Drug abuse in the U.S. Hispanic population appears to be in a dynamic state of acceleration, although there are differences in drug use patterns
An understanding of the consequences of cultural adjustments for drug use is needed to effectively anticipate the scope and dimensions of illicit
drug use in the largest, rapidly growing, minority group in the U.S.
This paper provides an epidemiologic overview of current Hispanic drug use, summarizes research on the relationship between culture change
and drug use, organized according to individual, social (i.e., family and peer group), and community level influences on drug use, and offers a
systematic agenda for future research.

Hispanics are the largest minority group in the U.S. with a
population of 40 million people (U.S. Census Bureau, 2005),
constituting 13.4% of the population. Due to high fertility and
immigration rates, this group is rapidly growing and projected
Bureau, 2004). The Hispanic population is youthful (e.g., 40%
of the population is under the age of 21), and disproportion-
ately low-income (e.g., 23% below the federal poverty line),
with limited educational attainment (e.g., more than half of His-
panics over the age of 25 have not graduated from high school)
(Ramirez and de la Cruz, 2002). Overall, the demographic pro-
file suggests that Hispanics are substantially socioeconomically
disadvantaged in ways that may increase individual vulnerabil-
ity to substance abuse. The purpose of this article is to identify
social science research initiatives that will yield data relevant

for policies and programs to effectively anticipate the scope and
dimensions of drug use in this rapidly growing minority group,
and identify culturally relevant interventions.
The agenda was developed by reviewing epidemiologic data
on the scope of substance use and disorder among Hispanics
in the U.S. and research on risk and protective factors. To pro-
vide a context for the reader, this article summarizes studies
that highlight issues unique to Hispanics and were most influ-
ential in our decisions about needed research. At the outset it
is important to note that the review was more extensive than
can be captured here. For example, “drug use” includes alco-
hol, tobacco, and other licit and illicit substances, each with its
own set of epidemiologic surveillance systems and literatures.
Although most Hispanics with substance use disorders have
comorbid alcohol use disorders (Vega et al., 2003), the reverse
is not true. Thus, studies focused on alcohol dependence cannot
accurately capture drug use patterns. Further, stigma is associ-
substances are likely to experience stigma in different ways,
many of which stem from involvement in criminal activity, and
stereotypes about “addicts”. Consequently, results from studies

on alcohol use among Hispanics may not be uniformly gener-
alizeable to substance abuse, and whenever possible we include
here studies that focused on illicit substances, or reported find-
ings separately for alcohol and other substances. (For a review
of illicit substances, see Galvan and Caetano, 2003).
A second criterion for including studies in this paper derives
from our assumption that it is unlikely that Hispanic drug-use
patterns are defined by factors that have not previously been
identified in the extensive body of research on risk and protec-
influences between cultural adaptation and known personal,

alcohol use was instructive (e.g., Caetano, 1987). Additionally,
the current agenda was influenced by reviews of culture change
among Hispanics that have been conducted by mental health
researchers (Escobar et al., 2000; Escobar and Vega, 2000).
The review is organized into two main sections. The first
section is a brief overview of the current epidemiology of illicit
drug use and disorder among Hispanics in the U.S. It empha-
sizes the demographic correlates of nativity (e.g., immigrant
or U.S.-born), ethnicity (person’s or parents’ country of birth),
gender, and age-related patterns of drug-use. The second sec-
tion presents studies that speak to the interplay between culture
change and drug abuse etiology, organized around individual,
social (peer and family), and community levels of influence.
Because of epidemiologic shifts in Hispanic drug use identi-
fied in section one, studies that speak to gender and age-related
risks are emphasized. Important considerations for conducting
research with Hispanics and interpreting findings are identified
in both sections. Specific suggestions for future research are
presented separately in the final section.
Annual data from respondents (persons age 12 years and
lifetime illicit substance use than non-Hispanic blacks and non-
Hispanic whites, and higher rates than Asian Americans. For
example, in 1997, the lifetime rate for Hispanics was 25.9%,
whereas the rates for blacks and whites were 31.1% and 38.2%,
respectively (SAMHSA, 1998). As of 2003, rates had increased
for all groups, although the relative ranking of lifetime use by
race-ethnicity did not change: 37% for Hispanics, 44.6% for
blacks, and 49.2% for whites (SAMHSA, 2004). With other
measures of drug use, such as current use or substance use dis-
order, there tends to be little difference between the groups,
or higher rates among Hispanics than the other two groups.
The rates of illicit substance use in the past month were sim-
ilar across the main ethnic groups: 8.0% of Hispanics, 8.3% of
whites, and 8.7% of blacks reported current illicit substance use
in 2003. With the most serious measure of drug use, substance

