What are some examples of schedule 5 controlled drugs?

• A. Codeine and morphine in low strength preparations e.g. cough syrup and anti-diarrhoea medication.
• B. Diazepam
• C. Ketamine
• D. Methadone

Answer: (A)

Schedule 5 drugs are the least tightly controlled among the controlled substances, consisting of preparations that contain small amounts of narcotics and can be sold with restrictions rather than by prescription in many systems. The example given—codeine and morphine in low-strength preparations such as cough syrups and anti-diarrheal medications—fits this category because these products use only tiny amounts of opioids to provide mild relief, allowing access with safeguards rather than a full prescription.

Diazepam, ketamine, and methadone carry higher levels of control due to greater potential for misuse and dependence. Diazepam is a benzodiazepine with a Schedule 4 status, while ketamine and methadone are more tightly regulated (often Schedule 2 in many places).
