"In 2010 alone, the prosecution of drug offenders (for use and supply) cost at least $100 million in Russia. In comparison, under the Budget Law for 2011, HIV prevention programming is to receive less than 3% of the total $640 million to be allocated in 2012 through the Federal Budget Law for HIV, hepatitis B and C, and the government continues to prohibit internationally accepted drug treatment interventions such as OST [Opioid Substitution Treatment]. The government therefore will spend millions more treating people infected with HIV than it would have in protecting their health and reducing transmission."
