I don't really understand the point of something like this. It took me 5 minutes or so to actually think of an "out of left field" reason why someone would ever want to do this. To clarify, PH of solution plays a role in the rate of the degradation, but yes, if you leave Heroin in solution for an extended period of time, it will revert to Morphine. I'm going to close this, as it's not in line with Harm Reduction. It's also kind of stupid honestly.
