For me:

Pros: none

Cons: I fear it will trigger a full blown psychotic episode and wipe out all the progress I've made. I'm very sensitive to weed. I don't smoke it, but many times before my recent severe episodes I have been around people smoking it. I felt an ominous heaviness, and strange like I was standing outside my body. It pushed my paranoia buttons and I found myself becoming very distrustful of others. I just don't like where those experiences lead, so I steer well clear of weed now.
