I have to take a drug test this Thursday (urine and hair). I don't illicit drugs but every now and then (4-5 months) I'll smoke a little weed with friends. Nothing crazy. I recently went through a breakup and found myself smoking a little more than normal and now I am worried I am going to fail. Here's my story;

The last time I smoked was exactly a month ago and it was probably about a bowl. I smoked about the same a week before that. And the same a month before that. I work out daily and sweat like a beast. I am female, and have thick light brown hair.
What are my chances of passing?
