Verified step by step guidance

Understand the classification of drugs: Depressants are substances that reduce the activity of the central nervous system, leading to effects such as relaxation, drowsiness, and decreased inhibition.

Identify the drugs listed: Alcohol, Valium, and Morphine are all classified as depressants. Alcohol is a common depressant, Valium is a benzodiazepine used for its calming effects, and Morphine is an opioid used for pain relief.

Recognize the exception: Cocaine is not a depressant. It is classified as a stimulant, which means it increases the activity of the central nervous system, leading to increased energy and alertness.

Differentiate between stimulants and depressants: Stimulants like cocaine have the opposite effect of depressants, as they enhance brain activity rather than suppress it.

Conclude that the drug John has not tried, based on the classification, is Cocaine, as it does not fit the category of depressants.
