(N/A) Opioids are drugs that bind to specific opioid receptors present in our central nervous system and gastrointestinal tract.
Opioids are derived from the latex of the poppy plant,$Papaver$ $somniferum$.
Opium is obtained by making incisions in the unripe fruit capsules of the poppy plant. The milky latex that exudes dries and turns into a brownish,sticky substance known as opium.
Morphine and codeine are potent pain-relieving drugs (analgesics) extracted from opium. Morphine is a very effective sedative and painkiller and is very useful in patients who have undergone surgery.

Morphine:
- It is a potent analgesic (pain-relieving) drug extracted from the latex of the poppy plant,Papaver somniferum.
- It acts on the central nervous system $(CNS)$ by binding to specific opioid receptors,thereby blocking pain signals and providing relief from severe pain.
- It is often used as a sedative and painkiller in patients who have undergone surgery.
Codeine:
- Codeine is an opioid derivative,also obtained from the poppy plant.
- It is primarily used as a mild analgesic and as an antitussive (cough suppressant) in various cough syrups.
- It helps in reducing anxiety and stress,but like morphine,it has a high potential for abuse and addiction.

(C) Heroin,commonly called $smack$ or $brown$ $sugar$,is chemically known as $diacetylmorphine$.
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,$Papaver$ $somniferum$.
It is generally taken by snorting or injection.
Heroin acts as a depressant and slows down body functions.

Cannabinoids are a group of chemicals that interact with cannabinoid receptors present primarily in the brain.
- Natural cannabinoids are obtained from the inflorescences of the plant $Cannabis \text{ } sativa$.
- The flower tops, leaves, and resin of the cannabis plant are used in various combinations to produce marijuana, hashish, charas, and ganja.
- The main active element is $\Delta-9$ Tetrahydrocannabinol $(THC)$. It causes pupil dilation, increased blood sugar levels, and higher urine formation.
- Generally taken by inhalation and oral ingestion, these are known for their effects on the cardiovascular system.
- Cannabinoids are also misused by some sportspersons to enhance athletic performance.

(N/A) $1$. Coca alkaloids or cocaine is obtained from the coca plant,Erythroxylum coca,which is native to South America.
$2$. It is extracted from the dried leaves and young branches of the coca plant.
$3$. Cocaine interferes with the transport of the neurotransmitter dopamine in the brain.
$4$. Commonly known as 'coke' or 'crack',it is usually snorted.
$5$. It has a potent stimulating action on the central nervous system,producing a sense of euphoria and increased energy.
$6$. Excessive dosage of cocaine causes hallucinations,sleeplessness,and suppresses appetite.

(A) Drugs like barbiturates,amphetamines,and benzodiazepines are normally used as medicines to help patients cope with mental illnesses such as depression and insomnia.
$1$. Barbiturates are central nervous system depressants often used as sedatives or sleeping pills to treat insomnia.
$2$. Amphetamines are stimulants that increase alertness and are sometimes misused to stay awake.
$3$. Benzodiazepines are psychoactive drugs used to treat anxiety and insomnia.
These substances are frequently abused due to their psychoactive properties,leading to dependence and addiction.

(B) Several plants,fruits,and seeds having hallucinogenic properties have been used for hundreds of years in folk medicine,religious ceremonies,and rituals all over the globe.
When these substances are taken for a purpose other than medicinal use,or in amounts or frequencies that impair one's physical,physiological,or psychological functions,it constitutes drug abuse.

(B) $1$. Awareness: One must pay attention to the statutory warning present on cigarette packets,which clearly states that smoking is injurious to health.
$2$. Education: It is essential to understand the addictive nature of nicotine and the severe health risks associated with both smoking and chewing tobacco.
$3$. Avoidance: Youth and adults should consciously avoid these habits by staying away from peer pressure and environments where smoking is prevalent.
$4$. Support: If an individual is already addicted,seeking professional counseling and medical help is crucial to overcome these life-threatening habits.

