My 18 yr old son has been smoking weed. We have caught him a few times. We have been all over him, tossing his room, going through his car, even testing him. Now he was suspended from school, a bag with residue was found in his car. This is a good kid good grades, athlete. He is looking forward to going to college. Although this is a terrible situation I'm glad it has happened. I'm hoping this is what it takes to make him realize this is a serious problem. I'm concerned that he has been very depressed the last few days. I'm having a hard time finding a balance between disicpline and support. He is upset yet angry.
