The correct option is B Stimulants
Drugs are chemical substances which have physical and psychological effects when administered into an organism’s body.
Certain drugs are used as stimulants, analgesics (pain killers), hallucinogens, sedatives, tranquilisers and performance enhancers. While their immediate effects might seem beneficial, prolonged abuse of drugs leads to various chronic diseases such as permanent damage to the nervous system, psychosis (loss of contact with reality), damage to major internal organs such as heart, liver and kidneys, etc.
Amphetamines are synthetic drugs which act as strong stimulants. They produce a feeling of self-confidence, alertness, well-being and increased ability to concentrate and perform. Thus, these are also known as pep pills.
Opiate narcotics like morphine, heroin, etc are drugs derived from opium (obtained from the unripe pods of the opium poppy plant) and are used as analgesics or pain killers. These drugs dull down the senses of the nervous system and relieve the body of pain. They act as depressants.
Sedatives are drugs which slow down the activities of the central nervous system, calm down anxiety and cause drowsiness. Barbiturates and benzodiazepines are commonly used sedatives.
Hallucinogens like LSD or lysergic acid diethylamide are responsible for hallucinations.
