Drugs and Alcohol Abuse Questions in English

(A) $LSD$ stands for Lysergic acid diethylamide. It is a potent hallucinogenic drug derived from the fungus Claviceps purpurea.

(C) Opium is a dried latex obtained from the $Papaver$ $somniferum$ plant.
It is primarily extracted by making incisions in the $unripe$ $poppy$ $capsules$ (fruit).
The milky latex that exudes from these incisions is collected,dried,and processed to obtain opium.

(A) Diacetylmorphine is commonly known as $Heroin$. It is a depressant and slows down body functions. It is synthesized by the acetylation of morphine,which is extracted from the latex of the poppy plant,$Papaver$ $somniferum$.

(D) The plant $Papaver$ $somniferum$ (opium poppy) is the source of morphine.
Heroin,commonly known as 'smack',is chemically diacetylmorphine.
It is produced by the acetylation of morphine,which is extracted from the latex of $Papaver$ $somniferum$.
Therefore,smack,heroin,and acetylated morphine crystals all refer to the same substance derived from this plant.
Thus,the correct answer is $D$.

(A) $Cannabis \text{ sativa}$ is the plant source for cannabinoids. The flower tops, leaves, and resin of this plant are used to produce various substances such as marijuana, hashish, charas, and bhang. Therefore, bhang is obtained from $Cannabis \text{ sativa}$.

(D) Cannabinoids are a group of chemicals that interact with cannabinoid receptors present principally in the brain.
Natural cannabinoids are obtained from the inflorescence of the plant $Cannabis sativa$.
Bhang, Ganja, Charas, and Hashish are various forms of these cannabinoids.
Ganja is obtained from the unfertilized female inflorescences (flowers), while Bhang is primarily prepared from the dried leaves and flowering shoots of the plant.
Therefore, both leaves and flowers are used to obtain these substances.

(A) $1$. Sedatives are drugs that slow down brain activity and induce calmness or sleep. Heroin is a well-known depressant/sedative derived from morphine.
$2$. Cardiovascular-affecting components are substances that significantly alter heart rate and blood pressure. Marijuana (cannabinoids) is known to have a significant effect on the cardiovascular system of the body.
$3$. Therefore,Heroin acts as a sedative,and Marijuana acts as a cardiovascular-affecting component. The correct pair is Heroin and Marijuana.

(C) Cocaine, also known as coke or crack, is an alkaloid obtained from the plant $Erythroxylum$ $coca$.
It is a native plant of South America.
It interferes with the transport of the neurotransmitter dopamine.
Therefore, option $C$ is the correct answer.

(A) Hallucinogens are substances that alter thoughts, feelings, and perceptions. Plants like $Atropa$ $\text{belladonna}$ and $Datura$ are well-known for their hallucinogenic properties. They contain alkaloids that affect the central nervous system, leading to altered sensory experiences. While $Cannabis$ species also have psychoactive effects, $Atropa$ $\text{belladonna}$ is classically categorized as a potent hallucinogenic plant.

(B) Morphine is an opioid drug that is widely used in medicine as a potent analgesic (painkiller) for patients who have undergone surgery or are suffering from severe pain.
Heroin is a derivative of morphine but is primarily used as an illegal recreational drug.
Cocaine is a stimulant drug.
Datura is a hallucinogenic plant.
Therefore,the correct answer is $B$.

(B) The substances used to treat high stress and insomnia are known as sedatives and tranquilizers.
Among the given list,the substances that act as sedatives or tranquilizers are:
$1$. Barbiturates
$2$. Amphetamines (sometimes used for specific conditions,but primarily stimulants; however,in a clinical context,Benzodiazepines are the primary choice)
$3$. Benzodiazepines
Opium,Morphine,and Heroin are opioids (painkillers/narcotics). Charas,Ganja,Cocaine,and $LSD$ are hallucinogens or stimulants.
Therefore,the substances specifically used for stress and insomnia from the list are Barbiturates and Benzodiazepines.
However,in many medical contexts,Amphetamines are strictly stimulants and not used for insomnia. Thus,only $2$ substances (Barbiturates and Benzodiazepines) are typically used. Given the options,if we consider the clinical classification,the answer is $2$. Since $2$ is not an option,we re-evaluate: Barbiturates and Benzodiazepines are the correct ones. If the question implies a broader category,the answer is $2$. Given the provided options,there might be a discrepancy,but based on standard medical knowledge,the count is $2$.

