Drugs and Alcohol Abuse Questions in English

(B) $Heroin$ is an opioid that acts as a depressant,slowing down body functions. In contrast,$cocaine$ is a stimulant derived from the plant $Erythroxylum$ $coca$. It interferes with the transport of the neurotransmitter dopamine. $Cocaine$ has a potent stimulating action on the central nervous system,producing a sense of euphoria and increased energy.

(A) Tobacco contains an alkaloid called nicotine.
Nicotine stimulates the adrenal glands to release adrenaline (epinephrine).
This release of adrenaline increases blood pressure and heart rate,which is why tobacco consumption is harmful to the cardiovascular system.

(B) Smoking is a major health hazard that leads to several severe diseases.
- $1$. Lung cancer: Tobacco smoke contains carcinogens that damage lung tissue.
- $2$. Bronchitis: Chronic inflammation of the bronchi due to smoke inhalation.
- $3$. Gastric ulcer: Smoking increases acid secretion and reduces the protective mucosal lining of the stomach.
- $4$. Emphysema: $A$ condition where the alveoli in the lungs are damaged,leading to shortness of breath.
Therefore,all these conditions are associated with smoking.

(A) The correct answer is $A$. $Cannabis$ $sativa$ (hemp plant) is well-known for its hallucinogenic properties due to the presence of cannabinoids like $THC$ (tetrahydrocannabinol).
$Atropa$ $belladonna$ is a poisonous plant containing tropane alkaloids.
$Papaver$ $somniferum$ (opium poppy) is the source of opiates like morphine and codeine,which are sedatives/painkillers,not primarily hallucinogens.
$Heroin$ is a semi-synthetic opioid derived from morphine,not a plant.

(A) $1$. $LSD$ (Lysergic acid diethylamide) is a powerful hallucinogenic drug that alters perception,mood,and thought processes. It is not used as a medicine for treating mental illnesses like depression or insomnia.
$2$. Amphetamines are central nervous system stimulants sometimes used in specific clinical conditions,though they are not primary treatments for depression.
$3$. Barbiturates are central nervous system depressants that have been historically used as sedatives and hypnotics to treat insomnia.
$4$. Glycosides (like cardiac glycosides) are used for heart conditions and are not psychiatric medications.
$5$. Among the given options,$LSD$ is a hallucinogen with no therapeutic use for depression or insomnia,making it the correct answer in the context of drugs that are not helpful for these conditions.

(C) Withdrawal syndrome refers to a set of unpleasant symptoms that occur when a person who is dependent on a substance (such as drugs or alcohol) suddenly stops or significantly reduces their intake.
Because the body has adapted to the presence of the substance,the abrupt discontinuation leads to physiological and psychological distress,which is known as withdrawal syndrome.

(C) Cocaine is a stimulant drug obtained from the plant $Erythroxylum$ $coca$. It interferes with the transport of the neurotransmitter dopamine by blocking the dopamine transporter,which leads to an accumulation of dopamine in the synaptic cleft,causing a sense of euphoria and increased energy.

(B) Heroin,commonly known as smack,is chemically diacetylmorphine.
It is a white,odorless,bitter,crystalline compound.
This is obtained by the acetylation of morphine,which is extracted from the latex of the poppy plant,$Papaver$ $somniferum$.

(C) Opiates are drugs that are derived from the opium poppy $(Papaver \text{ somniferum})$.
Heroin, also known as diacetylmorphine, is a semi-synthetic opioid derived from morphine, which is extracted from the opium poppy.
Cannabis and Charas are cannabinoids, while Nicotine is a stimulant found in tobacco.
Therefore, Heroin is the correct answer.

(B) Nicotine is a chemical compound found in tobacco that acts as a stimulant in mammals. It functions by binding to and activating nicotinic acetylcholine receptors $(nAChRs)$ in the central and peripheral nervous systems. Because its structure allows it to bind to these receptors,it mimics the action of the neurotransmitter $Acetylcholine$,leading to increased alertness,heart rate,and blood pressure. Therefore,the correct option is $B$.

