Global Estimated Prevalence of Injection Drug Use, by Region
"At a regional level, a high prevalence of injecting drug use is found in Eastern and South-Eastern Europe (1.3 per cent of the population aged 15-64), where the percentage of people who inject drugs is four times greater than the global average and which alone accounts for 21 per cent of the total number of people who inject drugs globally.
"A high prevalence rate for injecting drug use is also noted in Central Asia (1.3 per cent), which has a rate of more than four times the global average. Injecting drug use also remains a serious public health concern in a number of countries in East and South-East Asia, with the region accounting for 27 per cent of the global total. South Asia has the lowest level of injecting drug use (0.03 per cent, mostly as a result of the low prevalence rate reported in India), considerably lower than that of any other region.
"Countries and areas with the highest rates of injecting drug use – more than 3.5 times the global average — are Azerbaijan (5.2 per cent), Seychelles (2.3 per cent), the Russian Federation (2.3 per cent), Estonia (1.5 per cent), Georgia (1.3 per cent), Canada (1.3 per cent), the Republic of Moldova (1.2 per cent), Puerto Rico (1.15 per cent), Latvia (1.15 per cent) and Belarus (1.11 per cent). China, the Russian Federation and the United States are the countries with the largest numbers of people who inject drugs. Combined, they account for an estimated 46 per cent, or nearly one in two, people who inject drugs globally."
