What general indicator suggests stimulant influence?

Stimulants, such as cocaine or amphetamines, are known to increase energy levels and elevate mood, often leading to a state of euphoria. This heightened sense of well-being is a hallmark sign of stimulant influence, as users often experience an intense feeling of happiness or excitement. It is important to recognize this as a key indicator because the effects of stimulants can drastically alter a person's emotional state and behavior, leading them to engage in activities they might not otherwise consider.

In contrast, sluggish behavior, extreme fatigue, and heightened senses are not typically associated with stimulant use. Sluggish behavior and extreme fatigue are more indicative of depressant influence, as these substances work to slow down bodily functions. Heightened senses can occur but are more nuanced; while stimulants may heighten alertness, the overall emotional state when one is on stimulants primarily leans toward euphoria. This makes euphoria a clear and direct indicator of stimulant influence.