(B) Opiates are drugs that are derived from the opium poppy plant ($Papaver$ $somniferum$).
$Morphine$ is a potent analgesic and a classic example of an opiate narcotic.
$Barbiturates$ are depressants but not opiates.
$Amphetamines$ are stimulants.
$LSD$ ($Lysergic$ $acid$ $diethylamide$) is a hallucinogen.
Therefore, the correct option is $B$.

(A) $LSD$ stands for Lysergic Acid Diethylamide. It is a well-known psychoactive drug that belongs to the class of hallucinogens. Hallucinogens are substances that alter a person's thoughts, feelings, and awareness of their surroundings, often causing them to see or hear things that are not actually there.

(A) Reserpine is a drug derived from the plant $Rauwolfia$ $\text{serpentina}$, which acts as a tranquilizer to reduce blood pressure and treat mental disorders.
Cocaine is a stimulant obtained from $Erythroxylum$ $\text{coca}$, not an opiate.
Morphine is an analgesic (painkiller) obtained from the latex of the poppy plant, not a hallucinogen.
Bhang is a preparation from the leaves of $Cannabis$ $\text{sativa}$ and acts as a hallucinogen, not an analgesic.
Therefore, the correct pair is $A$.

(A) Valium (a type of benzodiazepine) acts as a central nervous system depressant. It enhances the effect of the neurotransmitter $GABA$ in the brain,which leads to a calming effect,relaxation,and drowsiness. Morphine is an opioid analgesic,Hashish is a cannabinoid (hallucinogen),and Amphetamines are stimulants.

(A) Psychotropic drugs are chemical substances that affect the brain and alter mood,perception,and behavior.
$A$. Hashish is a cannabinoid that significantly alters sensory perception and induces hallucinations.
$B$. Opium is a depressant,not a stimulant; it slows down the central nervous system.
$C$. Morphine is a potent analgesic (painkiller) derived from opium,primarily used for pain management,not typically associated with causing delusions.
$D$. Barbiturates are synthetic drugs that act as central nervous system depressants (sedatives/hypnotics),promoting relaxation and sleep,often used to treat anxiety or insomnia.

(B) $1$. Morphine is a potent opioid analgesic derived from the poppy plant ($Papaver$ $somniferum$).
$2$. It is widely used in clinical settings as a painkiller for patients who have undergone surgery or are suffering from severe pain.
$3$. Sedatives (like barbiturates) are not used to force truth-telling; this is a common misconception.
$4$. Tobacco contains nicotine,which stimulates the adrenal gland to release adrenaline and nor-adrenaline,leading to an increase in blood pressure and heart rate,not a decrease.
$5$. Cocaine is a stimulant that acts on the central nervous system and is not used for post-operative recovery.

(B) Liver cirrhosis is a condition in which the liver is scarred and permanently damaged. Chronic alcohol consumption is a leading cause of liver cirrhosis. When alcohol is metabolized in the liver,it produces toxic substances that cause inflammation and damage to liver cells (hepatocytes) over time,leading to the formation of fibrous scar tissue.

(A) The plant shown in the image is $Datura$ (commonly known as Jimsonweed or Thorn apple).
$Datura$ species are well-known for their hallucinogenic properties.
They contain alkaloids such as scopolamine,hyoscyamine,and atropine,which act on the central nervous system to produce hallucinations.
Therefore,the chemical obtained from this plant is a hallucinogen.

(B) The drug commonly known as "Smack" is $Heroin$, which is chemically $Diacetylmorphine$.
It is a white, odorless, bitter crystalline compound.
It is obtained by the acetylation of $Morphine$, which is extracted from the $Latex$ of the poppy plant, $Papaver \text{ } somniferum$.

(B) Heroin,also known as diacetylmorphine,is a semi-synthetic opioid drug.
It is chemically synthesized from morphine,which is extracted from the latex of the poppy plant,$Papaver$ $somniferum$.
The process involves the acetylation of morphine,where two acetyl groups are added to the morphine molecule.
This chemical modification makes heroin more lipid-soluble than morphine,allowing it to cross the blood-brain barrier more rapidly.

