Nitrous oxide (extra generally often known as laughing fuel) is a broadly used drug within the UK and plenty of different European nations. This colourless, candy tasting fuel has been used for over 100 years recreationally and in medication as an anaesthetic and for ache.
Nitrous oxide is simple to acquire and comparatively inexpensive, assembly the 2 drivers of drug use – value and availability. The brief appearing results embrace euphoria, heightened senses and a slight feeling of disconnect from the physique. It’s inhaled utilizing balloons or small canisters known as ‘whippets’.
The drug is utilized by individuals of all ages, however younger individuals make up most of these reporting use. Amongst 16-59 yr olds, 1.3% reported utilizing nitrous oxide in contrast with 3.9% to 16-24 yr olds. As with all details about drug use it’s troublesome to be exact in regards to the numbers of individuals utilizing nitrous oxide and the way often they use it. We all know that some individuals will naturally be reserved about admitting to utilizing a drug; fearing they are going to be stigmatised and/or get into bother.
As with all medicine, there are some dangers related to nitrous oxide use. It’s these dangers which have prompted in depth media consideration during the last yr. The UK authorities has responded to considerations from some clinicians in regards to the potential harms from utilizing nitrous oxide by updating legislation that makes possession of the drug a category C offence.
Use and provide of nitrous oxide was already restricted beneath the Psychoactive Substances Act, a subject lined by fellow Elf Professor Harry Sumnall in a earlier Psychological Elf blog.
Though many of the media consideration has centred on the dangers to well being comparable to neurological harm, there was little dialogue in regards to the potential for dependancy following use. So, a latest evaluate exploring this facet by Again and colleagues (2023) is well timed.

Nitrous oxide is simple to acquire and comparatively inexpensive, assembly the 2 drivers of drug use – value and availability, however is it dangerous for individuals who use it recreationally?
Strategies
The authors carried out a literature evaluate of research that investigated leisure use of nitrous oxide moderately than medical use. Nitrous oxide has been used medically as an anaesthetic for over 100 years.
This evaluate of the out there literature aimed to get details about how addictive the substance is when utilizing the Diagnostic and Statistical Guide model 5 (DSM-5) standards. This contains eleven gadgets comparable to tolerance to a drug, craving and withdrawal signs. DSM standards are broadly utilized in analysis and by clinicians to evaluate people and their use of a drug or medicine to determine whether or not there’s a drawback.
The authors included each human and animal research of their literature search.
Outcomes
Having reviewed the literature and cross checking with the DSM-5 standards the authors concluded that nitrous oxide use did meet 4 of the eleven DSM-5 standards for dependancy. The 4 had been:
- Criterion 1 – utilizing extra of the drug than meant.
- Criterion 3 – spending a considerable period of time utilizing the drug.
- Criterion 6 – experiencing social or interpersonal issues.
- Criterion 8 – doubtlessly bodily hazardous use.
It is very important level out that every one of those had been for these utilizing nitrous oxide closely, i.e. often and or at larger doses. Though heavy use will not be exactly outlined by the authors, they do point out that lower than 3% of these utilizing the drug achieve this no less than as soon as per week, with the ‘heaviest’ customers inhaling 10 or extra photographs a day.

In keeping with this evaluate, heavy customers of nitrous oxide might meet a number of the DSM-5 standards for dependancy.
Conclusions
The recognition of nitrous oxide has grown in recent times as demonstrated by the empty canisters that litter many streets throughout the UK. The drug is usually perceived to be innocent or no less than low danger, barring the rarer instances of neurological harm that some individuals have skilled, nonetheless its potential for dependancy will not be nicely understood. This examine makes that facet the main target of its investigation.
The authors assert that primarily based on their findings nitrous oxide ought to be thought of to be addictive for these utilizing the drug closely because it meets 4 out of the eleven DSM-5 standards. Though they do say that there are limitations with the research they reviewed and included.
Excited about the place nitrous oxide matches into the hierarchy of drug hurt, it’s nonetheless one of many least dangerous of all of the broadly used leisure medicine. The one sure-fire option to keep away from hurt from medicine is to not use them within the first place, however that’s not an efficient or lifelike method, regardless of successive governments basing their drug insurance policies and messaging on that flawed thought.

The recognition of nitrous oxide has grown in recent times, however its potential for dependancy continues to be not nicely understood.
Strengths and limitations
The authors are slightly extra candid in regards to the limitations of the research they discovered than in regards to the issues with their very own examine. There isn’t any point out or rational for why they selected to conduct a literature search moderately than a scientific evaluate. The latter technique is a extra dependable and in-depth manner of investigating the proof.
As talked about some key points of their examine usually are not clearly outlined comparable to what precisely is a ‘heavy’ consumer of nitrous oxide? Different necessary particulars are lacking comparable to inclusion and exclusion standards utilized by the authors of their search of the literature.
It is usually not useful to make use of the time period dependancy moderately than bodily or psychological dependence. It will have been slightly extra work, however would have produced a extra helpful article if the authors had adopted this terminology and explored the subject on this extra exact manner.
There are numerous limitations to the research included on this article which the authors describe. These embrace the strategies and sampling. For instance, some research had been primarily based on rats and lots of the research had been qualitative, or case primarily based. The authors rightly argue that bigger cohort research are wanted to attempt to reply the query in regards to the potential for dependence with nitrous oxide.
On a extra optimistic notice, this text is well timed and helps increase consciousness of a facet of nitrous oxide that has obtained inadequate consideration, specifically its dependency profile. Crucially the authors make the purpose in regards to the danger for hurt being higher for these utilizing the drug extra often and at larger doses.
![Future research should focus on the physical or psychological dependence that nitrous oxide users may experience, rather than the less specific term - addiction.](https://www.nationalelfservice.net/cms/wp-content/uploads/2024/01/shutterstock_2157730591.jpg)
Future analysis ought to concentrate on the bodily or psychological dependence that nitrous oxide customers might expertise, moderately than the much less particular time period – dependancy.
Implications for apply
Given the restrictions with the examine and the literature it’s primarily based on, it’s nonetheless not clear what the potential for dependancy is with this drug. This clearly limits the practitioner’s potential to advise anybody utilizing the drug that they encounter. This additionally restricts any public well being messaging or intervention looking for to scale back hurt given the restricted intelligence we’ve to date in regards to the drug’s potential addictiveness.
Maybe the very best we are able to say at current is that individuals utilizing nitrous oxide most often and at larger doses are on the biggest danger of creating issues, whether or not these are bodily or psychological. Frequency and dose are each components which might be markers for the potential hurt that many medicine trigger.

Folks utilizing nitrous oxide most often and at larger doses are on the biggest danger of creating issues, whether or not these are bodily or psychological.
