There is more that can happen though. Here is a list from WebMD:
- Trouble breathing
- Signs of a heart attack or stroke, such as chest pain or confusion

A methamphetamine overdose may result in a wide range of symptoms.[4][22] A moderate overdose of methamphetamine may induce symptoms such as: abnormal heart rhythm, confusion, difficult and/or painful urination, high or low blood pressure, high body temperature, over-active and/or over-responsive reflexes, muscle aches, severe agitation, rapid breathing, tremor, urinary hesitancy, and an inability to pass urine.[4][29] An extremely large overdose may produce symptoms such as adrenergic storm, methamphetamine psychosis, substantially reduced or no urine output, cardiogenic shock, bleeding in the brain, circulatory collapse, hyperpyrexia (i.e., dangerously high body temperature), pulmonary hypertension, kidney failure, rapid muscle breakdown, serotonin syndrome, and a form of stereotypy("tweaking").[sources 1] A methamphetamine overdose will likely also result in mild brain damagedue to dopaminergic and serotonergicneurotoxicity.[94][21] Death from methamphetamine poisoning is typically preceded by convulsions and coma.[22]
