• Eight years after first using the drug, Oliveri woke up with pins and needles and was unable to walk.

• Experts worry about the potential harm of nitrous oxide amid the rise of super-sized canisters.

When Vito Oliveri first tried nitrous oxide in his 20s, the legal drug quickly gave him a euphoria that, years later, temporarily paralyzed him and his fiancée, leaving him unable to walk his four dogs. I didn’t think

Experts are increasingly concerned Nitrous oxide and its potential harmAmid the rise of super-sized stainless steel canisters that hit the market to “deliberately target” recreational users, especially around 2017, according to a recent report, European Drug and Drug Addiction Surveillance Center report.

“Maybe every five or six years you see a patient who has had a stroke from taking cocaine. But every week you see this on the ward. From my point of view, this is actually a bigger problem.” ‘ said Dr David Nicholl, a consultant neurologist at the Sandwell and West Birmingham NHS Trust in the UK. sky news March 1st.

When Oliveri first took the drug, he attached a silver lipstick-sized capsule containing 0.2 ounces of nitrous oxide to a whipped cream dispenser and filled a gas-inhaling balloon. .

According to Oliveri, “small crackers” taste bad, but large cylinders are more convenient, tasteless, and produce a stronger sense of euphoria.

Laughing gas can inactivate vitamin B12 in the body

Nitrous oxide can paralyze a person because it inactivates and destroys nerve cells in the spinal cord. Vitamin B12is essential for maintaining the inner lining of nerves, Alistair Noyce, a consultant neurologist who works at a hospital in London, England, told Insider.

Noyce, who is also a professor in the Preventive Neurology Unit at the Wilson Institute for Population and Health, said that nerve damage can cause tingling and numbness in the affected body part, with symptoms varying in severity depending on the degree of damage. Varying Degrees. Queen Mary University of London.

People can also lose their balance because the signals that tell the brain where the body parts are located are not properly transmitted.

Struggling to balance from nerve damage caused by nitrous oxide, Oliveri falls when a dog jumps on him or pulls on his leash. He currently sends his two dogs (a Chocolate Labrador and a German Shepherd) to his dog daycare once a week to give them plenty of exercise.

Oliveri shared his story to raise awareness of the dangers of using nitrous oxide.

“Bottles of alcohol have warnings, cigarettes have warnings telling you what will happen, but nothing about nitrous oxide,” Oliveri said.

Doctors have seen people in their teens and twenties disabled by nitrous oxide.

Possession of nitrous oxide is legal in most countries, but some countries make it a crime to supply nitrous oxide for recreational purposes.

The Netherlands recently banned its possession and sale due to concerns about nerve damage and traffic accidents by people driving hikers. Also, the UK, where it is illegal to sell but illegal to own, could soon be a possibility. follow.

in the United States, New York state bans sales In 2021, there is also the risk of abuse, and recreational use is a misdemeanor in California.

People who use it frequently or lightly rarely get nerve damage, but Noyce says he’s seen patients experience it with one use, but those cases occur randomly. I don’t know if it happened or if it happened by chance. For some reason it’s easily affected.

Noyce said people, mostly in their teens and 20s, were “really very disabled” from the high doses of nitrous oxide in hospitals, and those who needed to use walkers or wheelchairs, incontinence or unable to get an erection.

Noyce said there was no consensus on the definition of “frequent use,” but broadly speaking, one could say that someone uses 10 to 15 or more canisters more than once a week. Stated. researchOn the other hand, classes at the Dutch Poison Center inhale more than 50 balloons in one session.

If you experience symptoms such as numbness, unexplained incontinence, or erectile dysfunction, stop taking this medicine, seek help immediately, and tell your doctor that you are using this medicine. Vitamin B12 injection “It’s very important,” Noyce said.

“Some people recover, some people don’t,” he said.

extra large cylinderis easier to use, but more dangerous

Oliveri first tried the drug when he was 26, partying with colleagues at a cannabis farm in California before meeting Schford.

He took it at parties for about a year, stopped until he moved to Portland in 2020, and bought super-large cylinders containing 20 pounds of nitrous oxide (equivalent to 1,600 0.2-ounce capsules) and costing about $400 each. discovered.

Since cylinders were not available in his area, he used 400 to 500 canisters a day for about a year to achieve the same euphoric effect.

“As soon as they run out, oh, we need more,” he said.

Noyce believes super-large cylinders are more dangerous than canisters. Screw the small canister onto the end of the dispenser and turn the valve on the large cylinder to inflate the balloon without having to awkwardly twist it every time.

Nitrous oxide can cause psychological dependence

Schford first tried a small canister of laughing gas on the couple’s first Christmas after meeting at a cannabis dispensary in 2018. She immediately liked it too.

But it wasn’t until June 2021 that the company began selling super-sized cylinders in Portland from 10am to 10pm daily.

The couple purchased the cylinders to satisfy their needs even when they were rushed to the hospital after being unable to walk due to nerve damage.

According to Noyce, nitrous oxide heroin but can cause “elements of” psychological dependence.”

“Patients endorse it craving it when they are not taking it, being irritable, always chasing the same original sensation, which leads to ever-increasing amounts.

Oliveri said the couple shared about two super-large cylinders a day for weeks, pausing only if they were vomiting or had flu-like symptoms.

“The euphoria only lasts for 10 to 15 seconds, after which you want to do it again,” Oliveri said.

Not only did he have health problems, but he was in financial trouble. Oliveri said the couple could spend up to $1,300 in one day.

Oliveri said he spent $20,000 on credit cards and $50,000 in cash in six to seven months.

With savings gone, Oliveri now works for a delivery service.

One day, Oliveri wakes up unable to walk.

Oliveri first realized something was wrong in April 2022 when his legs started shaking uncontrollably and he struggled to stand still. Unknown to him, this was a sign of nerve damage from nitrous oxide.

A month later, the couple used two extra large cylinders before a flight to Mexico. Oliveri’s legs were so shaky that he had to borrow an automatic chair to move around the resort.

By June 2022, pins and needles have gone “extreme.” One day he was numb from the navel down and could not walk.

He was with Schford, but had to call a friend to help him get in the car and drive him to the local hospital.

Oliveri said it took eight weeks before he could move around the house with a cane, then another five weeks before he could walk without it, but his ankle was still “fully functional.” I have not”. He “stumbles”.

Oliveri said it was his supplier who first told him that the drug could inactivate B12 after Oliveri noticed that he was “wobbly.”

“Prompt treatment with B12 injections will probably maximize your chances of recovery, but continued use will not protect you. are trying to prevent it from being harmed, but it’s not believed to be effective, according to Noyce.

The couple tried to stop using the drug after Oliver returned home, but was unable to do so.Five months later, in November 2022, Shufford was hospitalized for 17 days because he could no longer walk. She needed six weeks of physical therapy before she could walk without her cane.

The couple tried to quit smoking again and did so for a month, but began to feel stressed, bored, and craving that euphoria.

After a recent three-day binge, Oliveri said he was “pretty upset” about his drug use as he found it difficult to walk again. The couple can’t fully bend their ankles up and down or move their toes properly, but they do exercises to improve that.

As of March 16, the couple had been drug-free for several weeks.

“We’re really trying to make it through now. We can walk now, so we have to get ahead of that,” he said.
