As I mentioned, 37 states in the U.S. have good Samaritan or 911 drug immunity laws and they also sometimes are for low-level possession, but often will include supervision violations as well. There is evidence when they did a survey in Washington state, the vast majority—88% of people who used opioids—indicated they would be more likely to call 911 during a future overdose, knowing it was there. But there is the issue of making sure that people are aware of the good Samaritan law, and I think that's where we need to make sure it happens.
