narcotics Justice Center, a fully Afghan facility which receives advisory and facility operations assistance from INL, the Department of Justice, and the United Kingdom.

Drug trafficking is rampant along Pakistan’s 1,500 mile, porous border with Afghanistan and contributes to corruption, crime, and addiction throughout the country. INL collaborates with the U.S. Drug Enforcement Administration (DEA) and the U.S. Embassy’s Office of Defense Representative in Pakistan to improve the capabilities of Pakistan’s law enforcement agencies to stem the flow of narcotics. INL provides training, equipment, and operational support to law enforcement agencies including Pakistani Customs and the Anti-Narcotics Force (ANF) and supports capacity building of ANF’s Special Investigative Cell in partnership with DEA.
