Idk how it is for that person, but it's not a good thing for me. I see a crumb in a grout groove or something, and start thinking I must be the most disgusting person ever to exist. Next thing I know I'm scrubbing grout with a toothbrush and feeling terrible about myself. But weed doesn't affect me like it affects most people. It gives me a lot of anxiety, and I can't control my thoughts. That's why I just don't touch it anymore.
