A suicide method is any means by which a person purposely kills himself or herself. Examples of methods that have been used to commit suicide are listed below. Though individuals with suicidal feelings may consider these methods, most eventually do not act on them.^[1]

[edit] Beheading

A device capable of beheading the user (a guillotine for instance) can be used for suicidal purposes.^[2][3] Results of the cutting action of the device depend mainly on what nerves and blood veins the device cuts. The more arteries supplying blood to the brain are cut, the sooner the death comes. Cutting nerves which transfer control signals for vital body functions, like breathing, is also irrecoverable and lethal.^{[citation needed]}

[edit] Bleeding

Exsanguination is a method of death which is caused by blood loss. It is usually the result of damage inflicted on arteries. The carotid, radial, ulnar or femoral arteries may be targeted.

[edit] Cutting wrists

This entails cutting through the wrists with the aim of tearing open the radial artery and may damage the tendons, ulnar and median nerves which control the muscles of the hand, which can result in temporary or permanent reduction in sensory and motor ability.^[4] Wrist slitting is usually not fatal and it is thought that of all suicide attempts using this method, only 1% succeed.^{[citation needed]}

[edit] Cutting the carotid artery

Cutting through the throat is one method of exsanguination. Damage is inflicted to the carotid artery which carries blood to the brain, and it takes no longer than a few minutes to lose enough blood for death to occur,^{[citation needed]} although death could also be caused by blood clogging the trachea. People who do this often cut the recurrent laryngeal nerve, the nerve that goes up to the voicebox and larynx, and lose their voices.

It was also practiced as a ritual suicide method in Japan called jigai, by noble women for the same purposes as seppuku was used by men.^{[citation needed]}

[edit] Drowning

Suicide by drowning is the act of deliberately submerging oneself in water or other liquid and staying there long enough to prevent breathing and deprive the brain of oxygen. Due to the body's natural tendency to come up for air, drowning attempts often involve a heavy object, to circumvent this reflex. If the drowning is stopped before death, oxygen deprivation can cause brain damage.

[edit] Suffocation

Suicide by suffocation is the act of inhibiting one's ability to breathe, causing asphyxia. This may involve a plastic bag tightly sealed over the head, or confinement in an enclosed space without oxygen. These attempts usually involve using depressants to make the user pass out, preventing any escape instinct. The method common in terminally ill or sincere "want-to-die" candidates is to use a gas, such as nitrogen or helium.^{[citation needed]}

[edit] Electrocution

Suicide by electrocution involves using a lethal electric shock to kill oneself. A high enough voltage can overcome the high resistance of the skin and pass a sizeable current through the body. A large alternating current through the body can seriously disrupt nerve signals and can cause the heart to go into fibrillation.

[edit] Explosives

Suicide by explosives involves setting off high explosives (HE) in close proximity to the body. A sufficient quantity of high explosives would cause death instantaneously by destroying the body so thoroughly that life would end instantly - indeed, before the nervous system could register the explosion. Shattered organs, broken bones and internal bleeding from the blast wave would be likely causes of death where insufficient HE was used. The use of low-powered or home-made explosives would be likely to cause severe burns rather than immediate death.^{[citation needed]}

When explosives are detonated with the intent of also harming others in close proximity it is commonly known as a suicide bombing.

[edit] Hanging

Main article: Hanging

Hanging is the prevalent means of suicide in pre-industrial societies and is still more common in rural rather than urban areas.^[5]

The traditional death penalty of hanging by gallows consists of a rope tied to a fixed object (i.e. the gallows), with one end tied into a hangman's noose and placed around the neck. The person falls through the release of a trap door (or leaps from a height, in the case of suicide), death is instantaneous due to breaking of the neck. In instances where the suicidal person breaks fall and is cut down by a bystander before the person suffocates, spinal injury and complete quadriplegia is an expected possibility. If the neck is not broken, asphyxiation due to the obstructed trachea may cause loss of consciousness and ultimately lead to death.^{[citation needed]}

[edit] Vehicular impact

Jumping in front of a fast-moving vehicle, especially a large one, such as a truck or train, can prove fatal. A classic example of suicide involves one tying oneself to railroad tracks in order to be run over by an oncoming train. This may be traumatizing to the driver of the vehicle. Failure would likely result in massive body damage including: fractures, brain damage, organ bruising, long term to permanent disability^{[citation needed]}

Jumping in front of an underground train is a common form of suicide in London. Where a deep drainage pit is present, this halves the likelihood of mortality. Separation of the passengers from the track by means of a partition with sliding-doors is being introduced in some stations but this is expensive.^[6]

[edit] Jumping

See also: Defenestration

Jumping from a great height can shatter organs and tissues. If a person jumps from a tall bridge into water, the person may die by impact rather than by drowning. Such jumping off the Golden Gate Bridge, of which there have been 1,300 incidents between 1937 and 2006, were depicted in the documentary film The Bridge.

The 70 m (225 ft) plunge from the Golden Gate Bridge has proven to be fatal in 98% of cases. The jumper would hit the water at 120 km/h (about 75 mph).^[7] Most die of internal bleeding due to broken ribs which pierce the heart, lungs, liver or spleen. Survivors, who generally have hit the water feet-first, have often had their femurs shattered.^[8]

Authorities have tried to prevent jumping suicides by building fences or other barriers in potential areas, such as high towers and bridges. In some areas authorities have also installed telephones which link directly to suicide prevention hot lines.

[edit] Poisoning

Suicide can be committed by using fast-acting poisons, or substances which are known for their high levels of toxicity to humans. For example, most of the people of Jonestown, in northwestern Guyana, died when the leader of a religious sect organised a mass suicide by drinking a cocktail of diazepam and cyanide in 1978.^[9] Sufficient doses of some plants like the belladonna family, castor beans, and others, are also toxic.

