How much morphine would be a toxic dose?

Im not sure, I take 1000mg per day, by IM, by mouth Immediate release and M-Eslon time released. I have taken up to 2000 mg and the only effect was no pain. It is a hard question because if you do not take morphine I believe 20mg IV could overdose or kill you.

It differs from person to person while one person like above but I think he or she means 100 and 200 mg because a gram of morphine is white a bit. can take a high amount of morphine somebody who hasn't taken any kind of opiate can have respitory failure with only a small amount. It depends on a thing called tolerance.
