do you think that, in general, medication is successful in improving the agency of it's users?

i worry that medication harbors a reliance on drugs, and facilitates growth of a society in which drug-use is necessary to participate "normally".

if someone with ADD/ADHD has an opportunity to increase their agency, do you think that would increase their quality of life? the parent commenter suggested that mental illness (in the case of depression) might be the result of someone with healthy brain chemistry in a bad environment. but do you think that someone with healthy brain chemistry can demonstrate an attention disorder as a result of their environment, and would be more able to improve their environment through medication?
