how do laughing gas(nitrous oxide), make us laugh? for how long does it effect?

Answer 1

Nitrous oxide is a dissociative drug that can cause analgesia, euphoria, dizziness, flanging of sound, and slight hallucinations.
Nitrous oxide can be habit-forming because of its short-lived effect (generally from 1 - 5 minutes in recreational doses) and ease of access. Death can result if it is inhaled in such a way that not enough oxygen is breathed in. While the pure gas is not toxic, long-term use in very large quantities has been associated with dangerous symptoms similar to vitamin B12 deficiency: anemia due to reduced hemopoiesis, neuropathy, tinnitus, and numbness in extremities. Pregnant women should not use nitrous oxide as chronic use is teratogenic and foetotoxic. It should also be noted that long term recreational use may lead to Olney's lesions, a form of brain damage.

Answer 2

Nitrous oxide, N2O, is commonly called laughing gas.

However, it has nothing to do with humor, but it is an anesthetic, a gaseous drug which partly suppresses the nervous system. With the nervous system working slower, thinking is reduced, and rational inhibitions are partly reduced. That can easily result in laughing, if a person emotionally would like to be a little silly. In addition there is probably some euphoric effect, and perhaps some novel feelings vaguely resembling dizziness. That too might incline a person with reduced inhibitions to laugh.

It doesn't make everyone laugh.It gets used as a surgical anesthetic sometimes, and the subjects are as likely to calmly say incoherent things as to laugh.

Nitrous oxide is also used as a means to increase power output of internal combustion engines found in automobiles. It is introduced into the intake manifold and acts as an oxidizer which allows more fuel to be burned.

Answer 4

The actual mechanism of action of N2O is still unknown (it appears that there are quite a few different mechanisms at work)! However, it's been observed that N2O depresses almost all forms of sensation - especially hearing, touch and pain, and that it seems to disinhibit some emotional centers in the brain. The ability to concentrate or perform intelligent acts is only minimally affected, as is memory.

Answer 5

Nitrous oxide,dinitrogen oxide or dinitrogen monoxide, is a chemical compound with chemical formula N2O. Under room conditions, it is a colorless non-flammable gas, with a pleasant, slightly sweet odor. It is used in surgery and dentistry for its anaesthetic and analgesic effects, where it is commonly known as laughing gas due to the euphoric effects of inhaling it.



In medicine
In the 1800s, nitrous oxide was used by dentists and surgeons for its mild analgesic properties. Today, nitrous oxide is used in dental procedures to provide inhalation sedation and reduce patient anxiety. In small doses in a medical or dental setting, nitrous oxide is very safe, because the nitrous oxide is mixed with a sufficient amount of oxygen using a regulator valve. However, extended, heavy use of inhaled nitrous oxide has been associated with Olney's Lesions in rats, though it is not necessarily possible to extrapolate it to humans.

Nitrous oxide is a weak general anesthetic, and so is generally not used alone in general anaesthesia. However, it has a very low short-term toxicity and is an excellent analgesic. In addition, its lower solubility in blood means it has a very rapid onset and offset, so a 50/50 mixture of nitrous oxide and oxygen ("gas and air", supplied under the trade name Entonox) is commonly used for pain relief during childbirth, for dental procedures, and in emergency medicine.

In general anesthesia it is used as a carrier gas in a 2:1 ratio with oxygen for more powerful general anaesthetic agents such as sevoflurane or desflurane. It has a MAC of 105% and a blood:gas partition coefficient of 0.46. Less than 0.004% is metabolised in humans.


[edit] Recreational use
Since the earliest uses of nitrous oxide for medical or dental purposes, it has also been used recreationally, because it causes euphoria, slight hallucinations and, in some cases, potential aphrodisiac effects. Only a small number of recreational users (such as dental office workers or medical gas technicians) have legal access to pure nitrous oxide canisters that are intended for medical or dental use. Most recreational users obtain nitrous oxide from compressed gas containers which use nitrous oxide as a propellant for whipped cream, from small canisters of nitrous oxide which are intended for use with whipped cream dispensers, or from automotive nitrous systems. Automotive nitrous available to the public has trace amounts of sulphuric compounds added to prevent recreational use. The sulphur additives only act to make the taste and odor of the gas unpleasant, and does not diminish the effects of the gas in any manner (although such sulfur compounds are harmful to the lungs when inhaled).

Users typically inflate a balloon or plastic bag with nitrous oxide and inhale the gas for its effects. While inhaling nitrous oxide, users face the risk of injury or death from anoxia. Nitrous oxide gas inhaled directly from a metal canister or tank, or by the use of a homemade mask over their mouth directly connected to a canister or tank, presents significantly more dangerous effects.

Nitrous oxide can be habit-forming because of its short-lived effect (generally from 1 - 5 minutes in recreational doses) and ease of access. Death can result if it is inhaled in such a way that not enough oxygen is breathed in. While the pure gas is not toxic, long-term use in very large quantities has been associated with dangerous symptoms similar to vitamin B12 deficiency: anemia due to reduced hemopoiesis, neuropathy, tinnitus, and numbness in extremities. Pregnant women should not use nitrous oxide as chronic use is teratogenic and foetotoxic. It should also be noted that long term recreational use may lead to Olney's lesions, a form of brain damage.

Answer 6

it causes a spasm which makes you laugh, it can be in effect up until the supply of gas runs out or you die

Answer 7

It cuts off oxygen to your brain....That's why some people have siezures from it. Cutting off the oxygen to your brain KILLS brain cells, and soon everything becomes funny when your a droolin.................
