Illicit drug trafficking, moving hundreds of tons of drugs around the world, besides using organized crime distribution rings, also depends on younger tourists and poor people, of whom tens of thousands illegally transport drugs each year.
Twenty percent of women in prison in the UK are drug couriers. At one prison 120 inmates, around half, are drug smugglers from Third World countries, one third of them Nigerian. Their average sentence is six years and they face an additional five years on their return to Nigeria. Most are not professional drug traffickers, not even drug users, but women from poor circumstances who were tempted by money in ignorance of the risk.