in the National Comorbidity Survey (which focuses on a more
limited age range (persons ages 15–54 years) than the NSDUH
and also excluded Spanish speakers), the groups did not dif-
fer from each other in the persistence of disorder (Breslau et
al., 2005). Substance use disorder in the past year among those
with a lifetime disorder was 23.3% for Hispanics and 23.6% for
National surveys restricted to adolescent populations sug-
gest that the younger the respondents, the more likely Hispanics
have higher rates of illicit substance use compared to whites
and blacks. Among eighth grade respondents in the Monitoring
the Future study, Hispanics reported the highest rates of illicit
drug use in the past year since 1992 (Johnston et al., 2004). In
2002, one fifth of eighth grade Hispanics had used an illicit sub-
stance. Roughly one-third of Hispanic and white tenth graders
reported illicit substance use, which is greater than the propor-
tion of black peers in the same grade, and the substance use
rate of Hispanic high school seniors falls between the rate of
whites and blacks. Similar patterns were found in data from the
2003 Youth Risk Behavior Surveillance Survey: among males,
(46.7%) fell between the rate reported by whites (40.5%) and
and current cocaine use was highest among Hispanics (Centers
for Disease Control and Prevention, 2004).
Data on the U.S. Hispanic population as a whole obscures
within-group variation. Hispanics are heterogeneous: About
two-thirds of the population is Mexican, followed by Cen-
tral and South American (14.3%), Cuban (3.7%), Puerto Rican
(8.6), and other (6.5%) (Ramirez and de la Cruz, 2002). Within
these groups there are further variations by nativity status,
length of stay in the U.S. and languages spoken (Borrell, 2005).

ple, data from the Monitoring the Future surveys indicate that
Cuban adolescents have the highest reported 12 month illicit
drug use rates of any ethnic group in the U.S. (Wallace et al.,

rate of 1.7% among foreign-born Mexican Americans and
12.0% among U.S.-born Mexican Americans. However,
there is suggestive evidence that differences by nativity are
not significant when samples are comprised of adolescents.

about interactions between nativity and age with regard to pro-
gression to substance dependence. A longitudinal community
study of males provides a noteworthy contribution along these
dimensions; substance use during early adolescence was asso-
ciated with substance use disorder during young adulthood, but
the risk was greatest for African Americans and foreign-born
Hispanics, the groups who reported the lowest rates of early use
(Gil et al., 2004).
An extensive set of studies also suggests that the order in
et al., 1992; Kandel, 1985; Newcomb and Bentler, 1986). Most
of this research shows that individuals who ever used an illicit
use (“gateway” substances) preceded marijuana use and depen-
dence (e.g., Kandel, 2002), and marijuana use preceded illicit
drug use and dependence (Vega and Gil, 2005). The use of an
illicit substance before a licit substance is considered to be a
breach of the normative sequence, although etiological studies
have not focused on the consequences of breaches for the devel-
opment of substance use disorder.

ent ethnic groups have not generated consistent findings. Vega

been reported based on analyses of Youth Risk Behavior Survey
trolling for other factors, the use of illicit substances before licit
female youth, compared to white youth.
Most population-based studies among adults have found
that the prevalence of substance use, abuse and dependence is
significantly higher among males than females (Anthony et al.,
1994; Hughes et al., 1997; Warner et al., 1995), and the male
to female ratio is often substantially greater among Hispanics
than non-Hispanic whites (Bachman et al., 1991; Canino et al.,
1993; Vega et al., 1998). The higher sex ratio difference among
Hispanics compared to whites has been attributed to negative
sanctions against female substance use in the traditional Latino
family (Oetting and Beauvais, 1990), and relatively more
stigma against Hispanic female compared to white female
drug users (Valdez et al., 2000). The extent to which family
processes correspond with traditional customs is likely to vary
by national origin, which may help explain why Puerto Rican
women tend to report higher rates of illicit drug use than other
Hispanic women (Amaro et al., 1990). Gender also appears
to interact with nativity and age at immigration. For example,
Mexican American women compared to Mexican immigrant
in adulthood, and exceptionally lower among Hispanic women
who were older when they moved to the U.S. (Vega et al.,

