What is one of the relaxation effects caused by nicotine?

Decreases respiration rate
Increases sensation
Calms CNS response
Enhances muscle strength

The correct answer is: Calms CNS response

Nicotine is known to have a complex interaction with the central nervous system (CNS). One of the relaxation effects attributed to nicotine is its ability to calm the CNS response. This calming effect occurs because nicotine can temporarily enhance the release of certain neurotransmitters, such as dopamine and serotonin, which contribute to a sensation of pleasure and relaxation. When an individual consumes nicotine, it activates receptors in the brain that can help to alleviate feelings of anxiety or stress, providing a sense of calmness. On the other hand, while nicotine can have various physiological effects on the body, it does not significantly decrease respiration rate; in fact, it can lead to an increase in heart rate and blood pressure. Enhanced sensation is also not a primary effect of nicotine, as its stimulant properties often lead to heightened alertness rather than relaxation. Lastly, nicotine does not enhance muscle strength; rather, its effects are more focused on mood and CNS modulation.
