How long has she been like that. If her breathing is normal and her pulse is normal maybe she just smoked too much. You said she was a good girl has she ever smoked before. Blunts may not be the way to go for first timers. Try placing a very cold rag on her forehead or on the back of her neck. If her vital signs aren’t normal you need to call someone. If they are give her a little time. How much did she smoke? I’ve heard of newbies sacking out before.
