Same here, don't drink, smoke, or do any drugs. Still poor, so lol.
Story of my life. I don't smoke, and drink only cheep beer very rarely. Not wasting money on any earthy desire either... Still poor.
You can make your own alcohol!
Extremely cheap and potentially very good tasting.
You know what? I'll give you a recipe on a drink called "Mäsk" or "Kilju". This is an extremely easy drink to make and will be about 12% alcohol (it's essentially sugar wine btw):
1L water
200g sugar
A tea spoon of dry yeast
Take a 1.5L soda bottle, clean it properly.
Pour 1L water into the bottle.
Add the sugar.
Shake the bottle until the sugar dissolves.
Add the yeast.
Shake again.
Take of the cap.
Take a balloon and put around the opening of the bottle (don't just put the cap on again, because the CO2 the yeast produces will make the bottle explode).
(If you don't have a balloon, take a small plastic bag (preferably clear and strong), press the air out of it, and tape it around the opening)
Use some tape to make sure the balloon doesn't move.
Wait until the mixture gets clear (2-4 weeks).
Use a siphon (some kind of tube that can transport liquid) to put the liquid into new bottles.
Enjoy (or more like, try not to puke, because the taste can be pretty awful)!
Optional: Buy a bottle of juice to replace the water. Just make sure there are place in the bottle for the yeast to work, so pour some of the juice out (cranberry or apple works very well (and if you use grape juice it will essentially become regular wine)).
