Between 2002 and 2018, the United States allocated $8.87 billion to counternarcotics efforts in Afghanistan, focusing on eradication, seizure, and alternative crops. Despite significant investments, Afghanistan emerged as the primary global opium supplier, responsible for 80% of opium production. Available data from 2001 to 2020 show that successful eradication and interdiction measures led to the destruction of 85,411 hectares of poppy fields and seizures of 679.05 tons of opium, yet cultivation reached 3,238,000 hectares and production reached 105,585 tons during the same period. The promotion of alternative crop projects inadvertently facilitated opium cultivation in some areas, as foreign aid empowered recipients to exploit resources contrary to their intended goals. Insecurity, weak governance, corruption, and the involvement of the elite are some of the factors for increased opium cultivation in Afghanistan. We argue that methods of foreign aid delivery, coupled with these four factors, rendered the whole enterprise of counternarcotics efforts ineffective.