(N/A) Adolescence is defined as both a period and a process during which a child matures in terms of attitudes and beliefs to participate effectively in society.
$\rightarrow$ The period between $12$ and $18$ years of age is generally considered the adolescence period.
$\rightarrow$ Adolescence acts as a bridge linking childhood and adulthood.
$\rightarrow$ It is accompanied by several biological and behavioral changes.
Adolescence is a highly vulnerable phase in the mental and psychological development of an individual.

(D) The primary reasons youngsters start using drugs or alcohol include:
$1$. Curiosity,the need for adventure,excitement,and experimentation are common motivators.
$2$. $A$ child's natural curiosity leads to experimentation,which is often reinforced by the perceived 'benefits' or effects of the substances.
$3$. While initial use may stem from curiosity,continued use often becomes a coping mechanism to escape life's problems.
$4$. Academic pressure and the stress to excel in examinations play a significant role in pushing youth toward substance use.
$5$. The social perception that smoking,drinking,or drug use is 'cool' or a sign of being progressive acts as a major catalyst.
$6$. Media influence,including television,movies,newspapers,and the internet,often promotes these harmful perceptions.
$7$. Unstable or unsupportive family structures and peer pressure are critical environmental factors associated with adolescent substance abuse.

(D) Addiction is primarily caused by the perceived benefits and psychological attachment to the effects of drugs and alcohol,such as euphoria and a temporary feeling of well-being.
$1$. Repeated use leads to an increase in the tolerance level of receptors in the body,requiring higher doses to achieve the same effect.
$2$. The inherent addictive nature of these substances creates a vicious cycle of dependency.
$3$. Even a single use can act as a precursor to addiction.
$4$. $A$ lack of proper guidance or counseling often traps individuals in this cycle,making it difficult to quit.
Therefore,all the mentioned factors contribute to the development of addiction.

(N/A) Dependence is the tendency of the body to manifest a characteristic and unpleasant withdrawal syndrome if the regular dose of drugs or alcohol is abruptly discontinued.
It is characterized by symptoms such as anxiety,shakiness,nausea,and sweating,which may be relieved when the use is resumed.
In some cases,withdrawal symptoms can be severe and even life-threatening,requiring medical supervision.
Dependence leads the individual to ignore all social norms to obtain sufficient funds to satisfy their needs,which results in many social adjustment problems.

(N/A) The immediate adverse effects of drug and alcohol abuse are manifested in the form of 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 deaths.
The most common warning signs of drug and alcohol abuse among youth include a drop in academic performance,unexplained absence from school/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,and changes in sleeping and eating habits,weight,and appetite.

(D) There are several far-reaching and extreme implications of drug and alcohol abuse:
$1$. Financial and Social Impact: If a user is unable to obtain money to purchase drugs or alcohol,they may resort to stealing. The adverse effects extend beyond the individual; an addict often causes severe mental and financial distress to their entire family and friends.
$2$. Risk of Serious Infections: Individuals who take drugs intravenously (direct injection into the vein using a needle and syringe) are at a high risk of acquiring serious infections like $AIDS$ and Hepatitis $B$. These viruses are transmitted by sharing infected needles and syringes.
$3$. Chronic Health Consequences: Both $AIDS$ and Hepatitis $B$ are chronic,often fatal infections. Furthermore,chronic use of drugs and alcohol causes permanent damage to the nervous system and the liver,leading to conditions like cirrhosis.
$4$. Long-term and Developmental Effects: Alcohol use during adolescence can lead to heavy drinking patterns in adulthood. Additionally,the use of drugs and alcohol during pregnancy is known to adversely affect the development of the foetus.

