Sure. The early history of ritalin was the first sign to me that pharmatech industry owns their regulators. Check out the follow up research on 8-hydroxyguanine glycosylase as an indicator of oxidative DNA damage in response to the 2005 nih publications asserting no increased biomarkers, its somewhat surprising on both sides for Ritalin and the popular amphetamine alternative as well.

Yeah no I'm not buying it. Amphetamine, perhaps, but atomoxetine causing DNA damage? That sets off my "spurious results" detector, hard.
I'll look into it more but I've done deep research into all things psychostimulants and I have not seen any indication of genotoxicity of methylphenidate or atomoxetine. Amphetamine has a slight risk of increased oxidative stress due to making dopamine leak places where it shouldn't, and DA's electronic structure makes it prone to generating singlet oxygen and ROS, but it's typically only observed in really high doses, like the equivalent of hundreds of mgs per dose.
Like, maybe there's some increased ROS due to any drug that boosts DA/NA (oxidizing catecholamines produces ROS in general), but like, "ritalin causes DNA damage" is the wrong conclusion to draw from that.
Pls send some studies, very interesting.
