In the first five months of 2013, customs officials seized 21.7 kilograms of methamphetamine at South Korean harbors and airports. The amount of meth seized during that time frame was higher than the total amount of meth seized in 2012.

In 2009, just 1 kilograms of the meth seized in South Korea was destined for another country. In 2011, the amount of meth destined for a third country increased to 7.8 kilograms, and rose again to 16 kilograms in 2012.
