In 2016, a total of 63,632 persons died from drug overdoses in the United States (
1
). Drug overdose deaths involving cocaine, psychostimulants with abuse potential (psychostimulants),
or both substances combined increased 42.4% from 12,122 in 2015 to 17,258 in 2016.*
Psychostimulants with abuse potential include drugs such as methamphetamine, 3,4-methylenedioxy-methamphetamine
(MDMA), dextroamphetamine, levoamphetamine, methylphenidate (Ritalin), and caffeine.
From 2015 to 2016, cocaine-involved and psychostimulant-involved death rates increased
52.4% and 33.3%, respectively (
1
). A total of 70,237 persons died from drug overdoses in the United States in 2017;
approximately two thirds of these deaths involved an opioid (
2
). CDC analyzed 2016–2017 changes in age-adjusted death rates involving cocaine and
psychostimulants by demographic characteristics, urbanization levels, U.S. Census
region, 34 states, and the District of Columbia (DC). CDC also examined trends in
age-adjusted cocaine-involved and psychostimulant-involved death rates from 2003 to
2017 overall, as well as with and without co-involvement of opioids. Among all 2017
drug overdose deaths, 13,942 (19.8%) involved cocaine, and 10,333 (14.7%) involved
psychostimulants. Death rates increased from 2016 to 2017 for both drug categories
across demographic characteristics, urbanization levels, Census regions, and states.
In 2017, opioids were involved in 72.7% and 50.4% of cocaine-involved and psychostimulant-involved
overdoses, respectively, and the data suggest that increases in cocaine-involved overdose
deaths from 2012 to 2017 were driven primarily by synthetic opioids. Conversely, increases
in psychostimulant-involved deaths from 2010 to 2017 occurred largely independent
of opioids, with increased co-involvement of synthetic opioids in recent years. Provisional
data from 2018 indicate that deaths involving cocaine and psychostimulants are continuing
to increase.
†
Increases in stimulant-involved deaths are part of a growing polysubstance landscape.
Increased surveillance and evidence-based multisectoral prevention and response strategies
are needed to address deaths involving cocaine and psychostimulants and opioids. Enhancing
linkage to care, building state and local capacity, and public health/public safety
collaborations are critical components of prevention efforts.
Drug overdose deaths were identified in the National Vital Statistics System multiple
cause-of-death mortality files,
§
using International Classification of Diseases, Tenth Revision (ICD-10) underlying
cause-of-death codes X40–X44 (unintentional), X60–X64 (suicide), X85 (homicide), or
Y10–Y14 (undetermined intent). Among deaths with drug overdose as the underlying cause,
the type of drug is indicated by the following ICD-10 multiple cause-of-death codes:
cocaine (T40.5); psychostimulants with abuse potential (T43.6); opioids (T40.0–T40.4,
and T40.6)
¶
; and synthetic opioids other than methadone (T40.4). Some deaths involved more than
one type of drug; these deaths were included in the rates for each drug category.
Thus, categories were not mutually exclusive.**
Age-adjusted death rates
††
were examined for the period 2016– 2017 for cocaine and psychostimulants. Death rates
were stratified by age group, sex, race/ethnicity, urbanization level,
§§
U.S. Census region,
¶¶
and state. State-level analyses were conducted for 34 states and DC, all of which
had adequate drug-specificity data recorded on death certificates for 2016 and 2017.***
Analyses comparing changes in death rates from 2016 to 2017 used z-tests when deaths
were ≥100 and nonoverlapping confidence intervals based on a gamma distribution when
deaths were <100.
†††
Trends in age-adjusted cocaine-involved and psychostimulant-involved death rates from
2003 to 2017 were analyzed overall, and with and without any opioids and synthetic
opioids, using Joinpoint regression.
§§§
Changes presented represent statistically significant findings unless otherwise specified.
