These are all really excellent answers.
I have a friend that has a 17 year old with some kind of disorder. Unfortunately he really hasn't had good doctors in his area. The kid is literally a genius. Vapes, pot, snorts crushed Adderol. He is so addicted that without it he can't eat or sleep. My friend says the child makes life at home as difficult as possible for them. He is a good kind empathetic person that I have never seen mad. Both very smart with degrees in various fields. They have a 2nd smart child normal child that is wonderful. It has come to the point they have to put the 1st son in some sort of institute to clean him up. The kid went so far to fake urine drug tests at home. They need to go to therapy every week. They believe he has personality disorder + ADHD. I feel bad for the kid and the parents. He is a genius and can be/do whatever he wants but the miswired neurology is killing him.
What a waste of his brains, if he lifes like that for long hes definitely going to lose some iq points. It will harm his neurology on top of the problems he already has. My sister has been addicted to drugs to cope with her undiagnosed autism for years, shes been in an institute to clean her up but continued drug abuse the day she got released, a lost cause really.
