I've never been drunk, but I've tripped (shrooms) and have been blazed beyond recognition. Is it comparable to those two?
Being drunk is extremely inhibiting. You can't walk straight, find it hard to talk, completely lose all ability to make proper judgements, etc. Your balance is forgeted, if you sit or lay down you'll feel like the room is spinning around you. Despite this, everything is three times as much fun and you feel like you can do pretty much anything and talk to anyone. Some people experience euphoria, but for pretty much everyone, things that were weighing on you before tend to release. Though, conversely, sometimes liquor can turn people into sobbing messes because they lose a grip on their emotions.
So, no. It's not comparable.
