inhaler

The term primarily evokes a clinical or emergency medical context, specifically associated with respiratory distress and the immediate relief of asthma or COPD. It carries a connotation of necessity and life-saving utility, often implying a chronic condition that requires a portable tool for stability.

When referring to a person, the term is less common and often appears in technical medical reports or specific descriptions of substance use. In these instances, it shifts from describing a tool to describing an agent of action, though the medical device remains the dominant usage in everyday English.
