What effect does inhalant use typically have on speech?

Inhalant use is known to produce a range of psychoactive effects, primarily due to the chemicals that are inhaled. One of the most prominent effects of inhalant use is that it can lead to slurred speech. This occurs because inhalants depress the central nervous system, similar to the effects of alcohol. The ingestion of these substances can disrupt the normal coordination and functioning of speech-related muscles, resulting in difficulties articulating words clearly.

Individuals under the influence of inhalants may also experience impairments in cognitive functions, which can contribute to the challenges in forming coherent thoughts and communicating effectively. As such, slurred speech is a common and observable side effect that denotes the extent of the neurological impact that inhalants have on the user. In contrast, the other options suggest improvements in clarity and articulation, which do not align with the intoxication effects caused by inhalants.
