I just found a guy passed out

In my work parking lot. He’s in his early twenties at most. The hotel next door is a homeless shelter. He was passed out and had a box with different coloured pills on the ground beside him. He was breathing but I couldn’t wake him. I called 911. A worker from the hotel came over and was able to get the young guy to wake up and got him speaking. I told him I’m on the phone with 911 and they’re sending an ambulance. He started crying and begged me to cancel the ambulance. The worker said he’d take him back to the hotel and keep an eye on him and call 911 if needed. I was told they’d hold him for up to 3 days and make him detox.

I hope I made the right decision to cancel ambulance

This is my second time finding someone in this situation. The last one was only about 14 years old
