Introduction The war on drugs has been a common phrase in the United States for many decades. What exactly does this mean and how does it affect US foreign policy? The War on Drugs can be defined as a systematic and aggressive policy determined to undermine and stop the flow of illegal drugs into the United States. This policy is supported by several US institutions including the Central Intelligence Agency (CIA), the Federal Bureau of Investigation (FBI), the Drug Enforcement Administration (DEA), the US Army, the US Coast Guard, and US Customs. Additionally, numerous local law enforcement agencies across the country are included in this list. The United States government has established the following ways to enforce its foreign drug policy: interdiction, eradication, legislative reform. Interdiction is an attempt to stop the drug while it is on its way to the United States. This remains a daunting task; Due to the enormous size of the United States, control of its vast borders has proven extremely difficult. For example, the United States has over 12,000 miles of coastline, across 300 legal ports of entry, and over 7,500 miles of border with Canada and Mexico. Jurisdiction of these border points falls under all of the above-mentioned agencies and military branches. Here comes the first foreign drug policy problem, determining which agency/branch has legitimate control over which part of the border. The DEA and FBI have overlapping roles when it comes to enforcing drug policy. Miscommunication often occurs when attempting to interdict drugs due to overlapping jurisdiction between two government agencies. According to the Drug Policy Alliance, the United States has spent more than $25 billion on paper agreements with local cities to identify appropriate crops to exterminate. Strong legal punishment is needed to discourage drug traffickers from committing crimes. All of these crucial steps must be followed to begin winning the war on drugs.
