I would think so because she was on them for so long. People have withdraws even when they don't abuse them if they have taken them for a long period of time because our bodies get used to it being there.
She was taking 8 norco and 4 somas every day. She had to display withdrawals of some kind right?
Yes, I do believe she is using because she did not display any symptoms at all for the 2 weeks she said she was not taking them. No symptoms? I do not believe it.
It's possible if she wasn't taking a huge number of them. Why are you asking? Do you suspect she may still be using?
