Substance Abuse Trends and Consequences

Martin Arocena

Outline l.jpg


  • Introduction

  • Substance Consumption Patterns

  • Consequences

  • Need Assessment and Identification of Critical Needs

Strategic prevention framework l.jpg

Strategic Prevention Framework

  • DSHS applied for and received a grant to participate in SAMHSA’s Strategic Prevention Framework initiative.

  • Part of the requirements of the grant is that each funded state organize a state epidemiological workgroup (SEW).

State epi workgroup l.jpg

State Epi Workgroup

  • The purpose of the SEW is to:

    • Assess the status of the state with respect to substance abuse prevalence

    • Select consumption-related consequences and measure the state’s status on them

State epi workgroup5 l.jpg

State Epi Workgroup

  • Identify the state’s critical needs in terms of problem, population, and geographical location where problems are more severe.

  • Work with the Advisory Council to inform them and provide data as needed to help them make informed decisions.

State epi workgroup6 l.jpg

State Epi Workgroup

  • Texas’ epi workgroup consists of representatives from several state agencies, community organizations and academia that have information and access to consumption and consequences databases;

  • We received technical assistance from researchers from the Pacific Institute for Research and Evaluation and work closely with CSAP. They provide advice, leadership, and participate in the decision-making process.

State epi workgroup7 l.jpg

State Epi Workgroup

  • Drs. Cervantes and Rey from Behavioral Assessment Inc. as the contracted program evaluators are members of the group.

  • Liang Liu, the principal investigator of the Texas School Survey and I are the co-coordinators of the group.

  • The collaborators provided the data to us and we did the statistical analyses and reporting.

Age of Initiation

Binge drinking l.jpg

Binge Drinking

  • Binge Drinking

    • The 2004 Texas School Survey reports that approximately 23% of the students in grades 7 – 12 had 5 or more drinks on one occasion during the past year. The rate of binge drinking is decreasing from 27% in 2000 to 26% in 2002.

    • Based on YRBSS, 25.7% of high school students in Texas reported episodic heavy drinking (5 drinks or more in a row during the past 30 days).

Binge drinking19 l.jpg

Binge Drinking

Binge Drinking

Among the 18 to 25 years old group, about 58% were current drinkers and 40% were binge drinkers.

The current drinkers among the older group drops to about 50%. Binge drinkers drops to about 23%, and 5% heavy drinkers

Drinking and driving l.jpg

Drinking and Driving

  • About 14% of students in grades 9 through 12 admitted they had driven a car after having had a good bit to drink at least once in the past year, and 24% of the seniors said so.

  • 11% of students in grades 9 through 12 reported having driving when they were high from drugs and 18% of the seniors said so.

Adults trends l.jpg

Adults trends24 l.jpg

Adults Trends

  • The source for the Adult Trend information is: SAMHSA, Office of Applied Studies , National Household Survey on Drug Abuse 1999, 2000, and 2001

  • The information is for Texas.

  • Demographics:

    • Gender

    • Ethnicity

Gender differences l.jpg

Gender Differences

Inhalants l.jpg


  • About 7% of the youth had used inhalants in the past month. Due to its harmful effects on the brain and the relative easiness of getting the product the use of inhalants is considered a serious problem in the state

Cocaine l.jpg


  • The use of crack/cocaine in Texas has higher prevalence rates than in the other 50 states.

  • Approximately 7% of the 18 to 25 years old population reported using cocaine.

Methamphetamines l.jpg


  • The proportion of clients admitted to treatment that mentioned methamphetamines as their primary drug has increased from 5% to 10% in 2004.

  • Unlike the other drugs, more than one half (53%) of these clients were women.

At risk populations l.jpg

At Risk Populations

  • Use of alcohol, but not cigarettes, marijuana and cocaine, is higher among college students than among non-college youth of the same age.

  • There is a significant difference in the use of cocaine between border and non-border Hispanics.

Regional differences l.jpg

Regional Differences

  • Wallisch in the TCADA 2000 Adult Survey found that compared to the mean level for the state:

  • Region 6 had higher-than-average rates of alcohol use.

  • Region 7 had the highest rate of marijuana use in the state

  • Region 8 had the highest rate of cocaine use.

Consequences34 l.jpg


Substance abuse dependence l.jpg

Substance Abuse Dependence

  • The 2002-2003 NSDUH included questions designed to measure dependence and abuse of alcohol and drugs based on criteria specified in the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV).

Substance abuse dependence36 l.jpg

Substance Abuse Dependence

  • According to the national survey in Texas:

  • 12 to 17 group: 6 % = 123,088

  • 18 to 25 group: 17 % = 460,320

  • 26 and older: 6 % = 1,123,054

  • Texans were alcohol dependent or abusers.

