Oh, I can answer this one! Unfortunately, I lost a very close friend to suicide so I learned a lot about it.
Suicide is nearly always an impulse crime. The small number of people who systematically plan their suicide are nearly all people with, sadly, good reasons to want to die, nearly always unbearable pain with no possible cure, and almost none of them are teens.
This machine is not a threat to teens.
I might add that even though I believe in the right to euthanasia and l live in a country where it's legal, I find this machine creepy and dodgy.