(D) Amphetamines are stimulants that increase the activity of the $CNS$.
Lysergic acid diethylamide $(LSD)$ is a well-known hallucinogen.
Heroin is a depressant (opioid) that slows down body functions.
Benzodiazepines are sedatives or tranquilizers used for anxiety and sleep disorders,not primarily as pain killers (analgesics). Therefore,the pair 'Benzodiazepine $-$ pain killer' is incorrect as they are not classified as analgesics.

(D) Opium is a narcotic substance obtained from the dried latex of the immature seed pods of the opium poppy plant,$Papaver \text{ } somniferum$.
It contains various alkaloids,with morphine being the most abundant,accounting for approximately $10\%-16\%$ of the total alkaloid content.
Opium and its derivatives are known for their potent analgesic properties but carry significant risks of addiction and harmful side effects,including respiratory depression,lung edema,coma,and potential cardiac or respiratory failure.

(D) The correct match is $D$.
$1$. $Bhang$ is a cannabinoid,not an analgesic.
$2$. $Cocaine$ is a stimulant,not an opiate narcotic.
$3$. $Morphine$ is an opiate narcotic,not a hallucinogen.
$4$. $Barbiturates$ are drugs that act as central nervous system depressants and are commonly used as tranquilizers or sedatives.

(D) $LSD$ (Lysergic acid diethylamide) is a powerful hallucinogen,not an analgesic. Marijuana (cannabinoids) acts on cannabinoid receptors in the brain and is primarily used for its psychoactive effects,though it has some medicinal applications for pain management in specific chronic conditions,it is not classified as a standard clinical analgesic. The assertion is incorrect because they are not primarily used as analgesics. The reason is also incorrect as they are hallucinogens or psychoactive substances that alter brain function rather than simply suppressing it.

(D) The Assertion is incorrect because a 'Dope test' is specifically used to detect the presence of performance-enhancing drugs in athletes,not to measure blood alcohol levels. Breathalyzers are used for alcohol testing.
The Reason is also incorrect because a person under the influence of alcohol typically exhibits symptoms like loss of inhibition,increased talkativeness,and reduced coordination,rather than feeling tense or less talkative.
Therefore,both the Assertion and the Reason are incorrect.

(D) $Cannabis \text{ } sativa$ (Hemp) is an annual herb belonging to the family $Cannabaceae$. It is primarily known as a source of fiber.
$Cannabis \text{ } sativa$ is not an antidepressant. Antidepressants are psychiatric medications used to treat mood disorders like major depression.
Hashish and Marijuana are indeed drugs derived from this plant. Marijuana is prepared from the dried flowers and leaves, while Hashish is prepared from the resinous extract.
Both substances are hallucinogens that affect the central nervous system and can cause acute panic and anxiety reactions, rather than acting as antidepressants.
Therefore, the Assertion is incorrect, but the Reason is correct.

(C) Coca alkaloid, commonly known as cocaine, is obtained from the plant $Erythroxylum \, coca$, a plant native to South America.
It interferes with the transport of the neurotransmitter dopamine.
$Papaver \, somniferum$ is the source of opium/morphine.
$Atropa \, belladonna$ and $Datura$ are known for their hallucinogenic properties.

(N/A) Alcohol and drugs have several adverse effects on the individual,their family,and society.
Effects of alcohol:
Effects on the individual: Alcohol negatively impacts the body. Excess consumption causes damage to the liver (e.g.,cirrhosis) and the nervous system. Symptoms include depression,fatigue,aggression,and loss of weight and appetite. Extreme consumption may lead to heart failure,coma,and death. Pregnant women are advised to avoid alcohol as it inhibits the normal growth of the fetus.
Effects on the family: Excessive alcohol consumption by a family member leads to domestic problems such as quarrels,frustration,and financial insecurity.
Effects on the society: It leads to rash behavior,malicious mischief,violence,a deteriorating social network,and loss of interest in social activities.
Effects of drugs:
Effects on the individual: Drugs adversely affect the central nervous system,leading to the malfunctioning of organs like the kidneys and liver. The risk of $HIV$ and Hepatitis-$B$ infection is high due to the sharing of needles. Long-term side effects include increased aggressiveness,mood swings,and depression.
Effects on the family and society: $A$ person addicted to drugs becomes frustrated,irritated,and anti-social,causing distress to family members and creating a burden on society.