Substance abuse dependence37 l.jpg

Substance Abuse Dependence

  • Alcohol is the most frequently mentioned primary drug reported by the Adult population admitted to publicly-funded treatment centers in Texas.

  • About 30 % of the clients reported this substance as their primary substance at admission.

Substance abuse dependence38 l.jpg

Substance Abuse Dependence

  • The national survey estimated the following percentages of residents in Texas who are dependent or abusers of any illicit drug:

  • 12 to 17 group: 5 % = 102,573

  • 18 to 25 group: 7 % = 189,543

  • 26 and older: 1.5 % = 280,764

Motor vehicle fatalities l.jpg

Motor Vehicle Fatalities

  • Texas was the state with the largest number of alcohol-related fatalities in the nation. Of the 42,643 MVF in the nation, 3,675 (1.58%) occurred in Texas.

  • Of the total 3,765 crashes in the state, 1,709 (47%) were alcohol-related. It is higher than the national average, 41%.

Motor vehicle fatalities40 l.jpg

Motor Vehicle Fatalities

  • In 2003, of the 5,011 drivers involved in a MVF, 1,469 (29.3%) were identified as having had some alcohol.

  • The age-group with the highest percentage of drunk drivers was the 21 – 29 years old group (38%)

Motor vehicle fatalities41 l.jpg

Violence l.jpg


  • As reported in the 10th Report to the U.S. Congress on Health and Alcohol:

    • The relationship between the offender’s drinking and the perpetration of violence has continued to show that the offender’s drinking is related to violence

Violence49 l.jpg


  • The amount of alcohol consumed tends to be larger in more serious offenses;

  • The connection between drinking and violence is stronger where the relationship between the perpetrator and victim is closer, and

  • Persons consuming large amounts of alcohol were at greater risk for violence than those consuming smaller amounts.

Crime related statistics l.jpg

Crime-Related Statistics

  • Violence rate includes aggravated assault, rape, and robbery. It is associated with alcohol abuse.

  • The UCR reports show that the Texas’ violence rate per population is higher than the national rate

Crime related statistics57 l.jpg

Crime-Related Statistics

  • Taking into consideration property crime rates per 1,000 population, it was found that among the top 20 counties, 6 were in the Rio Grande Valley (Cameron, Hidalgo, Kleberg, Webb, and Nueces Counties)

Mortality l.jpg


  • For this project, the selection of causes of death was based on the strength of the relationship between the illness and consumption of alcohol, drugs and tobacco.

  • Alcohol use is an intervening variable in homicides, suicides, and chronic liver disease.

Homicides l.jpg


  • Texas’ homicide rate, 6.9 per 100 K population is higher than the United States (5.9). The 18 to 29 age group had the highest homicide rate.

  • Although African-Americans have lower rates of substance abuse prevalence, they have higher rates of homicides.

  • 1,516 deaths were attributed to homicide.

Suicide l.jpg


  • Alcohol and other drugs are a contributing factor in suicides. State’s rate was 10.8 vs. 10.5 for the nation.

  • There were 2,354 suicides in Texas in 2,003. This is the leading cause of violent deaths each year.

Chronic liver disease l.jpg

Chronic Liver Disease

  • The state’s chronic liver disease prevalence rate (10.5 per 100 K pop) is higher than the national rate (9.5).

  • Over 90% of the deaths due to this disease happened to individuals in the older age groups.

  • Hispanics have a greater rate of deaths due to chronic liver disease (25.5) than other groups, 18.6 for Whites and 12.7 for African-American.

Tobacco related mortality l.jpg

Tobacco-related mortality

  • According to the CDC, tobacco is the leading cause of preventable deaths in the United States. Lung cancer, heart disease, and illnesses such as emphysema, bronchitis, and chronic airways obstruction are responsible for the largest number of smoking related deaths.

Tobacco related mortality63 l.jpg

Tobacco-related mortality

  • The majority of the individuals whose cause of death was lung cancer were in the 65 years old or older group.

  • This age disparity shows the long-term effect of cigarette smoking.

Summary l.jpg


  • Alcohol is the substance that is used by the greater percent of the population who use substances. Its use begins early, and the percent of users peaks in early adulthood. Its use continues to be high during adulthood, but the percent of users declines with age.

Summary65 l.jpg


  • Alcohol is strongly associated with the leading causes of death among the population under 20 years old: motor vehicle crashes, homicides and suicides.

    Although it can be classified as the main problem of the state, the use of other substances such as inhalants at early age, cocaine, and other drugs cannot be ignored.

Goals l.jpg


  • To reduce the percentage of adolescents who begin experimenting with alcohol, tobacco and other drugs by age 13.

  • To reduce the percentage of binge drinkers among underage and young adults (18 to 25)

  • To reduce the rates of intoxicated drivers involved in MVF especially among the 16 to 25 age group.
