80mg morphine daily. is this safe?

Morphine dosage: That depends. If you have been on opiates - lortab, percocet, ect. I may be perfectly safe as long as it's given in divided doses - say three times a day where it totals 80mg. For someone who never takes opiates, to take 80 mg of morphine all at once could kill them by supressing respiration. This effect is amplified by alcohol, benzos and medicines like soma (carisoprodol).
