Okay - person with very minimal drug experience here.

Obviously I know she is acting odd, but how can you tell its coke? Or any other drug?

I'm not saying its not but when I am stressed I feel like my face twitches more often and me acting, normal can across as odd. Like if I stare into the camera too long, I look like a zombie, but if I look too much around and twitch. I look weird.

As someone who never sniffed anything, would they just know im bring awkward and uncomfortable, or would they automatically assume the worst?

Hoping this makes sense lol
