NIDA Research Identifies Factors Related to
Inhalant Abuse, Addiction
New research shows that young people who have been treated for
mental health problems, have a history of foster care, or who already
abuse other drugs have an increased risk of abusing or becoming
dependent on inhalants. In addition, adolescents who first begin
using inhalants at an early age are more likely to become dependent
on them. The study by Dr. Li-Tzy Wu and her colleagues is published
in the October 2004 issue of the Journal of the American Academy
of Child and Adolescent Psychiatry. The study was funded by
the National Institute on Drug Abuse (NIDA), National Institutes
of Health (NIH), Department of Health and Human Services.
The most commonly used inhalants reported by participants were
glue, shoe polish, and gasoline. Other inhalants used by the participants
included nitrous oxide, lighter fluid, spray paints, correction
fluid, and paint solvents. Boys were more likely to have ever used
gasoline or nitrous oxide, while girls favored glue, shoe polish,
spray paints, correction fluid, and aerosol sprays.
“These findings suggest inhalant abuse and addiction in young
people are associated with a host of co-occurring problems that
may be influenced by family and other social factors,” says
NIDA Director Dr. Nora D. Volkow. “And, inhalant abuse may
be escalating. Data reported in NIDA’s Monitoring the Future
(MTF) Survey show that past-year use of inhalants rose 14 percent
from 2002 to 2003 — the only increase of any substance reported
by MTF between 2002 and 2003.”
Dr. Wu and colleagues examined the prevalence and characteristics
of inhalant use, abuse, and dependence among 36,859 adolescents
aged 12–17 who participated in the 2000 and 2001 National
Household Surveys on Drug Abuse (recently renamed the National Survey
on Drug Use & Health) by the Substance Abuse and Mental Health
Services Administration. Approximately 9 percent of the survey participants
— representing nearly 2 million adolescents nationwide —
reported having ever used inhalants in their lifetime. Among adolescents
who reported using inhalants during the past year, 11 percent met
the diagnostic criteria for abuse or dependence. There were no gender
differences in the prevalence of inhalant abuse or dependence.
Analysis of the accumulated data showed that:
- Adolescents who reported first use of inhalants at age 13–14
were six times more likely to be dependent on inhalants than those
who started using inhalants at age 15–17;
- Adolescents with a history of foster care placement were about
five times more likely to become dependent on inhalants than those
never placed away from home;
- Adolescents who were treated for mental health problems were more
than two times as likely to be dependent on inhalants;
- Adolescents who abused or were dependent on two other
drugs (such as cocaine/crack, marijuana/hashish, heroin, hallucinogens,
sedatives, tranquilizers, pain relievers, and stimulants) also
were likely to use inhalants; they were about four times more
likely to be diagnosed with inhalant abuse and about nine times
more likely to be diagnosed with inhalant dependence.
“Our study provides more evidence that early use of inhalants
may be a precursor for later drug abuse that grows to include abuse
of multiple illegal substances,” says Dr. Wu. “We found
that approximately 60 percent of the adolescents who reported using
inhalants during the past year also reporting the use of more than
one type of inhalant.”
Adds Dr. Volkow: “Children and adolescents who abuse inhalants
are at substantial risk of illness and death so it is important
for prevention programs to target children when they are young.
In addiction, factors such as early inhalant use, foster care placement,
and coexisting mental illnesses may help identify young people who
are especially vulnerable to severe drug abuse and mental health
problems.”
The National Institute on Drug Abuse is a component of the National
Institutes of Health, U.S. Department of Health and Human Services.
NIDA supports more than 85 percent of the world’s research
on the health aspects of drug abuse and addiction. The Institute
carries out a large variety of programs to ensure the rapid dissemination
of research information and its implementation in policy and practice.
