Which of the following is considered a type of controlled substance?

Benzodiazepines are classified as controlled substances due to their potential for abuse and dependence. They are a category of central nervous system (CNS) depressants that are commonly prescribed for anxiety, insomnia, and other related conditions. The regulation of benzodiazepines is important to ensure they are used safely and appropriately, as misuse can lead to serious health risks, including addiction and overdose.

Controlled substances are categorized based on their potential for abuse, medical use, and safety. Benzodiazepines fall under this category because they can cause significant physiological and psychological effects, which makes their distribution and prescription subject to strict regulatory oversight.

In contrast, over-the-counter medications, vitamins, and supplements do not typically fall under the same regulations as controlled substances. They are generally considered to have a lower risk of abuse and are available without a prescription, which sets them apart from benzodiazepines and other controlled substances. Cannabis, while regulated, has different classifications depending on the jurisdiction, and in many areas, it may not be classified in the same way as benzodiazepines.
