Good question I was wondering the same thing....

What if I’m just inhaling from a balloon?
Typically, inhaling a single breath of helium from a balloon will have the desired, voice-altering effect. It might also cause a bit of dizziness.

That said, there’s always the potential for other effects, including:

nausea
lightheadedness
passing out
Inhaling helium from a balloon isn’t likely to cause major health issues or kill you, but it’s not impossible. There have been news reports of some folks, particularly young children, dying from asphyxiation after inhaling helium from a balloon.

What about helium from other sources?
The majority of serious health issues and deaths related to helium inhalation involve inhaling helium from a pressurized tank. These are the same tanks used to fill helium balloons at events or party supply stores.

Tanks not only hold a lot more helium than your everyday party balloon, but they also release the helium with much more force.

The more pure helium you inhale, the longer your body is without crucial oxygen. Breathing in pure helium can cause death by asphyxiation in just minutes.

Inhaling helium from a pressurized tank can also cause a gas or air embolism, which is a bubble that becomes trapped in a blood vessel, blocking it. The blood vessels can rupture and hemorrhage.

Finally, the helium can also enter your lungs with enough force to cause your lungs to rupture.

@I_am_innocent you are not so innocent. Thanks for your explanation

I've just looked it up. You're welcome.

You're like fucking Quincy MD. Good job brother.

Poor Rupert Ruptured Lungs, life treated him unfairly

Please dont do it you're worth something and deserve to live!

Don’t do that, stay strong and get some help

Tried. Psych just told me it is part of an unrelated disorder I have (even though the symptoms I talked about are not even part of that disorder) and prescribed drugs which I am not going to take. God I hate mental health "professionals"

I will try again soon

It’s not worthy to die for some shitty things or people, never give up living, hope you’ll get well soon