In 2017, among 70,237 drug overdose deaths that occurred in the United States, 13,942
(19.8%) involved cocaine, representing a 34.4% increase from 2016 (Table). Nearly
three fourths (72.7%) of cocaine-involved deaths in 2017 also involved opioids. Cocaine-involved
death rates increased among both sexes and among persons aged ≥15 years, non-Hispanic
whites (whites), non-Hispanic blacks (blacks), and Hispanics. The largest relative
rate change occurred among females aged 15–24 years (40.0%), and the largest absolute
rate change was among males aged 25–44 and 45–64 years (increase of 2.7 per 100,000).
Among racial/ethnic groups, the highest rate of cocaine-involved deaths in 2017 occurred
in blacks (8.3 per 100,000), who also experienced the largest relative rate change
(36.1%) compared with 2016. By urban-rural status, counties in medium metro areas
experienced the largest absolute rate increase (1.3 per 100,000) in 2017, whereas
the largest relative rate increase occurred in micropolitan counties (57.9%). The
Midwest Census region had the largest relative rate increase (43.6%), whereas the
highest 2017 rate was in the Northeast (7.0 per 100,000). Death rates involving cocaine
increased in 15 states, with the largest relative increases in Wisconsin (84.6%) and
Maryland (72.0%), and the largest absolute rate increases in Ohio (3.9) and Maryland
(3.6). In 2017, the highest death rates were in DC (17.6) and Ohio (14.0).

* Deaths are classified using the International Classification of Diseases, Tenth
Revision (ICD–10). Drug overdose deaths are identified using underlying cause-of-death
codes X40–X44, X60–X64, X85, and Y10–Y14. Rates are age-adjusted using the direct
method and the 2000 U.S. standard population, except for age-specific crude rates.
All rates are per 100,000 population.
† Drug overdose deaths, as defined, that have cocaine (T40.5) as a contributing cause.
§ Drug overdose deaths, as defined, that have psychostimulants with abuse potential
(T43.6) as a contributing cause.
¶ Categories of deaths are not exclusive because deaths might involve more than one
drug. Summing of categories will result in more than the total number of deaths in
a year.
** Drug overdose deaths, as defined, that have any opioid (T40.0–T40.4, and T40.6).
†† Data for Hispanic origin should be interpreted with caution; studies comparing
Hispanic origin on death certificates and on census surveys have shown inconsistent
reporting on Hispanic ethnicity. Potential race misclassification might lead to underestimates
for certain categories, primarily American Indian/Alaska Native non-Hispanic and Asian/Pacific
Islander non-Hispanic decedents. https://www.cdc.gov/nchs/data/series/sr_02/sr02_172.pdf.
§§ By 2013 urbanization classification https://www.cdc.gov/nchs/data_access/urban_rural.htm.
¶¶ Analyses were limited to states meeting the following criteria: For states with
very good to excellent reporting, ≥90% of drug overdose deaths mention at least one
specific drug in 2016, with the change in drug overdose deaths mentions of at least
one specific drug differing by <10 percentage points between 2016 and 2017. States
with good reporting had 80% to <90% of drug overdose deaths mention of at least one
specific drug in 2016, with the change in the percentage of drug overdose deaths mentioning
at least one specific drug differing by <10 percentage points between 2016 and 2017.
States included also were required to have stable rate estimates, based on ≥20 deaths,
in at least one drug category (i.e., cocaine and psychostimulants with abuse potential)
in both 2016 and 2017.
*** Absolute rate change is the difference between 2016 and 2017 rates. Percentage
change (i.e., relative change) is the absolute rate change divided by the 2016 rate,
multiplied by 100. Nonoverlapping confidence intervals based on the gamma method were
used if the number of deaths was <100 in 2016 or 2017, and z-tests were used if the
number of deaths was ≥100 in both 2016 and 2017. Note that the method of comparing
confidence intervals is a conservative method for statistical significance; caution
should be observed when interpreting a nonsignificant difference when the lower and
upper limits being compared overlap only slightly. Confidence intervals for 2016 and
2017 rates of cocaine-involved deaths for Asian/Pacific Islanders overlapped only
slightly: (0.35–0.54), (0.53–0.76) Confidence intervals of 2016 and 2017 rates of
deaths involving psychostimulants with abuse potential for Virginia overlapped only
slightly: (0.71–1.13), (1.10–1.60).