(A) Nicotine is a stimulant drug found in tobacco smoke. Its effects are as follows:
$(i)$ It stimulates the adrenal gland to release adrenaline and nor-adrenaline,which increases blood pressure and heart rate. (Correct)
(ii) It does not decrease the respiratory rate; rather,it often increases it or irritates the respiratory tract. (Incorrect)
(iii) Tobacco smoke contains carcinogens that cause cancers of the lungs,throat,and bladder. (Correct)
(iv) It is not primarily known for inducing allergies. (Incorrect)
$(v)$ Smoking is a primary cause of emphysema,a chronic obstructive pulmonary disease. (Correct)
(vi) Smoking increases carbon monoxide $(CO)$ levels in the blood,which binds to hemoglobin more strongly than $O_2$,thereby decreasing the oxygen-carrying capacity of the blood. (Correct)
Therefore,statements $(i)$,(iii),$(v)$,and (vi) are correct. The total count is $4$.

(C) When an individual who is dependent on addictive substances (drugs or alcohol) suddenly stops their consumption,the body reacts negatively due to the absence of the substance. This set of unpleasant symptoms is known as $Withdrawal$ $syndrome$. Symptoms may include anxiety,shakiness,nausea,and sweating,which occur because the body has adapted to the presence of the drug.

(A) Excessive alcohol consumption leads to the accumulation of fat in liver cells,causing inflammation and damage. Over time,this results in the formation of scar tissue in the liver,a condition known as $Cirrhosis$. $Syphilis$ is a bacterial sexually transmitted infection. $Hepatitis$ is an inflammation of the liver,often caused by viruses. While chronic alcohol abuse can increase the risk of liver cancer,$Cirrhosis$ is the specific condition directly associated with long-term alcohol-induced liver damage.

(D) The excessive use of anabolic steroids in females leads to several side effects due to hormonal imbalance. These include:
$1$. Masculinization (features like 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 mental stress.
$6$. Increased aggressiveness.
Since options $A$,$B$,and $C$ are all recognized side effects of steroid abuse in females,the correct answer is $D$.

(A) The excessive use of anabolic steroids in males leads to several side effects,including acne,increased aggressiveness,mood swings,depression,reduction of testicles size,decreased sperm production,potential for kidney and liver dysfunction,breast enlargement (gynecomastia),premature baldness,and enlargement of the prostate gland.
Option $A$ states 'Increase in the size of testicles',which is incorrect because anabolic steroids actually cause a reduction in the size of testicles. Therefore,this is the side effect that is $NOT$ observed.

(B) Charas is a form of cannabis resin obtained from the plant $Cannabis$ $\text{sativa}$.
It belongs to the class of drugs known as cannabinoids.
Cannabinoids are known for their effects on the cardiovascular system and the brain.
Therefore, Charas is classified as a cannabinoid.

(C) When alcohol is consumed,it is metabolized in the liver. The enzyme alcohol dehydrogenase converts ethanol into $Acetaldehyde$. $Acetaldehyde$ is highly toxic and reactive,causing damage to liver cells (hepatocytes) and leading to conditions like fatty liver,hepatitis,and cirrhosis. Therefore,the primary harmful intermediate formed in the liver is $Acetaldehyde$.

(A) $LSD$ (Lysergic Acid Diethylamide) is derived from the fungus Claviceps purpurea. It is considered one of the most potent and dangerous hallucinogens known, as it causes profound alterations in perception, mood, and thought processes even in extremely small doses.

(A) Morphine is a potent opioid analgesic drug. It is extracted from the latex of the poppy plant,scientifically known as $Papaver$ $somniferum$.
$Papaver$ $somniferum$ is the source of opium,from which morphine,codeine,and heroin are derived.
$Erythroxylum$ $coca$ is the source of cocaine.
$Cannabis$ $sativa$ and $Cannabis$ $indica$ are sources of cannabinoids like marijuana,hashish,and charas.

