ILLEGAL DRUGS The use of illegal drugs and the abuse of legal medicines can have serious, sometimes deadly, physical effects on the user. These effects can occur even the firest time the drug is used. (give example of Len Bias) Many drug users become addicted. Addiction is a physical or mental need for a drug or other substance. Some frequently abused addictive drugs will be discussed next. Stimulants Stimulants speed up the central nervous system. They cause an increase in respiratory and heart rates, high blood pressure, dilated pupils, and decreased appetite. In addition, users of stimulants may experience irritability, sweating, headaches, blurred vision, euphoria, dizziness or sleeplessness. Stimulants can be swallowed, smoked, inhaled, and injected. Two very powerful stimulants are amphetamines and cocaine. Amphetamines are used to treat narcolepsy, a disease that is an uncontrollable need to sleep, as well as in some cases of brain damage resulting from senility. Amphetamines also have been prescribed for weight control. Medical use of amphetamines has declined in recent years because of their limited effectiveness and potential for tolerance. Some people use amphetamines illegally to stay awake and alert. Others use them to feel high and euphoric, improve athletic performance, or lose weight. Some even try to offset the effects of depressants by taking amphetamines. Methamphetamine. Methamphetamine is an amphetamine that has been used medically in treating narcolepsy, Parkinson's disease, and obesity. In addition to the physical effects of amphetamines, methamphetamine may cause severe emotional and violent reactions. Methamphetamine is produced synthetically in "street" laboratories. This illegal form of methamphetamine is sometimes called crank, speed, or ice. Its availability has made its use very widespread. It can be smoked, injected, snorted or sniffed up the nostrils, or even swallowed. The effects of this drug are long-lasting. Seizures and death also can result. Cocaine Cocaine is a white powder that is an extract of the coca bush that grows in the mountainous regions of South America. About a century ago, cocaine was used as in ingredient in a well-known soft drink. In the 18th and 19th centuries, cocaine was used as a local anesthetic. In recent years, other medicines that are more effective and with fewer side effects have almost eliminated cocaine's use for medicinal purposes. Cocaine is a powerful, short-acting stimulant that affects the central nervous system. Its effects, which include increased heart rate, blood pressure and respiration, can last from 20 minutes to several hours. The feelings of confidence that come from cocaine use are often followed by a letdown. Regular use can lead to depression, edginess, and weight loss. Physiological dependence occurs because the user wants to avoid the letdown feeling. As cocaine use increases, so does the danger of paranoia, hallucinations, and psychological dependence. When cocaine is snorted, the drug is absorbed into the blood through the mucous membranes of the nose. Cocaine constricts the tiny blood vessels in this area, reducing the blood supply to the membranes that line the nose, causing them to become dry. Repeated cocaine use can cause tissue damage in the nose and even holes in the nasal septum, the wall dividing the two halves of the nose. Cocaine use can result in malnutrition and especially among those with cardiac problems, an increase in the risk of heart attack. Even in healthy individuals who are not heavy users of cocaine, the drug may disturb the electrical impulses of the heart and cause death. An additional risk of cocaine use is the possibility of being infected with HIV when injecting cocaine with a shared needle. Crack. Crack is a form of cocaine that can be smoked. Through illegal processing, cocaine can be converted into lumps or rocks. This process is called Freebasing. Freebasing is dangerous in itself because it involves the use of powerful solvents that can result in injury or death from an explosion or fire. Crack is highly addictive. Because it is smoked, its effects are felt within a few seconds. The physical effects of crack include dilated pupils, increased pulse rate, elevated blood pressure, insomnia, loss of appetite, hallucinations, paranoia, and seizures. Crack users may develop a sore throat, hoarseness and lung damage. Using crack can cause death by cardiac or respiratory failure. Depressants Depressants are drugs that slow down the body’s functions and reactions. They cause the heart rate and blood pressure to drop. Breathing and brain activity slow down. Two main types of depressants are barbiturates and tranquilizers. Dangers of using depressants include poor coordination, slurred speech, drowsiness, poor judgment, confusion and addiction. Narcotics Narcotics are drugs that act on the central and parasympathetic nervous systems to slow down body functions. At one time, the term "narcotics" referred only to those drugs that were made from the opium poppy and were called "opiates". Narcotics also are used as analgesics, or medicines used to relieve pain. Some medicines made from opium have valuable medical uses in relieving pain and suffering. For example, morphine is used to relieve pain, and codeine is used to stop severe coughing. Both cause drowsiness and can result in physiological dependence. Drugs made from opium can cause stupor or sleep and can result in coma or death. Narcotics can be natural or synthetic (made from laboratory chemicals). Narcotics are powerful addictive drugs capable of causing both physiological and psychological dependence. Withdrawal can result in loss of appetite, irritability, tremors, panic, cramps, nausea, chills and sweating. Heroin Heroin is a narcotic made from morphine and has no medical use. It is an illegal drug. Heroin is a strong central nervous system depressant. Its use slows breathing and pulse rate. Coma or death may occur with large doses. Tolerance develops very quickly with this drug. Heroin is usually injected and so the risk of hepatitis and HIV infection through the use of contaminated needles is ever present. Withdrawal from heroin is extremely painful and the chances of full recovery are not great. Treatment often involves methadone, a synthetic narcotic. Methadone blocks the craving for heroin. Its effects last 24 to 36 hours. Methadone also is addictive and must be closely monitored by