He must be using a hell of a lot for his nose to get a hole in. Maybe in the morning as well. Im doing my best to stop coke. Im having it once a month. When its wearing off it sends you depressed and suicidal. I imagine hes told you as he is coming down wanting help.. but i could be wrong. But i doubt it, as it makes you do things like that and then be normal.the next day.
1st off if his nose is like that, he needs stop asap. I dont think its like heroin were u need weening off it. He needs to want to quit himself, and with his nose being like that id go see a doc, and get my self to a cocaine/narcs meeting straight away. He obviously is bad. Sit him down and ask him how long and how often and how much is he using. Tell him you want the truth or we wont able to fix this..
If he wants to quit he needs to.. delete all dealers nums out of his phone, friends and family who take coke. Come off all social media, and replace his routine with a new 1.. with new hobbies to replace his usual routine of having coke.
No drinking alcohol as well.
Does he go out alot?