(N/A) Misuse of drugs is often practiced by certain sportspersons to enhance their performance.
They use narcotic analgesics,anabolic steroids,diuretics,and certain hormones in sports to increase muscle strength and bulk,promote aggressiveness,and consequently improve athletic performance.
The side effects of using anabolic steroids in females include masculinisation (development of male-like features),increased aggressiveness,mood swings,depression,abnormal menstrual cycles,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,potential for kidney and liver dysfunction,breast enlargement (gynecomastia),premature baldness,and enlargement of the prostate gland.
These effects may become permanent with prolonged use. In adolescent males or females,severe facial and body acne and the premature closure of the growth centers of the long bones may result in stunted growth.

(N/A) The age-old adage of "Prevention is better than cure" holds true because habits such as smoking, taking drugs, or alcohol are more likely to be initiated at a young age, particularly during adolescence.
Hence, it is best to identify the situations that may push an adolescent towards the use of drugs or alcohol and to take remedial measures well in time.
In this regard, parents and teachers have a special responsibility.
Parenting that combines high levels of nurturance with consistent discipline has been associated with a lowered risk of substance (alcohol, drugs, or tobacco) abuse.

(N/A) Sportspeople often misuse drugs like cocaine to enhance their physical performance,stamina,and alertness during competitions. Over time,the repeated use of these substances to gain a competitive edge leads to physiological and psychological dependence,resulting in addiction.

(A) The scientific name of the poppy plant is $Papaver$ $somniferum$.
It is the source of opium,from which opioids like morphine and heroin are derived.
$Cannabis$ $sativa$ and $Cannabis$ $indica$ are sources of cannabinoids.
$Atropa$ $belladona$ is a plant known for its hallucinogenic properties.

(B) Heroin, commonly known as smack, is chemically diacetylmorphine.
It is produced by the acetylation of morphine, which is extracted from the latex of the poppy plant, $Papaver \text{ somniferum}$.
Physically, it is a white, odorless, bitter, and crystalline compound.
It acts as a depressant and slows down body functions.
It is generally taken by snorting or injection.
Option $B$ is incorrect because it describes heroin as a 'colored' compound, whereas it is actually a 'white' crystalline compound.

(B) Bhang is a preparation made from the leaves and flowers of the $Cannabis$ $sativa$ plant.
It is a psychoactive substance that affects the central nervous system.
$Papaver$ $somniferum$ is the source of opium,while $Atropa$ $belladonna$ is a toxic plant known for its alkaloids like atropine.

(D) Cannabinoids are a group of chemicals which 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 plant are used in various combinations to produce $III$ (Charas), $V$ (Hashish), $VI$ (Marijuana), and $VII$ (Ganja). $I$ (Smack) is a derivative of morphine, $II$ (Cocaine) is obtained from $Erythroxylum \text{ } coca$, and $IV$ (Morphine) is extracted from the latex of the poppy plant $Papaver \text{ } somniferum$. Therefore, the correct combination is $III, V, VI, VII$.

(A) Athletes often misuse certain drugs to enhance their performance. Among the options provided,$Cocaine$ is a central nervous system stimulant that is frequently misused by athletes to increase alertness,reduce fatigue,and enhance physical performance. While other substances like $Morphine$,$Heroin$,and $Cannabinoids$ are also drugs of abuse,they are generally depressants or hallucinogens and do not serve the purpose of performance enhancement in the same way as stimulants like $Cocaine$ or anabolic steroids.

(A) The image on the left shows the poppy plant,$Papaver somniferum$,from which opium is obtained.
The image on the right shows the leaves of the cannabis plant,$Cannabis sativa$,from which cannabinoids like bhang,ganja,and charas are obtained.
Therefore,the correct sequence is Opium and Bhang.

(A) Cannabinoids are a group of chemicals that interact with cannabinoid receptors present principally in the brain. They do not interact with receptors in the gastrointestinal tract. They are known for their effects on the cardiovascular system of the body and are generally taken by inhalation and oral ingestion. Therefore,the statement that they interact with receptors in the gastrointestinal tract is incorrect.

(C) Morphine is a potent opioid analgesic derived from the poppy plant,$Papaver$ $somniferum$. It is widely used in clinical settings as a sedative and painkiller for patients who have undergone surgery,as it effectively suppresses pain signals in the central nervous system.

