Question

Jessica Mabbayad · Accepted Answer

Final Answer : B, Explanation :  LSD (lysergic acid diethylamide) is known for causing enhanced visual perceptions, among other sensory distortions, without necessarily impairing consciousness or causing sedation. The symptoms described, including poor coordination and palpitations, along with the relatively short duration of effects, are consistent with the effects of LSD. Alcohol, heroin, and barbiturates typically cause more pronounced sedation or impairment of consciousness than described.
