Drugs and Alcohol Abuse Questions in English

(B) The repeated use of drugs or alcohol leads to an increase in the tolerance level of the receptors present in the body. As a result,the receptors respond only to higher doses of drugs or alcohol,leading to greater intake and addiction. Therefore,the correct answer is $B$ (Receptors).

(C) Withdrawal syndrome refers to the set of physical and psychological symptoms that occur when an individual who is dependent on a substance (such as drugs or alcohol) suddenly stops or significantly reduces their intake.
These symptoms are often unpleasant and can include anxiety,tremors,nausea,sweating,and irritability.
This occurs because the body has adapted to the presence of the substance,and its sudden absence disrupts normal physiological functioning.
Therefore,the correct definition is the sudden cessation of drugs or alcohol.

(A) When drugs or alcohol are taken regularly, the body becomes dependent on them.
If these substances are suddenly stopped, the body experiences a set of unpleasant symptoms known as $Withdrawal \text{ } syndrome$.
These symptoms occur because the body has adapted to the presence of the substance and struggles to function normally without it.
Common symptoms include anxiety, shakiness, nausea, and sweating.

(B) When drugs or alcohol are taken repeatedly,the receptors present in our body respond only to higher doses of the drug or alcohol. This phenomenon is known as tolerance. As the body adapts to the presence of the substance,the receptors become less sensitive,requiring a higher concentration of the drug to produce the same effect. Therefore,the tolerance level of the receptors increases.

(D) Statement $(i)$ is correct: Repeated use of drugs increases the tolerance level of receptors in the body,requiring higher doses for the same effect.
Statement $(ii)$ is incorrect: Youngsters typically use drugs due to curiosity,peer pressure,or stress,not for financial gains.
Statement $(iii)$ is correct: Lack of proper guidance,counseling,or family support is a major factor leading to addiction.
Statement $(iv)$ is correct: Withdrawal syndrome occurs when a person who is addicted to alcohol or drugs suddenly stops using them,leading to severe physical and psychological symptoms.
Therefore,statements $(i)$,$(iii)$,and $(iv)$ are correct.

(B) When a person repeatedly uses drugs,the body adapts to the presence of the substance. This phenomenon is known as tolerance. As a result,the body requires higher doses of the drug to achieve the same initial effect,which means the tolerance level increases.

(A) When a person who is addicted to drugs or alcohol suddenly stops their intake,the body experiences a set of unpleasant symptoms known as $Withdrawal$ $syndrome$.
These symptoms occur because the body has become physiologically dependent on the substance.
Common symptoms include anxiety,shakiness,nausea,and sweating,which are relieved once the regular dose is resumed.

(D) Withdrawal syndrome refers to the set of symptoms that occur when a person who is dependent on a substance (such as drugs or alcohol) suddenly stops or reduces their intake.
Common symptoms of withdrawal syndrome include anxiety,shakiness,nausea,sweating,and sometimes even seizures or hallucinations.
Since anxiety,nausea,and sweating are all characteristic symptoms,the correct answer is $D$.

(C) Withdrawal syndrome refers to the set of symptoms that occur when a person who is dependent on a substance (like drugs or alcohol) suddenly stops or reduces their intake.
Common symptoms of withdrawal syndrome include anxiety,shakiness,nausea,sweating,dizziness,and muscle aches.
An increase in blood sugar level is not a characteristic symptom of withdrawal syndrome.
Therefore,the correct option is $C$.

(A) Withdrawal syndrome refers to the set of physical and psychological symptoms that occur when a person stops or reduces the use of a substance (like alcohol or drugs) to which they are addicted.
To get relief from withdrawal syndrome,the most effective approach is to seek professional medical help and counseling to gradually manage the symptoms and stay away from the addiction.
Using the substance again (Option $B$) only perpetuates the cycle of addiction.
Vaccination (Option $C$) and antibiotics (Option $D$) are not treatments for withdrawal syndrome.
Therefore,staying away from addiction through proper rehabilitation and support is the correct approach.

(A) The correct answer is $A$. Cirrhosis is a chronic liver disease characterized by the replacement of liver tissue with scar tissue,often caused by chronic alcohol abuse,not kidney disease. Therefore,the statement that chronic drug use causes 'kidney disease like cirrhosis' is scientifically incorrect. Other options are correct: drug abuse causes mental instability and financial distress $(B)$,affects fetal development during pregnancy $(C)$,and can lead to fatal cardiac arrest due to overdose $(D)$.

