Hello, welcome to HCM. Bath salts can cause extreme paranoia, hallucinations
, delusions, rapid heart rate
, chest pain
and suicidal thoughts. The nasal bleeding
is due to local irritation of blood vessels in the nose. She should just lie down straight on her back and avoid blowing her nose much. It will heal by itself. Just keep her away from such stuff in future and maintain her hydration by giving her lot of fluids. Wish her good health.