2.4. Summary of substance use epidemiology
Caution in comparing substance use prevalence estimates
across studies, regardless of the population, is warranted.

and non-comparable age groups (e.g., 12–15 years or 11–17
consequences for participation and reliability of reporting. For
comparisons within Hispanic groups, the preceding overview
reinforces the need to interpret prevalence estimates in light of
sample characteristics such as national origin, nativity, gender
and age. Research by Lillie-Blanton et al. (1993) illustrated the
importance of adjusting rates according to community context;
blacks and whites had similar cocaine use rates when they were
matched by neighborhood, but black had higher rates according
to unmatched analyses.
L.A. Warner et al. / Drug and Alcohol Dependence 84S (2006) S8–S16
With these caveats in mind, the epidemiologic data suggest
that drug abuse in the U.S. Hispanic population appears to be
in a dynamic state of acceleration. Older Hispanics report lower
but rates among Hispanic adolescents are similar to or greater
than rates among non-Hispanic white adolescents. Gender dif-
ferences in drug use rates are notable among older Hispanics,
but not younger; and, at least for some Hispanic subgroups,
substance abuse prevalence among U.S.-born adolescents is no
different from foreign-born adolescents.
3. Drug abuse risk and protective factors in evolving
same as those for drug abuse or dependence. In general, situa-
in initial substance use (U.S. Congress, Office of Technology
Assessment, 1994), whereas affective, cognitive and behavioral
dysregulation are implicated in the progression from drug use
to abuse or dependence (Dawes et al., 2000). As stated in the
Introduction, it is unlikely that Hispanic drug-use patterns are
defined by factors that have not previously been identified in
the extensive body of research on risk and protective factors,
some of which evaluates the role of culture. (See the article on
prevention research in this volume for additional coverage of
culture and drug use). Notable shifts in Hispanic demographics
and substance use patterns point to culture change as a key area
Various definitions of culture change (i.e., acculturation,
assimilation and adaptation) have been included in Hispanic
turation may operate differently for Hispanic subgroups; based
on analyses of three national surveys, acculturation was associ-
group (Wagner-Echeagaray et al., 1994). Also, the salient fea-
tures of culture change may differ for the approximately 40% of
the U.S. Hispanic population that is foreign-born (Ramirez and
de la Cruz, 2002), and Hispanics born in the U.S. but who live
in families and communities with strong cultural connections.
an individual assimilates the practices and values of the domi-
nant culture, rather than the attainment of a status (i.e., one has
adopted the host culture or not) (Coatsworth et al., 2005; De la
Rosa, 2002; LaFromboise et al., 1993). Culture change is chal-
been used in Hispanic health research, see Hunt et al., 2004),
with place of birth and number of years living in the United
States often used as proxy measures. Moreover, acculturation is
not only an individual-level process but occurs at peer, family
and community levels as well (Weigers and Sherraden, 2001),
yet how culture change operates at these other levels, and the
conditions under which it is adaptive or not, are not well under-
stood. In each of the following subsections, we describe facets
of social and cultural adjustment that are theoretically linked
to individual, family and peer, and environmental correlates of
substance use, and identify research that speaks to the influence
of culture change on drug use patterns.
3.1. Individuals, culture change, and drug use
For individuals, culture change can influence values, prefer-
ences, and attitudes about normative behavior (Betancourt and
predominate use of English rather than Spanish (Epstein et al.,
2001; Marsiglia and Waller, 2002) have been identified as cor-
positive attitudes toward drug use have been found to increase
with number of years in the U.S. (Velez and Ungemack, 1995).
Individuals’ stress exposure and coping responses are also
theoretically linked with culture change (De la Rosa, 2002). In
this area, research on mental illness is particularly instructive
and relevant, given strong evidence that psychiatric disorders
are implicated in the etiology of drug use disorders (Biederman
et al., 1997; Kessler et al., 1996; McGee et al., 2000). For exam-
ple, lower rates of mental illness among foreign-born compared
to U.S. born Hispanics have been interpreted as an “immigrant
uations that may be particularly stressful (e.g., high crime, high
U.S.-born Hispanics (e.g., Escobar et al., 2000; Ortega et al.,
2000; Vega et al., 1998). One explanation for the finding is a
selection effect: healthy people migrate, yielding a group of
immigrants who are much less vulnerable to psychosocial stres-
sors. Research on rates of drug use prior to exiting one’s home
country is not widely available, but data on age at onset of drug
use suggest foreign-born Hispanics are not likely to have used
drugs prior to leaving their countries (Vega et al., 2002).
Others have argued that foreign-born Hispanics have lower
risk for negative outcomes because they have relatively modest
expectations about what success means, whereas the U.S.-born
experience more distress given barriers to their substantially
al., 1987). According to a study of Hispanic middle school stu-
dents, immigrants viewed their current lives in comparison with
life in their home countries, where economic and social con-
ditions were often worse, but U.S.-born Hispanics were more
likely to compare themselves with their peers in the United
and Suarez-Orozco, 1995). The investigators suggested that as
a result of the different frames of reference, U.S.-born Hispanic
youth experience more distress. Substance use could be a way
of coping with this distress, or a way to gain entrance to a social
network that is perceived to be better off.
Culture change processes, if associated with exposure to
negative life events, may also factor into the development of
substance abuse. Turner and Lloyd (2003) demonstrated that
lifetime cumulative exposure to major negative life events sig-
nificantly increases risk for the subsequent onset of drug depen-
dence among Hispanics, as among other groups. Because the
study was conducted in South Florida where Hispanics are a

