The mortality rate in the population with SRDs (substancerelated disorders) decreased significantly over a 15-year period, from 32.4 per 1,000 in 2001-2002 to 21.6 per 1,000 in 2016-2017. A similar, but less pronounced, trend is also observable in the general population with no SRD, with the mortality rate dropping from 9.0 per 1,000 in 2001-2002 to 6.8 per 1,000 in 2016-2017.
