Which substance is commonly associated with increased anxiety and restlessness?

• A. Opiates
• B. Cocaine
• C. Alcohol
• D. Barbiturates

Answer: (B)

Cocaine is widely recognized as a stimulant that can lead to heightened levels of anxiety and restlessness. When ingested, it increases the levels of certain neurotransmitters, particularly dopamine, which can create a sense of euphoria and heightened energy. However, it can also lead to negative psychological effects, including elevated anxiety levels, paranoia, and restlessness, especially as the drug's effects wear off. These symptoms are often exacerbated by the physiological impact of the stimulant, which keeps the body in a heightened state of alertness. In contrast, the other substances listed generally have different effects. Opiates are primarily depressants and tend to induce relaxation and pain relief. Alcohol can initially create a sense of euphoria and relaxation, yet in higher quantities or during withdrawal, it may also lead to anxiety, but it is not primarily associated with restlessness in the same way that stimulants like cocaine are. Barbiturates, as sedatives, typically induce relaxation and calmness, making them less likely to be associated with increased anxiety and restlessness.