ied were from the relatively privileged Cuban background, the
results may not be generalizable to other Hispanics. It has been
Central American refugees and immigrants might increase the
need for mental health care in this group (U.S. Department of
Health and Human Services, 2001). It is reasonable to question
if traumas or losses surrounding immigration have distinct con-
regard to substance use as self-medication.
3.2. Families and peer groups, culture change, and drug use
Families and peers, as conduits of social control and social
learning, have important influences on drug use. In Hispanic
cultures “familism” has been identified as a uniquely defining
itive parent–child relationships are protective against drug use

tional family values, including “respeto” (respect for parents),
family support and family pride (Vega and Gil, 1998).
may contribute to the erosion of familism (Szapocznik, 1979).
Because attachment to cultural prerogatives is likely to vary
2000), youths’ drug use and other negative behavior may reflect
the strains engendered when children have greater levels of
acculturation than parents. A recent study in which a mother’s
cents’ antisocial behavior (Eamon and Mulder, 2005), supports
the notion that minimization of acculturation gaps across the
generations may be beneficial. On the other hand, caution is
warranted if parents themselves increase their substance use as
part of their acculturation.
To the extent that acculturation weakens any prohibitions
against divorce, or against unmarried women having children,
that Hispanic youth living in two parent households are signif-
icantly less likely to use substances than those living in single
parent households or with neither parent (Gil et al., 1998, 2000;
Krohn et al., 1996). Additionally, Hispanic youth from single
parent households were more likely to use alcohol or drugs than
African-American and white non-Hispanic counterparts from
single parent households (Krohn et al., 1996). There is some

in single versus two parent families had higher drug use, but
no such association was found for Cuban American adolescents

