According to intelligence agencies and police reports, the purity of the crystal meth that is trafficked out of North Korea has been tested to have a 99 percent purity rate.
The production of crystal meth is a big business for the North Korean state. Intelligence agencies estimate that up to 40 percent of North Korea’s foreign trade levels comes from black market activities, of which the trafficking of crystal meth is a large portion.
In the Northern areas of the country, between 40 to 50 percent of the population is reportedly addicted to crystal meth.
