I was wrong
I tried to post this yesterday and I don't see it. No sure what happened.
Long story short. I knew my son used and abused marijuana. I've caught him and he's talked to me at length. He's never admitted using anything else. But his behavior has become more and more erratic and he's gone through a ton of money in the last six months. I assumed he had escalated to meth or something similair.
He's in the hospital now having been stopped by highway patrol last Fri. night. In a Christmas blessing from God the officer recognized that what was going on was not drug use but mental illness.
My son tested clean for everything, even alcohol and marijuana. He's in a psych ward now, being treated for paranoid schizophrenia (sp?) possibly the result of untreated bi-polar.
Be careful out there. I almost lost him forever.
