What type of dependence can barbiturates create?

Barbiturates can lead to both physical and psychological dependence due to their effects on the central nervous system. Physical dependence occurs when the body becomes accustomed to the presence of the drug, resulting in withdrawal symptoms when the drug is not taken. This is often seen with barbiturates because they can depress brain activity, leading to the body's adaptation to their effects over time.

Psychological dependence develops when a person feels a compulsion to use the drug for its mood-altering effects, often using it to cope with stress, anxiety, or other emotional issues. This dual dependence makes barbiturates particularly concerning, as individuals may struggle to stop using them not only due to withdrawal symptoms but also due to their ingrained psychological habits and beliefs surrounding the drug's benefits.

In contrast, the other options do not capture the full scope of dependence that can arise from barbiturate use, making it clear that the correct choice accurately reflects the complexities of the issue.
