Is it possible for a person to make themselves unconsious besides alcohol?

Answer 1

there's lots of ways. Tying a rope around your neck tightly will lead to unconsciousness, and probably death, many types of drugs can. Anything which severely intereferes with your brain's functioning can lead to unconsciousness. For example, a sharp blow to the head, a large loss of blood, suffocation/drowning, dehydration, severe burning, stroke, and so forth. Obviously, most of these are serious and can lead to death, but then can alcohol poisoning.
