Sodium is crucial for maintaining fluid balance and nerve function. Toxins such as amphetamines and MDMA (Ecstasy) can lead to hyponatremia, a condition characterized by low sodium levels. This occurs because these substances can induce excessive water intake and impair the kidneys' ability to excrete water, leading to dilutional hyponatremia. On the other hand, some toxins may lead to hypernatremia by causing dehydration or impairing water intake.
