I haven't posted here in awhile. My son quit college twice. Is home does not work or go to school. He will be 19 next month He smoked pot everyday many times a day for at least 3 or 4 years. He was totally clean for the last 3 months. He was on Lexapro 15 mg during this time. I guess it wasn't helping him too much. I told him he had to go back to the psychiatrist and he said he would go. I wanted him to speak to the dr. to see if we should increase the dose or put him on something else. he has a long history of mental illness. made the appointment and of course he wouldn't go. Then the worst thing happened after being clean for 3 months he started going out again and smoking. I know he was clean for 3 months cause he was always home. I got him the best doctors. that cost a fortune that weren't on my plan. He refuses to help himself. when he starts smoking it's all downhill. We went through so much with him I couldn't go tell you it would take to long. Police at the house many times , him grabbing knives stealing from us etc..... I was willing to work with him as long as he stopped smoking and went to the doctors. He refuses to help himself. Now he's back to smoking. That's it. It's time for him to leave. I am really afraid of what will happen to him..
