Food grade nitrous oxide is also not meant to be inhaled the bulbs commonly have industrial lubricants from their manufacturing process on and in them. Inhaling industrial-grade nitrous oxide is also dangerous, as it contains many impurities and is not intended for use on humans. Pregnant women should not use nitrous oxide recreationally, because chronic use is also teratogenic and foetotoxic. While the pure gas is not toxic, long-term use has been associated with vitamin B12 deficiency and its symptoms: anemia due to reduced hemopoiesis, neuropathy, tinnitus, and numbness in extremities. Death can result if it is inhaled in such a way that not enough oxygen is breathed in. Nitrous oxide can be habit-forming, mainly because of its short-lived effect (generally from 1–5 minutes in recreational doses) and ease of access. For those reasons, most recreational users will discharge the gas into a balloon or whipped cream dispenser before inhaling. Inhalation directly from a tank poses serious health risks, as it can cause frostbite since the gas is very cold when released. So part of safer use can be to inhale it while seated, because there is a decreased risk of injury from falling. Since nitrous oxide can cause dizziness, dissociation, and temporary loss of motor control, it is unsafe to inhale while standing up. In Australia and New Zealand, nitrous oxide bulbs are known as "nangs", possibly derived from the sound distortion perceived by consumers. This is necessary because nitrous oxide is very cold when it undergoes adiabatic decompression on exit from a canister inhalation directly from a tank is dangerous and can cause frostbite of the larynx and bronchi. The gas is then inhaled from the balloon or dispenser. Recreational users generally use 8 gram containers of nitrous oxide "whippets", which they use to fill balloons or whipped cream dispensers. Current status ĢO whippets (above) and cracker (below)-can be used for recreational purposes There were no adverse effects reported in the more than one hundred individuals surveyed. They either held a breath of NĢO or rebreathed the gas. Although a few, more sophisticated users employed nitrous oxide-oxygen mixes with elaborate equipment, most users used balloons or plastic bags. Contact was made with a "mystical-religious" group that used the gas to accelerate arriving at their transcendental-meditative state of choice. At a recent rock festival, nitrous oxide was widely sold for 25 cents a balloon. Reports were received from people who used the gas contained in aerosol cans both of food and non-food products. There also were those who work in restaurants who used the NĢO stored in tanks for the preparation of whip cream. NITROUS OXIDE CRACKER TORONTO PROFESSIONALIt was not uncommon to hear from individuals who had been to parties where a professional (doctor, nurse, scientist, inhalation therapist, researcher) had provided nitrous oxide. Lynn of its non-medical use in Michigan 1970) found that use of the gas for recreational purposes was then prevalent in the US and Canada. Even so, its use in parties continued, with gas provided by medical professionals or restaurant workers, and by other legal or illegal sources.Ī report from Consumers Union report from 1972 (based upon reports of its use in Maryland 1971, Vancouver 1972, and a survey made by Edward J. When equipment became more widely available for dentistry and hospitals, most countries also restricted the legal access to buy pure nitrous oxide gas cylinders to those sectors. Until at least 1863, low availability of equipment to produce the gas, combined with low usage of the gas for medical purposes, meant it was a relatively rare phenomenon that mainly happened among students at medical universities. James described a man who, when under the influence of the gas, claimed to know the secret of the universe. The memory of this experience, however, quickly faded and any attempt to communicate was difficult at best. James claimed to experience the fusing of dichotomies into unity and a revelation of ultimate truth during the inhalation of nitrous oxide. ĭuring the 19th century, William James and many contemporaries found that inhalation of nitrous oxide resulted in a powerful spiritual and mystical experience for the user. Poet Samuel Taylor Coleridge described the effect as "like returning from a walk in the snow into a warm room". English chemist Humphry Davy offered the gas to party guests in a silken bag, and documented its effects in his 1800 book Researches, Chemical and Philosophical which investigated "nitrous oxide, or diphlogisticated nitrous air, and its respiration". Inhalation of nitrous oxide for recreational use, with the purpose of causing euphoria or slight hallucinations, began as a phenomenon for the British upper class in 1799, known as "laughing gas parties".
