Clean and sober houses run by professionals have people use drugs, drink and overdose. The people renting the rooms are doing good. This was a result of unfortunate decisions made by two people. It is actually pretty common for people to share prescribed narcotics. The best thing to do is store your narcotics in a safe place others do not have access to, don't tell them you take the meds, if they find out about them and try to get some the answer is always no.
