Tranquillisers are included in which class?

• A. Class B
• B. Class A
• C. Class C
• D. Not controlled

Answer: (C)

Tranquillisers are benzodiazepines such as diazepam and temazepam, and in the UK they are controlled drugs under the Misuse of Drugs Act. They are placed in Class C because they have a significant potential for dependence and harm, but their risk profile is not as high as the drugs in Class A or the mid-range risks typically associated with Class B. They have legitimate medical uses when prescribed, which is why they’re controlled rather than not controlled at all. Possession without a prescription is illegal, and offences can be made for supply or intent to supply.

So, this grouping reflects a balance: they’re controlled drugs due to misuse risk, but not the highest-risk category.