require studies that control for socioeconomic status.
The culture-related strains in parent–child relationships may
also shape opportunities for Hispanic youths to associate with
deviant peers. For example, a series of studies of Puerto Rican,
Colombian and African American adolescents shows poor
relationships with parents are related to youths’ development
of unconventional attitudes and rebelliousness, which in turn
increased youths’ vulnerability to deviant peers and drug use
(Brook et al., 1998a; Chappin and Brook, 2001). Other research
on linguistic acculturation (e.g., youths’ use of English to com-
municate with parents) identified that peers’ drinking norms
mediated the relationship between acculturation and polydrug
use (Epstein et al., 2003).
vious section that substance use may be a way to gain entrance
to a more desirable social network. Krohn et al. (1996) showed
that Hispanic alcohol users were less likely to have friends from
their own ethnic groups than non-alcohol users, lending sup-
port to the argument that greater acculturation, vis-` a-vis greater
numbers of friendships with non-Hispanic youth than Hispanic
youth, may be related to increased substance use in Hispanic
The impact of acculturation on Hispanic women’s traditional
roles within the family, and related consequences for women’s
drug use patterns are more difficult to predict. On one hand,
women who use drugs are severely stigmatized because of cul-
turally embedded gender norms (Mora, 2002) that may not
readily change. On the other hand, the stressors associated with
acculturation might establish countervailing pressures toward
ners, given research that points to the influential role that males
play in women’s initiation and persistent use of drugs (Amaro

