TOBACCO - THE FACTS
- Nicotine is a highly addictive nerve stimulant.
- There are 4,000 chemicals and nearly 50 cancer-causing substances in cigarette smoke.
- 85% - 90% of those who smoke as adults begin by age 19.
- Smoking is responsible for one out of three deaths in the United States.
- A teen who smokes cigarettes daily is 20 times more likely to be a marijuana user and 13 times more likely to be a daily user of other drugs than a teen who does not smoke.
- 80% of adolescent cigarette smokers are also users of marijuana.
- Nonsmokers exposed to environmental tobacco smoke are at an increased risk for the same problems as smokers.
- Teenagers are prime targets of tobacco advertisers, and each year, one million teenagers will start smoking.
ALCOHOL - THE FACTS
- Alcohol is called a drug because its main ingredient, ethanol, in higher doses, acts as a general anesthetic (like ether).
- Alcohol is a depressant, and as such, it slows the brain and central nervous system. When large quantities are ingested, it is possible for the brain to shut down partially or completely, resulting in a coma, respiratory failure, or possibly death.
- More than a third of America’s 3.3 million alcoholics are under the legal drinking age.
- 30% of high school seniors get drunk once a week and 6% are daily drinkers.
- Adolescents can become alcoholics in 3-24 months versus 10-15 years for adults.
- In the adolescent, very low blood alcohol levels can produce irrational judgment and reduce self control.
- Incomplete muscle formation, bone growth, and juvenile fat deposits decrease the teen’s resistance to alcohol toxicity.
MARIJUANA - THE FACTS
- Marijuana is now 2-10 times stronger than it was 10 years ago. Hybrid forms of marijuana like sinsemilla (seedless) contain much more of the active ingredient, tetrahydrocannabinol (THC), rendering it even more potent. Potency also varies from climate to climate and ounce to ounce.
- Cannabis inhibits short term memory, slows reaction time, and impairs visual tracking. Frequent use is also linked to cognitive impairment (an inability to understand concepts).
- Frequent users’ rate of social development may slow. A pattern of denying problems and irresponsibility in facing obligations can develop.
- Some frequent users find it hard to stay motivated, and develop a lack of initiative and concern about the future. Often a pattern of superficial relationships develops with people who expect or demand little of the user.
- Cannabis is stored in the brain, testes, ovaries, and other fatty organs for up to a month or more and is detectable by urine tests. Detection periods span 4-6 days in acute users and 20-50 days in chronic users.
- Marijuana is up to 200 times more likely to cause cancer than tobacco smoke, and frequent use is linked to an increase of lung cancer, bronchitis, and emphysema.
- Marijuana depresses the immune system, therefore it is more difficult for the user to fight off colds, flus, or other viruses.
- Cannabis speeds a user’s heart by as much as 50%, increasing risks for anyone with heart disease.
- Marijuana inhibits nausea and allows a person to consume large quantities of alcohol without getting sick. As a consequence, death due to alcohol overdoses has escalated among teenagers.
METHAMPHETAMINES - THE FACTS
Methamphetamine is an addictive stimulant drug that strongly activates certain systems in the brain. Methamphetamine is chemically related to amphetamine, but the central nervous system effects of methamphetamine are greater. Both drugs have some limited therapeutic uses, primarily in the treatment of obesity.
Methamphetamine is made in illegal laboratories and has a high potential for abuse and addiction. Street methamphetamine is referred to by many names, such as "speed," "meth," and "chalk." Methamphetamine hydrochloride, clear chunky crystals resembling ice, which can be inhaled by smoking, is referred to as "ice," "crystal," "glass," and "tina."
Methamphetamine releases high levels of the neurotransmitter dopamine, which stimulates brain cells, enhancing mood and body movement. It also appears to have a neurotoxic effect, damaging brain cells that contain dopamine as well as serotonin, another neurotransmitter. Over time, methamphetamine appears to cause reduced levels of dopamine, which can result in symptoms like those of Parkinson’s disease, a severe movement disorder.
Methamphetamine is taken orally or intranasally (snorting the powder), by intravenous injection, and by smoking. Immediately after smoking or intravenous injection, the methamphetamine user experiences an intense sensation, called a “rush” or “flash,” that lasts only a few minutes and is described as extremely pleasurable. Oral or intranasal use produces euphoria—a high, but not a rush. Users may become addicted quickly, and use it with increasing frequency and in increasing doses.
Animal research going back more than 20 years shows that high doses of methamphetamine damage neuron cell endings. Dopamine- and serotonin-containing neurons do not die after methamphetamine use, but their nerve endings (“terminals”) are cut back, and regrowth appears to be limited.
The central nervous system (CNS) actions that result from taking even small amounts of methamphetamine include increased wakefulness, increased physical activity, decreased appetite, increased respiration, hyperthermia, and euphoria. Other CNS effects include irritability, insomnia, confusion, tremors, convulsions, anxiety, paranoia, and aggressiveness. Hyperthermia and convulsions can result in death.