(N/A) Yes,friends can significantly influence an individual to experiment with or consume drugs and alcohol. To protect oneself from such negative peer pressure,one can adopt the following measures:
$1$. Strengthen your willpower: Develop a strong resolve to stay away from alcohol and drugs. Never experiment with these substances out of curiosity or for temporary fun.
$2$. Avoid negative peer groups: Consciously distance yourself from friends or social circles that encourage or engage in drug and alcohol abuse.
$3$. Seek support: Maintain open communication with parents and trusted peers. Do not hesitate to share your concerns with them.
$4$. Education and engagement: Gain proper knowledge about the harmful effects of drug abuse. Channel your energy into productive extra-curricular activities like sports,arts,or hobbies.
$5$. Professional help: If you notice signs of depression,anxiety,or frustration,seek immediate professional guidance from psychologists,psychiatrists,or counselors to address the root cause before it leads to substance abuse.

(D) The consumption of alcohol and drugs is associated with a temporary feeling of well-being and euphoria,which acts as a positive reinforcement for the brain.
Repeated intake of these substances leads to the development of tolerance,where the body's receptors become less sensitive,requiring higher doses to achieve the same effect.
Furthermore,the body develops a physical and psychological dependence,leading to withdrawal symptoms when the substance is discontinued,making it extremely difficult to quit the habit.

(N/A) Many factors are responsible for motivating youngsters towards alcohol or drugs. Curiosity,the need for adventure and excitement,and experimentation are the initial causes of motivation.
Some youngsters start consuming drugs and alcohol to overcome negative emotions (such as stress,pressure,depression,and frustration) or to excel in various fields.
Several mediums like television,the internet,newspapers,and movies are also responsible for promoting the idea of alcohol to the younger generation.
Amongst these factors,reasons such as unstable and unsupportive family structures and peer pressure can also lead an individual to become dependent on drugs and alcohol.
Preventive measures against the addiction to alcohol and drugs:
$1$. Parents should motivate their children and try to increase their willpower.
$2$. Parents should educate their children about the ill-effects of alcohol and drugs. They should provide them with proper knowledge and counseling regarding the consequences of addiction.
$3$. It is the responsibility of the parents to discourage a child from experimenting with alcohol or drugs. Youngsters should be kept away from the company of friends who consume these substances.
$4$. Children should be encouraged to devote their energy to other extracurricular and recreational activities.
$5$. Proper professional and medical help should be provided to a child if sudden symptoms of depression and frustration are observed.

(N/A) Statistical surveys indicate that the consumption of drugs and alcohol is prevalent among the youth,leading to various harmful effects. It is essential to provide proper education and counseling to protect the youth from such dangerous behaviors,enabling them to adopt a healthy lifestyle.
Commonly used addictive substances include opioids,cannabinoids,and cocaine. Most of these are derived from flowering plants and some fungi.
$Opioids$ are drugs that bind to specific opioid receptors present in our central nervous system and gastrointestinal tract. Heroin,commonly known as smack,is chemically $diacetylmorphine$. It is a white,odorless,bitter,crystalline compound. It is obtained by the acetylation of morphine,which is extracted from the latex of the poppy plant,$Papaver$ $somniferum$.
Heroin is generally taken by snorting or injection. It acts as a depressant and slows down body functions.

(N/A) Adolescence is a period and a process during which a child becomes mature in terms of attitudes and beliefs for effective participation in society. The period between $12$ and $18$ years of age is called adolescence. In other words, adolescence is a bridge linking childhood and adulthood. Adolescence is accompanied by several biological and behavioral changes. Thus, it is a very vulnerable phase of mental and psychological development of an individual.
Curiosity, need for adventure and excitement, and experimentation are common causes that motivate youngsters towards drug and alcohol use. $A$ child's natural curiosity motivates them to experiment.
Perceiving the effects of drugs and alcohol as beneficial makes the problem more complex. Later, adolescents start using them to escape from problems. Some adolescents start using drugs and alcohol under stress and pressure due to poor performance in studies or examinations. There is also a misconception among youth that smoking, or using drugs and alcohol, is a symbol of being '$cool$' or '$progressive$'.
These habits are the primary reasons for their consumption. Media such as television, movies, newspapers, and the internet also promote these habits. Other reasons for drug and alcohol abuse in adolescents include unstable family structures, lack of support, and peer pressure.

