Spain is the main gateway into Europe for cocaine and hashish and people are constantly trying to make a quick dollar (or euro) by smuggling these drugs into the country.

A recent International Narcotics Control Board study showed that 27 of the total 35 tonnes of cannabis plants coming into Europe were detected in Spain in 2010.
For cocaine, meanwhile, 25 of the total 60 tonnes intercepted in Europe were in this country.
