Nembutal and legal assistant dying is currently available in Switzerland through non-profit organizations Dignitas and Pegasus. Also, people do not have to be terminally ill, just adults who are capable of making decisions for themselves. It's also legal and available in 11 other countries. There's also currently talk of expanding to include many more than just the terminally ill in countries such as Canada and the UK.
VAD and MAID are here already, and if you can afford it, you can travel to Switzerland and have it done very quickly. It's also the future in all developed countries, we just need to speak up and push to speed up the process.
It's true, there should be no reason for people to have to resort to the various risky, painful, and inhumane methods of suicide to escape their unrelentingly suffering. Dogs and cats have had the method and the right to a peaceful escape from their suffering for eons now, just not people.
If everyone keeps their mouth shut on this issue, then it will likely take 20 years for legal assisted dying to be available for all who need it. But if people speak up, it's possible that it could happen in as little as a few months. There is no reason why millions of people need to continue suffering intolerably for another 20 years!