(N/A) Addiction is a psychological attachment to certain effects,such as euphoria and a temporary feeling of well-being,associated with drugs and alcohol. Even when the user knows that the use of these substances is harmful,they continue to consume them due to this psychological craving.
With repeated use of drugs or alcohol,the tolerance level of the receptors in our body increases. Consequently,the receptors respond only to higher doses of these substances,leading to greater intake and addiction.
Dependence is the tendency of the body to manifest a characteristic and unpleasant 'withdrawal syndrome' if regular doses of drugs or alcohol are abruptly discontinued. Symptoms of withdrawal syndrome include anxiety,shakiness,nausea,and sweating. These symptoms may be relieved when the use of the substance is resumed. In some cases,withdrawal symptoms can be severe and life-threatening,requiring medical supervision.
Due to dependence,the individual may ignore social norms and engage in illegal or unethical activities to procure the substances,leading to serious social and personal problems.

(N/A) The immediate adverse effects of drug and alcohol abuse manifest as reckless behavior, vandalism, and violence. Excessive doses of drugs may lead to coma and death due to respiratory failure, heart failure, or cerebral hemorrhage. $A$ combination of drugs or their intake along with alcohol generally results in overdosing and even death.
Warning signs of drug and alcohol abuse in youth include a drop in academic performance, unexplained absence from school or college, lack of interest in personal hygiene, withdrawal, isolation, depression, fatigue, aggressive and rebellious behavior, deteriorating relationships with family and friends, loss of interest in hobbies, changes in sleeping and eating habits, and fluctuations in weight and appetite.
There are also long-term adverse effects. If an addict is unable to get money to buy drugs or alcohol, they may turn to stealing. The adverse effects are not limited to the individual; an addict can cause mental and financial distress to their family and friends.
Those who take drugs intravenously (direct injection into the vein using a needle or syringe) are at high risk of acquiring $AIDS$ and $Hepatitis-B$. The viruses for these diseases spread from one person to another through shared needles or syringes. Both $AIDS$ and $Hepatitis-B$ infections are chronic and ultimately fatal. They are also transmitted through sexual contact or infected blood.
Alcohol consumption during adolescence often leads to long-term addiction in adulthood. Chronic use of drugs and alcohol damages the nervous system and the liver (causing $cirrhosis$). Use of drugs and alcohol during pregnancy also adversely affects the fetus.
In other forms of abuse, some athletes use drugs to enhance performance. They use narcotic analgesics, anabolic steroids, diuretics, and certain hormones to increase muscle strength and bulk and to promote aggressiveness, resulting in better athletic performance.
In females, side effects of anabolic steroids include masculinization (features like the male), increased aggressiveness, mood swings, depression, menstrual cycle irregularities, excessive hair growth on the face and body, enlargement of the clitoris, and deepening of the voice.
In males, side effects include acne, increased aggressiveness, mood swings, depression, reduction of the size of the testicles, decreased sperm production, potential for kidney and liver dysfunction, breast enlargement, premature baldness, and enlargement of the prostate gland.
These effects are more pronounced with long-term use. In adolescent boys and girls, these can cause severe facial and body acne and premature closure of the growth centers of long bones, resulting in stunted growth.

