"At approximately $160 million in 2007, the estimated total spending on HIV-related harm reduction in low and middle income countries is extremely low, and would still be insufficient even if this figure was underestimated by a factor of two or three. It amounts to about three US cents a day, or $12.80 a year, for each person who injects drugs. It is clearly inadequate when compared with indicative unit costs of providing needles and syringes (approximately $100 per person per year) and methadone (approximately $500 per person per year)."
