A new 3D-printed mobile suicide capsule which performs euphanasia without the use of drugs has passed a legal review in Switzerland, and is set to begin operations in 2022.

The Sarco machine completes assisted suicide in 30 seconds by flooding the interior with nitrogen to reduce oxygen levels to just 1% and leaving users slightly euphoric before death with no panic or choking sensation.

Those intending to die press a button inside the capsule in their own time, and can undergo the process in any setting they choose.
