Final answer:
Cocaine is known to cause or exacerbate excited delirium, a state of intense agitation and distress.
Step-by-step explanation:
Cocaine is the drug among the provided options that can cause or worsen the condition known as excited delirium. Excited delirium is a state of extreme agitation, aggression, acute distress, and possible sudden death. Heroin, which is an opioid, generally has the opposite effect on the central nervous system, causing sedation rather than stimulation or delirium. Ketamine, while being a dissociative anesthetic that can cause hallucinations and altered perceptions, is not commonly known to induce excited delirium, especially when used in a controlled medical setting. Marijuana does not typically induce such extreme symptoms as those found in excited delirium.
