In 1986 I shared an apartment with a buddy from high school. Across the hall from our end apartment was a young couple with a little kid. The guy smoked pot all the time when he wasn't out working. Work for him was collecting aluminum scrap to take to the recycling center. His wife wasn't happy with their lifestyle and made that fact abundantly clear.
Since we shared a living room wall with their apartment, we could hear when they'd fight. One day his wife was at our door crying with her screaming baby in hand. It seems that her husband was locked in the bathroom and wouldn't answer her, and would one of us kick in the door?
I got a small screwdriver and went into their dump of an apartment and tried to get him to talk to me through the door. No joy. I popped the lock with the screwdriver and opened the door. He was on his back on the floor with his trousers around his ankles, flopping around like a landed fish. His needle and the rest of his works were on the floor around him.
It seems that he had sat down on the toilet and mixed up a speedball, then shot it into his femoral artery. What he didn't know was that his dope a little harder hitting than the pot he usually anesthetized himself with, and he stroked out. When I got to him, all the blood vessels in his eyes had burst, so the whites of his eyes were actually the "reds" of his eyes. I got his head tilted back to keep his airway open and screamed for someone to call 911.
I tried to get him to talk to me, and put a cold wet cloth on his forehead, but he gradually slowed down like a wind-up toy. In a few seconds he had no pulse at all, so I started CPR. After calling 911, his crying wife came in the very small bathroom with me to clean up his drugs to he wouldn't get arrested for possession.
When the paramedics arrived, they took over and ended up defibrillating him a few times, but got no response. A cop sat me down and told me, "Hey, he killed himself just like putting a gun in his mouth."
He died on the bathroom floor with his trousers around his ankles.
Not to be a sarcastic asshole, but I'm not commenting on whether any of this is right or wrong, I'm only sharing my observations.
