Why is there no alcohol?

As the title says. I think it would be fun to have that as a consumable. Like, Canadian whiskey.

It can warm you up temporarily, but it operates like an energy go drink, and after a certain amount of time it stops working. It bottoms out your temperature and energy, and gives you a headache.

Or if you have a bite, you can use it as an antiseptic in a pinch, but it has some sort of drawback.

It could be a strategic addition that could be fun to use. Thoughts?
