Which statement about cocaine-induced delusional disorder is false?

The statement that cocaine-induced delusional disorder may not appear until 21 days after the last use of cocaine is inaccurate. In fact, symptoms of cocaine-induced delusional disorder typically arise during or shortly after cocaine use, as the substance affects the brain's neurotransmitter systems. Delusions can manifest during active use, withdrawal, or even after the drug has been cleared from the system, but they are more commonly seen within a shorter timeframe following cessation.

This is contrasted with the statements regarding visual distortions, the duration of delusions, and the association with tactile hallucinations, which are accurate. Cocaine use can lead to various perceptual disturbances, including visual distortions and tactile hallucinations, which are sensations of physical sensation without external stimuli (commonly felt as bugs crawling on or under the skin). Additionally, delusions seen in this context often resolve fairly quickly, typically within a month, but there can be exceptions based on individual circumstances and the severity of the disorder. Understanding these dynamics is crucial for recognizing the signs of cocaine-induced delusional disorder and managing treatment effectively.
