Psychology, Gr. 12: Drug Addiction Study Notes

Psychology
Drug Addiction

I.                   Drug Addiction                                                         pg. 116

-          Some drugs slow the nervous system causing numbness and sleepiness while others spur the nervous system into rapid action.
-          Addiction means that a person craves a substance, after he or she has consumed it several times, just to feel “normal”.
-          Drugs have a number of effects on consciousness and may distort perception, change mood, and/or cause people to hallucinate. Drugs that have the aforementioned effects are categorized as: Depressants, Stimulants, and Hallucinogens.

II.                Substance Abuse                                                       pg. 266-268

-          Abuse usually begins with experimentation in adolescence.
-          Reasons include curiosity, response to peer pressure, parental abuse, rebelliousness, escape from boredom, or pressure and looking for excitement/pleasure.
-          The number of drug abusers worldwide has been doubling annually since 1990.
-          People usually are oblivious that their consumption rates are considered abusive.
Five drinks or more in a row in one sitting are considered alcohol-abuse (binge drinking) there for linked to aggressive behavior and soon no longer suppress anxiety.
-          6 million people die each year from diseases linked to smoking such as lung cancer and heart attacks.
-          Cocaine for example, narrows blood vessels, thickens blood and quickens heart rate resulting in sudden deaths.
-          Marijuana contains more tar than cigarettes which is a main factor in lung cancer. Marijuana is also known to halt understanding and decrease alertness.
-          Intense cravings begin when the feeling has worn off. Drug abusers usually have to take more and more of the substance to reach the same effect they used to obtain with smaller doses, which eventually leads to addiction.

III.             Defensive Coping                                                     

-          Substance abuse, suicide and running away are ways considered to reduce the immediate effects of a stressor.
-          Referring to either to suppress stress is called defensive coping. It is usually the root to newer and bigger future problems.

IV.             Depressants                                                                pg. 117-118

-          Drugs that slow the activity of the nervous system.
-          Give people a sense of relaxation.
-          Include alcohol and narcotics.
A.     Alcohol
-          Only a few other drugs are used as widely as alcohol worldwide
-          Small amounts have relaxing effects and consuming enough can put the consumer to sleep.
-          Too much (over 5 drinks per sitting) is lethal on both short and long terms.
-          Intoxication: the medical term for drunkenness. Effects of intoxication or poisoning, slurs speech, blurs vision, impairs coordination and affects brain cells.
-          Alcohol makes people do things they do not do when sober because intoxication makes people less able to focus on judging the consequences of their behavior.
-          Withdrawal symptoms may include trembling and tension which often leads people to consume more to feel relaxed.
-          Alcohol is linked to fatal liver diseases, heart problems and cancer.
B.     Narcotics
-          Narcotics come from the Greek word “narke” or numb.
-          Narcotics are addictive depressants that are used to reduce pain and induce sleep (originally used medically).
-          Morphine, heroin, and codeine are narcotics derived from the opium poppy plant.
-          Morphine was introduced during the civil war to deaden the battle wound pains. Therefore, morphine addiction was known as “soldiers’ disease”.
-          Heroin was hailed as the “hero” that would cure addiction to morphine in the 1800s. It received its name due to the common belief that it made people heroic for being powerful at making its users feel pleased. However, heroin is known to plunge its consumers into depression. 
-          Narcotics impair judgements and memory, causes drowsiness and stupor (unconsciousness and insensibility)
-          High doses depress respiratory system which leads to unconsciousness, coma and sometimes death.
-          Narcotics are often consumed intravenously which increases the risk for transfer of blood diseases such as AIDS.
-          Withdrawal symptoms of narcotics include tremors, chills, rapid heartbeat, insomnia and bowel irritability.

