My child has spitting spells lightly constantly, he has hesitating movements at times sort of a tic. He goes through these rituals of moving back and forth and opening doors way before he has to leave to go some where. he has a hard time getting in and out of the car but eventually does it. He has tested positive for mariijuana, but I have never seen these types of reactions on people that were stoned before. He is ADHD and has been on vivanse to help him in school. He is 17. He is very irritable in the morning hard to get up always running late. Poor grades mostly just because he doesn t hand in assignments. He actually might have even done the work just doesn t bother to hand it in. The condition seems to be getting progressively worse. The testing was done mainly to adjust his meds. He has alergies as well and the Allergist is where the test was taken and sent to the lab. Marijuana was the only street drug found on the test. But since that time about 2 months ago things are getting progressively worse.
