I need to know an answer to a question I

I need to know an answer to a question I have about meth and how it looks when you use it in case I need to go to the ER because I feel like my throat is closing up so can someone who knows about that drug please comment or send me a message because I am starting to get extremely worried

If your throat is closing up, you should seek medical help. Asking strangers for help on an app doesn't seem like the best idea
