"Son#1 (my only son) was then invited to take urine and hair drug tests and passed with flying colors."


Pardon me, but from the tone of your post, why do I think that "invitation" was not voluntary?

Did he volunteer to take a test or did you compell him to do so?

Please do not misunderstand me here, I understand how betrayed you feel, but from both an ethical point of view and in terms of the basis of trust between you and your son that concerns me.
