Eh this is kinda stupid but in chem, I inhaled some very concentrated hydrochloric acid on accident because everyone was saying there was a strong odor and I couldnt smell so I kept getting closer and took a deep breath and it was like 100x worse then smelling ammonia...........I was a lil out of it for like 30 mins or so with coughing and everything.......Im fine now but is there n e lasting effects? For n e chemists it was 12 molar
