What are some general indicators of hallucinogen influence?

Hallucinations are a primary indicator of hallucinogen influence because these substances are specifically characterized by their ability to alter perception and trigger sensory experiences that do not reflect reality. Individuals under the influence of hallucinogens may see, hear, or feel things that are not present, which can significantly affect their awareness and interpretation of their surroundings. This distinct effect is a hallmark of hallucinogen use, differentiating it from the influence of many other substances, which might cause different types of physiological or psychological alterations without inducing actual hallucinations. Recognizing hallucinations is crucial for identifying substance influence and ensuring appropriate response and care for the individuals affected.
