Kurt Vonnegut’s son Mark wrote about how pot made his Schizophrenia worse in his book The Eden Express. He was trying to be a Good Hippie so he kept using recreational drugs with his friends despite suffering terrible effects. I could very much relate. I really wanted to like pot and tried it over and over but it was always either horrible or barely tolerable. It’s not for all brains.
Even though it made me super negative about myself, I smoked pot all of the time with my friends as a teenager -- tons every day (well, grams) -- greatly exacerbating my depression. I finally figured it out when I was 19, and quit. With the exception of one hit in 1988, I've never used it again (in any form), and never will.
