The 25-year-old North Korean man knew there would be no turning back once he escaped from North Korea across to the Chinese side of the frozen Tumen River. It was February 2009 and he knew he'd need to be swift to avoid detection by the armed North Korean and Chinese border guards.

He says only one thing could give him that clarity—the narcotic crystal meth, or methamphetamine.

"I inhaled about ten hits before I went to the river," said the man, who now lives in Seoul and asked for his name not to be used. "I felt really focused, all I could think was go, go, go. I didn't sleep for two days after that."

Before his defection to South Korea, he says he used the drug, known as "bingdu" or "ice" in the North, off and on for about three years. He says it was easy to score, dealers worked the streets of his hometown of Hamhung, South Hamgyung Province.
