This sets a really bad precedence. There are a lot of depressed individuals out there and I feel like sometimes people have suicidal thoughts but do not play it out because of how ultimately difficult it is to kill oneself. If this allows people to kill themselves with little to no pain/effort, I feel like people who choose to undergo this might regret it.
At least when you're killing yourself, there are always potential that you might not die, but this seems to be pretty effective There are stories of people who try to overdose but wake up the next morning and realizing that they don't want this to happen.
