sorry to hear about what you are going through with your bf, sorry to say but those 2 little wax paper baggies taped shut are commonly what drug dealers sell heroin in. If you want to know for sure take one of the baggies and open it and smell it, if it has a medicine bottle // vitamin type of smell it is heroin. Also if it is not pure white but an off-white//tan or brown powder you also know it is heroin.
Like people above me had said, that is usually what happens to most people who climb the "opiate ladder" . Same happened to me, was addicted to oxycontin and then moved onto heroin late in my addiction because it was cheaper and a stronger high.
