A couple of months ago, I overdosed on an illegal drug and called an ambulance. I was honest and told them what I took. Two cops came with them and while I was in the ambulance and also in the ER 20 minutes later, the cops and the paramedics entered my house, presumably to investigate it for drugs, but they did not have an official search warrant, and they didn't ask for permission. The paramedics took some of my legal supplements with them but never gave them back.
Were they allowed to do this?
