Caffeine is lowkey the most normalised and profitable drug addiction in the world, and it doesn’t really even do anything. The whole ‘giving you energy’ thing is a myth, all it does it make you tired without it. That’s why caffeine legally has to be listed as a ‘flavouring’ on the packaging, despite nobody on earth having a clue what it’s supposed to taste like
Caffeine is not addictive in the technical sense.
