hi all. i utfse'd and found nothing on this. where I live we can buy a cough syrup OTC which contains a mixture of codeine, diphenhydramine and ammonium chloride. i recently picked up a bottle for a brutal cough and started thinking 'hmmm, codeine and diphenhydramine? I'm worried, however, about the ammonium chloride concentration. is this substance even safe to ingest? thanks
