Nobody said anything about buying "any old crap in a jar from dubious sources flogging 'cure alls' that will only offer the illusion of temporary relief while subjecting your body to all sorts of unknown side-effects." That's what you're saying. indeed, it is a false equivalence to equate all substances/drugs as whatever hyperbole you're talking about. All Parkinsons drugs, are drugs, whether you like it or not. And they work. Why? They target the underlying neurobiology. Drugs/substances/medications for stuttering do the exact same. To help you out, what I'm talking about are prescribed medications. Denying they exist, and work, is a denial of the current state of the medication literature on developmental stuttering. In addition, what you're talking about with "non-chemical solutions" is the current status quo. Take a look at this subreddit, do you see the suffering? Do you think the status quo is working? No. It is not. Not even the literature agrees with your statement. Things need to change.
