Hi doc. My friend and me both were smoking ganja for few months and at the end we smoked alot and caught into withdrawal. Actually he got withdrawal but for him its very scary feelings he feels like everything around him is weird and detached unreal u beheving like a paranoid even he cant focus concentrate and he get very scared anxiously with this feeling. Is there have any medicine or therapy for this brain numbness ? Depersonalization derealiztion ? We were fine alot normal guys we just got this in withdrawal symptoms so will this go away or any cure? Cz job and study all stopped.
