Morphine vs heroin strength

[sober4david]

So I read online that heroin is 3 times stronger then morphine my question is a 100 mg morphine pill would be one equal to One tenth of 33 percent pure heroin I snort my heroin and eat my morphine but it seems to me that one tenth of michigan quality heroin is way stronger then a hundred milligram morphine does that mean that my heroin is stronger then 30 percent or are the two just not comparable

I wanted I add how I came up with those number if a hundred milligram morphine would be a tenth of a gram of morphine so I figured it should equal a .33 of a tenth of heroin or a full tenth of 33 percent purity

I did not factor in the bioavailalty thank you I'm I correct in assuming good heroin in michigan I'm right between and Chicago is 30 percent or Is there no to know really

Street level H can vary so widely in potency from region to region even from dealer to dealer so there is no correct way to assume or calculate the strength of each bag of H to Morph imo...

heroin and morphine are basically the same drug (Heroin is actually an old brand name for 'diacetylmorphine'), but they have slightly different Pharmacokinetics...
Heroin. One reason H gives you a euphoria, whereas morphine does not because H crosses the Blood Brain Barrier much more readily, thus gets to the receptors in the brain much quicker...
