do they go off on there own a lot in the house? and does he appear to be dazed at points and say stuff and never know whats going on? if so then you get to kill him...ok so not really...but he does have a problem...and dont forget about bloodshot eyes
There are a couple of ways to tell if your loved one has a cocaine problem. Lack of appetite, weight loss, missing money. The best way to tell is by looking into their pupils. If your loved one is on cocaine the pupils in their eyes will be like quarters. Plus if you have been with this person for that long and suspect that there is a problem then more than likely there is. Good luck!
