What does "Never Use Alone" mean?

If someone is going to use drugs, they should never be alone. Someone needs to be able to call 911 or administer Naloxone in case of emergency. Unfortunately, sometimes, people may not have someone to be a sober buddy and still choose to consume illicit substances. In these cases, people can call a hotline like Never Use Alone and have them remain on the line during the critical window where an overdose could occur.
