What is a common misconception about caffeine?

Caffeine is often misunderstood in terms of its effects on the body and mind. One of the prevalent misconceptions is that it does not lead to addiction. In reality, caffeine is classified as a psychoactive substance that affects the central nervous system and has the potential to cause physical dependence in some individuals.

When consumed regularly, caffeine can create a tolerance effect, where increased amounts are needed to achieve the same stimulant effects. Additionally, individuals may experience withdrawal symptoms such as headaches, fatigue, and irritability when they attempt to reduce or stop their caffeine intake. This dependence is what aligns caffeine with the concept of addiction, despite it being legal and widely accepted in society.

The other choices present misconceptions as well. While caffeine is indeed a legal drug and does affect the central nervous system, believing it does not or only causes positive effects overlooks the complexities of how it interacts with the body and the potential negative consequences it can have on health and daily functioning.
