text: Depending on what state you live in.\n\nSome states have laws that can hold someone responsible for manslaughter if they furnished the illegal drug to the "victim".\n\nYou will need to contact your local prosecutor and find out the law where you live and see if the crime was committed.\n\nBut, if your friend died just because he was using drugs and not something furnished to him by the other party, that party can't be held responsible just because he happened to die at his home.\n\nSorry for your loss.
