Final answer:
A person using ecstasy and consuming a large volume of fluids risks water intoxication, which dilutes electrolytes in the blood. This can result in severe health complications, including seizures and death. MDMA exacerbates risks by causing fluid retention and excess sweating.
Step-by-step explanation:
A person who uses the drug ecstasy at a crowded party begins to feel too hot and drinks lots of fluids is at risk for water intoxication, also known as hyponatremia. This condition occurs when a person consumes a large volume of water in a short amount of time, which can dilute electrolytes like sodium in the blood to dangerously low levels. Symptoms of water intoxication can include nausea, headache, confusion, and in severe cases, seizures, coma, or even death. MDMA, the active ingredient in ecstasy, can exacerbate this by causing the body to retain fluids and stimulating excessive sweating, which further disrupts the body's electrolyte balance.
Additionally, MDMA use can lead to dehydration due to excessive sweating, especially when combined with the hot environment of a party and physical exertion like dancing. Dehydration itself can be a medical emergency if not treated promptly. It is important for individuals to be mindful of their fluid intake and to replenish electrolytes when necessary to avoid both dehydration and water intoxication.
