Is poppers a stimulant or depressant?

Poppers, which are typically amyl nitrite or similar compounds, are not classified as traditional stimulants or depressants. Instead, they act as vasodilators, causing blood vessels to widen, which can lead to a brief feeling of euphoria or lightheadedness. While they may produce stimulating effects, such as increased heart rate, they don't fit neatly into either category. Their effects are short-lived and primarily related to their physiological impact rather than a direct stimulant or depressant action.
