Why is this such a concern to you? At some point, everything has _some_ risk, and this feels like you're putting a lot of guilt on someone else for making a medical decision they deserve to make on their own.
Pharmacology is not my main area of expertise but I used to do a lot of work in cardiology, and anything that increases the QT interval in the ecg increases the risk of Torsades de Pointes.
Rule of thumb is 5–7% more TdP risk per 10 ms QTc.
Quite a few adhs meds do this moderately, not enough to make an ecg mandratory.
I still believe that making medications the default for adhs is not warranted given the side effects, especially since in many cases it’s not clear if it treats the condition or just makes the lives of education professionals easier.
I, and millions other people, could tell you that it does immensely benefit with issues like executive dysfunction. Medication quite literally made the problem I had been battling for decades disappear instantly.
Associating adhd just with childhood is in itself an obsolete view that causes issues for people.
Lack of trust in delivery speed at work, friendships damaged by unintended slights and so on.
Even building habits that I could never have kept before is a grind. The fact that I now can build habits only places me at a neurotypical starting line, now habits still need to be built.
