Chemicals that can be legally purchased and used for non-recreational purposes, including gasoline and airplane glue, are categorized as which?

• A. Depressants/Sedative-hypnotics
• B. Stimulants
• C. Hallucinogens/Dissociatives
• D. Inhalants

Answer: (D)

Inhalants are chemicals that people can buy legally and use for legitimate purposes, yet some inhale their vapors to get high. This category includes everyday products like gasoline and airplane glue, which release fumes that affect the brain when inhaled. The key distinction is the route of administration and the fact that these substances are common, legally available items used for non-recreational reasons but misused for their intoxicating effects. This sets them apart from depressants, stimulants, or hallucinogens, which are defined by the specific brain effects they produce rather than by how commonly they can be purchased.
