Just a different perspective, a break. I think a lot of people get tunnel vision because they get stuck in their roles of daily life, and that leads to them being less understanding and empathic to others. But altering your consciousness gives you an opportunity to see things differently for a change.

The more perspectives you are regularly exposed to, the wiser you become.

People who responsibly alter their consciousness are going to have a more full picture of reality than those who don't. That doesn't exclusively mean alcohol, but also meditation, weed, psychedelics, mindfulness, lucid dreaming - all of these things make you wiser than those who chain themselves to one, singular perspective to view the world.
