My brother used to take cannabis (marijuana) hash and weeds, and he suddenly withdrawn it and after a week started showing psychosis symptoms which led him to not able to sleep for five days, continuously, only an hour day for these five days, after that I consulted a psychiatrist, he gave few medications, but I am not satisfied with the dose as he prescribed DIVAA OD 1GM, can this be cured without any medication and only with psycho treatment by improving the surroundings? I got him to a trip to lucknow and he got refreshed and recovered fully and when I shown his videos what he was doing during attack he was laughing and suddenly after 5 days of full recovery again a psychosis attack? What to do? Please help me.
