Bupe Heroin on top

Hi Guys, i think i never saw this answered.
My question is, does smoking heroin on top of subutex reduces the bup half-life?
For example (that was not teh case), someone takes 4 mgs, the sub level would be 4mg in the first day, 2.25 in the second, 1m59 inb the thiurdm does this change? If i take 4 mgs of sub, 24 hours after i will still not be in heroin wd, but if i take heroim 2/3 hours after the bup, does the wd came sooner, or will come like the heroin was never taken?

From what I get from what you said..

It would be as if the heroin were never taken since the bupe would be in your system and whatever is left on that second day would stay even if there were some open receptors to let heroin attach to. However, if all receptors are saturated with bupe, heroin wouldn't have a strong enough affinity to displace the bupe. Making the heroin useless.

Maybe I don't understand what you mean, but from how I read it.. that's my answer.
