I had a friend in high school who took mushrooms and said they never felt like the same person since then. That statement was made in high school and reiterated in their late 20s. I don't know what dosage they took. I don't know if they had other mental health conditions, though it seemed like they had some degree of alcoholism. I have dealt with depression and have my eye on some form of Psilocybin treatment as a future option. But am weary due to my friend's experience. So I'm waiting for more expertise to be developed and the treatment to be validated and consequences quantified.
