My boyfriend had an overdose of meth this morning. he ate two to three grams. he was shaking and sweating i took him to hospital and they monitored his heart for a few hours. he still is hallucinating and has a bit of the shakes. what can do at home?

Hydrating him well because up to 50% is excreted unchanged in the urine. The half life varies and the CNS effects will last to the next day.

As you can see, the effects of meth are quite profound, and acutely, can be deadly, but long-term useage can be truly disastrous. Once stabilized, would start a drug rehabilitation program immediately. Otherwise, drug abuse can be catastrophic for all involved.
