Yes, usually what happens is they throw up and they are so drunk they don't wake up, they aspirate the vomit and basically drown in it. But alcohol is a toxin, and a depressant, it can cause alcohol poisoning if too much is consumed which can damage internal organs and cause the heart to stop beating in some circumstances.
YES if it is too much alcohol too fast it is called alcohol poisoning. Also they could choke if they throw up while passed out. They need to be watched and any sign of distress you need to take them to the ER or call 911.
Yes a person can die when they pass out from drinking, even if it is the first time. Their body can try to rid itself of the poisoning alcohol by vomiting, and if the person is on their back, the vomit can be aspirated into the lungs and cause death. Do not leave your friend alone. Move them onto their side if they roll onto their back. If they consumed massive quantities of alcohol, call 911 because permanent damage can result from even one time of overdrinking.
Please tell whoever did this not to forget because they almost died . My best friend died the same way alcohol poisoning and threw up in His throat and then inhaled it laying On his back asleep by 730 he was cold it's terrible we still have dreams About it but we still love him.
