Inhalants (Sniffing)

Inhalant abuse refers to the deliberate inhalation of chemical vapours from common household or industrial products to achieve a brief intoxicating effect. In Nigeria, the most commonly abused inhalants include rubber cement (cobbler's glue), petrol (gasoline), paint thinner, correction fluid (Tipp-Ex), aerosol sprays, and lighter fluid. What makes inhalants uniquely dangerous is their accessibility and cost: most of these substances are cheap, legal to purchase, and found in homes, schools, and workshops. This makes inhalant abuse the primary form of substance use among children aged 8–14 who are too young or too poor to access other drugs — particularly street children and children in economically marginalised communities.

The mechanism of inhalant toxicity is brutal and immediate. When inhaled, these chemicals — primarily hydrocarbons, halogenated hydrocarbons, and nitrous oxide — displace oxygen from the alveoli of the lungs and blood. The brief "high" is literally oxygen deprivation to the brain, similar to asphyxiation. Within seconds, the brain and heart are deprived of oxygen. The heart is particularly vulnerable: these chemicals cause cardiac arrhythmia by sensitising the heart muscle to adrenaline. Any sudden physical exertion or fright — like being startled while using — can trigger "Sudden Sniffing Death Syndrome," a fatal cardiac arrhythmia. This can occur on the very first use, in a previously completely healthy individual.

For survivors of repeated inhalant abuse, the neurological consequences are catastrophic. The myelin sheaths that insulate nerve fibres — the biological equivalent of wire insulation — are dissolved by the organic solvents in inhalants. This causes a progressive demyelination of the central and peripheral nervous system, resulting in loss of coordination, speech impairment, hearing and vision loss, cognitive decline, and eventually a condition resembling severe multiple sclerosis. The brain damage accumulates with each exposure and, once extensive, is irreversible.

The social context of inhalant abuse in Nigeria demands community and parental attention. Groups of young boys — often school-aged — sharing a plastic bag of glue or a petrol-soaked cloth is not unusual in certain urban areas. The social dynamics that normalise this behaviour make individual intervention difficult. Education targeting both children and adults who interact with them (parents, teachers, market traders who sell glue) is essential for prevention.
