What is a common side effect of habit-forming medications?

Habit-forming medications are substances that can lead to physiological or psychological dependence when used over a prolonged period. Individuals taking these medications may find themselves needing to consume larger doses to achieve the same effect, often resulting in a cycle of increased use. This phenomenon occurs because the body starts to adapt to the presence of the drug, making it difficult to function normally without it. Consequently, the potential for dependency is a significant concern with these types of medications, as it can lead to withdrawal symptoms and challenges in discontinuing use.

The other choices reflect potential effects or benefits of medications but do not directly characterize the inherent risk associated with habit-forming medications. Improvements in mood and increased energy can be effects of certain medications but do not address the specific risks linked to dependence. Similarly, lowered blood pressure may occur with some medications but is not a universal side effect and does not relate to the addictive nature of these substances.
