Diazepam (Valium)

Diazepam (brand name Valium) is a long-acting benzodiazepine prescribed medically for anxiety disorders, muscle spasms, alcohol withdrawal, and seizure management. It works by enhancing the effect of GABA — the brain's primary inhibitory neurotransmitter — producing sedation, anxiety reduction, and muscle relaxation. In Nigeria, diazepam tablets are widely available through informal pharmaceutical channels (patent medicine stores, roadside vendors) without prescription, making them easily accessible for recreational use and abuse.

The prevalence of diazepam abuse in Nigerian universities and social settings reflects a broader pattern of prescription drug misuse. Students use it to manage exam anxiety ("studying calmly"), to sleep after stimulant use, or to reduce social inhibition. Its relatively low immediate danger profile compared to opioids creates a false sense that it is a safe drug to use recreationally. This is a fatal misconception: benzodiazepine dependence develops faster than most users expect — within 4–6 weeks of daily use — and the withdrawal syndrome is one of the most medically dangerous of any substance.

Benzodiazepine withdrawal is particularly insidious because its severity is not proportional to the perceived intensity of the addiction. Someone who has been using diazepam at seemingly moderate doses for 2 months can experience life-threatening withdrawal seizures if they stop abruptly. The brain's GABA system — which has been artificially suppressed during the period of drug use — becomes severely hyperactive without the drug. This neurological hyperactivity can cause grand mal seizures, hallucinations (delirium tremens), dangerous cardiac arrhythmias, and in some cases death. This withdrawal syndrome can persist for months in a condition called Protracted Withdrawal Syndrome.

The combination of diazepam with alcohol or opioids (codeine, tramadol) is responsible for a significant proportion of drug-related deaths in Nigerian hospitals. Both combinations cause synergistic respiratory depression — each substance individually slows breathing, together they can stop it entirely. This combination is extremely common in recreational drug use patterns.