Methamphetamine causes increased heart rate and blood pressure and can cause irreversible damage to blood vessels in the brain, producing strokes. Other effects of methamphetamine include respiratory problems, irregular heartbeat, and extreme anorexia. Its use can result in cardiovascular collapse and death.
LSD - THE FACTS
- LSD is one of the most potent chemicals known to affect the human brain. It appears to work by profound disruption of brain neurotransmitters.
- A white, odorless crystalline material, LSD is diluted and sprayed on sheets of blotter paper for oral ingestion. This paper, known as “Blotter Acid,” frequently has designs printed on it.
- The “high” lasts for six to 14 hours.
- Mental effects include changes in perception, thinking, emotion, arousal, and self-image.
- Even a small dose of LSD can unpredictably cause toxic delirium or “bad trips.”
- Terrifying illusions and hallucinations may precipitate panic attacks or reckless behaviors.
- 16% of student LSD users reported the use of other illegal drugs, such as PCP, Ecstasy, Speed, Ice, or Heroin.
LSD is experiencing a comeback in the 90's among white, middle-class high school and college students. LSD is the third most frequently taken drug, after alcohol and marijuana, according to one study of adolescent users. In 1995, there were more LSD-related arrests, emergency room visits by adolescents, and violent behavior, including suicide, homicide, and accidental death than had previously been recorded.
Chronic aftereffects of LSD use include: chronic or intermittent psychotic states, recurrent depression, and Post-Hallucinogenic Perceptual Disorder (PHPD), e.g., flashbacks characterized by periodic hallucinatory imagery, months or years later.
LSD use is increasing sharply in the youth across the country. It is inexpensive, very available, easy to conceal, easy to administer, and use is difficult to detect through observation or testing.
INHALANTS - THE FACTS
- Inhalant abuse is always dangerous and can be deadly.
- Risks include suffocation, heart failure, and organ damage.
- Inhalants are intoxicating in much the same way as alcoholic beverages. Abusers often act confused and giddy, and may appear clumsy and accident-prone. Odd and unpredictable behavior is also characteristic of inhalants.
- A user’s lack of judgment and diminished physical coordination can pose significant danger.
- Headaches, upset stomach, vomiting, diarrhea, and poor reflexes are among the side effects produced by inhalants.
- Users may become dependent and undergo painful withdrawal symptoms when they stop using.
- Many users of inhalants move onto other drugs, particularly alcohol, marijuana, and barbiturates.
Because they cost little and can be obtained easily, inhalants have become the drug of choice for many adolescents. Inhalants include gasoline, butane, toluene products (glues, acrylic paints, paint thinners), halogenated hydrocarbons (freon, solvents, spot removers, typewriter correction fluid), nitrous oxide (dental anesthetics, whipped cream propellants, automotive power boosters), and alkyl mitrites/nitrates (called “poppers” or “snappers”), which include room deodorants and liquid incense. Currently, the most popular inhalants are nitrous oxide (called “Nitty”), propane, and air fresheners.
OTHER DRUGS - THE FACTS
- Stimulants - These drugs, sometimes called uppers, activate a pleasure center in the brain. Stimulants include caffeine pills; amphetamines such as Benzedine and Dexedrine; Ritalin (called “Ritz”); and cocaine. Cocaine comes in powder or rock form and can be referred to as “Rock,” “Crack,” “Blow,” or “Linen.” These drugs speed pulse rates and increase blood pressure, and they may contribute to insomnia and appetite suppression. Some stimulants, such as No-Doze, weight-loss pills, stay-alert pills, are also available over-the-counter.
- Hallucinogens - Drugs such as PCP, MDA, DMT, STP, mescaline, peyote, and psilocybin relax inhibitions and can cause hallucinations that affect a person’s thinking, awareness, and sensations, as well as dramatically increases blood pressure and produce irregular heartbeats. Teens use the term “tripping” to describe the high obtained from these types of drugs. The most popular hallucinogens used today, aside from LSD, are mushrooms (called “shrooms”), Ecstacy, Ketamine (called “Special K”), and motion sickness pills.
- Anabolic Steroids - Increasingly popular among teenagers, anabolic steroids (also called ‘roids, the juice, pump, or hype) build body muscle mass and enhance athletic performance. Some athletes start taking steroids because they think they must do so in order to win. Other teens use them to grow bigger and stronger at any cost. There are many side effects both physical and emotional. Considering the potential risks, steroids should be considered serious drugs of abuse even though they aren’t used to get high.
- Narcotics - The abuse of opiates has occurred for years. Injectable heroin has been perhaps the best known opiate to be abused, but people have also abused opium, morphine, methadone, codeine, Dilaudid, Percodan, and Darvon. Currently, opium (called “Tar”) and brown heroin (called “Brown”) are popular in this area.