(B) Cocaine is a stimulant drug derived from the plant $Erythroxylum$ \text{ coca}.
It acts by interfering with the transport of the neurotransmitter dopamine in the synaptic cleft.
By blocking the reuptake of dopamine, it leads to an accumulation of dopamine in the synapse, which causes a potent stimulating action on the central nervous system, producing a sense of euphoria and increased energy.

(B) 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 its intake.
The characteristic symptoms of withdrawal syndrome include anxiety $(II)$,tremors $(III)$,nausea $(IV)$,and sweating $(VI)$.
Anemia $(I)$ and cancer $(V)$ are chronic health conditions and are not symptoms of withdrawal syndrome.
Therefore,the correct combination is $II, III, IV, VI$.

(A) Liver cirrhosis is a chronic condition characterized by the replacement of healthy liver tissue with scar tissue,which prevents the liver from functioning properly.
Chronic alcohol consumption is a leading cause of liver cirrhosis.
Alcohol is metabolized in the liver,and excessive intake leads to inflammation,cell death,and eventually fibrosis (scarring) of the liver tissue.
Therefore,the correct option is $A$.

(C) $Erythroxylum$ $coca$ is a plant species native to the Andean region of South America. It is the primary source of the alkaloid cocaine, which is a stimulant drug.

(D) An overdose of drugs,particularly opioids,barbiturates,or other central nervous system depressants,can lead to severe physiological impairment.
Respiratory failure is a primary cause of death because these substances suppress the respiratory centers in the brainstem.
Cerebral hemorrhage and heart failure can also occur due to extreme fluctuations in blood pressure and physiological stress caused by the drug overdose.
Therefore,all these factors contribute to the risk of coma and death.

(A) The correct matching is as follows:
$P$. Opioids are typically taken by oral ingestion or injection $(P-I)$.
$Q$. Cannabinoids are known to be taken by inhalation and oral ingestion $(Q-II)$.
$R$. Cocaine is a stimulant that is typically snorted, i.e., taken through the nasal route $(R-III)$.
Therefore, the correct sequence is $(P-I), (Q-II), (R-III)$.

(B) The correct matching is:
- $A$. Heroin: It is a depressant that slows down body functions $(A-II)$.
- $B$. Marijuana: It is well-known for its significant effect on the cardiovascular system $(B-I)$.
- $C$. Cocaine: It interferes with the transport of the neurotransmitter dopamine $(C-IV)$.
- $D$. Morphine: It is a potent sedative and painkiller $(D-III)$.
Therefore, the correct sequence is $A-II, B-I, C-IV, D-III$, which corresponds to option $B$.

(C) The correct answer is $A-III, B-IV, C-I, D-II$.
$A$. Cocaine is obtained from the plant $Erythroxylum$ $coca$ and acts as a stimulant on the $CNS$.
$B$. Heroin is formed by the acetylation of morphine, which is obtained from the plant $Papaver$ $somniferum$.
$C$. Morphine is obtained from $Papaver$ $somniferum$ and is an effective sedative and painkiller used in surgery.
$D$. Marijuana is obtained from $Cannabis$ $sativa$ and produces hallucinogenic effects, affecting the cardiovascular system of the body.

(A) Heroin,also known as smack,is a white,odorless,bitter crystalline compound.
Chemically,it is diacetylmorphine.
It is synthesized by the acetylation of morphine,which is extracted from the latex of the poppy plant ($Papaver$ $somniferum$).
Since the chemical nature of heroin is directly defined by the process of acetylation of morphine,the reason correctly explains the assertion.

(B) The provided image shows the flowering branch of the plant $Datura$ (commonly known as Jimsonweed or Thorn apple).
$Datura$ is well-known for its hallucinogenic properties due to the presence of alkaloids like scopolamine and hyoscyamine.
In the context of the $NCERT$ biology curriculum,this specific diagram is used to illustrate plants with hallucinogenic properties.
Therefore,the correct option is $B$.

