Every morning before work he goes into the bathroom for almost half an hour. I noticed that his old track marks are red and bruised. When I asked him several times why, he told me that they sometimes change color. When I go into the bathroom I noticed cups of water sitting around. The other day there was a black residue on the toilet cover and toilet paper with small amounts of blood on the floor next to the toilet. I also noticed that he's not in there brushing his teeth because he kisses me before he leaves and I checked his toothbrush once and it was unused. I'm scared for him because he has a past of shooting that sh*t and morphine. Someone please help! Thanks<3
