This is because Colombia is the second largest producer of cut flowers in the world. The flower industry is a major source of income for the country, and it has been linked to the drug trade. Drug cartels in Colombia have used the flower industry as a way to launder money and transport drugs.
To combat this, the US government has implemented strict regulations on the import of flowers from Colombia. These regulations include requiring importers to register with the US Drug Enforcement Administration (DEA) and to submit to regular inspections. In addition, the DEA has agents stationed in Colombia who work with the Colombian government to investigate drug trafficking and money laundering.
As a result of these efforts, the amount of drugs being smuggled into the US through the flower industry has decreased significantly. However, the flower industry in Colombia is still considered to be a high-risk industry for drug trafficking.
So, when you buy flowers for your mom this Mother's Day, be aware that they may have a connection to the US war on drugs.
