Schizophrenia symptoms:

  Hallucinations (e.g., hearing voices), delusions (e.g., believing one has special powers), disorganized speech and behavior, reduced emotional expression, lack of motivation, withdrawal from social interactions, problems with attention, memory, and decision-making 

Yep. Had nearly all of the above when I was bored out of my mind and smoked every single day during covid. I was working remotely and was high half of the time I worked. That went on for about 1 year. Thank goodness I was a mature adult when I first started and could eventually remember that life was better without weed. Sober for 1.5 years now.

I highly recommend r/leaves to read other people's stories trying or wanting to quit weed.

Edit: For those wondering, after being sober for 1.5 years, I'm pretty much back to my old self. My memory took a while to come back but it's drastically better than it was when I first quit. I feel much more motivated in life. My relationships with family and friends are better and so is my physical health. I was smoking about 0.5g - 2g/day for 1.5 years.
