I've been trying to educate myself on weed. My difficult child, 18, is a constant user. It seems to make him very agitated, at least when he's at home. He says it makes him not depressed and helps his adhd. Of course I've seen the lazy affect. He was already lazy but now he's really lazy. He swears he's not on anything else and I home tested him and that was all it showed. He is failing school and is very combative and can be prone to being violent. It's a much longer story with many more issues but I have to get off right now. Just needing some advice if I should not be so worried if all he's doing is weed.
