I absolutely love this idea

DM accidentally uses his roommate's THC gummies for underlings. The battle to kill the cinnamon roll is bloody and vicious as PC turns on PC for the glory and the sweet spoils.

And the boss has an attack that lowers intelligence and wisdom.

Anyone else here just play with no visual aids at all? When I first started playing D&D after finding the second edition books in my dad's closet, my friends and I just used our imaginations. No minis, no maps.

It's called Theatre of the Mind. I've definitely done it, and it has it's advantages (cheap, lower prep time) but I don't favor it nowadays. Especially in my last campaign, a swashbuckling pirate adventure, I tried to always have at least some kind of visual aid, because it's critical to that swashbuckling feel - the players can't swing from the chandelier if they don't know there's a chandelier.
In one campaign, we started out using tokens of some kind on a battle grid. However, as the campaign went on, we stopped using it. For most part, it went okay. However, keeping track of where everyone can sometimes be too much. In particular, my character, whose modus is either hiding or healing, sometimes both, lead us to a situation when even I forgot to inform of our DM that I was hiding behind a huge statue that fell over. I was too busy keeping the rest of the party alive that I forgot where I was. Thankfully, when it was brought up, our DM just asked me to do an acrobatics check to confirm that I managed to roll out of the way and another check to see whether or not I kept myself hidden.
Keeping track of everyone's positions also became less important because our DM got a bit more lax about imposing those area of effect rules.
Isn't that what the kids in Stranger Things did?
I tried doing this but I could never visualize the fight or what something looked like... Turns out I have aphantasia and had no idea for 24 years because I just assumed no one else actually "saw" images when told to imagine something either and it was just a phrase
It's called Theater of the Mind, I think. It used to be the way we played ADnD, but I guess that the newer editions pushed the minis-and-grid with their more tactical playstyles.

  Far from everyone, the game was born out of war gaming so maps and minatures have always been big in the community. I personally see theater of the mind more often these days than when I started.

Were NPCs delicious too?

You could use raw vegetables that most people won't eat raw to make them think twice about killing them.
You sure might avoid killing the quest giver if it was a raw onion
- I would eat a raw onion for the laughs

I do this too. Instead of minis, I tape a drawing onto a Starburst and whoever kills the monster gets to eat the Starburst. I'm gonna have to get something like a donut for the boss fight at the end of the adventure I'm running rn.

Did the DM get to eat the player's minis?

A murder hobo s'got to eat!

who was the saint playing a cleric?

- Our poor cleric almost never got to go offensive, mostly because my wizard had a 16 Dex and Improved Initiative, so that she could go first in most combat instances, and well, fireball is effective.
  When she did get to go offensive, boy howdy. She had Reach Spell, so all those touch spells just got a 15' range. She walked within 10 feet of a Boss cleric and hit him with a Harm.
- That could be a Dungeon Meshi meme
I'm playing a cleric in Baldur's Gate. I'm at the end of act 1, and just realizing she's supposed to have been a raging asshole the whole time.
