Mental disease is a disease too. The options are either to have ADHD, which is a potentially very destructive disease, or to have a low-grade dependency on stimulants with few side-effects that can be severed in a week or two.

Of course, many medications that aren't psychotropic fit the bill. Corticosteroids, for a common example, lead to physical dependency too. Most medications lead to some kind of physical dependency after prolonged use, it's just sometimes of very low grade.

The second option is much better from any pathological point of view.

To note, perfect health doesn't exist. We're all broken in some way :)