(B) Cocaine is a potent stimulant drug derived from the leaves of the plant $Erythroxylum \text{ coca }$.
It acts by interfering with the transport of the neurotransmitter $Dopamine$.
Normally, $Dopamine$ is released into the synaptic cleft and then reabsorbed by the presynaptic neuron via $Dopamine$ transporters.
Cocaine blocks these transporters, preventing the reuptake of $Dopamine$.
This leads to an accumulation of $Dopamine$ in the synaptic cleft, causing continuous stimulation of the postsynaptic neurons, which results in the euphoric effects associated with cocaine use.

(C) Benzodiazepines are a class of psychoactive drugs whose core chemical structure is the fusion of a benzene ring and a diazepine ring. They are commonly prescribed to treat conditions such as insomnia,anxiety,and depression because they act as central nervous system depressants,helping to induce sleep and reduce stress levels. Barbiturates are also depressants but are less commonly used today due to higher risks of addiction and overdose compared to benzodiazepines. Amphetamines are stimulants,not depressants,and are generally used for conditions like $ADHD$ or narcolepsy,not for treating insomnia or depression.

(B) The plant $Papaver somniferum$,commonly known as the opium poppy,is the source of opium.
Opium is obtained by drying the latex (milky exudate) collected from the unripe capsules (fruits) of this plant.
While morphine and codeine are alkaloids derived from opium,opium itself is the raw substance extracted directly from the unripe fruit.

(C) Nicotine is a stimulant drug that acts on the central nervous system. It binds to nicotinic acetylcholine receptors,leading to increased nerve stimulation. At higher doses,it can also cause muscle relaxation or paralysis by blocking neuromuscular transmission. Therefore,nicotine is the correct component among the choices provided that exhibits these properties.

(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 reduces their intake.
Common symptoms of withdrawal syndrome include anxiety,shakiness (tremors),nausea,sweating,restlessness,and irritability.
These symptoms occur because the body has adapted to the presence of the substance,and its absence causes a physiological imbalance.
Therefore,the correct option is $C$.

(C) The correct matching is as follows:
$(1)$ $Datura$ is well-known for its hallucinogenic properties,so $(1-b)$.
$(2)$ $Erythroxylum$ $coca$ (cocaine) interferes with the transport of the neurotransmitter dopamine,so $(2-c)$.
$(3)$ $Papaver$ $somniferum$ (opium poppy) produces latex from which opioids like morphine are extracted,so $(3-d)$.
$(4)$ $Cannabis$ $sativa$ is a plant whose inflorescence (floral base) is used to produce cannabinoids like marijuana and hashish,so $(4-a)$.
Thus,the correct sequence is $1-b, 2-c, 3-d, 4-a$.

(C) $1$. $Cannabis sativa$ leaves are used to produce marijuana, which is correct.
$2$. $Datura$ is a well-known hallucinogenic plant, which is correct.
$3$. $LSD$ (Lysergic acid diethylamide) is a powerful hallucinogen, not a treatment for insomnia. Therefore, this statement is incorrect.
$4$. Morphine acts primarily on the $CNS$ (Central Nervous System) as a sedative and analgesic, not the $PNS$ (Peripheral Nervous System). Thus, this statement is also incorrect. However, in the context of typical multiple-choice questions regarding drug effects, $LSD$ being labeled as a treatment for insomnia is a blatant factual error regarding its pharmacological classification.

(B) Statement $(1)$ is correct: $Datura$ species are well-known for their hallucinogenic properties.
Statement $(2)$ is correct: $Atropa$ $belladonna$ contains alkaloids that cause hallucinations.
Statement $(3)$ is correct: Opium is extracted from the dried latex of the unripe capsules of the poppy plant ($Papaver$ $somniferum$).
Statement $(4)$ is correct: Marijuana,hashish,charas,and ganja are all obtained from the inflorescence of $Cannabis$ $sativa$.
Statement $(5)$ is incorrect: $LSD$ ($Lysergic$ $acid$ $diethylamide$) is a potent hallucinogen and is not used as a medicine; it is a drug of abuse.
Therefore,statements $(1), (2), (3),$ and $(4)$ are correct.

