What is a common effect of CNS stimulants?

1. Increased relaxation

2. Decreased alertness

3. Increased euphoria and excitation

4. Blurred vision and disorientation

The correct answer is: Increased euphoria and excitation

CNS stimulants, such as amphetamines and cocaine, primarily enhance the activity of certain neurotransmitters in the brain, particularly dopamine and norepinephrine. This increase in neurotransmitter levels leads to heightened levels of euphoria and excitation, making individuals feel more alert, energetic, and in a better mood. These substances can create a sense of well-being and increase focus, which is why the sensation of increased euphoria and excitation is a hallmark effect of CNS stimulants. The other options reflect effects that are not typically associated with CNS stimulants. Increased relaxation is more characteristic of CNS depressants, while decreased alertness would not be expected from a stimulant, which primarily aims to heighten awareness and energy levels. Blurred vision and disorientation can sometimes occur as side effects or in cases of overdose, but they are not defining or common effects of CNS stimulants.