During 2003–2017, rates for all cocaine-involved deaths peaked initially in 2006,
decreased during 2006–2012, and increased again during 2012–2017. Rates of overdose
deaths involving cocaine and any opioid increased from 2013 to 2017, and those involving
cocaine and synthetic opioids increased from 2012 to 2017 (Figure 1). Cocaine-involved
death rates without any opioid decreased from 2006 to 2012 and then increased from
2012 to 2017, whereas cocaine-involved death rates without synthetic opioids increased
from 2003 to 2006, decreased from 2006 to 2010, and then increased from 2010 to 2017
(Figure 1).

In 2017, a total of 10,333 deaths involving psychostimulants occurred, representing
14.7% of drug overdose deaths and a 37.0% increase from 2016 (Table). During 2016–2017,
the age-adjusted rate for psychostimulant-involved deaths increased by 33.3%. Approximately
half (50.4%) of psychostimulant-involved deaths also involved opioids in 2017. Psychostimulant-involved
death rates increased among both sexes and among persons aged ≥15 years, whites, blacks,
non-Hispanic American Indians/Alaska Natives (AI/AN), non-Hispanic Asian/Pacific Islanders
(A/PI), and Hispanics. The largest relative rate increase occurred among females aged
25–44 years (48.0%). Among racial/ethnic groups, the largest relative rate increase
occurred among whites (40.0%), whereas AI/AN experienced the largest absolute rate
increase (1.6 per 100,000) and the highest death rate (8.5) in 2017. Counties in medium
metro areas experienced the largest absolute rate increase (1.3 per 100,000), and
the largest relative rate increase (46.4%). Among Census regions, both the largest
relative increase (63.2%) and the largest absolute rate increase (1.2) occurred in
the Midwest, whereas the highest psychostimulant-involved death rate (5.3) occurred
in the West. Death rates increased in 17 states, with the largest relative increases
in Ohio (130.4%) and West Virginia (94.3%), and the largest absolute rate increases
in West Virginia (6.6 per 100,000) and Kentucky (3.3). In 2017, the highest death
rates were in West Virginia (13.6 per 100,000) and Alaska (9.1).
During 2003–2017, rates for all psychostimulant-involved deaths increased from 2010
to 2017. Death rates involving psychostimulants and any opioid increased from 2003
to 2010, followed by sharper increases from 2010 to 2015 and from 2015 to 2017. Death
rates involving psychostimulants and synthetic opioids increased from 2010 to 2015,
followed by a sharper increase from 2015 to 2017 (Figure 2). Rates of psychostimulant-involved
deaths without any opioid involvement increased from 2008 to 2017, and rates without
synthetic opioid involvement increased from 2008 to 2017 (Figure 2).

Discussion
Deaths involving cocaine and psychostimulants have increased in the United States
in recent years; among 70,237 drug overdose deaths in 2017, nearly a third (23,139
[32.9%]) involved cocaine, psychostimulants, or both. From 2016 to 2017, death rates
involving cocaine and psychostimulants each increased by approximately one third,
and increases occurred across all demographic groups, Census regions, and in several
states. In 2017, nearly three fourths of cocaine-involved and roughly one half of
psychostimulant-involved overdose deaths, respectively, involved at least one opioid.
After initially peaking in 2006, trends in overall cocaine-involved death rates declined
through 2012, when they began to rise again. The 2006–2012 decrease paralleled a decline
in cocaine supply coupled with an increase in cost.
