i just spoke to my p doc and i have her dr. simeon's number in ny and i might do a private consultation with dr. simeon. and she said that is it very common to get dp after smoking pot once or a few times, and my p doc gave a quick overview of my story and Dr. Simeon said that my case is very common and they are doing this study in Mt. Sinai where they take your blood to see if DP/DR is related to something in the brain. there is some other word for it but i forgot cuz when i hear new info i can't comprehend all of it, but this is a good thing. Dr.Simeon also doesn't believe in AP's for DP and doesn't think AD's work that much.
