Inhalant abuse commonly involves which substances?

• A. CNS depressants - may cause death
• B. Glue, toluene, nitrous oxide
• C. Dermatitis around mouth or nostrils is apparent
• D. Signs of acute intoxication - transient, brief euphoria + loss of consciousness

Answer: (B)

Inhalants are volatile substances that people inhale for a quick high, often found in everyday products. The classic examples are adhesives like glue (which contain toluene), and gases such as nitrous oxide (used in whipped-cream canisters). These substances are readily available and produce rapid CNS effects when inhaled.

This option is the best because it lists concrete inhalant substances rather than general categories or symptoms. The other statements describe broad effects or signs of use (CNS depressants in general, dermatitis from exposure, or acute intoxication symptoms) but do not name the substances actually involved in inhalant abuse.
