You would still have to get it through the mail. If customs stop the package and it contains illegal stuff, there can be consequences. Like being locked into a psych ward if you are already known in mental health care as suicidal. I'm not OP, but that is the reason why I won't do SN, as I am too scared to buy it.
I am thinking about ODing outside during winter. People die here from getting drunk and falling asleep outside every now and then. As I will be ODing at the same time I will probably not be awake for the blissful part of hypothermia though... I think the part before you get delusional can be difficult though, the heavy shivers of freezing cold isn't pleasant.
It was about 6 or 7 C here last night so I opened all the windows got wet through and tried sitting there to see what it was like - shivered like hell.
So I thought maybe when it's colder get in a cool bath with bottle of whiskey, sit in it til it goes cold so core body temperature is dropping, then sit in room with all windows open. Keep dipping in bath as necessary. Fall asleep. Done.
Lots of old people die every year from hypothermia in cold houses because they have to choose food or the heating on.
Yes that's what our wonderful society brings them to.
In 2017 in the UK there were 46,000 excess deaths of old people in winter time. Only needs to be less than 10C.
