ok so frist of all, there is no drug yet discover to treat stuttering so yes people should not go for drug. Secondly if some day, drug will be discovered then it is not wrong thing, humans has achieved many unobtainable thing like impossible, the day will be come and future stutterers will not suffer like us. Not every stutterer has resources or sufficient life to focus on treating stuttering by techniques therapies and all, we requrie guidance through out treating by therapist or other specialist to perform techniques correctly, but they all ask for lump sum of money, not every stutter can afford, and many are living in the places where there is not even awareness about stuttering, so it is very complicated, not that simple, so you can be frustrated or sad about people talking about drugs, but it does not really matter.