(D) Drug abuse through shared needles or syringes is a major mode of transmission for blood-borne pathogens.
$(iii)$ $AIDS$ (Acquired Immuno Deficiency Syndrome) is caused by the $HIV$ virus,which spreads through the sharing of infected needles.
$(iv)$ Hepatitis-$B$ is also a blood-borne viral infection that is transmitted through contaminated needles and syringes.
Therefore,individuals who use intravenous drugs are at a high risk of contracting both $AIDS$ and Hepatitis-$B$.

(C) Drug abuse leads to several adverse effects on the human body and mind. Common harmful effects include rebellious behavior,increased aggressiveness,mood swings,depression,and unexplained weight loss. Stress is often a pre-existing condition or a psychological state that may lead an individual to abuse drugs,rather than being a direct harmful effect caused by the drug itself. Therefore,stress is not considered a direct harmful effect of drug abuse.

(D) Liver cirrhosis is a chronic liver disease characterized by the replacement of healthy liver tissue with scar tissue.
Chronic consumption of alcohol is a primary cause of liver cirrhosis.
Alcohol is metabolized in the liver,and its excessive intake leads to inflammation,cell death,and eventually fibrosis (scarring) of the liver tissue,which impairs its normal functions.

(C) The use of anabolic steroids in males leads to several side effects,including a reduction in the size of testicles,decreased sperm production,baldness,enlargement of the prostate gland,and mood swings. Therefore,the correct answer is $C$.

(D) Chronic use of alcohol and drugs has severe adverse effects on the human body:
$1$. Liver: Excessive alcohol consumption leads to the accumulation of fat in the liver,known as fatty liver,which eventually progresses to 'Liver Cirrhosis',a potentially fatal condition.
$2$. Nervous System: Drugs and alcohol directly affect the Central Nervous System $(CNS)$,leading to memory loss,mental instability,and permanent damage to the nervous system.
$3$. Other effects: The use of drugs via shared needles significantly increases the risk of infectious diseases like $AIDS$ and Hepatitis-$B$.
Therefore,option $D$ is the most comprehensive and accurate answer.

(A) The use of anabolic steroids in both males and females leads to several common side effects.
These include:
$(i)$ Increased aggressiveness,
$(iv)$ Depression,
$(v)$ Acne.
Other side effects like $(ii)$ Irregular menstrual cycles and $(vi)$ Reduced size of testicles are gender-specific (females and males respectively),and $(iii)$ Baldness is more commonly associated with males.
Therefore,the common side effects observed in both genders from the given list are $(i), (iv)$ and $(v)$.

(D) Anabolic steroids are synthetic derivatives of testosterone. When used by females,they cause several side effects due to hormonal imbalance. These include:
$1$. Masculinization: Development of male-like features such as increased hair growth on the face and body.
$2$. Deepening of the voice.
$3$. Enlargement of the clitoris.
$4$. Irregularity in the menstrual cycle.
$5$. Excessive mood swings,depression,and increased aggressiveness.
Therefore,all the given options are correct side effects observed in females.

(A) The use of anabolic steroids in males leads to several side effects,including:
$1$. Acne
$2$. Increased aggressiveness
$3$. Mood swings
$4$. Depression
$5$. Reduction in size of testicles
$6$. Reduction in sperm production
$7$. Potential for kidney and liver dysfunction
$8$. Breast enlargement
$9$. Premature baldness
$10$. Enlargement of the prostate gland
Irregularity in the menstrual cycle is a side effect observed in females,not males. Therefore,option $A$ is the correct answer.

(C) The consumption of drugs and alcohol during adolescence has severe psychological and social consequences.
$1$. It leads to a significant decline in academic performance due to lack of concentration and motivation.
$2$. It also manifests in behavioral changes such as increased stress,irritability,aggressiveness,and rebellious attitudes towards family and society.
Therefore,both the adverse effects on academic performance and the psychological changes mentioned are correct outcomes of substance abuse in adolescents.

