Can you please tell me about the effects of being high on crack like hallucinations?

Possibly: Crack can cause any number of horrific effects like visual and auditory hallucinations. If someone abuses crack long enough then they can become challenging to distinguish from individuals who struggle with bipolar disorder or schizophrenia due to the damage that the drug can do to mood regulation and thought processes.

Cocaine: Crack is stimulant, so hyperarousal & agitation & changes in pupil size with increased metabolism are common.