(C) The image provided shows the plant $Papaver$ $somniferum$,commonly known as the opium poppy. This plant is the source of opiates like morphine,which is extracted from the latex of its unripe capsules. These substances act on specific opioid receptors present in our central nervous system and gastrointestinal tract.

(C) The provided chemical structure represents a cannabinoid molecule. Cannabinoids are a group of substances that interact with cannabinoid receptors in the body. The structure shown is specifically that of a cannabinoid,which is typically obtained from the inflorescences of the plant Cannabis sativa. These compounds are known for their effects on the cardiovascular system of the body.

(A) The figure shows the plant $Datura$.
$Datura$ is well-known for its hallucinogenic properties,which cause illusions or delusions (hallucinations).
Therefore,the correct option is $A$.

(B) The correct matching is as follows:
$(a)$ Poppy plant: This plant is the source of morphine,which is chemically processed to form Diacetyl morphine (Heroin). Thus,$(a)-(ii)$.
$(b)$ Cannabis plant: This plant is the source of cannabinoids like marijuana,hashish,charas,and ganja. Thus,$(b)-(i)$.
$(c)$ Datura plant: This plant is well-known for its hallucinogenic properties. Thus,$(c)-(iii)$.
Therefore,the correct sequence is $(a)-ii, (b)-i, (c)-iii$,which corresponds to option $(B)$.

(D) Cocaine is a potent stimulant drug that is extracted from the leaves of the coca plant, known scientifically as $Erythroxylum coca$.
It interferes with the transport of the neurotransmitter dopamine, leading to increased levels of dopamine in the brain, which causes euphoria and increased energy.

(D) Tobacco contains a large number of chemical substances,including nicotine,which is an alkaloid.
Nicotine acts as a stimulant by binding to nicotinic acetylcholine receptors.
It stimulates the adrenal glands to release adrenaline and noradrenaline into the blood circulation.
Both of these hormones increase blood pressure and heart rate.

(A) In an alcoholic person,a portion of alcohol is metabolized into acetaldehyde,which stimulates the synthesis of fat.
This fat is deposited on the walls of arteries and also accumulates within the liver cells.
As a result,the liver function is impaired,leading to poor regulation of carbohydrate,protein,and fat metabolism.
This condition is known as fatty liver syndrome.
Over time,the liver tissue becomes solid,hard,and fibrous,a condition clinically referred to as liver cirrhosis.

(D) Cocaine is a potent stimulant of the central nervous system.
An excessive dosage or overdose of cocaine can lead to severe physiological and psychological effects.
These effects include intense hallucinations,respiratory distress or failure,and cardiovascular failure,which can ultimately lead to death.

(B) Cocaine is an alkaloid obtained from the coca plant, $Erythroxylum$ $\text{coca}$.
This plant is native to the high mountain ranges of South America, particularly the Andean regions.

(A) Cocaine is a potent stimulant drug that is a crystalline alkaloid. It is extracted from the leaves of the coca plant, scientifically known as $Erythroxylum$ $coca$. This plant is native to South America and its leaves contain the active compound that interferes with the transport of the neurotransmitter dopamine.

(B) Teratogens are substances or chemical compounds that cross the placenta and damage the developing fetus,causing malformations in the embryo.
Examples of teratogens include drugs like thalidomide,alcohol,and certain medications.

(A) The symptoms described,such as increased aggressiveness,mood swings,depression,reduction in the size of the testicles,decreased sperm production,breast enlargement,and premature baldness,are classic side effects of the misuse of $Anabolic$ $steroids$ in males.
Other potential side effects include kidney and liver dysfunction,and enlargement of the prostate gland.

(C) Smack,also known as heroin,is a diacetylmorphine compound. It is a white,odourless,bitter,crystalline compound obtained by acetylation of morphine. It is generally taken by snorting or injection.