(D) Excessive consumption of drugs or narcotics leads to severe physiological and psychological damage.
$1$. Respiratory failure: High doses of drugs like opioids can suppress the respiratory center in the brain,leading to respiratory failure.
$2$. Heart failure: Stimulants or excessive drug use can cause cardiac arrhythmias or heart failure.
$3$. Deterioration of health: Chronic drug abuse leads to the breakdown of the immune system,liver damage,and overall physical and mental decline.
Therefore,all the mentioned effects are observed due to the excessive consumption of drugs.

(D) Liver cirrhosis is a chronic condition characterized by the replacement of healthy liver tissue with scar tissue.
Chronic consumption of alcohol is the most common cause of liver cirrhosis.
Alcohol is metabolized in the liver,and its excessive intake leads to inflammation,cell death,and eventually fibrosis (scarring) of the liver tissue,which impairs its normal functions.

(D) Caffeine is a central nervous system stimulant. Excessive consumption of caffeine can lead to various physiological effects,including:
$1$. Increased heart rate and palpitations (affects heart rate).
$2$. Increased breathing rate or respiratory distress (affects the respiratory system).
$3$. In extreme cases of toxicity or overdose,it can lead to severe cardiac arrhythmias or seizures,which may result in death.
Therefore,all the given options are correct consequences of excessive caffeine intake.

(D) The combined consumption of alcohol and drugs (such as sedatives,opioids,or stimulants) leads to a synergistic effect on the central nervous system. This combination significantly depresses respiratory and cardiac functions,leading to severe physiological failure. In many cases,this interaction results in coma or death due to respiratory failure or cardiovascular collapse.

(C) During pregnancy,the placenta acts as a bridge between the mother and the fetus. If a pregnant woman consumes drugs,these substances can cross the placental barrier and enter the fetal bloodstream. This can lead to developmental issues,congenital abnormalities,or addiction in the fetus. Therefore,the fetus is the primary individual affected by the consumption of drugs during pregnancy.

(D) Athletes often misuse certain substances to enhance their physical performance and muscle mass.
$1$. Anabolic steroids are synthetic derivatives of testosterone,which are misused to increase muscle strength and bulk.
$2$. Certain hormones,such as growth hormones or erythropoietin,are also misused to improve performance.
$3$. Narcotics are sometimes used for pain management,but their misuse is also prevalent.
Therefore,all the listed options are substances that are misused by athletes to enhance performance and muscle strength.

(D) Anabolic steroids are synthetic derivatives of testosterone. When used by females,they cause several masculinizing side effects. These include:
$1$. Increased aggressiveness and mood swings.
$2$. Depression.
$3$. Irregularity in the menstrual cycle.
$4$. Excessive hair growth on the face and body (hirsutism).
$5$. Deepening of the voice.
$6$. Enlargement of the clitoris.
Since options $A$,$B$,and $C$ are all recognized side effects of steroid abuse in females,the correct answer is $D$.

(A) Anabolic steroids are synthetic derivatives of testosterone. When used by females,they cause masculinization effects. Common side effects in females include:
$1$. Masculinization (development of male-like features like deepening of voice,enlargement of clitoris).
$2$. Excessive hair growth on the face and body (hirsutism).
$3$. Irregularity in the menstrual cycle.
$4$. Mood swings,depression,and aggression.
Baldness (specifically male-pattern baldness) is a side effect typically associated with the use of anabolic steroids in males,not females.

(D) The use of anabolic steroids in both males and females leads to several common side effects.
These include increased aggressiveness,mood swings,depression,reduction in the size of testicles (in males),decreased sperm production,potential for kidney and liver dysfunction,breast enlargement,premature baldness,enlargement of the prostate gland,and stunted growth.
Since both increased aggressiveness and depression are listed as common side effects for both genders,the correct answer is $(D)$.

(D) The use of anabolic steroids in males leads to several adverse side effects. These include:
$1$. Acne $(A)$.
$2$. Increased aggressiveness and mood swings.
$3$. Reduction in the size of testicles $(B)$.
$4$. Decreased sperm production.
$5$. Potential for kidney and liver dysfunction.
$6$. Premature baldness $(C)$.
$7$. Enlargement of the prostate gland.
Therefore,all the listed options are correct side effects of steroid abuse in males.

