Answer

Solution

Valium (diazepam) is a benzodiazepine, i.e. a sedative-tranquilliser.

⇒ It depresses the activity of the brain and produces calmness, relaxation and drowsiness; it is prescribed for anxiety and insomnia.

⇒ Hashish is a cannabinoid that alters perception; amphetamines are stimulants of the nervous system.

⇒ Morphine is an opioid used mainly as a powerful painkiller (analgesic) and sedative.

∴ The drug that depresses brain activity and gives calmness, relaxation and drowsiness is Valium.
