List I | List II | ||
| A | Heroin | I | Effect on cardiovascular system |

| D | Morphine | IV | Interfere with transport of dopamine |
Choose the correct answer from the options given below:
The correct match between List I and List II is:
A. Heroine - Slow down body function
Heroin, an opioid derived from morphine, is a potent narcotic. It slows down the body’s function by acting on the central nervous system, leading to drowsiness, decreased respiration, and a feeling of euphoria. This matches with the correct description in List II as it inhibits the normal functioning of the brain and the body.
B. Marijuana - Effect on cardiovascular system
Marijuana, also known as cannabis, affects the cardiovascular system by increasing heart rate and blood pressure immediately after consumption. Its active ingredient, THC, interacts with the brain’s cannabinoid receptors and can have both short-term and long-term cardiovascular effects, including an increased risk of heart attack in some individuals.
C. Cocaine - Interfere with transport of dopamine
Cocaine is a stimulant drug that interferes with the reuptake of dopamine, a neurotransmitter involved in mood regulation and pleasure. By blocking dopamine transporters, cocaine causes an accumulation of dopamine in the brain, leading to intense feelings of euphoria. This interference is the primary reason why cocaine is addictive.
D. Morphine - Painkiller, obtained from latex of poppy plant
Morphine is an opioid and a powerful painkiller that is derived from the latex of the opium poppy plant. It is commonly used in medical settings to manage severe pain, particularly after surgery or injury, due to its potent analgesic properties.
The correct option is (D): A-II, B-I, C-IV, D-III
Conclusion: Understanding the effects of these substances is critical, as they have significant physiological impacts. Heroin (A) slows down body function, marijuana (B) affects the cardiovascular system, cocaine (C) interferes with the dopamine transport, and morphine (D) is a potent painkiller obtained from the poppy plant. This question tests knowledge of drug classifications and their associated health risks.
