According to Human Rights Watch’s report titled The Rehab Archipelago, “Vietnam’s system of forced labor centers for people who use drugs has expanded over the last decade. In 2000, there were 56 drug detention centers across Vietnam; by early 2011 that number had risen to 123 centers. Between 2000 and 2010, over 309,000 people across Vietnam passed through the centers. The length of time in detention has also grown. At the beginning of 2000, the law provided for a person dependent on drugs to be detained for treatment from three months to a year. In 2009 the National Assembly passed a law allowing for individuals to be held for up to four years for supposed drug treatment.”
