Oops.
I have been willing to give him the benefit of the doubt up to now, because his initial defense was not outlandish. Aderal and other drugs used to treat ADHD can (no matter what NASCAR says) cause false positive tests for meth and other forms of “speed”.
However, this does not look good for him at all. If hi own step-mother is telling the truth then it probably won’t be long before other witnesses come forward.
If it was his mother, I would be more inclined to go along with you. But a step mother might have her own agenda here. I would still like to see a full disclosure.
