When someone overdoses on drugs, the most important thing a friend can do is call 9-1-1. Unfortunately, because of the drug laws in many jurisdictions across the country, the friendships of hard drug-users are put through life-or-death tests when one friend overdoses.
Because of the potential for being arrested for using or possessing drugs, fellow drug users often fear calling 9-1-1 to report overdoses. This, in turn, results in needless and preventable overdose deaths. However, a majority of the states give individuals, even drug users, limited immunity for calling to report a drug overdose. Even if your state doesn't provide immunity, it is not guaranteed that you will face charges if you do the right thing and call 9-1-1.
In a majority of states, you will not be arrested if you report a drug overdose while in possession or high on drugs yourself. However, in most, if not all, jurisdictions, a person that supplies the drugs to a person that overdoses is likely to face more than just drug charges. As one Portland man discovered last year, he was sentenced to four years in prison for involuntary manslaughter after a friend overdosed on heroin that he provided.