3.3. Communities, culture change, and drug use
Family and social networks are embedded in larger com-
munity contexts, and there has been increasing attention to the
mate the association between individuals’ perceptions of social
capital in the community, such as collective efficacy, and public
health outcomes (e.g., Kawachi et al., 1999). Evidence suggests
that social capital may be relatively higher in predominately
Hispanic communities, and thus may be a particularly impor-
tant focus for future studies of Latino drug use. For example,
the pernicious effects of poverty in some neighborhoods may
be neutralized by high levels of residential stability and home-
ownership in low-income Hispanic communities (Ross et al.,
2000). Other studies have focused on the neighborhood as the
unit of analysis, and examined the way characteristics, such as
level of poverty, may predict outcomes that are correlated with
drug abuse, such as depression (Wight et al., 2005), but not drug
sures found that marital status of parents, immigrant generation
L.A. Warner et al. / Drug and Alcohol Dependence 84S (2006) S8–S16
and dimensions of neighborhood social context accounted for
the differences in rates of violence between black, white, and
Hispanic youth (Sampson et al., 2005).
Given the relatively recent gains that have been made in our
understanding of contextual influences on health, it is not sur-
prising that changes in social context have yet to be examined
in any consistent way. Similarly, change in the cultural con-
text of communities or neighborhoods, and its association with
drug use patterns, is unexplored. Studies conducted along the
U.S.-Mexico border support the assumption that culture change
processes at the community level relate to drug use. For exam-
ple, according to a survey of primarily Mexican adolescents
in schools on both sides of the Texas-Mexico border, rates of
depressive symptoms, drug use, and suicide were high in both
drug use than youth residing in Mexico (Swanson et al., 1992).
Case studies of drug abuse and community capital, like those
conducted by Valdez et al. (1997) in Laredo, Texas, promise to
be an important methodology for developing hypotheses about
communities in transition, and their vulnerability to drug abuse.
4. Research agenda
The last several years have witnessed substantial advances
in research on drug abuse among Hispanics in the U.S., includ-
ing federal support for studies that oversample minority groups,
and thus allow for sufficient sample size to investigate within
group profiles, and design strategies that improve data reliabil-
ity, such as Spanish-language interview protocols and measures
(e.g., Alegr´ ıa et al., 2004a,b). Understanding the complex inter-
in this review requires commitment to a research agenda that
crosses geographic borders, includes researchers from multiple
ponent of the research agenda is described in more detail below,
and specific questions are offered.
4.1. Crossing borders
Research must have the capacity to manage variations in
and different geographic areas (e.g., rural and small towns,
border areas, and densely populated metropolitan areas) and
cation studies conducted in Hispanic communities with diverse
characteristics are needed.
two reasons. First, a substantial proportion of Hispanics were
not born in the U.S. Consequently the epidemiology of drug use
in this country is structured to some extent by prevailing drug
use patterns in the countries of origin, as well as social norms
and attitudes about gender- and age-appropriate behavior. Tests
of hypotheses about the stresses and consequences of culture
change could be more rigorous with epidemiological data from
the sending countries. Second, Hispanics who come to the U.S.
to work, but do not intend to stay, constitute a unique and pos-
sibly highly vulnerable sub-group. It is possible that drug use
back to their nations of origin, with unknown consequences for
indigenous populations (Vega et al., 1998).
4.2. Input from multiple disciplines
Immigration and culture change processes are likely to be
extremely sensitive to chronological age insofar as it is a proxy
for developmental level and exposure to life stress. Expertise
from multiple disciplines is needed to evaluate the components
of that statement. Cultural anthropologists, psychologists and
sociologists have unique perspectives on development within
context, and discipline-specific models of stress and coping. In
a collaboration across disciplines, the relative contribution to
drug abuse of such things as values, norms, role functioning,
deviance, abnormal development, and stigma can be systemati-
A related line of inquiry focuses on the interplay between
exposure to stressors, psychiatric illness and drug dependence.
There is a pressing need for research to evaluate variations in
stress exposure and stress vulnerability among Hispanics of
differing national origins. The incorporation of biogenetic fac-
requires insight from basic and applied sciences, including neu-
robiology and psychiatry. (See a review of biological research
on drug abuse and addiction in this issue).
Finally, each discipline has its own experts on alcohol,
tobacco, and psychotropic drugs, as well as illicit substances.
In addition to engaging all substance-specific researchers in the
design and implementation of studies that advance this research
agenda, it would be extremely helpful to have formal arrange-
ments for ongoing cross-substance dissemination of research
that speaks to culture change processes.
4.3. Application of multiple research methods
Methodological considerations are paramount for three top-
ics in the research agenda: culture change and developmental
processes at the individual level, the experiences and meaning
of culture shifts among women and families, the measurement
of culture change at community levels.
Longitudinal studies of Hispanics are necessary to isolate
ages at which acculturation processes have an impact, and when
the risk for progression from use to abuse may be greatest.
Although initiation of substance use in adulthood is rare, other
changes in drug use patterns are more likely, and longitudi-
nal designs should capture broad age ranges across multiple
cohorts. These design features would help identify conditions
and ages when substance use escalates to dependence, or when
persons mature out of illegal drug use. For adolescents in par-
ticular, who experience tremendous transitions in identity and
value formation, narrowly spaced observation points are critical
to our understanding of dynamic processes such as adolescent
socialization and acculturation.
Ethnographic and qualitative studies are needed to under-
L.A. Warner et al. / Drug and Alcohol Dependence 84S (2006) S8–S16
vary with national origin. For example, given evidence that
U.S.-born Latino parents have much higher drug use rates than
foreign-born Latinos (Vega and Sribney, 2003), it is important
to reexamine family dynamics, and reevaluate the accultura-
tion gap hypothesis. Qualitative study might also help identify
aspects of culture change and social and economic assimilation
that influence drug use because of their main effects on family
functioning. For example, some responses to limited economic
be probed through interviews and observation.
Qualitative studies are also well suited to give voice to
Hispanic women and girls about the complicated negotiations
around gender roles, expectations, and substance use. In par-
ticular, research on the negative consequences of acculturation
on familism suggests that maintaining more traditional family
roles may be protective, at least with regard to youths’ drug use.
It would be important to know the extent to which support for
traditional family roles may have unintended consequences for
women, possibly by encouraging them to stay in unhealthy rela-
tionships with partners who are themselves using substances.
Community factors are arguably the least understood influ-
ences on individual drug use behavior, and there are many more
questions than there are data about interrelationships between
shifting neighborhood demographics, cultural norms, and drug
use. A set of measures that captures drug activity at the commu-
nity level, as well as changes in culture, needs to be developed.
Surveys of community residents can be used to collect data on
such factors as tolerance in the community for drug use, per-
ceived availability of drugs and drug treatment services, and
drug use in social networks. Records on arrests, drug mentions
in emergency room visits, and actual availability of drugs and
drug treatment services can also be used to gauge community
level drug use indicators. Changes in culture could be gauged,
is foreign-born, and primarily Spanish speaking.
With collaboration across sites, as described above, it would
be possible to maximize cost-effectiveness, explanatory value
and statistical power. This in turn would facilitate testing differ-
ences between unique subgroups and establish opportunities to
aggregate data to test hypotheses about culture change and risk
and resilience at the individual and community levels.
