In The Lancet Global Health, Lindsey Hines and colleagues quantify the association between injecting drug use and development indicators. The authors found that higher rates of urban population growth were associated with older age at onset of injecting drug use (1·40 years per annual percentage change, 95% CI 0·41–2·40) and lower gross domestic product was associated with a lower median age of people who inject drugs (PWID; 0·13 years per US$1000 GDP increase, 0·06–0·20; p<0·0001) and shorter duration of injecting drug use (0·11 years per $1000 GDP increase, 0·04–0·18; p=0·002). These findings have clear implications for Sustainable Development Goal (SDG) 3, which is aimed at ensuring healthy lives and promoting wellbeing for all at all ages. One of the SDG 3 targets is to strengthen the prevention and treatment of substance abuse. Furthermore, although SDG 11 does not have specific drug use-related targets, these findings also suggest that the urban environment is an important contextual variable for injecting drug use. Moreover, urbanisation is occurring most quickly in low-income and middle-income countries (LMICs); 65·9% of countries with urbanisation rates equal to or higher than the median among urbanising countries (ie, excluding countries that have negative urban growth) in 2015 were also LMICs, suggesting a possible interaction between gross domestic product and urbanisation.

呼吁采用系统科学方法来了解城市环境中的毒品使用情况。

在《柳叶刀》全球健康杂志中，Lindsey Hines及其同事量化了注射毒品使用与发展指标之间的关联。作者发现，较高的城市人口增长率与注射吸毒时的年龄增长有关（每年1％至40年的百分比变化，95％CI 0·41–2·40），而较低的国内生产总值与年龄相关。注射毒品者的中位年龄较低（PWID； GDP每增加1000美元，增加0·13年，0·06-0·20； p <0·0001），注射毒品的持续时间较短（每1000美元增加0·11年GDP增长，0·04-0·18； p = 0·002）。这些发现对可持续发展目标（SDG）3有着明显的意义，该目标旨在确保所有年龄段的所有人的健康生活和福祉。可持续发展目标3的目标之一是加强对药物滥用的预防和治疗。此外，尽管SDG 11没有特定的与毒品使用相关的目标，但这些发现还表明，城市环境是注射毒品使用的重要背景变量。此外，在低收入和中等收入国家（LMIC），城市化发展最快。2015年，城市化率等于或高于城市化国家（即不包括城市负增长的国家）中位数的国家中，有65·9％也是低收入和中等收入国家，这表明国内生产总值与城市化之间可能存在相互作用。