[edit] Drug overdosing

Suicide by pharmaceuticals ("overdosing") is a method which involves taking medication in doses greater than the indicated levels, or in a combination which will enhance each drug's effect. Due to the unpredictability of dosing requirements, death is uncertain, and an attempt may leave a person alive but with severe organ damage (which may prove eventually fatal itself). Drugs taken orally may also be vomited back out before being absorbed.

Analgesic overdose attempts are among the most common^[10] due to easy availability of over-the-counter substances. Overdosing may also be performed by mixing medications in a cocktail with one another, or with alcohol or illegal drugs.

This method may leave confusion over whether the death was a suicide or accidental, especially when alcohol or other judgment-impairing substances are also involved and no suicide note was left behind.

[edit] Carbon monoxide poisoning

Main article: Carbon monoxide poisoning

A particular type of poisoning involves inhalation of high levels of carbon monoxide. Death usually occurs through hypoxia. In most cases carbon monoxide (CO) is used because it is easily available as a product of incomplete combustion; for example it may be released by cars and some types of heaters.

Carbon monoxide is a colorless and odorless gas, so its presence cannot be detected by sight or smell. It is harmful to humans since the CO molecules attach themselves to hemoglobin in the blood, displacing oxygen molecules and progressively lowering the body's oxygenation, eventually resulting in death.

In the past, before air-quality regulations and catalytic converters, suicide by carbon monoxide poisoning would often be achieved by running a car's engine in a closed space such as a garage, or by redirecting a running car's exhaust back inside the cabin with a hose. Motor car exhaust may have contained up to 25% carbon monoxide. However, catalytic converters can eliminate over 99% of carbon monoxide produced.^[11]

The incidence of suicide by carbon monoxide poisoning through burning charcoal, such as a barbecue in a sealed room, appears to have risen. This has been referred by some as "death by hibachi".^[12]

[edit] Detergent-related suicide

Detergent-related suicide involves mixing household chemicals to produce hydrogen sulfide or other poisonous gasses.^[13]

[edit] Self-immolation

Self-immolation is suicide by immolation (fire). It has been used as a protest tactic, most famously by Thich Quang Duc in 1963 to protest the South Vietnamese government; and by Malachi Ritscher in 2006 to protest the United States' involvement in the Iraq war.

[edit] Seppuku

Main article: Seppuku

Seppuku (colloquially "harakiri") is a Japanese ritual method of suicide, practised mostly in the medieval era, though some isolated cases appear in modern times. For example, Yukio Mishima committed seppuku in 1970 after a failed coup d'etat intended to restore full power to the Japanese Emperor.

Unlike other methods of suicide, this was regarded as a way of preserving one's honor. The ritual is part of bushido, the code of the Samurai.

Dressed ceremonially, with his sword placed in front of him and sometimes seated on special cloth, the warrior would prepare for death by writing a death poem. With a selected attendant (kaishakunin, his second) standing by, he would open his kimono, take up his wakizashi (short sword), fan, or a tanto (knife) and plunge it into his abdomen, making first a left-to-right cut and then a second slightly upward stroke. On the second stroke, the kaishakunin would perform daki-kubi, when the warrior is all but decapitated, leaving a slight band of flesh attaching the head to the body, so as to not let the head fall off the body and roll on the floor/ground; which was considered dishonorable in feudal Japan.

[edit] Shooting

Shooting oneself in the head is one of the most common means of suicide for men in societies where firearms are widely available.^{[citation needed]} Within nations with strict firearms control laws, it is generally confined to policemen and soldiers as a suicide method.^{[citation needed]}

[edit] Apocarteresis (suicide by starvation)

Main article: Starvation

Starvation has been used by Hindu, Jain and Buddhist monks as a ritual method of suicide.

[edit] Suicide attack

Main article: Suicide attack

A suicide attack is an attack in which the attacker (attacker being either an individual or a group) intends to kill others and intends to die in the process of doing so. In a suicide attack in the strict sense the attacker dies by the attack itself, for example in an explosion or crash caused by the attacker. The term is sometimes loosely applied to an incident in which the intention of the attacker is not clear though he is almost sure to die by the defence or retaliation of the attacked party. This can also be referred to as murder/suicide.

Such attacks are typically motivated by religious or political ideologies and have been carried out using numerous methods. For example, attackers might attach explosives directly to their bodies before detonating themselves close to their target, or they may use car bombs or other machinery to cause maximum damage (e.g. Japanese kamikaze pilots during World War II).

Islamic extremist terrorists have engaged in suicide attacks numerous times in the Arab-Israeli conflict, and also against the West at other times. Perpetrators believe the gains to others, or to a religious, political or moral cause, outweigh their personal loss and/or that they will be rewarded in the afterlife.

Additionally, teenage students (most often in the United States of America and recently in Finland) have committed several notable suicide attacks in recent years, in the form of school shooting massacres. Often, these suicide attacks involve guns or homemade bombs brought into high schools or college campuses. After the attack, the perpetrator will commit suicide before being captured by police.

[edit] Indirect suicide

Indirect suicide is the act of setting out on an obviously fatal course without directly committing the act upon oneself. Indirect suicide is differentiated from legally defined suicide by the fact that the actor does not pull the metaphorical (or literal) trigger. Examples of indirect suicide include a soldier enlisting in the army with the express intention and expectation of getting killed in combat. Another example would be provoking an armed officer into using lethal force against them. This is generally called suicide by cop.