V.                Stimulants                                                                  pg. 118-120
-          In contrast to depressants, stimulants increase the activity of the nervous system. It speeds up breathing and heart rate.
-          Stimulants include nicotine, amphetamines and cocaine.
A.     Nicotine:
-          The drug found in tobacco leaves.
-          One of the most commonly used stimulants. Legally smoked and/or chewed in most countries.
-          Spurs the release of the hormone adrenaline which increases heart rate.
-          As a stimulant, nicotine may make people feel more alert and attentive
-          Does no help improve the ability to perform complex tasks.
-          Reduces appetite and changes the rate at which the body changes food into energy thus the common fear of gaining weight upon quitting.
-          Through regular use, people can become addicted to nicotine
-          Evidence suggests that cigarette smokers experience symptoms such as insomnia, nervousness, drowsiness, loss of energy, headaches, cramps, heart problems, sweating, and tremors… however they usually link it to other causes.
-          Nonetheless, all people can successfully quit whenever they are truly motivated to.
-          Associated with serious health risks; the numbers of people who die from smoking-related disease each year is more than those who die from accidents, suicide, homicide, drug over dose and AIDS all combined.
B.     Amphetamines
-          A stimulant especially known for helping people stay awake and reducing appetite
-          First used by soldiers during WWII to help them remain awake and alert during the night
-          Market names: Tramadol, Speed, Uppers.
-          Produces feelings of pleasure in high doses.
-          Commonly consumed as pills, however injections are also common.
-          Large doses may result in a “many-days high”. Consumer could remain awake for as long as the prolonged high continues, however it eventually leads to “crashes”.
-          Crashes are episodes of long hours of restless deep sleep, depression, and may sometimes lead to suicide.
-          Symptoms of Amphetamines include but are not limited to: restlessness, insomnia, loss of appetite. It may also affect consciousness and cause frightening hallucinations.
-          May also cause users to have delusions, or false ideas that seem real.
C.     Cocaine

-          Raises blood pressure and decrease the supply of oxygen to the heart while speeding its beats’ rate which can lead to death
-          Introduced in the 1800s by Freud to cure depression and as a painkiller.
-          Freud published an article named the “Song of Praise” praising the effectiveness of the drug.
-          His excitement about cocaine’s healing powers soon faded by his awareness that the drug was dangerous and addictive.
-          Symptoms include restlessness, insomnia, trembling, headaches, delusions, nausea, hallucinations, and convulsions.
-          Crack is the most harmful form of cocaine because it is usually impure and therefore more dangerous.
-          The strain crack and other forms of cocaine put on the heart is fatal.

VI.             Hallucinogens                                                            pg. 120-121

-          A drug that produces hallucinations, a perception of an image or a sound that is non-existent.
-          Causes relaxation and sometimes pleasure. Reported to cause panic attacks in some users.
-          Include: Marijuana and LSD

A.     Marijuana:

-          Hash (Hashish) comes from the sticky roots of the plan and has stronger effects.
-          Impairs perception and coordination making operating machines (including driving cars) difficult.
-          Impairs memory and learning, causes anxiety and confusion.
-          Increases Heart Rate up to 140 beats per minute (normal rate 80), which is a particular threat to people with blood pressure problems.
-          100 years ago, it was used as commonly and for the same causes as aspirin is used today.
-          Distinct effect on consciousness especially in terms of time awareness; users usually feel that time passes slowly.
-          Visual hallucinations give smokers frights
-          Symptoms include confusion, loss of sense of self, and increased consciousness of body functions like Heart Beats.
B.     LSD/Acid

-          Some user experience lasting side effects which include memory loss, violent outburst, nightmares and feelings of panic.
-          Another distinct effect is experiencing “Flashbacks” to the hallucinations’ trance after a week, a month or even a year of the first experience.
-          Flashbacks stem from LSD-induced chemical changes in the brain after the first use.


VII.          Treatments

-          Treatments vary depending on the drug abused and the severity of addiction.
1.      Detoxification: The removal of the harmful substances from the body as a way of weaning addicts from the drug while restoring their health. Best method and most commonly used.
2.      Maintenance programs: sometimes used for narcotic’s addicts. Least effective method and very controversial because the users never actually become drug-free. Participants are given controlled and less doses of the drug or a less-addictive substitute.
3.      Counseling: conducted individually or in a group. Used for treating stimulant and depressant abuse.

4.      Support Groups: (in Egypt: Narcotics Anonymous) usually consists of people sharing common experiences, concerns and problems. They meet to provide one another with the emotional and moral support as well as encourage each other to live without drugs for the rest of their lives.
