Substance Abuse Overview
People abuse substances such as alcohol, tobacco, and other drugs for varied and complicated reasons, but it is clear that our society pays a significant cost. The toll for this abuse can be seen in our hospitals and emergency departments
both through direct damage to health by substance abuse and its link to physical trauma. Jails and prisons tally daily the strong connection between crime and drug dependence and abuse. Although use of some drugs such as cocaine has declined
in recent years, use of other drugs such as heroin and "club drugs" has increased.
- Finding effective treatment for and prevention of substance abuse has been difficult. Through research, we now have a better understanding of this behavior. Studies have made it clear that drug education and prevention aimed at children and adolescents offers the best chance to curb abuse nationally.
- The 2010 National Household Survey on Drug Abuse estimated the number of users of illicit drugs in the United States to be over 22 million. Other statistics from the survey include that nearly 7% of Americans over 12 years
of age are binge drinkers and almost 70 million of Americans smoke cigarettes. Other research shows that about 22 million people over 12 years
of age in the United States have abused inhalants and three-quarters of a million use inhalants for the first time each year.
Abused substances produce some form of intoxication that alters judgment, perception, attention, or physical control.
Many substances can bring on withdrawal effects caused by cessation or reduction in the amount of the substance used. Withdrawal can range from mild anxiety to seizures and hallucinations. Drug overdose may also cause death.
Nearly all these drugs also can produce a phenomenon known as tolerance, in which one must use a larger amount of the drug to produce the same level of intoxication. Commonly abused drugs include
- Inhalants: This group of substances includes solvents that emit vapors, causing intoxication when breathed in (inhaled). Individuals who abuse inhalants intentionally breathe in the vapors, either directly from a container, from a bag in which such a substance is in, or from a rag soaked with the substance and then placed over the mouth or nose. Inhalant intoxication happens quickly and doesn't last long.
- Abuse of inhalants is also called "huffing." Approximately 58% of inhalant users report first using it by the end of ninth grade. Teens who started using inhalants before 15 years
of age were up to six times more likely as those who had started later to develop dependence on these substances.
- Symptoms of inhalant intoxication are very similar to those seen with intoxication with alcohol, including dizziness, clumsiness, slurred speech, elation, tiredness, slowed reflexes, thinking and movement, shaking, blurred vision, stupor or coma, and/or weakness. It can also result in chemical and temperature burns, as well as withdrawal symptoms, chronic mental illness, and even sudden death.
- Long-term damage associated with inhalant use includes brain and nerve damage as well as heart, liver, or kidney failure
- Tobacco: People cite many reasons for using tobacco, including pleasure, improved performance and vigilance, relief of depression, curbing hunger, and weight control.
- The primary addicting substance in cigarettes is nicotine. But cigarette smoke contains thousands of other chemicals that also damage health
both to the smoker and to those around them. Hazards include heart disease, lung cancer and emphysema, peptic ulcer disease, and stroke. Withdrawal symptoms
of smoking include anxiety, hunger, sleep disturbances, and depression.
- Smoking is responsible for nearly a half million deaths each year. Tobacco use costs the nation an estimated $100 billion a year, mainly in direct and indirect health care costs.
- Alcohol: Although many people have a drink as a "pick me up," alcohol actually depresses the brain. Alcohol lessens your inhibitions, slurs speech, and decreases muscle control and coordination, and
prolonged use may lead to alcoholism.
- Withdrawal from alcohol can cause anxiety, irregular heartbeat, tremor, seizures, and hallucinations. In its severest form, withdrawal combined with malnutrition can lead to a life-threatening condition called delirium tremens (DTs). Alcohol
abuse is the most common cause of liver failure in the U.S. The drug can cause heart enlargement and cancer of the esophagus, pancreas, and stomach.
- In addition to its direct health effects, officials associate alcohol abuse with
nearly half of all fatal motor-vehicle accidents. In 1992, the total economic cost of alcohol abuse was estimated at $150 billion.