(N/A) $1$. Avoid undue peer pressure: Every child has their own choice and personality,which should be respected and nurtured. $A$ child should not be pushed unduly to perform beyond their threshold limits,whether in studies,sports,or other activities.
$2$. Education and counseling: Educating and counseling the child to face problems and stresses,and to accept disappointments and failures as a part of life. It is beneficial to channelize the child's energy into healthy pursuits like sports,reading,music,yoga,and other extracurricular activities.
$3$. Seeking help from parents and peers: Help from parents and peers should be sought immediately so that they can guide appropriately. Help may also be sought from close and trusted friends. Besides getting proper advice to sort out problems,this helps young people vent their feelings of anxiety and guilt.
$4$. Looking for danger signs: Alert parents and teachers need to look for and identify danger signs. Even friends,if they find someone using drugs or alcohol,should not hesitate to bring this to the notice of parents or teachers in the best interests of the person concerned. Appropriate measures are then required to diagnose the underlying causes and initiate remedial steps or treatment.
$5$. Seeking professional and medical help: $A$ lot of help is available in the form of highly qualified psychologists,psychiatrists,and de-addiction and rehabilitation programs. With such help,and the individual's own efforts and willpower,they can get rid of the problem completely and lead a normal,healthy life.

(B) Strict enforcement of laws regarding addictive drugs is essential because:
$1$. Drugs like opioids,cannabinoids,and coca alkaloids have high potential for abuse and addiction.
$2$. These substances cause severe physiological and psychological damage,leading to organ failure,neurological disorders,and behavioral changes.
$3$. Illegal trafficking and misuse lead to social instability,increased crime rates,and health crises.
$4$. Strict regulations help in monitoring medical usage and preventing diversion into the black market,thereby protecting public health.

(N/A) When an addicted person is deprived of their regular dose of drugs or alcohol,the body reacts with a set of characteristic symptoms known as withdrawal symptoms. These occur because the body has become physiologically dependent on the substance. Four common withdrawal symptoms include:
$(a)$ Anxiety
$(b)$ Shakiness (tremors)
$(c)$ Nausea
$(d)$ Sweating
Other symptoms may include muscular twitching and extreme nervousness.

(N/A) This structure represents Cannabinoids.
$(b)$ These drugs are generally taken by inhalation and oral ingestion.
$(c)$ The cardiovascular system of the body is primarily affected by the consumption of these drugs.

(N/A) Many plants,fruits,and seeds possess hallucinogenic properties.
$\Rightarrow$ These have been used for centuries in folk medicine,religious ceremonies,and rituals across the globe.
When these substances are consumed for purposes other than medicinal use,or in amounts/frequencies that impair an individual's physical,physiological,or psychological functions,it constitutes drug abuse.
For example,$Morphine$ is a secondary metabolite obtained from $Papaver$ $somniferum$. The acetylation of $Morphine$ produces $Heroin$,which is a highly addictive drug.

(N/A) Cannabinoids,anabolic steroids,and certain hormones are misused by athletes to enhance their performance.
The misuse of these substances is associated with severe side effects:
$(a)$ In females: $(1)$ masculinization,$(2)$ increased aggressiveness,$(3)$ mood swings,$(4)$ abnormal menstrual cycles,$(5)$ enlarged clitoris.
$(b)$ In males: $(1)$ increased acne,$(2)$ mood swings,$(3)$ reduced testicular size,$(4)$ decreased spermatogenesis,$(5)$ enlarged breasts,$(6)$ enlarged prostate gland,$(7)$ dysfunction of liver and kidney.
Due to these harmful health effects and the unfair advantage they provide,their use is prohibited in sports.

(N/A) The use of drugs and alcohol often provides a temporary sense of euphoria or 'high',which acts as a psychological reinforcement for the user.
However,this is followed by severe long-term damages to the physical and mental health of the individual.
Common causes that motivate youngsters towards drug and alcohol use include curiosity,a need for adventure and excitement,and experimentation.
Initially,the use may be driven by curiosity,but it often progresses to a coping mechanism to escape from real-life problems.
Academic pressure and the stress to excel in examinations are significant factors that persuade youth to turn to these substances.
Social perceptions,such as the belief that smoking or using drugs is 'cool' or a sign of being progressive,are heavily influenced by media,including television,movies,and the internet.
Additionally,unstable or unsupportive family structures and peer pressure play a critical role in the initiation and continuation of drug and alcohol abuse among adolescents.

(N/A) - Cannabinoids are obtained from the inflorescence of the plant $Cannabis \text{ } sativa$.
- Marijuana, hashish, charas, and ganja are some examples of cannabinoids.
- These chemicals interact with cannabinoid receptors of the body, which are mainly present in the brain.
- The cardiovascular system of the body is also affected adversely by their consumption.