(B) Anabolic steroids are synthetic derivatives of testosterone. In males,their use leads to several side effects including:
$1$. Acne $(A)$.
$2$. Increased aggressiveness.
$3$. Mood swings and depression.
$4$. Reduction of size of testicles.
$5$. Decreased sperm production $(A)$.
$6$. Potential for kidney and liver dysfunction $(D)$.
$7$. Premature baldness.
$8$. Enlargement of the prostate gland.
Irregularity in the menstrual cycle $(B)$ is a side effect observed in females,not in males,because males do not have a menstrual cycle. Therefore,option $B$ is the correct answer.

(D) When a friend is involved in drug abuse,a comprehensive approach is necessary to help them effectively.
$(i)$ Discussing with parents is crucial for professional intervention.
$(ii)$ Informing a teacher ensures the school can provide support.
$(iii)$ Advising them to avoid substances is a direct,necessary step.
$(iv)$ Showing empathy helps in understanding the root cause of the addiction.
$(v)$ Educating them about the health hazards helps in creating awareness.
$(vi)$ Providing guidance and support is essential for rehabilitation.
Therefore,all the mentioned steps are appropriate and necessary for helping a friend overcome drug abuse.

(D) Adolescence is a vulnerable period for drug and alcohol abuse.
To prevent and manage addiction,a collective effort is required.
Parents play a crucial role in monitoring and providing emotional support.
Teachers are responsible for creating awareness and identifying behavioral changes in students.
Friends can provide positive peer influence and support.
Therefore,all these groups share the responsibility to guide and protect adolescents from substance abuse.

(D) The energy of adolescents should be channeled into constructive and healthy activities to prevent them from falling into habits like drug or alcohol abuse. Engaging in activities such as $A$ (Music),$B$ (Yoga),and $C$ (Reading) helps in the holistic development of an individual,improves mental well-being,and keeps them away from harmful substances. Therefore,all these activities are beneficial.

(D) Adolescence is a vulnerable period for the initiation of drug and alcohol abuse.
Parents and teachers play a crucial role in the upbringing and guidance of adolescents.
They are responsible for monitoring the behavior,providing emotional support,and creating awareness about the harmful effects of substance abuse.
Therefore,both parents and teachers must take careful responsibility to prevent and address addiction in adolescents.

(B) $Morphine$ is a potent opioid analgesic derived from the poppy plant $(Papaver somniferum)$. It is widely used in clinical settings as a powerful painkiller for patients who have undergone surgery or are suffering from severe pain.
- Option $A$ is incorrect because sedatives induce sleep or calmness,not necessarily truth-telling.
- Option $C$ is incorrect because tobacco contains nicotine,which stimulates the adrenal gland to release adrenaline and nor-adrenaline,thereby increasing blood pressure and heart rate.
- Option $D$ is incorrect because cocaine is a stimulant drug that acts on the central nervous system and is not used for post-operative recovery.

(C) $LSD$ (Lysergic acid diethylamide) is a well-known hallucinogenic drug.
It is classified as a psychedelic drug because it causes optical and auditory hallucinations and induces significant behavioural abnormalities in the user.
Opium and morphine are classified as opiate narcotics,which act as depressants that suppress brain activity and are used to relieve pain.
Caffeine is a central nervous system stimulant that temporarily increases alertness and stimulates the nervous system.

(B) : Cirrhosis is a condition in which the liver responds to injury or death of some of its cells by producing interlacing strands of fibrous tissue,between which are nodules of regenerating cells. The liver becomes tawny and characteristically knobbly due to the presence of these nodules. Chronic alcohol consumption is a primary cause of this condition,known as alcoholic cirrhosis.

(B) : Morphine is a potent opioid analgesic used mainly to relieve severe and persistent pain,particularly in terminally ill patients or those who have undergone surgery.
It also induces feelings of euphoria.
It is administered by mouth,injection,or in suppositories.
Common side effects are nausea,vomiting,constipation,and drowsiness.
With regular use,tolerance develops and dependence may occur.

(C) : Hashish or charas is a pure resin obtained from the female flowers and leaves of selected varieties of $Cannabis$ $sativa$. It is the most potent hemp product (cannabinoids) and is usually smoked with tobacco. Its use may lead to euphoria,hallucinations,drowsiness,and continuous laughing. Hallucinogens act mainly on the $CNS$ and greatly alter one's thoughts,feelings,and perceptions.

