Method plastic bag combined with carbon dioxide (CO2) gas

[GerMann]

Suicide by plastic bag suffocation combined with the mixture of citric acid and baking soda in an adolescent.

We describe a case of suicidal asphyxiation using a plastic bag combined with carbon dioxide (CO2) gas. A 20-year-old male, whose head was covered with a plastic bag, was found dead in his room. In the plastic bag, there were two glass-made cups containing liquid-like substance. Through crime scene investigation by police staffs, a bottle of citric acid and a box of baking soda were also discovered in his room. The forensic autopsy revealed that there were neither lesions nor injuries in all of the organs. Moreover, any drugs and poisons could not be detected in blood samples. Based on autopsy findings and crime scene investigation, the cause of death was diagnosed as acute asphyxia due to CO2 intoxication by the mixture of citric acid with baking soda in the plastic bag. To the best of our knowledge, there are no medical literatures describing plastic bag suffocation combined with CO2 gas generated from citric acid and baking soda, which has been widely distributed as suicidal means through websites. This case report promotes forensic pathologists and medical coroners to emphasize that the Internet has a crucial role on a source of suicidal information or a promoter of suicide all over the world.

i got vinegar and baking soda...combining them also produces co2 gas...how do i use this method? Whats the apparatus...how are glasses used? What happened to his survival instict

Not possible while you are conscious. CO2 is the main reason that causes suffocation.

There were earlier CO2 suicides, and people were conscious at the start of CO2 inhaling.

Once tried to take a few breaths from a big plastic bag with evaporated dry ice inside just to know what would it be. Couldn't take more than two breaths: besides suffocation (as said) I felt slight burning in my nasopharynx and my heartbeat increased quickly.

It may be that time needed to lose consciousness in (pure)CO2-exit bag is the same as in helium/N2-exit bag, but this time would be extremely painful with CO2.

I have heard of suicides by plastic bag without drugs and without inert gas. Possibly, some people do not react as strongly to high CO2 levels as others.

This case report promotes forensic pathologists and medical coroners to emphasize that the Internet has a crucial role on a source of suicidal information or a promoter of suicide all over the world.

Let me just say that their colleagues in psychiatry in some cases are de facto promoters of forced suffering all over the world.
