I am new to this site and am wondering how the conclusion of MJ being the direct cause for DP/DR. Have a doctor or scientist confirmed this and where are the studies , the reason i ask is I have this symptom and have always been told it was the result of anxiety and panic, I used MJ only breifly 25 years ago. If this can contribute to the cause how is this scientifically possible to continue with the symptom. Also my mom who was a panic sufferer had this symptom and trust me she never smoked. Is there a cure?
