SWIM may have pure heroin but needs to turn it into morphine so he doesn't show up positive on heroin drug test. Hydrolyzing the ester bonds of heroin would make it into morphine. SWIM theorized that you can break the ester bond by dissolving the heroin in dilute NaOH and heat and reflux it. Would this work? How dilute is dilute and how long and at what temperature do you reflux at? SWIM'd really appreciate any advice from someone with some chemistry experience
