Misfire Cannabis -nitrous oxide

We were two friends who smoked a little and thought of strengthening the high with nitrous oxide. I took first without any problems, my friend then took, but in the wrong way. He then starts vomiting around the apartment and coughs badly, he lied down and could barely breathe, suffocating by himself he was fainting from not being able to breathe. This lasts for two hours of constant coughing and light fainting. In the meantime, I needed to make sure he stayed awake, breathing, as he often stopped. Knowing that he could die from this, I called an ambulance that takes him to a hospital. I am then told by the ambulance staff that an incredible number of brain cells died from this and that he might never recover fully. The scariest thing was the knowledge that if he could die.
