I'm a little shaken right now, I think I just saw someone overdose.
Wow, how do you know they were overdosing?
I saw them injecting something in the bathroom and then they started having spasms and passed out.
If you see someone who is unresponsive then you should get help immediately. Every second matters in a life or death scenario and the sooner they can get help, the better chance they have at surviving.
I ran out of there as fast as I could because I was so freaked out.
Make sure you call 911 and report what you saw as soon as possible. This person needs medical attention right away. If that was you overdosing, you would want someone to call for help!
