After the use of some drug, a person develops episodes of rage in which he runs about and indiscriminately injures a person who is encountered in the way. He is probably an addict of
First, I should recall which drugs are known to cause aggressive behavior or rage. Common culprits in pharmacology include stimulants like amphetamines, cocaine, and maybe even some hallucinogens. Also, certain medications or substances of abuse can have side effects that include aggression.
The core concept here is understanding the side effects of various drugs of abuse. The question is testing knowledge on the behavioral and psychological effects of different substances.
Now, considering the options (though they aren't listed), the correct answer is likely a stimulant. Amphetamine, for example, can cause paranoia and aggressive behavior when used in excess. Cocaine is another possibility, leading to psychomotor agitation and irritability. Methamphetamine is known for causing violent outbursts during a "run" or binge.
Wait, but the question mentions "rage in which he runs about and indiscriminately injures a person who is encountered in the way." This sounds like a description of a "rage attack" or "rage episode," which is a known effect of amphetamine use. Amphetamines can cause a state called amphetamine psychosis, which includes symptoms like aggression, paranoia, and hallucinations.
So if the correct answer is Amphetamine, then the explanation would focus on its mechanism of action increasing dopamine and norepinephrine, leading to overstimulation of the central nervous system. Other options might include substances like cannabis, which typically causes relaxation rather than aggression, or opioids, which are more associated with euphoria and respiratory depression. Alcohol might cause aggression, but the question mentions a drug use scenario, and alcohol's effects are more about lowered inhibition rather than direct rage episodes.
The clinical pearl here is to remember that stimulants, especially amphetamines, are classic for causing aggressive behavior and psychosis. Students should note that the presentation of rage and violent behavior is a red flag for stimulant abuse.
**Core Concept**
The question examines the behavioral and psychological effects of drug abuse, specifically the link between stimulant use and aggressive outbursts. Amphetamines, as central nervous system (CNS) stimulants, increase dopamine and norepinephrine levels, leading to hyperactivity, paranoia, and rage in high doses.
**Why the Correct Answer is Right**
Amphetamine (the correct answer) causes excessive release of dopamine and norepinephrine, overstimulating the sympathetic nervous system and limbic system. This can trigger amphetamine psychosis, characterized by aggression, hallucinations, and impulsive violence. The "rage episodes" described align with its neurochemical effects, including disinhibition and heightened fight-or-flight responses.
**Why Each Wrong Option is Incorrect**
**Option A:** Cannabis typically causes sedation, altered perception, and anxiety but not rage attacks.
**Option B:** Opioids like heroin induce euphoria and respiratory depression, not aggressive behavior.
**Option C:** Alcohol may lower inhibitions but rarely causes indiscriminate violence without co-ingestion of other substances.
**Clinical Pearl / High-Yield Fact**
Amphetamines are a classic exam trap for causing aggression and psychosis. Remember: "Stimulants stimulate rage," while
