Drug Overdose Deaths Among Adolescents Aged 15–19 in 

the United States: 1999–2015 

Sally C. Curtin, M.A., Betzaida Tejada-Vera, M.S., and Margaret Warner, Ph.D. 

Key findings 

Data from the National 

Vital Statistics System 

● The death rate due to drug

overdose among adolescents

aged 15–19 more than doubled

from 1999 (1.6 per 100,000)

to 2007 (4.2), declined by 26%

from 2007 to 2014 (3.1), and

then increased in 2015 (3.7).

● The drug overdose death rate

increased between 1999 and

the mid-2000s for both males

and females but only males had

a subsequent decline between

2007 and 2014.

Drug overdose deaths in the United States are a pressing public health 

challenge (1–3). In particular, drug overdoses involving opioids have increased 

since 1999 (1). This report focuses specifically on drug overdose deaths for 

older adolescents aged 15–19. In 2015, 772 drug overdose deaths occurred 

in this age group. Rates for 1999–2015 are presented and trends compared 

for both females and males. Percent distributions of drug overdose deaths for 

2015 by intent (e.g., unintentional, suicide, homicide) are presented. Trends in 

drug overdose death rates by type of drug involved are also presented.

After increasing from 1999 through 2007, drug overdose 

death rates for adolescents aged 15–19 declined through 

2014, but then increased in 2015.

●		 The death rate due to drug overdose among adolescents aged 15–19 more than doubled from 

1999 (1.6 per 100,000) to 2007 (4.2), declined by 26% between 2007 and 2014 (3.1), and 

then increased in 2015 (3.7) (Figure 1). 

●		 For males aged 15–19, drug overdose death rates nearly tripled between 1999 

(2.1 per 100,000) and 2007 (6.2), fell by about one-third (35%) through 2014 (4.0), 

and then increased 15% in 2015 (4.6). 

●		 Similar to males, drug overdose death rates for females aged 15–19 nearly doubled between 

1999 (1.1 per 100,000) and 2004 (2.0), but were generally stable for 2004–2013, and then 

increased 35% between 2013 (2.0) and 2015 (2.7). 

●		 The drug overdose death rate for males was consistently higher than the rate for females 

during the 1999–2015 period and was 70% higher in 2015. 

The majority of drug overdose deaths in 2015 for both males and females 

were unintentional. 

●		 Of all drug overdose deaths among adolescents aged 15–19 in 2015, about eight in ten 

(80.4%) were unintentional, 13.5% were suicide, 5.2% were of undetermined intent, and 

0.9% were homicide (Figure 2). 

●		 A higher percentage of male (86.2%) than female (70.1%) overdose deaths in adolescents 

aged 15–19 were unintentional.

●		 More than one-fifth (21.9%) of drug overdose deaths among female adolescents aged 15–19 

were suicide compared with 8.7% for males. 

Rates of drug overdose deaths involving opioids among adolescents aged 

15–19 tripled from 1999 to 2007, generally declined from 2007 to 2014, and 

then increased in 2015. 

●		 The drug overdose death rate involving opioids for adolescents aged 15–19 more than 

tripled from 1999 (0.8 per 100,000) to 2007 (2.7) but was generally stable between 2007 

and 2011. The rate declined to 2.0 in 2012–2014 and then increased between 2014 and 2015 

(2.4) (Figure 3). 

●		 The rate of drug overdose deaths involving cocaine increased between 1999 (0.3) and 2006 

(0.7), declined to 0.2 in 2009, and generally stabilized from 2009 through 2013 before 

increasing between 2013 (0.1) and 2015 (0.3). 

●		 The rate of drug overdose deaths involving benzodiazepines increased from 0.1 in 2000 to 

0.7 in 2009, declined to 0.4 by 2012, and then rose again to 0.6 in 2015. 

● Drug overdose death rates involving psychostimulants with abuse potential fluctuated but 

generally increased during the period, ranging from 0.1 in 1999 to 0.4 in 2015.

Among opioids, rates of drug overdose deaths among adolescents aged 

15–19 in 2015 were highest for heroin. 

●		 The rate of drug overdose deaths involving heroin among adolescents aged 15–19 increased 

during the 1999–2015 period and was three times higher in 2015 (1.0 per 100,000) than in 

1999 (0.3) (Figure 4). 

