What is a common source of inhalants?

Volatile solvents are considered a common source of inhalants because they include a variety of household and industrial products that can be inhaled for their psychoactive effects. These solvents typically have low boiling points which allow them to easily vaporize, making it easy for individuals to inhale the fumes. Common examples of volatile solvents include substances found in glue, paint thinners, gasoline, and cleaning products.

In contrast, while vape pens can deliver substances for inhalation, they primarily function by vaporizing liquids specifically designed for that purpose, rather than representing a broad class of inhalants. Natural foods generally do not contain chemicals that would induce the kind of psychoactive effects associated with inhalants. Pharmaceuticals, although they can be misused in certain forms, are not classified under inhalants in the traditional sense, as they are primarily intended for medical use rather than recreational inhalation. Thus, volatile solvents stand out as a key category responsible for inhalant use and abuse, making this the correct answer.
