What is an indicator that someone may be under the influence of hallucinogens?

One of the hallmarks of hallucinogen use is the impact these substances have on perception, cognition, and motor functions. Difficulty speaking can be a direct result of altered thought processes and impaired cognitive function, which are common effects of hallucinogens. Individuals experiencing hallucinations or altered states of consciousness may struggle to articulate their thoughts clearly, making coherent speech difficult.

While uncontrolled laughter might occasionally occur with hallucinogen use, it does not consistently indicate influence and can vary widely among individuals. Heightened alertness is typically associated with stimulants rather than hallucinogens, while slow reflexes may more accurately reflect depressant influences rather than the psychedelic effects of hallucinogens. Therefore, the presence of speech difficulties stands out as a more reliable indicator of hallucinogen use.
