A prior marijuana thing, perhaps, but cocaine, meth, you don't get into methland without people around you pretty much knowing what you are involved with. And we hang out with people with common interests, so I would bet a lot that he and mom have common interests. And it appears that she didn't have to take the 5 year old with her to the jail just to tell him she was done with him when she did find out about his drug convictions. I could not agree more, a surprise request for a hair test might, this time, get granted. And if she finds out too early.....or just for safety, do not let her know what you're planning. I've seen shaven heads, new extreme dye jobs, etc. All expended in the effort to beat the hair tests.
