Drug Addiction Rises in Myanmar's Kachin State Steve Sandford KACHIN STATE, MYANMAR - The clanking sound of leg irons shackled around the ankles of the unwilling patients signals the arrival of a small group of heroin addicts at the mess hall located inside a fortified Pat Ja San compound near Laiza in Myanmar's Kachin state, located in the country's north along the border with China. The compound is one of 28 run in Kachin and neighboring Shan state by Pat Ja San, a Christian anti-drug vigilante group. International observers say treatments at the rehabilitation centers are rudimentary and brutal compared to modern Western methods. The detoxification program often includes locking patients in barred rooms and confining their legs to wooden stocks to prevent escape during the initial treatment when addicts experience the painful effects of withdrawal. Methadone is sometimes available, but medical training for the workers and access to modern drugs are limited, especially in the rural areas where military battles persist. 'Drug is everywhere' Lahtaw Ah Li, 22, is a new arrival. At 14, he began working at a jade mine in Hpakant township in Kachin state, where most of the industry is concentrated, scavenging through discarded rock piles for bits of the valuable gem. A few years later, he started using heroin to cope with the long hours. "The drug is for sale everywhere around the mine sites, and it's cheap to buy," Ah Li said about heroin, which costs about 75 cents per injection. Drug camps, or "shooting galleries," are openly set up in the mining areas, supplying users with syringes and cheap heroin to inject or inhale. Corruption is rife in the region. Some law and mining officials illegally distribute the drug, which is largely smuggled in from neighboring Shan state, according to the Burma Campaign UK. After his family persuaded him to return to the rehabilitation camp for internal refugees near Laiza where they lived, Ah Li kept using the drug until he tested positive during a roadside stop run by the Pat Ja San. Most checkpoints in Kachin have an outhouse or hut where urine samples are taken immediately. "I only use drugs while I'm working at the jade mine and searching for jade," Ah Li said. In 2012, renewed fighting between Myanmar's military and the Kachin Independence Army forced Ah Li and his family from their village near Laiza in Kachin state. The KIA is one of the ethnic armies battling Myanmar's military in conflicts in several parts of the country over autonomy and control of resources. WATCH: Drug addiction .
