You can trade the cigarettes, vodka, half the meat and half the sugar in the black market to get more of everything else.
I got to know a few elderly people here in northern Ontario who grew up during the war years. They didn't exactly have to ration things but things were definitely in short supply. So they ended up just either not drinking as much or giving up smoking because they were luxury items ... then use your savings to buy more of everything else.
And as an Indigenous person ... my parents grew up with very little. But you could live for months if you had good supply of flour, lard, sugar and tea. There is even a drink we made called tea ploss where you just made really strong tea, then mixed in flour, lard and sugar to make a quick energy drink without much fuss in the cold wilderness. Supplement all that with wild food and you had a healthy long term diet.