(N/A) The reasons why adolescents and youngsters start consuming drugs are:
$(i)$ Curiosity: The child is motivated to experiment.
$(ii)$ Need for adventure and excitement.
$(iii)$ Peer group pressure.
$(iv)$ Desire to perform better in physical and mental tasks.
$(v)$ To overcome frustration and depression resulting from failure in examinations or other activities.
$(vi)$ Unstable or unsupportive family structures.
The following measures can be taken to avoid drug abuse:
$(i)$ Avoid undue pressure on the child to perform beyond their capability in studies,sports,or other activities.
$(ii)$ Education and counseling are essential to help individuals face stress and failure in life.
$(iii)$ Seeking help from parents,elders,and peers to share feelings and concerns.
$(iv)$ Identifying danger signs early and taking appropriate remedial measures.
$(v)$ Seeking professional and medical help for de-addiction and rehabilitation.

(N/A) The immediate adverse effects of alcohol abuse are manifested in the form of reckless behaviour,vandalism,and violence.
Excessive intake of alcohol may lead to severe health issues,including liver damage,heart failure,or cerebral hemorrhage.
The most common warning signs of alcohol abuse include: $(1)$ drop in academic or professional performance,$(2)$ unexplained absence from work or school,$(3)$ lack of interest in personal hygiene,$(4)$ withdrawal and isolation,$(5)$ depression,$(6)$ fatigue,aggressive and rebellious behaviour,$(7)$ deteriorating relationships with family and friends,$(8)$ loss of interest in hobbies,$(9)$ change in sleeping and eating habits,and $(10)$ fluctuations in weight and appetite.
If an addict is unable to get money to buy alcohol,he/she may turn to stealing,causing mental and financial distress to their entire family.
Measures to overcome the problem:
- Prevention is better than cure: Identify situations that may push an individual towards alcohol use and take remedial measures in time.
- Role of family and teachers: Parenting that combines high levels of nurturance with consistent discipline is associated with a lowered risk of substance abuse.
- Professional help: Seeking help from psychologists,psychiatrists,or de-addiction centers is crucial.
- Support systems: Encouraging the individual to join support groups like Alcoholics Anonymous and maintaining a strong social support network.

(D) The major adverse effects of the abuse of drugs like $LSD$, barbiturates, and amphetamines include:
$1$. $Central \ Nervous \ System \ (CNS)$ impairment: These drugs directly affect the brain, leading to altered perception, hallucinations, and impaired judgment.
$2$. $Psychological \ dependence$: Users often develop a strong psychological craving for the drug, leading to addiction.
$3$. $Physical \ health \ deterioration$: Chronic abuse can lead to cardiovascular issues, respiratory depression, liver damage, and neurological disorders.
$4$. $Behavioral \ changes$: Abuse often results in mood swings, aggression, social withdrawal, and a decline in cognitive performance.
$5$. $Withdrawal \ symptoms$: Abrupt cessation of these drugs can cause severe anxiety, tremors, seizures, and in extreme cases, death.

(C) The common warning signals of drug and alcohol abuse in adolescents include:
$1$. Drop in academic performance and unexplained absence from school or college.
$2$. Lack of interest in personal hygiene.
$3$. Withdrawal,isolation,depression,fatigue,and aggressive or rebellious behavior.
$4$. Deteriorating relationships with family and friends.
$5$. Loss of interest in hobbies and change in sleeping and eating habits.
$6$. Fluctuations in weight and appetite.

(A) The correct matches are as follows:
$(a)$ Ergot of fungus (Claviceps purpurea) is the source of the hallucinogen $LSD$ (Lysergic acid diethylamide).
$(b)$ Opium poppy (Papaver somniferum) is the source of morphine,which is a potent analgesic.
$(c)$ Erythroxylum coca is the source of cocaine,which is often processed into a potent stimulant form known as crack.
$(d)$ Cannabis sativa is the source of cannabinoids like marijuana.
Therefore,the correct matching is: $(a-3), (b-2), (c-4), (d-1)$.
