My son who is 28 and has been living with me from the begining of January i am sure is taking drugs - he is moody,agressive has very dialated pupils -- hasnt been to work the last week comes home early hours of the morning - doesnt look me in the face - i questioned him yesterday and this caused a hugh fight and he denied it -- with result i ended up kicking him out of the house.He was very abusive - this is not the son i know at all. I do know that at times he smokes weed and he does have a problem with alcohol but the way he is acting now is bad.His ex wife said he is usindrugs but not sure which,he is stealing.He told me he never wants to see me ever again.He has pushed his brothers away,he got divorced and now its me - i was not made aware of his addiction until he had to move in with me and when i questioned him he denied it and i told him to go and look in the mirror at his eyes and his anger.What is it he could be taking he has moved but where he is i do not know.I couldnt handle his moods,him disappearing at night coming home at 5 in the morning having a accident on his scooter - something tells me there is a drug problem here and now he must bang his head is what everyone tells me.
