hydrocodone, dihydrocodeine, hydrocodeine

[liberty boy]

What is the difference between these three? Do they all contain parecetamol?

[Paregoric Kid]

some do contain tylenol, some don't, read the label or do a pill ID to find out if a specific one does or does not have acetaminophen (paracetamol).
hydrocodone is stronger than dihydrocodeine. hydrocodeine doesn't exist, only dihydrocodeine and hydrocodone.