(A) $A-$Adrenal gland,$B-$Adrenaline,$C-$Nor-adrenaline,$D-$Blood pressure,$E-$Heart rate.
Tobacco contains a large number of chemical substances including nicotine,an alkaloid.
Nicotine stimulates the adrenal gland to release adrenaline and noradrenaline into the blood circulation,both of which raise blood pressure and increase heart rate.
Smoking is associated with an increased incidence of cancers of the lung,urinary bladder,and throat,as well as bronchitis,emphysema,coronary heart diseases,and gastric ulcers.

(A) Cocaine is a stimulant drug obtained 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. It also significantly increases cardiovascular effects, such as heart rate and blood pressure, in human beings.

(C) Diacetyl morphine is a white, odorless, bitter crystalline compound. It is commonly known as heroin. It is obtained by the acetylation of morphine, which is extracted from the latex of the poppy plant, $Papaver$ \text{ somniferum}.

(D) Heroin,commonly known as smack,is chemically diacetylmorphine which is a white,odourless,bitter,crystalline compound. This is obtained by acetylation of morphine,which is extracted from the latex of the poppy plant $Papaver$ $somniferum$.
Generally taken by snorting and injection,it is a depressant and slows down body functions.
Cocaine is obtained from $Erythroxylum$ $coca$,generally snorted. It causes hallucinations and has a potent stimulating effect on the central nervous system,producing a sense of euphoria and increased energy.
Hashish is obtained from the $Cannabis$ plant,usually taken by inhalation and oral ingestion. It has significant effects on the cardiovascular system.
Barbiturates are sedatives used as medicines to help patients cope with mental illnesses like depression and insomnia. They reduce excitement by depressing the $CNS$ activity and lower physiological activity,leading to drowsiness or sleep.

(D) $Cannabis$ products,such as marijuana,$ganja$,$charas$,and $hashish$,are known to affect the cardiovascular system and the brain.
They are primarily known for causing hallucinations,which involve the alteration of perception,thoughts,and feelings in the user.

(D) Statement $(a)$ is correct: Heroin,also known as smack,is diacetylmorphine,which is obtained by the acetylation of morphine.
Statement $(b)$ is incorrect: Cocaine is obtained from the plant $Erythroxylum \; coca$,whereas $Papaver \; somniferum$ is the source of morphine.
Statement $(c)$ is incorrect: Dopamine can act as both an excitatory and inhibitory neurotransmitter depending on the receptor,but in the context of drug addiction pathways,it is often discussed for its role in reward signaling; however,it is not strictly classified as purely excitatory in all contexts.
Statement $(d)$ is correct: Morphine is a very effective sedative and painkiller,widely used in medicine for patients who have undergone surgery.

(A) Hallucinogens are substances that alter a person's thoughts,feelings,and perceptions without any actual sensory stimulus.
$L.S.D.$ (Lysergic acid diethylamide) is a well-known hallucinogen.
Sedatives,such as barbiturates and benzodiazepines,depress brain activity and produce feelings of calmness,relaxation,drowsiness,and deep sleep.
Stimulants,such as caffeine,cocaine,and amphetamines,stimulate the nervous system,increase alertness,and produce excitement.
Tranquilisers,such as benzodiazepines,act as anti-depressants and help in reducing anxiety.

(C) The correct match for the drug 'Coca' (or Cocaine) is the plant 'Erythroxylum coca'.
'Atropa belladonna' is a plant known for its hallucinogenic properties,but it is not the source of 'Coca'.
Therefore,the match 'Coca - Atropa belladonna' is incorrect.
All other options provided (Smack,Cocaine,and Hashish) are correctly matched with their respective sources and physiological actions.

(D) $LSD$ (Lysergic acid diethylamide) and marijuana are classified as hallucinogens,not analgesics.
Analgesics are pain-relieving drugs,whereas hallucinogens alter thoughts,feelings,and perceptions.
Furthermore,these drugs do not simply suppress brain function; they significantly distort sensory perception and cognitive processes.
Therefore,both the Assertion and the Reason are incorrect.
