Plastic bags are a common household item, but they can pose a serious risk of suffocation, especially in cases of suicide or homicide. While it may seem that oxygen would be able to enter a bag with a large enough opening, the act of breathing can pull the plastic into the mouth, blocking airflow. This risk is heightened in cases of panic or gasping for air. The presence of a plastic bag over the head at a death scene can be valuable to pathologists in determining the cause of death, particularly in cases of complex suicides, where other methods like drug intake are involved.

What You'll Learn
Plastic bag suffocation is a rare cause of death
Plastic bags can be dangerous, and they can cause suffocation in certain situations. However, it is important to note that plastic bag suffocation is not a common cause of death. In fact, it has been described as "rare".
When a body is found at the scene of death with a plastic bag in place, it can be challenging for pathologists to determine the exact cause of death. This is because plastic bag suffocation may leave little to no signs of asphyxiation during an autopsy. The absence of visible signs can make it difficult to distinguish between accidental, suicidal, or homicidal causes.
Plastic bag suffocation can occur accidentally, especially in small children who play with shopping bags and adolescents who engage in substance abuse. It is also a known risk factor for sexual asphyxia, primarily among adult males. Additionally, infants, frail adults, or those who are terminally ill are at higher risk of homicidal suffocation.
Suicidal suffocation using plastic bags has been reported, sometimes in combination with other methods such as self-poisoning or inhalation of volatile compounds. These cases often present unique challenges for pathologists and investigators due to the complexity of determining the exact cause and manner of death.
While plastic bags can pose a suffocation risk in certain circumstances, it is important to emphasize that such cases are rare. The majority of people, especially adults without serious disabilities, are unlikely to accidentally suffocate from a plastic bag.

Autopsy may show poor or no signs of asphyxia
Asphyxial death by plastic bag suffocation is an unusual but effective method of suicide. It is often combined with the assumption of CNS depressants, such as codeine overdose, to guarantee death.
Plastic bag suffocation may leave poor or no signs of asphyxia at autopsy. This is because death occurs very rapidly due to a cardio-inhibitory mechanism rather than a hypoxic one. This makes the diagnosis of complex suicides involving plastic bag suffocation very challenging for forensic pathologists.
In cases where the plastic bag is still in place at the scene, the pathologist may be able to determine that suffocation was the cause of death. However, in three reported cases, the local pathologist could not give a cause of death when the initial autopsy was performed. This is because plastic bags could be accidentally placed over the head, used to inhale volatile substances, or even used with homicidal intent.
To accurately determine the cause and manner of death in complex suicides involving plastic bag suffocation, a comprehensive toxicological analysis, careful scene examination, and histological studies are crucial. This information, combined with a thorough comparative analysis of existing literature, can help forensic pathologists reconstruct and interpret the events leading to death.

Plastic bags are used in suicides and homicides
Plastic bags can be used as a method of suicide and homicide. While suffocation by plastic bag is not common, it can be challenging for pathologists to determine the cause of death when a body is found with a plastic bag in situ. In such cases, the presence of a plastic bag can be diagnostically valuable.
Plastic bags have been used in suicides since at least the 1990s, often in conjunction with the inhalation of volatile substances such as chloroform, ether, or propane. In some cases, individuals with terminal illnesses have used plastic bags as a method of "self-deliverance", as it is relatively non-violent and plastic bags are readily available. The book "Final Exit: The Practicalities of Self-deliverance and Assisted Suicide for the Dying" by Derek Humphry is credited with increasing the popularity of this method, particularly among older individuals. Suicide kits containing plastic bags and inert gases such as helium or nitrogen have also been promoted by euthanasia organisations, though the sale of such kits has been prohibited in some places due to ethical concerns.
Plastic bags have also been implicated in homicides, though such cases are rare and not well-studied. Between 2008 and 2021 in Medellín, Colombia, 96 out of 17,703 homicides (0.54%) were due to suffocation with plastic bags. The victims were predominantly young men between the ages of 15 and 27, with 74.4% of the cases involving unidentified corpses.
The use of plastic bags in suicides and homicides can have significant implications for forensic investigations. In some cases, the presence of a plastic bag at the scene may be the only indication of foul play. Additionally, the use of inert gases such as nitrogen in suicide bags can make the direct cause of death difficult to trace, as there is currently no test to detect asphyxiation by nitrogen.

Plastic bag suffocation can be accidental
Plastic bags are not a common cause of suffocation, but they can be dangerous, especially in certain scenarios. Accidental suffocation from plastic bags can occur in several ways. Firstly, small children playing with plastic bags may accidentally place them over their heads, restricting airflow and leading to suffocation. This is more likely to occur if the bag gets stuck or if the child has a disability.
Secondly, adolescents who engage in substance abuse, particularly solvent abuse, may accidentally suffocate if they inhale volatile substances from a plastic bag. This can happen if they are unaware of the dangers or if they underestimate the amount of substance they are inhaling. Additionally, in a state of intoxication, adolescents may be more likely to take risks, such as placing a plastic bag over their head, which can lead to accidental suffocation.
Another form of accidental death from plastic bag asphyxia is sexual asphyxia, primarily seen among adult males. This involves restricting oxygen to the brain during sexual activity to intensify the orgasm, which can result in accidental death if not performed safely.
Furthermore, infants or adults who are frail, terminally ill, or unable to struggle can be victims of homicide by plastic bag asphyxiation. This occurs when a perpetrator intentionally places a plastic bag over the victim's head, blocking their airway and causing suffocation.
It is important to note that even in cases of apparent suicide by plastic bag suffocation, there may be underlying factors or mental health issues that contributed to the decision. Therefore, while it may be ruled a suicide, there are often complex factors at play that align with accidental death.
To conclude, while plastic bag suffocation is not a common cause of death, it can occur accidentally in various scenarios, especially when certain risk factors are present. It is important to be aware of the dangers and to seek help if struggling with mental health or substance abuse issues.

Plastic bags can be used with other methods in suicides
Plastic bag suffocation is often combined with self-poisoning by inhalation of volatile compounds or pharmacological substances at poisoning dosage. For example, ether inhalation and propane inhalation have been documented as methods used in conjunction with plastic bags. In one case, a victim dumped ether on a towel, placed it inside a plastic bag, and put his head inside. The death was ruled a suicide by asphyxiation.
Plastic bag suffocation is also combined with drug intake, such as codeine overdose, to induce a deep reduction in respiratory rate. This combination of methods can make diagnosis in forensic pathology very challenging, as poor or no signs of asphyxia may be present at autopsy.
Another method that can be used with plastic bags is the use of inert gases, such as helium or nitrogen, which are lighter or less dense than air. This method can make the direct cause of death difficult to trace if the bag and gas canister are removed before investigation. Suicide bags, also known as exit bags, are large plastic bags with a drawcord used to die by suicide through inert gas asphyxiation.

Frequently asked questions
Yes, plastic bags can cause suffocation, but it is not common. Death occurs rapidly due to a cardio-inhibitory mechanism, leaving poor or no signs of asphyxia at autopsy.
Plastic bags can restrict airflow if they block the mouth or nose, or if the bag opening is closed off, preventing oxygen from entering and carbon dioxide from escaping.
Plastic bag suffocation is often intentional, used as a method of suicide, homicide, or sexual asphyxia. However, accidental deaths have also been reported, especially among small children playing with bags and adolescents misusing solvents.
