Home › Blog – Gladstones Private Rehab Clinic › Hippy Crack/Nitrous Oxide Addiction: An Overview of its Effects, Withdrawal Symptoms, and Treatment Options
Nitrous oxide, often referred to as ‘hippy crack’, ‘laughing gas’, ‘whippets’, or ‘NOS’, has seemingly come out of nowhere over recent years, overtaking nearly all other drugs in popularity among teenagers and young adults aged 16 to 24. According to the UK Office for National Statistics, 3.9% of people in the aforementioned age group were abusing nitrous oxide, with only cannabis remaining more popular (Glasper). In many Western countries, it is becoming increasingly commonplace to find evidence of nitrous oxide abuse; the discarded aluminium canisters and balloons in parks, festival grounds, and other places where young people gather.
While nitrous oxide-related deaths pale in comparison to those of alcohol and opioids with roughly 36 deaths per year recorded between 2001 and 2020 (Glasper), its reputation for providing a ‘harmless and short-lived burst of euphoria’, along with its ease of availability and growing popularity, all contribute to growing use numbers. This has led to a recent government clampdown on the drug, and as of the 8th of November 2023, nitrous oxide has been reclassified as a class C controlled substance with sentences of up to 14 years for dealers (GOV.UK).
The rest of this article will aim to put nitrous oxide abuse and addiction into context; explaining the history of this 140-year-old anaesthetic, how and why it’s abused, the long-term effects of NOS abuse, and treatment options.
Nitrous oxide was originally discovered more than 250 years ago by English chemist Joseph Priestley in 1772. While many scientists studied it further, it wasn’t until 1844 that Horace Wells, a dentist, discovered its anaesthetic properties and propelled it into the spotlight in the medical community. By combining nitrous oxide with oxygen at the right concentrations, physicians could produce a state of euphoria, analgesia, and a reduction in anxiety in their patients, especially useful in the dentist’s chair, during labour, and other minor medical procedures. This made many procedures much more bearable and paved the way for the development of modern anaesthesia.
Within a medical and narcotic context, nitrous oxide is classified as a dissociative anaesthetic. This type of drug distorts the perception of sight and sound and produces a feeling of detachment (dissociation) from the environment and the self. Other dissociative anaesthetics include ketamine and PCP. As a recently-classified class C drug in the UK, nitrous oxide is still available for legitimate uses in the hospitality (cream guns), medical (anaesthetic), and other industries; however, those in possession of nitrous oxide cartridges with the intent of misusing and unscrupulous dealers are subject to a fine and/or imprisonment.
When inhaled, nitrous oxide produces a short-lived (typically 1 to 5 minutes) feeling of euphoria and relaxation. The feeling has been described as being ‘happy drunk’. N2O works by interacting with the central nervous system. It inhibits the action of the NMDA receptors, which produces an analgesic effect by preventing the transmission of pain signals. It simultaneously stimulates the release of endogenous opioids (naturally occurring painkillers in the brain and CNS) and dopamine (the neurotransmitter responsible for pleasure, satisfaction, and motivation), further enhancing the drug’s analgesic and euphoric effects. Finally, nitrous oxide also inhibits the brainstem’s respiratory centre, which increases CO2 blood levels (Gillman and Lichtigfeld) and contributes to the overall ‘high’.
Nitrous oxide doesn’t form the same sort of physical dependence experienced by opioid and other hard drug users; however, it can easily lead to psychological addiction and dependence as it interferes with normal dopamine levels.
Nitrous oxide is taken by emptying an aluminium N2O canister into a balloon or plastic bag and then inhaling the gas. This colourless and odourless gas’ effects kick in almost instantaneously, causing feelings of:
Nitrous oxide has a very short half-life within the body, and most users return to their normal selves after roughly 5 minutes. On the one hand, it’s a blessing that the N2O doesn’t stay in the system causing harm over an extended period of time, but on the other hand, the short duration of its effects causes many users to ‘pop multiple whippets’ in a single session. A 2024 study of patients suffering from harm related to nitrous oxide abuse found that some used up to 500 canisters per session (Crisp).
Medically speaking, a single hit of N2O is extremely unlikely to have any lasting negative effects on the brain or body; however, its effects on one’s perception and motor skills increase the risk of accident or injury. Extra-large hits or too-frequent N2O inhalation can also lead to a drop in brain oxygen levels, leading to a loss of consciousness and possible injury. Other immediate risks of nitrous oxide abuse include problems with the law if caught with the canisters and frostbite when N2O is sprayed directly into the mouth.
Regular or ongoing nitrous oxide abuse can have serious and potentially irreversible health implications. Some of the more commonly reported long-term effects include:
Considering the potential severity of these effects, which could include paralysis and death, finding professional care for loved ones suffering from nitrous oxide becomes imperative. Whether you decide to go through detox and treatment at home or in a dedicated facility, quick and decisive action now can prevent devastating consequences down the line.
Fortunately, as a non-physical dependence-forming drug, nitrous oxide withdrawal is relatively comfortable and painless compared to alcohol or opioids. It’s not exactly pleasurable but poses little risk to your physical or psychological well-being. Nitrous oxide withdrawal symptoms are similar to the withdrawal symptoms experienced by chronic cannabis smokers and even heavy smokers giving up nicotine. The symptoms can be broken down into:
These withdrawal symptoms are usually not severe and are typically treated with non-prescription drugs such as painkillers and sleeping aids. The neurological symptoms can be expected to last for around a week after the last use, while the psychological and physical symptoms typically last for around two weeks. Depending on the individual, anxiety and some cognitive issues may persist for several weeks, especially in heavy users’ cases.
