What simple illnesses? Yes, it got extra media attention due to the fact that they have passed a bill for MAiD for mental illness (however hasn't been put into place yet as they are setting up protocols for specific mental illnesses, symptoms, criteria, ect.) but people who are extremely, chronically sick (just not terminally) still have a hard time getting accepted. The process can take a very long time, a patient may need to have numerous appointments with different doctors and specialists before being approved, and then a second doctor needs to confirm everything before getting officially approved for MAiD.
I'm not saying the process can't be more simple at times, but if your illness isn't terminal and death isn't expected in the foreseeable future, it isn't just a simple process, doctors aren't just "prescribing" this to anyone.