(C) Morphine is a potent analgesic and sedative drug that belongs to the class of opioids.
It is extracted from the latex of the unripe capsules of the poppy plant,scientifically known as $Papaver$ $somniferum$.
$Cajanus$ $cajan$ is the pigeon pea,$Cannabis$ $sativa$ is the source of cannabinoids like marijuana and hashish,and $Rauwolfia$ $serpentina$ is the source of reserpine.

(B) Cocaine is a potent central nervous system stimulant derived from the plant $Erythroxylum$ $\text{coca}$.
It acts by interfering with the reuptake of the neurotransmitter $Dopamine$ at the synaptic cleft.
By blocking the dopamine transporter, cocaine causes an accumulation of $Dopamine$ in the synapse, which leads to continuous stimulation of the postsynaptic neurons, resulting in the characteristic euphoric effects and increased energy associated with its use.

(B) When drugs are used repeatedly,the receptors in the body become accustomed to the presence of the drug. As a result,the body requires higher doses of the drug to achieve the same effect,which is known as an increase in the tolerance level. Therefore,the tolerance level of the receptors increases with repeated drug use.

(A) Chronic use of drugs and alcohol has severe adverse effects on the human body.
$1$. The $Nervous system$ is primarily affected by drugs, leading to impaired cognitive functions, addiction, and behavioral changes.
$2$. The $Liver$ is the primary organ responsible for the detoxification of alcohol and drugs. Prolonged exposure leads to conditions like cirrhosis, fatty liver, and hepatitis.
Therefore, the most significant damage occurs in the $Nervous system$ and the $Liver$.

(D) The prevention and control of alcohol and drug abuse involve several proactive measures:
$1$. Avoid undue peer pressure: Each child has his/her own personality and choices. One should not push a child to perform beyond his/her threshold.
$2$. Seeking help from parents and peers: Help should be sought from parents and peers immediately so that they can provide appropriate guidance and support.
$3$. Education and counseling: Educating and counseling individuals to face problems and stresses,and to accept disappointments and failures as a part of life,is crucial.
Therefore,all the mentioned options are correct.

(C) $1$. $AIDS$ is not spread by touch,physical contact,or social interaction; it is transmitted through blood,sexual contact,or from mother to child.
$2$. Cannabinoids are a group of chemicals that interact with cannabinoid receptors in the brain. Heroin (smack) is produced by the acetylation of morphine,not cannabinoids.
$3$. Benzodiazepines are a class of drugs used to treat anxiety,insomnia,and other mental health conditions,including depression,by acting on the central nervous system.
$4$. $\alpha$-interferons are proteins produced by virus-infected cells that protect non-infected cells from further viral infection; they actually enhance the immune response,they do not decrease it.
Therefore,option $C$ is the correct statement.

(A) Tobacco contains an alkaloid known as $Nicotine$.
$Nicotine$ stimulates the adrenal gland to release adrenaline and nor-adrenaline into the blood circulation.
These hormones increase blood pressure and heart rate.
Therefore,the correct component is $Nicotine$.

(A) Smack, also known as heroin, is a diacetylmorphine derivative.
It is a depressant and slows down body functions.
It is chemically synthesized from morphine, which is extracted from the latex of the poppy plant, $Papaver$ $somniferum$.
Therefore, the correct option is $A$.

(D) Cannabinoids are a group of chemicals that interact with cannabinoid receptors present principally in the brain. Natural cannabinoids are obtained from the inflorescences of the plant $Cannabis \text{ } sativa$. The flower tops, leaves, and the resin of the $Cannabis \text{ } sativa$ plant are used in various combinations to produce marijuana, hashish, charas, and ganja. These drugs are known for their effects on the cardiovascular system of the body. Therefore, all the given options are correct.

(B) Hashish is a concentrated resinous product derived from the plant $Cannabis \text{ } sativa$.
It is obtained from the dried resinous exudate of the flowering tops and leaves of the plant.
$Papaver \text{ } somniferum$ yields opium, $Datura$ is a hallucinogen, and $Erythroxylum \text{ } coca$ is the source of cocaine.