qualified medical personnel. Hallucinogens Hallucinogens alter mood, thought and the senses, including sight, touch, smell, and hearing. Hallucinogens first became popular drugs during the 1960s. These drugs include synthetic products and naturallyoccurring substances. Hallucinogens have no medical use and are often unpredictable in their effects on the individual. Furthermore, users often mix these drugs with other drugs, and serious medical problems result. PCP Phencyclidine (PCP), also known as angel dust, is a powerful hallucinogen. It is prepared synthetically. PCP primarily affects the central nervous system. depending on the dosage, PCP can cause stimulation or depression. The unpredictable nature of PCP makes it a dangerous psychoactive drug. Users of this drug report severe loss of orientation with their surroundings and distortions in time, space, and feeling along with a highly dangerous inability to feel pain. Emotions are altered, sometimes bringing on very hostile and violent reactions. Most PCP-related deaths are caused by the strange, destructive behavior the drug produces in the user. Using PCP repeatedly makes it difficult to remember specific facts; it impairs speech, sometimes causing the user to stutter. Judgment and concentration are impaired long after the user has stopped taking the drug. Long-term users may experience anxiety, depression and violent behavior. Serious mental problems have also resulted from PCP, causing users to need psychiatric and sometimes, institutional care. The effects of PCP are widely unpredictable and vary from person to person. Once taken, PCP remains in the body long after the initial effect has worn off. A flashback may occur at a later time. A flashback is a reoccurrence of a drug effect without taking any more of the drug. These effects can include panic, confusion, suspicion and lack of control. Flashbacks also can repeat unpleasant physical and visual feelings. LSD Lysergic acid diethylamide (LSD) is probably the drug responsible for initiating an awareness of hallucinogens in American society. LSD severely distorts perception, causing users of the drug to attempt to do impossible feats that often end in disaster. Use of LSD and the resulting tragedies--deaths from a false sense of security or hallucinations--received much publicity. During the 1960s and 1970s, LSD was tried in different types of therapy. It proved to be unpredictable and unreliable and therefore no longer has medical use. Marijuana Marijuana is the common name for the Indian hemp plant, “ Cannabis”. The leaves and flowers of this plant are smoked, chewed, or eaten for their intoxicating effects. Because of potentially dangerous effects, marijuana is an illegal drug under the state and federal laws. The chemical in marijuana responsible for its psychoactive effect is delta-9-tetrahydrocannabinol (THC). Scientists test the strength of a sample of marijuana by measuring how much THC is contains. When THC enters the blood, some is stored in fatty tissue. Because of this, it takes at least 30 days for the body to excrete it. The highest concentration of fat cells in the body is in brain cells, liver, lungs, kidneys and reproductive organs. Mariujuna acts like a hallucinogen, although it also has effects similar to stimulants and depressants. It lowers body temperature, but increases the heart rate and blood pressure, and has a stimulating effect on the appetite. Marijuana effects sight, touch and sound. Perception of time is also affected. Marijuana users often develop psychological dependence on the drug, wanting the euphoric feelings that they experience. Hashish is the dark brown resin collected from the tops of the Cannabis plant. Hash is stronger than marijuana because it contains more THC, so when used, its effects are more pronounced. Like marijuana, hash is an illegal drug. Inhalants Inhalants are substances that give off fumes that are sniffed and inhaled to give a hallucinogenic effect. Most inhalants are products that were never designed to be taken into the human body, such as gasoline, glue and aerosols. Inhalants are extremely dangerous. In fact, many are labeled poisonous. Most inhalants depress the CNS and cause effects similar to those of alcohol. Immediate effects include nausea, sneezing, coughing, nosebleeds, fatigue, lack of coordination and loss of appetite. A person who regularly sniffs an inhalant has trouble with balance and finds it hard to talk. Judgment is impaired. Heavy use of inhalants can result in fatigue, liver and kidney damage, changes in bone marrow, and permanent brain damage. High concentrations can cause suffocation. Accidental death can occur. Designer Drugs Designer drugs are synthetic substances chemically similar to drugs listed in the controlled substances schedule. Designer drugs are made by street "chemists" who alter the molecular structures of drugs by using more common chemicals to make them. This is done in hopes of avoiding the highly technical chemical definitions of illegal drugs. These drugs are also called "analogs" because they are substantially similar in their chemical makeup and produce similar effects to the drugs listed in the controlled substances schedules. MDMA, Adam and Ecstasy (X-TC) are all slang names for a designer drug similar to methamphetamine. Ecstasy acts as both a stimulant and hallucinogen. It causes feeling of euphoria and results in long-term damage to brain cells. Side effects also include increased blood pressure and heart rate, confusion, and severe anxiety. Anabolic Steroids Anabolic steroids are synthetic derivatives of the male hormone testosterone. When used as a medicine, steroids help build muscles in individuals who suffer from chronic diseases. Anabolic steroids also have been used to treat bone diseases, burns, and hormonal imbalances, and to protect blood cells during treatment for cancer. Side effects of steroid use include high blood pressure, acne, increased risk of liver damage, heart disease and stroke. Anabolic steroids are used illegally by some athletes to enhance performance. Because steroids help the body synthesize protein for tissue development and muscular growth, athletes who use them recover more quickly from injuries after practice or a game. Steroid use also increases aggressiveness and strength. Because of their dangerous nature and several serious side effects, steroids are illegal unless specifically prescribed by a physician.
