ok I'm going to tell you all why I don't use coke anymore...
I only used for about 2 to 3 years off and on occasionaly for fun with friends until it got bad at one point which wasn't even too bad but about 3 to 4 times a week, more or less.
Anywho... in those 2 to 3 years I have seen two people OD on coke. One had to go to the hospital and one didn't. (the one who didn't, didn't "need" to go because I was too coked out to take his ass and had already been through this shit before a few months prior).
So anyway... the first person I saw OD was only 3 lines into the night. Me and two friends went in on an ounce of decent coke from Mexico. I live about 15 mins away. So we start out the night snorting average size lines about a pencil width (the skinny way if you laid a pencil down) wide. And about 3 to 4 inches long.
Anyhow... after his third line, he decides to sniff another two about the same size when everyone is busy talking and he drops on the floor shaking his ass off going into seizures with convulsions and all and he bounces around the floor foaming at the mouth and spitting blood on himself and then just stops moving abrubtly and doesn't move an inch. Starts turning blue etc... we roll him over on his side and start calling 911 and out of nowhere he jumps up, eyes wide open and punches the person trying to tilt his head at the time in the face and runs at lightning speed around the room punching things, knocking shit over, breaking lamps, etc... and then runs room to room doing the same sort of deal. Then he sort of slows down and just stares at everyone, asking what the fuck just happened.
We try to explain he just OD'd on coke and had a seizure but he was all loopy and didn't believe us because he didn't remember any of it. He started taking off his clothes and asking for water (which we gave him) and saying he felt like he was on fire and his heart hurt.
So I drove him to the ER at that point at like 3 am coked out of my head.
I guess they shot him with some sort of downer and released him a little while later.
Next friend....
Same thing happened, only he had been snorting decent lines all day long from around 3pm until about 12am when we met up with him to do some. We were drunk and I was drunk and on mushrooms when I snorted my first line with him and walked away to chat with some people, and bam next thing you know.. he's flopping around on the floor halfway screaming, halfway gagging and holding his chest. His face looked like it hurt more than I can ever imagine, but since I'd seen it before and was now feeling the coke numbing my face and shit, I was cool about and calmed the rest of the room down. I explained what was probably going to happen next (him running around full of adrenaline breaking shit) and we held his ass down while he jerked around and kicked a table over, then tried to jump up and run for it.
He slowly came out of it and didn't remember anything that happened and thought we were lying when we said he took too much and had a seizure. So we gave him some valium and finished off a quarter of coke between three people that all watched what just happend. After that night I'm kinda over coke. I slip up now and then when I'm drunk and do it here and there but I learned from others that it doesn't take much to OD. It might not kill you, but you'll end up with a shirt and floor full of blood and snot and a bunch of broken shit, not to mention a sore heart.
If that ever happens wait it out... if the person stops moving and doesn't come out of it within 10 mins or so.. get them to a hospital.
The doctors told my first friend he had an adema? I think they call it that... when too much blood gets trapped in your brain and it swells up real quick. You go into a seizure and your heart stops while your body recovers. If your heart doesn't start up again within a second or so... you die. Pretty simple. People who OD on coke usually have a seizure first and then die in the middle of it.
Good luck with the coke.