(B) 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 $Cannabis$ $sativa$. The flower tops, leaves, and the resin of the $Cannabis$ plant are used in various combinations to produce marijuana, hashish, charas, and ganja.
$Datura$ and $LSD$ (Lysergic acid diethylamide) are hallucinogens, not cannabinoids. $Datura$ is a plant-based hallucinogen, while $LSD$ is a synthetic drug derived from fungi.

(D) The correct matches are as follows:
$1$. $\text{LSD}$ (Lysergic acid diethylamide) is derived from the fungus $\text{Claviceps purpurea}$. Thus,$A \longrightarrow iv$.
$2$. $\text{Morphine}$ is an opioid extracted from the latex of the poppy plant,$\text{Papaver somniferum}$. Thus,$B \longrightarrow iii$.
$3$. $\text{Charas}$ is a cannabinoid obtained from the plant $\text{Cannabis sativa}$. Thus,$C \longrightarrow i$.
$4$. $\text{Cocaine}$ is an alkaloid obtained from the coca plant,$\text{Erythroxylum coca}$. Thus,$D \longrightarrow ii$.
Therefore,the correct sequence is $A \longrightarrow iv, B \longrightarrow iii, C \longrightarrow i, D \longrightarrow ii$.

(D) The primary reasons that motivate youngsters towards the use of drugs and alcohol include curiosity,a need for adventure and excitement,and the desire for experimentation. These factors,often influenced by peer pressure and social environments,lead individuals to try these substances for the first time. Therefore,all the given options are correct.

(B) Opioids are drugs that bind to specific opioid receptors present in our central nervous system $(CNS)$ and gastrointestinal tract $(GIT)$.
These receptors are responsible for the analgesic and sedative effects of opioids.
Therefore,the correct answer is the gastrointestinal tract.

(C) Intravenous drug abuse involves the use of shared needles and syringes.
When needles are shared among multiple users,blood-borne pathogens can be transmitted directly from one person to another.
$AIDS$ (Acquired Immuno Deficiency Syndrome) is caused by the $HIV$ virus,and Hepatitis $B$ is caused by the Hepatitis $B$ virus.
Both of these viruses are transmitted through the exchange of infected blood,making intravenous drug users a high-risk group for these infections.

(D) Cocaine is a stimulant drug derived from the leaves of the coca plant, $Erythroxylum$ $\text{coca}$.
It is commonly referred to by various street names, including $Coke$ and $Crack$.
$Smack$ is a common street name for heroin, not cocaine.
Therefore, both $B$ and $C$ are correct names for cocaine.

(B) Morphine is a potent analgesic and cough suppressant alkaloid. It is extracted from the latex of the unripe capsules of the poppy plant, $Papaver$ $somniferum$. Therefore, the correct option is $B$.

(D) Alcohol abuse,especially during adolescence,leads to severe long-term health consequences.
$1$. Chronic alcohol consumption causes damage to the liver,leading to $liver \text{ } cirrhosis$,where healthy liver tissue is replaced by scar tissue.
$2$. It also causes inflammation of the pancreas,known as $pancreatitis$.
$3$. Alcohol affects the central nervous system,leading to a loss of coordination and balance.
$4$. Options $A$ and $C$ are associated with anabolic steroid abuse,while option $B$ is associated with drug abuse (like hallucinogens).

(B) The correct matches are as follows:
$i$. Heroin: It is a depressant that affects the gastrointestinal tract $(d)$.
$ii$. Marijuana: It is known to affect the cardiovascular system $(b)$.
$iii$. Cocaine: It is a stimulant that interferes with the transport of the neurotransmitter dopamine,leading to its increase in the synapse $(a)$.
$iv$. Alcohol: Chronic consumption of alcohol is a major cause of liver cirrhosis $(c)$.
Therefore,the correct matching is $i-d, ii-b, iii-a, iv-c$.
