There have been claims that some Gibraltarian motorboats are engaging in drugs and tobacco smuggling. However, since 1996 there has been a law in Gibraltar controlling fast launches licensing their ownership and importation and prohibiting the entry of unlicensed craft into Gibraltar waters. In 2014, inspectors from the EU's fraud office OLAF wrote to the Spanish governments urging an investigation of tobacco smuggling, amid revelations that Gibraltar, with a population of less than 30,000, imported 117 million packets of cigarettes in 2013. In 2015, Spanish authorities broke up a major tobacco smuggling operation, seizing 65,000 packs of cigarettes, five boats, two firearms, communications equipment and €100,000 cash. Authorities estimated the group was smuggling 150,000 packs of contraband tobacco into Spain every week.
