How sad that your daughter is using her little girl to get back at you. That is doing your granddaughter harm. You know that, yes? I really feel for you.
To answer your questions; no, wellbutrin does not make a test come up positive for opiates; opiates make a drug test come up positive for opiates. suboxone does not show up positve for opiates, they need to actually test for suboxone to find that.
And when you use suboxone, you cannot get high on other opiates. it doesnt harm her when she does this, she just wont get high. the only harm that can come from doing this is that the addict will try desperately to get high and take more and more and even though they dont feel high, they can still overdose from taking too many opiates. but usually, when the addict realizes that they are not getting high, they just give up trying. you need to get the sub out of your system in order to get high again. and because of the long half life of suboxone, this can take days.
i continue to pray for you and your little "ruthie" and your daughter. i hope that she comes to a place of wanting to help herself soon.
p.s. will she be able to continue taking sub in jail?
