The main route of entry of marijuana to Cuba is the “recalos” (drug packages that enter by the sea) wich destination is not Cuba. These are usually boats that go to the United States from Jamaica. The drug traffickers some times are stopped along the way and, in order not to be arrested, they throw the drug into the sea. And due to marine currents, the packages come to Cuba.
She also acknowledges that Cubans grow marijuana in the eastern region of Cuba.
