A 17-year-old girl is brought to the emergency department by her friends who were at a party with her and found her unconscious in the bathroom. They admit that alcohol was present at the party. The patient's blood pressure is 118/78 mm Hg, pulse is 40/min, respiratory rate is 16/min, and temperature is 36.7°C (98.1°F). On physical examination, she is unresponsive to verbal commands but does respond to noxious stimuli. Her pupils are pinpoint and her mucous membranes are moist. Her heart is bradycardic without murmurs, and her respiratory rate is slowed but clear to auscultation. What is the most likely cause of her symptoms?
