A man presenting with visual hallucinations, confusion, and restlessness is most likely experiencing effects from which substance?

1. Alcohol

2. Marijuana

3. Cocaine

4. Barbiturates

The correct answer is: Cocaine

The symptoms described—visual hallucinations, confusion, and restlessness—are commonly associated with stimulant substances, particularly cocaine. Cocaine use can lead to a range of psychological effects, including heightened alertness, euphoria, and increased energy levels, often accompanied by anxiety and agitation. In some cases, heavy or prolonged use can cause serious psychological disturbances such as hallucinations and paranoia. Visual hallucinations are less commonly associated with alcohol, marijuana, and barbiturates. While alcohol can lead to confusion and restlessness, its effects are typically characterized by sedation rather than hallucinations. Marijuana may produce altered perceptions but is not typically linked to the severe confusion and restlessness seen in this scenario. Barbiturates, being central nervous system depressants, would generally cause sedation and confusion, not the stimulation and heightened perception that can accompany cocaine use. Thus, the combination of visual hallucinations, confusion, and restlessness aligns most closely with the effects of cocaine.
