Nootropics on a developing brain

can damage the brain

What exactly do you mean here? I thought only extremely high doses of modafinil are neurotoxic and getting to that level would be taking 4500mg+? The only neurotoxic thing I see is the Adderall/Amphetamine use he has going on. Which by the way OP, Adderall is actually bad for your brain, it causes damage that is thought to be irreversible over long time spans.

This might be worth a look.

If you want to reduce damage caused by Adderall usage, here's a longecity thread on it.

Here's an excerpt you might want to look at:

Concerns have been voiced that, in addition to neurobiological adaptations, prolonged exposure to amphetamine could damage components of the central nervous system. These concerns arise, in part, from evidence that exposure of experimental animals to acute, high doses of amphetamine or methamphetamine produces damage, generally referred to as “neurotoxicity”, to dopaminergic neurons innervating the dorsal striatum (caudate-putamen). The evidence for neurotoxicity in rodents derives almost exclusively from studies utilizing very high parenterally administered doses of the drugs, typically administered in a “binge” pattern; i.e., four successive injections at 2-hr intervals 41, 42.