¶¶¶
Similar patterns in death rates involving both cocaine and opioids were observed,
with increases for cocaine- and synthetic opioid-involved deaths occurring from 2012
to 2017. From 2010 to 2017, increasing rates of deaths involving psychostimulants
occurred and persisted even in the absence of opioids. Drug overdoses continue to
evolve along with emerging threats, changes in the drug supply, mixing of substances
with or without the user’s knowledge, and polysubstance use (
3
–
8
). In addition, the availability of psychostimulants, particularly methamphetamine,
appears to be increasing across most regions.**** In 2017, among drug products obtained
by law enforcement that were submitted for laboratory testing, methamphetamine and
cocaine were the most and third most frequently identified drugs, respectively.
††††
Previous studies also found that heroin and synthetic opioids (e.g., illicitly-manufactured
fentanyl) have contributed to increases in stimulant-involved deaths (
3
,
9
,
10
). Current findings further support that increases in stimulant-involved deaths are
part of a growing polysubstance landscape. Although synthetic opioids appear to be
driving much of the increase in cocaine-involved deaths, increases in psychostimulant-involved
deaths have occurred largely without opioid co-involvement; however, recent data suggest
increasing synthetic opioid involvement in these deaths.
The findings in this report are subject to at least four limitations. First, at autopsy,
substances tested for and circumstances under which tests are performed vary by time
and jurisdiction. Therefore, recent improvements in toxicologic testing might account
for some reported increases. Second, 15% and 12% of death certificates in 2016 and
2017, respectively, did not include mention of specific drugs involved. The percentage
of death certificates with at least one drug specified varied widely by state, ranging
from 54.7% to 99.3% in 2017, limiting comparisons across states. Third, potential
racial misclassification might lead to underestimates for certain groups, primarily
AI/AN and A/PI.
§§§§
Finally, certain trend analyses were limited, given small numbers of deaths and the
inability to calculate stable rates among some stimulant-opioid drug combinations
before 2003.
Preliminary 2018 data indicate continued increases in drug overdose deaths.
¶¶¶¶
The rise in deaths involving cocaine and psychostimulants and the continuing evolution
of the drug landscape indicate a need for a rapid, multifaceted, and broad approach
that includes more timely and comprehensive surveillance efforts to inform tailored
and effective prevention and response strategies. CDC currently funds 45 states and
DC for opioid surveillance***** and/or prevention activities.
†††††
The contribution of opioids to increases in stimulant-involved overdose deaths underscores
the importance of continued opioid overdose surveillance and prevention measures,
including existing efforts to expand naloxone availability to persons at risk for
drug overdose. CDC is expanding drug overdose surveillance efforts to include stimulants
and is implementing multiple, evidence-based opioid prevention efforts, such as enhancing
linkage to care, building state and local capacity, and public health/public safety
collaborations.
§§§§§
Because some stimulant deaths are also increasing without opioid co-involvement, prevention
and response strategies need to evolve accordingly. Increased efforts are required
to identify and improve access to care for persons using stimulants, implement upstream
prevention efforts focusing on shared risk and protective factors that address substance
use/misuse, and improve risk reduction messaging (e.g., not using alone). Continued
collaborations among public health, public safety, and community partners are critical
to understanding the local illicit drug supply and reducing risk as well as linking
persons to medication-assisted treatment and risk-reduction services.
Summary
What is already known about this topic?
Overdose deaths involving cocaine and psychostimulants continue to increase. During
2015–2016, age-adjusted cocaine-involved and psychostimulant-involved death rates
increased by 52.4% and 33.3%, respectively.
What is added by this report?
From 2016 to 2017, death rates involving cocaine and psychostimulants increased across
age groups, racial/ethnic groups, county urbanization levels, and multiple states.
Death rates involving cocaine and psychostimulants, with and without opioids, have
increased. Synthetic opioids appear to be the primary driver of cocaine-involved death
rate increases, and recent data point to increasing synthetic opioid involvement in
psychostimulant-involved deaths.
What are the implications for public health practice?
Continued increases in stimulant-involved deaths require expanded surveillance and
comprehensive, evidence-based public health and public safety interventions.
