Case study: Methadone maintenance treatment in Hanoi, Vietnam.

Methadone maintenance therapy (MMT) was introduced in the rapidly developing semi-rural district of Tu Liem in Hanoi in December, 2009. Commune police play an integral role in determining which injecting drug users (IDUs) are eligible to commence and continue MMT. This case study highlights the importance of providing training to commune police about MMT to mitigate negative impacts drug law enforcement can have on IDU accessibility to MMT programs.
