The Length of Time Laughing Gas and Whippets Stay in Your Body
Laughing gas seems harmless enough, given that it’s commonly used in the dentist’s chair to take the edge off discomfort during drilling. Most people wouldn’t cite it as a problem for addiction, but that is proving not to be the case, with ‘recreational’ brands like Galaxy Gas being used and abuse nationwide.
As nitrous oxide increases in popularity, so does the risk for addiction.
This leaves many people experimenting with this drug wondering: How long does nitrous oxide last in your system if you use the drug recreationally?
Nitrous oxide is a central nervous system depressant that carries serious long-term consequences with recreational use. Its half-life is very short, though, lasting just five to ten minutes. After an hour, it is no longer detectable on blood or breath tests.
While it may not be detectable in most instances, this does not mean that nitrous abuse cannot become a serious issue for those who become too reliant on this powerful inhalant.
But no matter your reason for using laughing gas, Purpose Healing Center wants you to know that help and healing from this form of drug use is possible. Our team offers comprehensive treatment plans tailored to each client, ensuring you receive the targeted help you need.
Below our resource offers a complete breakdown on how long nitrous lasts in your body, along with a few reasons why you might want to consider professional help for nitrous oxide addiction.
What are the Long-Term Effects on the Central Nervous System from Inhaling Nitrous Oxide?
Many people don’t associate nitrous oxide with a drug that can be abused, but that’s starting to change as it becomes more widely available. More often, it’s being sold in large canisters with colorful branding marking it as Galaxy Gas. Purpose Healing Center is seeing more people seek help for N2O than ever.
Why is it so dangerous for recreational use, and why should you avoid this appealing packaging?
Nitrous oxide sedation acts on the central nervous system and causes some serious consequences here. It depresses nervous system activity, altering neurotransmitter systems within the brain. When these systems are disrupted, you get the sense of euphoria that most seek out with nitrous oxide.
The problem is that long-term use leads to damage to the nervous system. It renders your vitamin B12 inactive. It also results in demyelination, which prevents nerve signals from crossing from one neuron to another, leading to serious effects such as muscle weakness and coordination issues.
Inhalant addiction poses significant health risks just like other substances known for addiction.
What is the Half-Life for Nitrous Oxide Sedation?
Inhaling nitrous oxide directly comes with an array of side effects, most notably a sense of euphoria. But just how long can you expect that high to last?
The good news for many people is that inhaling nitrous oxide has very limited long-term effects. You can inhale the drug and experience its effects only for a few minutes at a time. When you stop using nitrous oxide, your body begins to expel it from your system through exhalation.
The half-life of a drug is the amount of time it takes for half of the drug to leave your system. Nitrous oxide has a very short half-life, ranging from five to ten minutes. This can be shortened if you have the capability of using pure oxygen to expel it from your lungs and body.
Keep in mind that it takes several half-lives before all physical and mental health issues disappear. If you need to drive or operate heavy machinery, it’s recommended that you wait about an hour.
How Long Do Inhalants Stay in the Body for Drug Tests?
Just because laughing gas and whippets have a short half-life doesn’t mean that you’re home free when it comes to drug tests. As nitrous oxide leaves the body, it may still linger and be detected on breath tests or even blood tests.
N2O can stay in your system for up to one hour and is detectable on breath and blood tests during this time. If you’ve recently undergone dental procedures or received excessive nitrous oxide, wait for it to clear before testing. However, it typically does not appear on urine tests or hair analysis.
What are the Long-Term Consequences of Inhalant Abuse?
Because nitrous oxide doesn’t show up on many drug tests and clears your system quickly, many users will fail to see that there are still long-term consequences to drug abuse. You might be surprised at how it can impact you when you start using it for recreational purposes outside of dental appointments.
Some of the long-term effects of inhaling nitrous oxide regularly include:
- Low levels of vitamin B12
- Paralysis, foot drop, or difficulty with coordination and walking
- Tinnitus
- Incontinence
- Psychological symptoms like depression and psychosis
Too much nitrous oxide leads to severe consequences. It can be safely used under the supervision of a medical professional, but repeated use recreationally may require medical attention due to some of its long-term effects.
How Do Withdrawal Symptoms Affect Physical and Mental Health?
Are you ready to admit that nitrous oxide use has gotten out of hand? While it can be a powerful tool for pain relief in the dentist’s chair, you may find it challenging to quit using recreationally. There are some serious withdrawal symptoms for laughing gas, similar to other drugs.
During the first few hours or days without whippets, you might experience some of the following physical symptoms:
- Feelings of weakness and exhaustion
- Sweating
- Tachycardia
- Nausea
- Yawning, runny nose, and watery eyes
- Eating more and gaining weight
- Muscle aches and pains
- Fever
- Severe headaches
- Seizures
- Psychomotor retardation (slowing down of your thoughts and actions)
However, mental health symptoms can also surface in the early days without drug abuse. For example, you may feel more restless and agitated. Depression and anxiety are common, along with hallucinations and vivid dreams.
Because of the severity of withdrawal symptoms, you may want to enroll in a medical detox for a few days. Purpose Healing Center’s medical team can monitor you for troubling symptoms and alleviate discomfort through effective medication management. You don’t have to walk this path alone.
