As in other periods, as long as governments imposed restrictions
on imports, people tried to smuggle goods. New 20th century
transport methods, particularly international air travel and
the Channel Tunnel, have made smuggling easier.
In the early 20th century import duties on brandy, gin and
cigarettes meant it was worth smuggling them. Then the increased
demand for illegal drugs, and the huge amounts of money to
be made, attracted smugglers. By the end of the century, immigration
restrictions created the most bizarre smuggling of all: human
beings wanting to enter Britain.