●		 Drug overdose death rates involving opioids among adolescents aged 15–19 in 2015 were 

highest for heroin (1.0). 

●		 The death rate for natural and semisynthetic opioids, excluding heroin increased from 1999 

(0.2) to 2010 (1.2), and then declined to 0.6 in 2014–2015. 

● The rate of drug overdose deaths involving methadone was about 10 times higher in 2007 

(1.1) than in 1999 (0.1). The rate generally declined during 2007–2015, to 0.3 in 2015. 

●		 The death rate involving synthetic opioids, excluding methadone (e.g., fentanyl and 

tramadol) increased from 0.1 in 2002 (the first year in which a reliable rate could be 

computed) to 0.7 in 2015.

Summary 

Drug overdose deaths in the United States are a major public health challenge (1–3). The drug 

overdose death rate for adolescents aged 15–19 increased between 1999 and 2007, but unlike 

other age groups (1), the rate declined through 2014 before increasing in 2015. During the 

1999–2015 period, drug overdose death rates for males aged 15–19 were consistently higher than 

for females. Both male and female adolescents experienced increases between 1999 and the mid2000s but only males subsequently experienced a decline between 2007 and 2014. The rate for 

males increased between 2014 and 2015, although it was still below the 2007 peak. The majority 

of drug overdose deaths for both sexes in 2015 were unintentional, although female deaths were 

more than twice as likely as male deaths to be suicides. Overdose death rates among those aged 

15–19 were highest for opioid drugs, specifically heroin. 

When interpreting the trends reported here, it is important to remember that the total number 

of drug overdose deaths to adolescents aged 15–19 in 2015 was 772. This total number was 

smaller in some previous years. For each year, subgroup totals were even smaller. The relatively 

small numbers resulted in variability in rates, particularly in rates for specific drugs. In addition, 

during the period covered in this report, the reporting of specific drugs involved in drug overdose 

deaths among adolescents aged 15–19 was not complete, while there was also improvement in 

the reporting of these specific drugs. Both of these phenomenon could have affected the trends, 

especially for some of the specific drugs described in this report. See Data source and methods for 

more details.

Data source and methods 

Mortality and population data are from the National Center for Health Statistics’ 1999–2015 

multiple cause-of-death mortality files (4). Drug overdose deaths are those with International 

Classification of Diseases, Tenth Revision underlying cause-of-death codes X40–X44, X60–X64, 

X85, and Y10–Y14 (5). Drug overdose deaths involving opioids are drug overdose deaths with 

a multiple cause-of-death code of T40.0, T40.1, T40.2, T40.3, T40.4, or T40.6. Drug overdose 

deaths by specific drug are classified as follows: heroin (T40.1); natural and semisynthetic 

opioids, excluding heroin (T40.2); methadone (T40.3); synthetic opioids, excluding methadone 

(T40.4); cocaine (T40.5); benzodiazepines (T42.4); and psychostimulants with abuse potential 

(T43.6). Deaths might involve more than one drug, so categories are not exclusive. 

Several factors related to death investigation and reporting may affect the measurement of death 

rates involving specific drugs. For instance, there is variation in the circumstances leading to the 

performance of toxicological tests and the substances tested. This variability is more likely to 

affect substance-specific death rates than the overall drug overdose death rate. In addition, trends 

may be affected by improvements in reporting of specific drugs during the period. Over time, the 

reporting of drugs related to overdose deaths has become more specific. For adolescents aged 

15–19, reporting of a specific drug in relation to an overdose death compared with the reporting 

of no specific drug or a general class of drugs (e.g., opioids) fluctuated but generally increased 

during the period. In 2000, 73% of all drug overdose deaths had an accompanying specific drug 

mentioned; this percentage increased to 85% of drug overdose deaths in 2015. 

Trends were evaluated using the Joinpoint Regression Program (6); the z test statistic was used 

for short periods of 2–3 years at the end of the period. Death rates are per 100,000 population 

and are based on April 1 bridged-race census counts for 2000 and 2010, on July 1 bridged-race 

estimates for 1999 and 2001–2009, and on vintage 2015 postcensal estimates for 2011–2015.
