Not very likely. Stimulants like that don't exactly stay in your system for very long and they don't have many lasting effects after they've worn off. They don't have the kind of pharmacological action like SSRI's and some other kinds of medications that can potentially tinker with a lot of different receptors throughout the brain and other nerves throughout the body. And even that's something I consider an unlikely risk, but comparatively, I think the risk is far less pronounced with most ADHD medications.

The biggest risk with stimulants would be if you took a really massive dose (or a lot of multiple doses) at once and if you caused some mini strokes or something. Mind you, this would have to be like 1/4-1/2 of a full bottle or something.

Edit: Also of course there's maybe some potential risk if you've been consistently taking heavy stimulants for 10-15+ years. But I was guessing that you probably hadn't taken them for quite that long, based on your wording.
