Notes: 1 Significant increasing trend for 1999–2007; fluctuations, but significant decreasing trend for 2007–2014; rate for 2015 significantly higher than for 2014; p < 0.05.
2 Significant increasing trend for 1999–2009; significant decreasing trend for 2009–2012; significant increasing trend for 2012–2015; p < 0.05; too few cases in 1999 to compute a reliable rate.
3 Significant increasing trend for 1999–2006; significant decreasing trend for 2006–2009; stable trend for 2009–2013; rate for 2015 significantly higher than for 2013; p < 0.05.

Drug overdose deaths are identified with International Classification of Diseases, Tenth Revision underlying cause-of-death codes X40–X44, X60–X64, X85, and Y10–Y14. Drug overdose deaths involving opioid analgesics include drug poisoning deaths with multiple cause-of-death codes, including T40.0, T40.1, T40.2, T40.3, T40.4, or T40.6 (2015 N = 506). Drug overdose deaths involving cocaine include code T40.5 (2015 N = 70); benzodiazepines include code T42.4 (2015 N = 126); and psychostimulants with abuse potential include code T43.6 (2015 N = 82). Deaths might involve more than one drug, so categories are not exclusive. Trends may have been affected by improvement in the reporting of specific drugs for drug overdose deaths during the reporting period.
