Question

What do methamphetamine, ecstasy, and cocaine have in common?

A. They slow body functions and calm neural activity
B. They depress neural functioning and reduce pain
C. They distort perceptions and evoke sensations without sensory input
D. They excite neural activity and arouse body functions
E. They relax the body, lead to disinhibition, and relax the central nervous system

Answer 1

Methamphetamine, ecstasy, and cocaine are all stimulants that excite neural activity and stimulate body functions, significantly increasing dopamine neurotransmission and leading to effects such as euphoria and heightened alertness.

Step-by-step explanation:

Methamphetamine, ecstasy, and cocaine share the common characteristic of being stimulants that excite neural activity and arouse body functions. These substances are known to increase dopamine neurotransmission, leading to heightened reward sensations and potential abuse. Unlike depressants, which slow down brain activity and are subsequently known as 'downers', these stimulants increase alertness, induce feelings of euphoria, and raise physical energy levels. The effects of stimulants can include increased heart rate, elevated blood pressure, and a euphoric 'high'.

Repeated use of these stimulants can result in negative consequences such as mood disorders, cognitive problems, feelings of anxiety, hallucinations, and paranoia. Despite their differences, all these drugs share their ability to substantially alter brain chemistry and stimulant the central nervous system. The correct answer to the question is D. They excite neural activity and arouse body functions.
