Replying to NS, is there any legitimacy to this

So basically this girl in my school smoked some weed. Well she thought it was weed.... Here's the story. Her and a friend smoked with some random kids from another school, both the girl and her friend apparently felt "paralyzed" while high. A few days after, they still felt strange, and the girl said she was feeling "weird lapses in time" as well as having anxiety attacks. So this girl goes to the doctor, and the doctor tells her she has some weird disorder with imbalances in her brain, somehow caused by weed? So she's apparently being put on medication and shit. But here's something weird, her drug test came up clean....

So when I first heard this I thought it was complete bullshit, some noob just got too high (this wasn't her first time smoking). But was it laced? Or Maybe no weed at all? That could explain the clean test maybe.... Idk I'm just really stumped, gentle, beatifily marry jane could never harm someone like this, so wtf is going on with this chick
